OWC Accelsior 4M2: Adding 4TB SSD Using a PCIe Slot on 2019 Mac Pro!
Вставка
- Опубліковано 2 січ 2020
- When the Mac Pro became available for purchase a few weeks ago, we bought a base model and have since been demonstrating upgrades with third-party components for those interested in boosting their Mac Pro's capabilities without having to shell out for Apple's upgrades.
We covered upgrading the RAM in a Mac Pro in our last video, and today, we're demonstrating how to add additional SSD storage using one of the Mac Pro's PCIe slots.

Thank you for this fantastic tipp - great SSD!!!
Actually this is a bit misleading. The real reason you saw faster transfer speeds when transferring the Folder from your internal drive to your PCIe drive is not because the PCIe drive is faster, its because the Read speeds of your internal drive are nearly 2x faster than the Write speeds as shown in your own internal Disk Speed test. The transfer speed will always be bottlenecked by whatever device is slower. (In this case the internal drive).
You failed to mention you have to take the cover off the side slot, under the thunderbolt/USB Ports. If that is not explained some viewers may try to force the 4m2 into the slot not knowing that out side cover needs to be removed.
many of these are great on the classic mac pro.
which can now actually use pcie based thunderbolt, usbc, nvme, current GPU, etc.
some will require hacks, but not most.
with the 12 core 3.33-3.46, not being that much slower than the 2019 mac pro base model.
I think it's pretty important to say that that SSD is actually 4 SSDs in Raid0, and if any of its SSDs fails there is no chance of recovering any data from the whole volume.
daschundwoof agreed. I also think SSD failure rate is lower, and these OWC flash drives are over-provisioned by 7%-giving even higher reliability and lowering the risk of failure. Always have a backup of any data even if you have a RAID with data redundancy, which is not true backup.
Yeah I agree. It seems like a worthy option for a person needing storage that is that fast.
true, but do you have to use it in raid?
Tigerex966 you can use it as four individual SSD drives (each is 25%) of the total capacity.
I'm probably getting one of these and it comes with softraid software. You can configure it as raid 5 so you get 75% capacity, raid 0 speeds, and 1 drive can fail without losing data.
Thanks for the video! 💯 🙌 - One question: For your newly installed drive, did it come with TRIM enabled automatically?
Hmm, i like this one better as opposed to what i've seen around already. This OWC one, at least hasn't a fan. So that makes it quiet !
How did you configure the OWC drive? RAID 0 or concatenated JBOD (lower performance)? Or did you just benchmark against one of the 1TB M.2 drives, which would lead to lower performance. Did you use SoftRAID, or create disk sets in Disk Utility? OWC SoftRAID currently requires you to disable secure boot in T2.
You left out one important step for install: after unscrewing the bracket, remove the slot cover.
Would love to see a usb 3 expander pcie card. Also how a Sonnet tempo dual ssd card goes in the new mac pro (perhaps with 2 owc ssd 6g extreme pro drives)
Slow.
Should the apps on the Mac Pro also go on the Apple ssd or would it make more sense to just have the os on it and add the apps to the OWC drive? Would apps like photoshop and capture one benefit from been on the 4m2?
Also, seems Sonnet option is faster ... thought it is sold out everywhere :(
Does the card run hot with those ssd’s installed?
If Windows is install onto the native Apple SSD using bootcamp, can this SSD be use in Windows as a regular hard drive?
Is the 256GB single drive that this model comes with, slower than a 4TB (BTO) drive? Or are they the same speed?
Trusteft 256GB config has a single SSD module installed whereas 1, 2, 4, and 8TB configurations have two modules. Apple’s 3.4GB/sec sequential read/write performance is based on a tested 4TB configuration. So...
When I boot up from external on my 2019 max pro tower 7,1 the internal Apple Mac hd is not on my desktop. I have all other drives showing. How do I fix?
I’d be curious if those SSDs are swappable, ie open it up and see them like the Sonnet option. If one of the 4 fails you have to swap it right? Does it work with other brands like a 970 EVO?
Yeah this. Seems important to be able to fix it if need be.
Lux Pro yes, you can remove the heatsink that is attached by screws and then swap out the M.2 NVMe SSD modules. OWC sells an Accelsior PCIe board with no SSD-add your own.
Hi can you do a video, with video editing i want to see how the 580x performs
THANKS :D
Can you boot from this SSD and not apples for faster start up?
Ah I'm looking for the same answer
@@Paulkatz123 I messaged them. You cannot.
But you can use it to keep all your files on and it will be faster
You can also upgrade your processor to 28 core!
I wont 2 cpus,less cores and more ghz.
But why on earth doesn’t Mac Pro 2019 provide pcie-4? It only has pcie-3. Feels old already, but maybe it was more acceptable in 2019. I still have old Mac Pro 5.1 (2012) and it starts to feel really slow and out of date.
There is a card made by squid that is way faster than what you chose.
Theres a bottleneck in your tests. If you get another OWC accelsior 4M2 and do the same test, but having one of the accelsior being the control, you should see much more significant and accurate results. Ie. OWC > OWC < OWC vs OWC > Internal < OWC.
Seems they increased the price on 8TB option to almost $2K
Petar Smilajkov yes, OWC increased their prices across all of their PCIe SSD cards within the last month. Maybe you can still find one at the lower price at one of their resellers like I did?
The Three Techs any hint? :)
Petar Smilajkov B&H had it at the lower price, but now it’s gone up. Here’s their full list of resellers:

Good luck!🍀
I can see you use slot 8 in this video at 03:28, why? I mean Slot 5 is fastest because of ×16 lanes, or Slot 6 or 7 ×8 lanes. You can get more speed another slot.
kazuhiro ishiyama good catch. Not sure if they changed slots before doing the tests, but slot 8 is only x4 lanes and would give suboptimal performance since the OWC card is x8 lanes. Slots 1 and 3 are directly connected to the CPU and will yield the highest performance.
which 3d program do you use to create your thumbnails?
Blender 🙂 www.blender.org/
Yo have to be hulk with the fingers of a little girl to release those screws without a screwdriver.
Amfeltec has a pcie raid card that will take 6 m.2 nvme drives and that is way much faster.
Yes. At $769.00 for the card only, plus shipping from Canada, plus a 4% fee to pay via credit card or $30 bank transfer fee to Canada. Too pricey!!!
@@algheroman6476.A really fast card for the rich.
@@gerald4027 I was ready to buy one until I got the quote. They also have a 4 - m.2 version for $386. But you still need to add shipping from Canada and fees for payment. A little ridiculous. Too rich for my blood with other alternatives out there.
@@algheroman6476.I will be in the Dallas-Fort worth area and will be checking a few computer superstores about cards.I will let you know in about 3 to 4 days.Have you tried sonnet,highpoint,syba,or asrock?
Is this bootable?
Know your audience.
Make it the main SSD see if it’s bootable.
It is bootable by dropping one drive out of the raid. 1 for OS 3 in raid 0, but what's the point just boot off a single NVMe.
I have the 2tb version of this card.
Not a good idea to have the heat sink so close to the top card.
uglypoe agreed. Apple recommends spacing your cards out for better cooling.
I was able to beat that with a 2009 Mac Pro five years ago. ua-cam.com/video/HrmNtd9_U0E/v-deo.html
And that’s using Apple’s single threaded AppleRAID driver. With SoftRAID (if you can get it to work with your system), it’s faster and stays fast over time. HOWEVER, be aware, keep the m.2 drives cool or they WILL slow down significantly during reads and writes. Glue a small heatsink, or control a fan that’s blowing air past it. Look into Amfeltech, a Canadian company that’s been building custom high end PCIe cards for Mac Pros for a long time. They are the real deal. Your welcome, btw.
Internal storage of 256GB is fine. It's _JUST_ for the OS. In a serious machine, there will always be serious data far beyond what "internal drive" could offer. I prefer a small (tiny) main boot disk and then add my own storage (internal or external) as I require.
not for everyone, it totally depends on your workflow.
Which is why so many people upgrade.
Yeah having that little storage does not work for me but to each their own
MacRumors In English “each” is singular, “their” is plural... To each his/her own.
@@cfazio Trademarks allow for that, which is why Apple often capitalizes the second letter in a word.
To each his /her own.
alliejr just realize that the 256GB config comes with only a single SSD module. 1-8TB configs come with two modules, and the Apple performance spec of 3.4GB/sec seq. read/write is based on a two-module 4TB config.
Highly misleading review. The read/write speeds of Apple upgrades are more like 3KMB/s. The 8TB upgrade clocks 3.5KMB/s reads. MacRumors is benchmarking against a single Apple 256Gb stick. Given that we are talking about upgrades, this is close to fraud.
This video is extremely misleading. This drive is running 4 SSDs in RAID 0. Please do research before posting these videos.
