- Samsung has announced a new flash storage solution for smartphones based on the UFS 4.0 specification. It is faster, more power efficient, and ever so slightly smaller. Here is my overview of UFS and a quick look at the advantages of UFS 4.0.

Differential signaling for high speed logic has been around since about 1962 (MECL). At that point in time it ran off negative voltages and used huge currents. When I say huge I mean that for example the -5V power supplies for Prime computers rack were 200A and the ECL racks had up to 4 of them and the same again for the -2.2V PSU's. The main reason for ECL being faster is that the driver transistors never go into saturation. The second reason is that for a given track capacitance if your voltage swing is less then there is less current needed to change level. The other advantage is being differential. That conveys a lot of noise immunity and also allows for transmission line theory to be applied. In the 1980's ECL started being used in a PECL (Positive ECL) configuration. It was the same 10K and 100K series parts. Fairchild made the 100K series which was similar to the 10K series except it was temperature compensated. They also took propagation delays from 2ns to around 0.75 for most simple logic. Remember this was in the early 1970's. By the 90's ECLINPS was around. By the late 90's ECLIPS had D types capable of toggling at 3GHz and was optimised for positive voltages and lower voltages (down to 2.5V single supply). It is this logic that for example PCIe channels use in processors except better lithography and smaller line widths on the chips IE we were at about 250nm in 1996 and by 2012 that had reduced by a factor of 10.
Is speedtest G channel not a thing anymore? I am still waiting for an exynos 2200 vs snapdragon 8 gen 1 vs mediatek dimensity speed test G and stress test G. I guess you had trouble to get 2 s22 ultra and the k50 :(
All you need to know is China has a backdoor into the media tek ☹️. USA has a backdoor into the Snapdragon. ☹️
same here, i always excited for speedtest g
@UA-cam Sans im talking about speedtest g brother
I love that tech is getting better and better. I hope we see UFS 3.0 in cheaper devices later on too. Better tech making its way down, that's beautiful.
From what I can see, there are still budget phones today shipping with eMMC or UFS 2.0
So I don't UFS 3.0 is gonna trickle down any time soon
The Poco X3 Pro came out like a year ago for $300 and it had UFS 3.1 (Also Snpd 860)
@@MsMonster128 that's an exception and 300$ is nowhere near the cheapest phones. Plus even if you get 860 SoC and ufs 3, it's a budget Xiaomi so you'll get screwed elsewhere (materials/screen/build quality/OS)
@@YounesLayachi Just stfu dude, in this market $300 dlls (now is actually $250) IS cheap for an 860/6gbs of ram/120hz/UFS 3.1 and 128gbs of storage
@@YounesLayachi Myself used the device and material is good, screen ain't AMOLED but it hardly matters until you consume a lot of media on the device and have a better screen as the bar for yourself, and the OS, you can always customize the ROM, so I don't see what's your point.
Currently using UFS 3.0 , upgraded from emmc 5.1 last year.
Difference is huge.
The storage have great improvement, but it's hard to separate the benefits of storage from the soc performance. The diferente is result of both improvements
I used ufs devices for so long,
Now emmc devices are just painful to use...
@DANIEL CHUKWUKERE at first I didn't know it was the storage that made the difference.
I got OnePlus 6T, my first and only flagship device, and I enjoyed how fast it was. I thought the flagships specs were making the difference.
Until it got stolen.
Then I got a cheaper samsung phone, less than half the price of OP6t, but it was still just as fast.
Digged up the specs and turns out it's the UFS storage.
3 years later I'm still rocking the same phone, and it's awesome...
@@MacgyverFreitas yup,you are right ,i upgraded from mediatek helio p60 to Exynos 9825.
@@phs125 yup
What a great bit of engineering! And great explanations from Mr. Sims.
Technology in Smartphones has developed rapidly. Recently discovered technology
1. UFS + SSD Raid 0
2. LPDDR5X
3. UFS 4.0
Year 2023 Smartphone Flagship will be so fast especially on Android
Maybe in 2024 we get Snapdragon flagship soc's with Nuvia designed custom cores.
wifi 7 and Bluetooth 5.3 and ltpo 3.0 amoled display
Yeah, but the 46% efficiency actually a big fat lie. They are measure that in read speed per mA, but the read speed is 3x compared to UFS 3.0, so the actual efficiency is 46% of the 300% power consumption, that use 138% power compared to the previous version, so it will use +38% more power if you use it on max performance.
@@Winkoo6 It depends on what your benchmark is.
If you want to read a fixed amount of data for your benchmark, then mA/read Speed is perfectly fine, because although it will consume 3x more power it will also be finished 3x faster and thus it cancels out and what remains is the 46% efficiency gain.
@@the_real_glabnurb but you also need to calculate the CPU side power consumption too, because UFS still use the SATA, and after 3.0 they are adding the RAID for those drives. 5 drives for UFS 3.0, probably it will 10 or even more for UFS 4.0, each added drive increase the CPU load a bit for the software RAID, so in total you lose more performance from your phone, and also lose more power just because of that too. And this more power consumption will be not showed in the efficiency, they will only show you the used power of the storage there. Also if they are already behind in CPU performance, not too clever to sacrifice even more performance on the storage.
Samsung is a major player in terms of storage along with other major technologies
Great. Always amusing to see where this is compared with the 8mb memory card my mum probably still has in the garage, or the mp3 player that transferred via a parallel cable!
I think upcoming UFS tech will be used in the future samsung laptops as they will match the SSD speeds for the power they consume.
Great explanation as always!!
Sir can you throw some light on whst storage and ram solutions does iphones use because that info isn't available easily.
Same for M1 series integrated ram and storage hardware
That would be great, but I think Apple has some proprietary implementation there... Maybe some of it is undocumented as today
It uses NVme SSDs
That's an insane speed from one single package!
Great content
Sir, can you explain a modern computer architecture?, how cpu place how pcb designed , how ddr connected north bridge etc..
Hey gary will you test he mediatek dimensity 9000?
So, it's like the CAN BUS in automotive applications, correct?
Which External storge is better that would be Future proof with UFS 4.0
Segate FireCuda or Sandisk Gdrive Pro ❓️
Very interesting.
Can it match the iphones nvme storage speed
what's the relation between ufs and nvme?
are they competing standards? or you could you possibly have and ufs flash chip on an nvme ssd?
i'm mostly thinking in light of the m1 mac studio moving the ssd controller into the m1 chip itself
It would be nice if Gary made video explaining it but so far I have managed to figure out the controller is different, UFS using SCSI where NVMe used specific controller only used to manage NAND flash. The main focus of NVMe is speed where UFS also got focus on power consumption. They both use NAND flash and full duplex (so they can both read and write). Regular NVMe is build to be plugged into a PCIe slot but Apple has custom controller.
@@AndersHass well technically apple's controller is inside the M1 SoC but uh UFS uses SCSI as the controller? wat? really? 👀
the way i see it, if the industry moves on to SoCs (so as with the new UCIe standard) and if the controller is in the SoC and uh also standardized we'll be swapping NAND flash at some point xD
nvme on iphone or ufs 4.0 is better or faster?
Papa Gary is the best 👍
I have the K50 Gaming Edition and a Red Magic Device... I can tell you that I have UFS 3.1 and IO Turbo combined with LPDDR5 Ram... I can tell you something... Already it's on par or even overtakes the iPhone 13 pro max... It is one almighty gaming phone. And that is something. Especially as a red magic user... I totally recommend any black shark or k50 gaming edition totally... I did actually order the Lenovo Legion Y90 with SSD Raid 0. But the seller canceled the order due to not realizing how cheap they where selling it.
it is hard to look at smoothed backgraund
I have two questions that I need help with; firstly if the differential signal is two wires of .2V and -.2V (for example) what stands in the way of just having a single wire at .4V instead? Secondly, the diagram at 3:30 shows that interference is cancelled out by using a differential signal but what prevents the interference from constructively interfering and doubling the total interference instead of cancelling itself out?
Single wire interfaces are more prone to noise. There are lots of systems that work on a single wire, but for noise reduction (which equate to speed) differential signaling is better. The idea is that a blip of +0.1 volts will appears on both wires and therefore the "difference" remains the same.
I always wondered, why they don't use pcie protocol for storage in smartphones? 🤔
How it compares to ssd speed read and wrote speed?
Why is the image blurry on the background 😅...
FYI samsung also pioneered flash-friendly file system (F2FS) and made it open source
Garry i heard of SFS 1.0 storages used by huawei, which one is better?
Can you make comparison between Nvme, ufs4.0,sfs1.0(if its true)
Huawei's SFS is a cloud storage service, not a smartphone storage solution.
@@GaryExplains 💀 no wonder I was weirded out by this comment
When will you return to speed test g channel ?
What happened to speed test g 😭 please bring it back
Nice one from Samsung. Smartphone storage is about to get even bigger.
Is there a mobile media interface upcoming which can replace SD cards?
Internal is way faster than SD card.
That chip graphic looks funny to me with all that real estate around the BGA land pattern. I wonder why they didn't space groups of balls out to make PCB fanout a little easier without having to get a high-spec PCB fab involved.
will UFS come on galaxy fold/flip 4 and upcoming phones?
No. It won't be ready until 2023. SOCs have to be configured for it and I think Snapdragon 8 Gen1 only supports up to UFS 3.1. So unless Qualcomm, Samsung or Mediatek update their flagship 2022 SOCs, the Galaxy S23 will probably be the first phone to use it
FYI. Differential signaling doesn't help with "bit jitter" issues.
Very cool. But I still want a micro sd card. I would even settle for hauwai solution of a proprietary removable storage if it needs to be smaller in size to fit.
😂
Another improvement to another industry standard, the way it should be, but hardly a major tech. leap... I'm waiting for one or more of the cutting edge non-volatile RAM solutions to become cost-competitive. With more fabs going more 3D we should soon have cheaper, far faster, more robust non-volatile SRAM and DRAM replacements that could kill off flash drives (except maybe for removable (backup) storage where speed is not important).
--
IBM's spin-tronics are becoming commercially viable, as are less exotic, non-flash based non-volatile RAM. Flash stacked onto DRAM will continue to develop too but will be made redundant by more exotic solutions... Non-volatile Photonic SRAM / photon-induced spin-tronic SRAM (by SRAM here I mean any memory that is not dynamically refreshed, so low power consumption)..
Wasn't that long ago they created special web pages for mobile devices which I have not seen for sometime. These devices are now in some case more powerful; than desk top computers.
They still do. The processing power of the computer crunching the web page data isn't the only reason for mobile friendly web pages. It's also the screen size issue, both for readability and having finger-mashing sized interface widgets.
What happened with the speed test g channel? 😱
Phonebuff speed test is all you need. Speed test g has lost its way.
Phonebuff speed test is all you need, LOL 😆😆😆 I guess you didn't see my video on why traditional speed tests are fundamentally flawed.
@@GaryExplains It was a joke to get you to say something. No worries man, lol.
So finally 1tb variant smartphones won't be made in tiny quantities and website exclusives...
Yes. Finally you will be able to store multiple 8K hour long videos For Academic Porpose
@@Hiddenus1 Yes, for academic purposes.. lol
a raspberry pi 5 with UFS 4.0 would be sweet.
Raspberry pi with an octa-core SoC, neural accelerator and a high-performance GPU would be excellent
@Ajinkya Mahajan That sounds like an NVIDIA Jetson!
samsung have been king of flash storage
Unrelated, but how do Smartphone SOC's compare to the Switch
If I'm not mistaken, the switch is just a modified soc of an Nvidia shield. So at this point an 8 year old or so arm architecture made by Nvidia. I think the soc is called tegra X1
@@GrymShip Yup
@@filleswe91 The latest iteration (Tegra X1+)
Scores:
~113K antutu 6
3,900 multi core
1,400 single core
Geekbench 4
1000 multicore
290 single core
Geekbench 5
~3900 slingshot extreme 3d mark
Does pretty well here as these numbers are beyond the 660 for this test. About 768G levels.
I would say the CPU component is a tad slower than a Snapdragon 660. GPU seems to be a tiny bit better also. These numbers would probably be only achievable in docked mode for the switch however.
It's between the performance of the Snapdragon 480+ 5g and the MediaTek Dimensity 720 5G in performance. Neither of those is particularly fast.
I wanted to watch this, but that blurry background drove me off. My eyes kept trying to focus on it and it became rather annoying to look at. Not sure if anyone else had the same issue.
Hey Gary,
How to do you compare UFS 4.0 with NVME?
Thanks.
@Corporeal Undead By UFS filesystem do you mean F2FS?
If it's, is not a UFS filesystem, but a filesystem for any kind of flash memory
Should be out when I decide to update my current 2.5 year phone.
S23 has this now
that's a very weird blur you chose
normal gaussian would be cooler
I am glad you are concentrating on the important things. 🤦♂️
@@GaryExplains lol 😂
well, it is 75% of the background in 90% of the video
quite important i think
feels like i'm cross-eyed all the time
I give up 🤷♂️
@@GaryExplains ocd kicks in 😂
UFS means Ultra Flash Storage!
From Mobile phone storage speed and reliability, do we still have the reference: emmc=>UFS=>NVMe? From what I know, NVMe SSD in a PC is one of the fastest storage available, much faster than S-ATA.
Me too, some things need a bit more simplification for people not as involved with tech. Linus had a video clip talking about USB and HDMI specs. It's a bit daunting, let alone confusing.
@Daniel Vipin not the same tech used in actual PCs
it's not as simple as that there are many types of nvme storage just like ufs but way more complicated sigh(ᇂ∀ᇂ )
@Daniel Vipin I don't think it's that simple buddy 💀
@Daniel Vipin bruh I can say that about the lg v60 which is a 3 yearold phone or maybe 4 IDK it's still faster than the Galaxy s22 at rendering in certain apps.. same with the Galaxy note 9 and the Galaxy s10+.. I told you it's complicated I don't think you can call either faster and if you can you need to specify at what
Flash pim?
And Apple will order this and advertise it into their keynote
Just knowing between UFS 4.0 and Apple's Nvme which is faster and more efficient?
🙏🏽
At this moment the UFS 4.0 can beat the NVME in phones, but NVME is more efficient, and also they can upgrade that limitless, it's actually the same technology like you have in your PC, M.2 SSD also an NVME storage what connecting with PCIe, you can see on those drives what can the phones reach in a few years. But UFS 4.0 will use even more power like the 3.0 (just read the efficiency part, they measure that in read speed per mA, but the read speed also tripled, so 46% of the 300% power consumption is still 138%, it will use +38% power compared to the UFS 3.0). Also they can make excuse and not gives you updates just because you don't have a UFS 4.0 device etc..
It beats iphones nvme speeds in sequential write/read. Just like ufs 3.1 already did. However unless you always move around very large files, sequential read/write doesnt matter a lot. Random read/write speeds matter a lot more. Those and latency is where nvme excells.
@@manulovesjesus Sure but the main purpose of high capacity storage alternatives is exactly big files management.. 4K videos might be the best example.
Is ufs 4.0 the best?
The best for what? Performance? Power efficiency? Density? Cost?
@@GaryExplains overall compared to nvme on iPhones
All hail SCSI!
I might still have a SCSI scanner somewhere in storage... Not that I use it anymore since my ethernet connected multi-function printer has a scanner in it...
Nvme vs ufs 4
Yeah but what we really need is for them to incorporate any of the UFS tech properly into their devices.
I have a Note20 and the Read/Write from the Internal and External memory is still SLOWWWWWWWWWW.
It is faster for me to remove the external memory and directly connect it to a computer to pull the data off instead.
You understand that the external memory card doesn't use UFS.
@@GaryExplains Then they need to tell all the Micro SD manufactures that.
@@RGressick The SD card standard is defined by the SD Association. It is very separate to UFS with its own protocols, buses, and performance levels.
@@RGressick basically think of UFS as a solid state drive and SD as a Hard Drive. SSD wins every time lol.
Solaris switched from UFS to ZFS over a decade ago, Samsung needs to get with the times
LOL 🤣🤣🤣
Ufs like undertale final showdown
May 2022... and I still haven't seen anybody test if aerogel can supercool GPUs.
Aerogel is insulator
@@zabique 😂
@@zabique
en.wikipedia.org/wiki/Aerogel
Aerogels are good thermal insulators because they almost >>> nullify > heat transfer > convective inhibitors because air cannot circulate through the lattice
@@zabique ua-cam.com/video/qnOoDE9rj6/v-deo.html
The heat sensor camera after the flame thrower went showed that the heat is... still... inside the aerogel. Listen very carefully to the video explanation... in that the pores of the sponge-like structure are so tiny that hot air... struggles... to diffuse... through... them -- therefore, absorption. There is just enough room for usually one oxygen molecule inside each pore... and because there is no friction within... the heated oxygen will just rapidly bounce around... inside... the aerogel as seen from the heat sensor. Granted... if far more heat than a GPU can radiate, it is then that the... excess heat... will get deflected. The heat is just vibrations of molecules... not the molecule themselves which means the heat can be further added as vibration into the... trapped... oxygen molecules... which again is another part of the absorption.
@@zabique That's exactly the point of why it would be perfect for GPUs.
Why android smartphones don't simply use PCI like other devices?
Like what other devices?
PCI is just a bus interface. You can use UFS/NVME in conjunction with PCI.
Im still stuck on emmc storage because peasant
Even UFS 3.1 still not a mainstream yet UFS 4.0 has been out
Well obviously. Leading edge tech isn't for the mainstream. However now that 4.0 is out then 3.0 and 3 1 can move into the mainstream.
android market seems to be stuck with 64gb storage since the past 5-8 years
Well that clearly isn't true.
Yeah, for $100 androids
Ahhhhhh...Samsung...they seldom dissapoint...unlike sandisk!
Apple will probably charge 10k dollars for 8TB…
qled, ufs, ultra-super-duper.. So typical for Samsung.. I didn't get why this thing is appealing, despite this vid was in my newsfeed for already 6 days undismisable.
qled? I don't see the connection.
@@GaryExplains For me a connection is pretty simple: Samsung gives loud names to small technical improvements. And for me this is hard to explain, considering huge market share because of real technical advantage of Samsung's products. They make a lot of chips/products that do not need additional marketing department efforts.
Hmmm... But Samsung didn't invent UFS, it is a standard by JEDEC. This video is about a solution from Samsung that follows that standard. It has been around for years and is used in millions of smartphones from Samsung and many other brands. This video is about the latest iteration, UFS 4.0.
@@sc0or How is modulation of light wavelenght at subatomic level a small technical improvement?
@@absolutium I think this "modulation" is well knows since Cherenkov's emission was discovered. And all IC manufacturers consider all delays related to Ɛ.
I simply wouldn’t trust Samsung with anything storage related again with the way their device storage performance tanks when not new.
Every single storage method degrades with usage.. thats why you require twice the storage if you aim for longevity. Like CCTV systems.
It’s plummeting performance that seems to affect Samsung solid state though. I don’t recall problems with Samsung spinning media.
Hey Gary. Your background is giving me stroke.
