- M.2 SSDs are tiny, easy to install and super-fast but did you know that they come in two different form factors? There are indeed both SATA and PCIe varieties of M.2. They are both long and thin and look a bit like a stick of chewing gum. But they are different. Text version of this topic: www.kingston.com/en/blog/pc-p...
Interface
Many people think the alternative to M.2 SSDs are SATA 2.5” SSDs, and while the 2.5 inch portion is correct, SATA actually refers to the storage interface. SATA and PCIe, or PCIe NVMe, are both types of storage interface that an SSD can use. The primary difference between the two is performance and the protocol, or language, spoken by the SSD. The M.2 spec was designed to accommodate both a SATA and PCIe interface for SSDs. M.2 SATA SSDs will use the same controller currently on typical 2.5” SATA SSDs. M.2 PCIe SSDs will use a controller specifically designed to support the PCIe protocol. An M.2 SSD can only support one protocol, but some systems have M.2 sockets that can support either SATA or PCIe. An easy way to tell the difference between the two drives based on appearance alone is the notches in the connection. SATA M.2 drives will have two notches, while PCIe will only have one. (Note: as of December 2022 Kingston shipped out the last of its SATA M.2 SSDs, the A400 M.2. We no longer make SATA based M.2 SSDs and going forward all our M.2 SSDs are NVMe.)
Performance
So what’s the difference between the two? The PCIe interface is generally faster, as the SATA 3.0 spec is limited to around 600MB/s maximum speed, while PCIe Gen 2 x2 lanes are capable of up to 1000MB/s. And if you think that’s a large difference, PCIe Gen 2 x4 lanes are capable of up to 2000MB/s, and Gen 3 x4 lanes of up to 4000MB/s. Not to say that speed is everything. M.2 SSDs using the SATA protocol will generally be compatible with a wider variety of systems and can be better supported in older models, plus they are usually more affordable when it comes to PCIe. Another thing to consider is that some motherboards don’t have enough PCIe connections to support multiple PCIe NVMe drives. You might have to decide on using the available connection between a graphics card or an NVMe SSD. Other times there may be PCIe lanes available but only a certain type of connection will be able to use NVMe devices at their full speed such as an M.2 connection.
For example compare the Kingston A400 SATA SSD vs Kingston KC3000 PCIe NVMe SSD. The A400 has two key notches, comes in capacities up to 480 GB and has up to 500 MB/s read and 450 MKB/s write - all at an MSRP of under $50. The Kingston KC3000 on the other hand, has one key notch here on the side, comes in capacities up to 4TB and offers 7,000 MB/s read and write speeds. The starting price for this drive is $100.
So to sum up - yes, M.2 SSDs can come in both SATA and PCIe NVMe varieties. PCIe is newer and faster, while SATA is more affordable and more widely compatible with older systems. What you choose is up to you, but I hope these basic guidelines helped a bit in your shopping journey.

3:21 Comparison of a SATA M.2 SSD vs PCIe M.2 SSD - Наука та технологія
The most concise and easy to understand comparison I've seen yet. Had me going back to check my new-build part bin to ensure that I had, indeed, purchased the correct components. Thanks, I can breathe easy now.
I just did the same thing 🤭😂
Just sharing, when it comes to SSD, 3 criteria u guys should know:
1. Form factor : 2.5" and M.2
2. Interface/slot/port : SATA and PCIe
3. Protocol : SATA and NVME
So is it possible to have an M.2 PCIe SSD using the SATA protocol ?
@@gottabepablo wouldnt you need the connection of the m2 to be sata (physically speaking) in order to use its protocol?
Thank you!
@@gottabepablo If you see an M.2 drive with two notches in the connector instead of one, I think that means it's either a SATA drive, or a PCIe drive with only two lanes. I think it's physically the same connection? There are M.2 slots that support both or only one, anyway. But the same drive can't do both.
@@whyjay9959 I thought SATA is not only just a physical interface but also a protocol implemented in software that has to do with the drive controllers. So although an M.2 drives connector is etched for the PCIe interface, can't it not be configured to use either the NVMe protocol or the SATA protocol? (not the physical connection/interface)
This is the best video explaining it easily I've come across on UA-cam. Well done.
agree.
Answered my questions 🙂
Plus she's hot, so that's nice
with one contradiction
Thanks a bunch, this is what I needed. While I had found another video explaining it. This one was much easier for me to understand.
Best tech vid I have seen in a long time. Accurate, concise and well presented. Thank you
Thank you so much for easy explanation spent last 30 min trying to figure this out on Google couldn't get a clear answer until I saw this, thank you
Happy to help!
thanks, i was so lost about this topic and this video really helped me
I have a M.2 SSD 500Gb for the OS and I am very satisfied with it... not expensive, very fast and reliable. With HDD my PC took between 1 or 2 minutes to fully restart, but with M.2, it only takes 17 seconds and it´s ready to go.
What pci version is required for the same..
@@dharmendra34061 it depends on what kind of motherboard you have and the type of PCIe slots it has. Older motherboards generally have a PCIe Gen 3 slot, newer ones (and the more expensive ones) have Gen 4 (which is twice as fast as 3 but in all honesty you don't need it unless you do heavy work on your PC like editing or gaming).
Quick and informative, oh my gawsh, thanks!
Thank you. I know what I'm looking at now.
There are some 2-lane nvme drives ("PCI-e X2") that have two notches just like SATA so you can't always tell what it is just by looking at the notches.
Finally 🥰 A video with the facts, Two versus One slot narrows it down in 3 words. Thanks
GREAT VIDEO. MY DOUBT WAS CLEARED.
Informative video on the basics.
well that cleared that up for me , nice n simple . thanks
Best explanation and difference on those ssd.
Great explanation!
Thanks!
Great video. The pin-slot connector really through me off once when I bought an adapter that could only do SATA M.2.
threw*
Great video. A little addition to your explanation : The 2 Notch Sata M.2 use's what's called the B-Key. The 1 notch PCIE [ NVME ) m.2 use's the M-Key. The M.2 socket's on the devices motherboard can be ; A B-key socket , A M-key socket or a combined socket that you can use either type of M.2 in that single socket.
Thanks for your comment, and we have more information like this available here: kings.tn/3Io874P
Great presentation! Although, I still don't understand what my Asus Z170M-plus board mean by "M.2 X4" and "M.2 Socket 3", which you did mention in your presentation at 1:57. The manual states that the M.2 slot is an "M-key". Wikipedia says that M.2 SATA is an "M & B Key". Now, I know my board is old (PCIe x3) and it's very easy to get an M-key NVMe PCIe x3 SSD, but the mystery to me is...... Will the NVMe work on my mobo with the mysterious "M.2 X4 Socket 3" information?
Nice video, I am still unsure though, I have a sata m.2 ssd (Sandisk SSD X400 M.2 2280) that is 6-pin (2 notches) would an enclosure that supports both m&b 6 pin PCIE and M-key PCIE work for it even if the drive is not PCIE or i need to get an enclosure that is not for pcie? I am asking because if PCIE supports it i would rather get that as i may use it again for another drive that is PCIE in the future.
Well explained! Thank you for the clarity!
Sitting here with a Macbook Pro from 2011, i'm talking about the ones with CD Drives and Hard Drives for storage. Thinking of a day when i can finally upgrade and be productive again without so much lag and incompatibility with everything. Sigh
I had found M. 2 back in 2015 when I purchased Asus Rog laptop.
But that time it was only sata.
So I bought sata m. 2 & it is still working like a charm
My 1TB Samsung SATA SSD can still boot my PC in 10-12 seconds, compared to the 2-4 minutes it takes a 5400rpm HDD to finish booting and readying programs to use. If you're using M.2, you wanna make sure you have a PCIe connection, as SATA is limited to 600mb/sec.
When I got my motherboard (Asus Prime B350 Plus) I almost threw out the little screw. Hopefully I did in fact save it. I have not evolved out of my 2 SATA hard discs yet. One used to give me errors, but I moved it to a cpu SATA port and it stopped. Apparently those you can only have the m2 in or the drive, not both.
Something I have noticed with alot of sata ssd's is after some games have finished a loading screen the screen will be almost completely white for a split second then the colors revert back to normal a second later. I have never known a pcie ssd to do this.
Very clear concise explanation. And very cute you! Thank you.
Great video. Building a new computer after 10 years (current one is still fine, but trying to get ahead of expected end of life limits of hardware). Coming from a "SSDs should only be for the OS" mentality, so very helpful.
Well, for gaming too, especially in raid, but expand memory to like 32GB if you have 16GB, and use a virtual memory drive to create a 'storage' for the virtual memory, that way, the OS can support virtual memory, which is to me pretty much obsolete, and yet required for most games or apps, while only using 16Gb of the ram for that.
Yes, sounds non-logical, but virtual memory is still a widely used function, upon non present games and apps may either quit or run badly, exiting to desktop "memory full" message.
(It makes no sense, that with 32 GB you'd get a message memory full, or simply app quit, and yet it happens.)
(It's better to have 16GB memory and 16GB virtual, than 32 GB real with no virtual, which makes no sense.)
(also, instead of using SSD as virtual memory, using the virtual drive (in memory) as virtual memory saves a whole bunch of SSD life, while still allowing for near maximum performance, but is less prone to SSD degradation by virtual memory.) It also prevents the OS from using up all the memory for 'better' performance, while the slow release usually kills the game.
Thank you it’s been a big help
So even though, I am familiar with some of the facts, I didn't know about the two notches for the SATA M.2 drives, so kudos for teaching me something new!
I am using three KC3000 1TB drives as a RAID0 device on both my computers. At peak levels, those drives reach up to 22.000MB/s read and 17.000MB/s write speed. If I had a bigger budget, I would have chosen the RENEGADE drives instead.
Before I forget, can you please bring back OPAL 2.0 encryption for the KC3000 series of drives please?
thank you still learning
Excelente la información, precisa y detallada.
Hey, she was from sourcefednerd. She and Meg Turney were so awesome on sourcefednerd.
I wonder what Meg is doing now?
This clears up alot of confusion
Just to confuse matters, there are also NVMe drives with both B Key and M Key (Two notches), but they use two PCIe lanes and not four. 🤷♂
The infamous BM
I have the same 2,5' SSD, and it's very cool for my PC, and me.
Thank you for the clarification. I really had no idea. Very informative and concise!
THANK YOU!
Thank you very much!
Great content but 4 years too late. Those PCIe blades (AHCI) have been outstanding, but you can not get them any more. Samsung 951 and the predecessor 941 hypetrain left the station in 2017.
danke danke !!! excellent info for those beginners !!!
my old wd blue sn520 512GB NVMe drive had two notches (also known as ngff form factor). And it worked with my old Asrock Fatality 990fx Killer Motherboard.
If I buy this new m2 memory and have a decade old motherboard with pcie slot, will it work in there?
Excellent video. Clear and consise.
Q. I have a 2TB SSD PCIe drive. Should I create 1 partition? 1+1 TB.
Any benefits on doing so?
Thank you!
M.2, 2.5" = type of form factor
PCIe, SATA = type of bus connector (i.e. speed)
NVME, AHCI = Protocols (i.e. bandwidth)
SATA, regardless of form factor, uses the AHCI protocols. PCIe uses the NVME protocols.
Thank you!
One question I had that I don't think was discussed was whether there is a difference between M.2 NVMe (which I guess is the same as PCIe? not sure) on a motherboard vs. M.2 NVMe on a PCIe expansion slot via an adapter card and if there are any issues like what kind of slot the adapter card is in or any other specs re: the card itself. I just bought an old computer with an M.2 slot but found out it's only for a PCI adapter assembly (Lenovo M900 tower computer) so I'm getting an M.2 adapter card for PCI Express card slot (physical link width x16; negotiable link width x4, x1) so I can use an M.2 NVMe SSD. The card is supposed to fit in PCIe X4 or X8 or X16 slots.
Hello there the NVMe SSD is the Bus interface while the PCIe would be the physical/logical interface. If you are going to use an adapter make sure you check the specifications of the manufacture to make sure it can accommodate an M.2 NVMe 2280 SSD. Also we found a posting pertaining to using an NVMe SSD and adapter on your system: kings.tn/3KP5eLq
And i have a seagate barracuda 1tb hdd (yes it has platters in it lol) that works amazing today along side my crucial ssd.
Which should i install ssd for 3×1 Lane??
I have a question, I like to upgrade my laptop Macbook Air 2012. So I buy the Samsung SSD 980 NVme M.2 SSD. Also buy a adaptor for this upgrade. After done everything when I do power on nothing happened. So I replace with HD comes with laptop and it's work right away. So what I do wrong? Please advice. Thanks.
I come for the info, stay for the eyecandy!
Thanks for sharing.
Very clear and helpful video. I have a rather strange question, hope it makes sense. I have a 7 year old desktop with a 2TB HDD. I am thinking about upgrading to an all new desktop, but not immediately. Could I transfer the 2TB HDD to an M.2 NVMe and use in the old system (at reduced performance of course) with an adaptor, and then move to the new system once I purchase / build it?
Thank you.
Just put 2tb in the new computer , 2tb nvme are expensive , back it up first
There are external USB adapters that are easy to use.
Hello Bruce, if you are trying to upgrade your HDD to an SSD you can essentially clone your old drive to your new one. Granted the actual used space on your current HDD will not surpass the capacity or your new one. For example your 2TB HDD only has about ~700GB of actual storage used, and your new SSD is 1.92TB you should be ok. If you have further questions please feel free to reach out to us here: kings.tn/3AyDqY4
I have PCIe M.2 in two of muh rigs, and a SATA SSD in muh main rig. All access your operating system (Windows or Linux) faster than mechanical drives, run programs very fast, and fetch files super fast.
Just beautiful

Does Kingston Technologies @kingston sell a PCI-ex1 to PCIe M.2 or PCI-ex16 to PCIe M.2 adapter?
My computer is old and did not come with either a SATA M.2 SSD or PCIe M.2, but I would still like to upgrade to get some more speed affordably out of my old desktop.
Hello Justin,
We do not sell any PCIe M.2 adapters.
wow. video is legitimately informative. nice
That was the goal! Glad to hear you found it useful 😊
What camera are you using to film this? The quality is amazing!
It's the encoding of 4K @ 2160p that shows the quality.
while we talk about performances for gaming always wil be in option to chose the better one who are in domain with speed so even if is not easy affordable ppl always at most gamer will patiently collect money for the best option for any component even if that is related to the disk.
Connection matters for quality products. Might as well take advantage of the faster connection of PCIe
In practice on a typical PC the speed difference between SATA and NVMe doesn't tend to be very noticeable, at least to me, and only a few specialist applications, like heavyweight video editing might perform significantly better. However, for a desktop I would go for the NVMe option anyway as the use of a SATA m.2 card generally steals one of the SATA interfaces.
It's an order of magnitude faster than sata in games that constantly stream in assets as you play (on a slow drive, the game will have micro freezes minutes after the level is loaded while you play). Their best use case are in these games.
How about NGFF m2 or Micro M2
I've read many of these fast NVMe M.2 SSDs' self limit themselves on speed based on temperature - they overheat unless you add an internal cooling fan ?
In most cases cheap thin cooling sink does the job. But almost all mainboards have already one pre-installed.
I was that guy sweating bullets. Guess, if you want the scoop on memory the Kingston memory experts are your guide. Excellent summary! Just wish you'd also discussed real world differences. I have a 2019 Dell 5060 desktop with only a long-in-tooth a HDD. It has an M.2 PCI 3 x4 and a couple SATA ports. In reality, how much faster would a M.2 PCI.3 x4 be over a SATA SSD for typical consumer/business use?
Thank you for the compliment! As for the difference The PCIe interface is generally faster, as the SATA 3.0 spec is limited to ~600MB/s maximum speed, while Gen 3 x4 lanes of up to 4000MB/s (depending on the host device). For more information please consult us via our Tech Support page: kings.tn/3DakQWz
Thisssss
This is the explanation I wanted
Man I'm hungry for a berger all of a sudden
I took my card out and it has the 2 notches as shown in your video. Does that mean my driver will not accept the one notch card (PCIe) ?
I just checked my laptop's specs and for hard drive it says: PCIe NVMe M.2 SSD Form Factor 2280. So now I'm really confused because it has 2 notches!
The B+M keys on an M.2 SSD allow for cross-compatibility on various motherboards if the appropriate SSDs protocol is supported (SATA or PCIe). For more information refer back to your motherboard manufacturer's website.
= a warp drive?
will i notice the difference with games if i buy pcie m2 vs sata m2? ty for this video!!
Yes the PCIe interface is faster, as the SATA 3.0 spec is limited to ~600MB/s maximum speed, while PCIe Gen 3 x4 lanes of up to 4000MB/s and Gen 4 x4 lanes up to 8GB/s . For more info please visit our site here: kings.tn/3M8H1kO
I think the only place I've seen an M.2 SATA slot is in a slighty older laptop. Too old and it would only support a 2.5 inch SSD, newer may finally have PCIe/NVMe capability.
Don't think I've ever seen a desktop motherboard with M.2 SATA, but I wouldn't put it past certain vendors to shave a few pennies off.
I have a gigabyte mobo that supports Sata m.2 - use it for mining with hiveos, I also have a USB enclosure for reformatting the sata m.2 drive
2021 modern of asus and msi, Acer still have M.2 SATA
There are tons of mobos that support M.2 SATA especially in the low and mid range mainboard chipset series... Mid range series boards also support both SATA and NVMe, so look more closely, please.
I have a fairly recent MSI motherboard that has one pci m.2 and one sata m.2.
Once I installed an Envy ME card, things sped up significantly.
Excellent explanation of a very confusing topic. Thank you.
do you have some external slots or readers for M.2 SSD PCIe?
Thank you for your inquiry. At the current moment we do not manufacturer any M.2 SSD adapters. For our most recent product lineup, please visit our website here: kings.tn/3J6nUX7
i have an extra m.2 slot in my mini pc, if i want to use a 2.5 ssd what adapter should i use?
We don't test adapters for compatibility, however you can search online for a M.2 to SATA connector with good ratings and try it out on your system.
We almost bought wrong ssd for our laptop. Thanks for this
i bought a crucial m.2 pcie and cant get it to activate or format but the disk manager sees it but fails to activate…need some setting?
Hi Geo if you verified the drive already and are having issues with it, we suggest you reach out to the manufacturer's support team for further assistance on this.
I need heat comparision between m2 ssd and nvme ssd please sir / mam

Wow! Trisha really is perfect for videos like these!
No she's not, her voice is the most annoying grating sound on Earth.
@@twoshedsjackson6478 Huh. I kinda enjoy her voice! But I guess I could be a bit biased since I've come to associate it with content I enjoy over the years...
Gaming: NVMe M.2 - lays flat on the board.
Some will be located on the back of the main board (motherboard) some will be located on the front.
To simplify - it's all about moving information quickly from point a to point b.
Think of it as a highway - more lanes fit more information - where will you notice it most?
Gaming - high amounts of data transfer.
When there's a lot going on, you need fast read and write times, which equals speed and efficiency.
Hope this helps explain the process a bit.
WOW, I had no idea it was getting soooo complicated.
I figured platters were slowest followed by SSd Tehn all NvME/M2 were the fastest but now there 4 generations of nvme/M2?
So which version/generation is my samsung 960 Evo?
its running in a B450 tomohawk mobo running ryzen5 2600 cpu
SOOO do i need the new AMD AM5 mobos to run fastest generation of nvme?
i need a new video card soon anyways and am trying to decide if i shud just upgrade current system with new Gpu/nvme hdd and possible faster cpu and memory
OR build entire new AMD Am5 system
Your current ssd is NVMe 3.0, as is your mobo. You would indeed need a new mobo to use NVMe 4.0 drives, but there's really no need for you to upgrade specifically for that, as very few applications are optimized for the speeds of even 3.0 drives yet 👍
If I were you, I'd just slap a better cpu and gpu in there and call it a day, maximum performance gains for your money. AM5 is very costly to upgrade to rn due to mobo and DDR5 pricing.
I have an HP x2 pro 620 G2...it has a pcie NVME (1 key slot) 500GB drive will it accept a 1TB or 2TB upgrade? manual only has 500GB but it is old.
Hi there, we were not able to locate the '620' but we do have options for the 'HP Pro x2 612 G2' here: kings.tn/3PD66G8

It took me a while before i realised these arent her arms anymore.😅 1:06
yea i thought my m.2 nvme was a bit chewy today, does it come in spearmint?
There actually are some NVMe M.2 drives that have two notches like the SATA M.2 drives commonly do; they're rare, but do exist.
What are these for?
the thing is is that its hard to find motherboard with the 5 so i can reach my true potential of my t700 crucial 4tb 12k read drive
Hi sister, I got hp15-da0030ni, i5-8250u notebook laptop. I'm asking which one is compatible SSD or NVMe to replace HDD on my notebook and improve speed?
Hello and thank you for your inquiry. You can visit our site here to check out the available SSD upgrades for your model here: kings.tn/48Y126N
I've got a slot for an M.2 2242 SATA SSD (B Key) and a slot for a 2.5" SATA SSD, which of these drives is faster, and which one could be recommended to install Windows on? (PS: I want to install Windows on the faster one)
Thank you for your consideration on your next upgrade. Now since we only offer M.2 2280 NVMe drives for post-purchase options, your best bet would be our KC600 2.5" SATA drive for your current model. Please visit our site here for ore info: kings.tn/3w2LCQb
@@kingston Thanks, but why the KC600 though? Why not the A400 or Q500
Since you were asking about which drive is faster and the M.2 2242 NVMe was not an option, for SATA drives, the KC600 offers slightly better baseline performance compared to the A400 or Q500. If you have further questions, please visit our site here and chat with our Tech Support: kings.tn/3we3rfq
Thank you
Have you ever rated what SATA M.2 SSD (2 notch) memory is the fastest and all-around best. I can't find really anything about it.
Let's start by saying that in December 2022 we shipped out the last of our SATA M.2 SSDs, the A400 M.2. We no longer make SATA based M.2 SSDs and going forward all our M.2 SSDs are NVMe. But at the time, SATA M.2 SSDs used the SATA interface with a maximum data transfer rate of 6Gbps. If you want to check it out, visit our site here: kings.tn/4bAOjJ1
Is this Trisha from SourceFed ?
so if I have nvme m2, I can't use my graphic card if I have only one PCIE?
Hi there if your computer only has one PCIE connector check to see if it has a dedicated M.2 NVMe port for an SSD, then you could be able to add your graphics card and SSD without an M.2 Adapter for PCIE. If you have more questions, please visit our Support Page: kings.tn/3LrQYsi
