When your upgrade goal is to make your machine as fast as possible with maximum reliability and cost effectiveness, the Accelsior 1M2 is the answer. It utilizes an open PCIe slot in your Mac Pro or PC to deliver the thrilling speed advantage of a NVMe PCIe SSD. It's plug-and-play ready to put you in the fast lane of pure uncompromised storage performance.

At the heart of Accelsior 1M2's power is an OWC Aura Ultra III PCIe 3.0 x4 SSD that's been engineered with fail-safes to increase longevity and preserve best consistent performance, especially in write-intensive workflows. From running double checks on data and correcting errors to ensuring the uniform use of its flash media, the Aura-based Accelsior 1M2 is a stable, dependable, and ultimately safer place to store your data.

When deadlines and workload pressures start to mount, the Accelsior 1M2 helps you keep your cool. An industrial quality black aluminum alloy heat sink with deeply grooved fins silently keeps the Accelsior 1M2 performing at its best so you can remain chill focused.

Non-Volatile Memory Express (NVMe) is a communication standard specifically built to optimize the performance of modern flash technology. It enables the Accelsior 1M2 to deliver significantly faster SSD performance vs an SSD using the SATA interface, a communication protocol that was originally designed for hard disk drives.

By supporting PCIe 4.0 and earlier motherboards and able to plug into x4/x8/x16 PCIe slots, the Accelsior 1M2 is a perfect performance drive upgrade for a wide variety of full-sized and small form factor computers. If your Mac/PC doesn't have an open or compatible PCIe slot but is Thunderbolt 3 compatible, the Accelsior 1M2 can be used externally in a PCIe Expansion chassis like the OWC Mercury Helios 3S (sold separately) at speeds up to 2800 MB/s.

Time is money and you can't risk depending on a cheap, no-name device that claims to work trouble-free. Before every Accelsior 1M2 ships, it undergoes a multi-step performance certification to ensure it arrives ready for demanding use with the Mac Pro 2019 as well as Mac Pro 2012/2010 machines and PC towers.

[ M.2 SSD ] Save Money and Build your own NVME SSD. Enclosure holds four NVME Used four 4TB NVME PCie 3.0 M.2 Internal SSD that create 16TB SSD in Raid 0. It works and it is fast. Great for processing and rendering 8K video to 8K and 4K and 1080 video projects. 5

[4 TB] Hands down, it is the fastest drive I have ever tested. I'll be upgrading all my external drives when they come back in stock. 5

James	26/08/2024
[ M.2 SSD ] The physical drive itself is great. I really like the SoftRAID software it comes with but it has two issues: You have to completely disable Apple's T2 chip security feature for SoftRAID to install its driver. I believe if they worked with Apple, Apple could sign the driver and allow it to be installed with the T2 chip setting allowing T2 security turned on with SoftRAID driver. A fix may be on the way for that. Second, the RAID drive does not show up on the About this Mac Storage status. Not a big deal. Otherwise SoftRAID is very easy to use, clear graphical user interface. It is what Apple's RAID setup should be. So far I have had no need to use it to rebuild/recover a RAIDed drive. Therefore I can give no feedback. This is being used on a 2019 Mac Pro. 5

[Low Profile] Decked the OWC 8M2 out with 8 Samsung 980 Pro SSDs for best case testing. Never got close to the expected throughput. Only 10K sequential on Crystal Benchmark. Card worked with Gigabyte AMD X570 motherboard but would not boot with MSI Intel 670X. Clearly OWC has compatibility issues. During the first overnight burn-in test, the card completely failed. No longer warm to the touch so must be power issue. Since B&H dropped ship from a 3rd party, I'm forced to wait until the 3rd party issues their own RMA. It's now been over a week and no sign of the RMA despite emails, chat, and phone calls. I'm running back to Amazon. 5

[Low Profile] mechanical drives are slow. I deal with large libraries and large files that are difficult to move around. This drive saves me so much time and makes my life so much more productive. You have to figure out a solid methodology first and follow a protocol. I do all my work off 2 SSD solutions and then at the end I move it to a mechanical drive (2 actually - one is main storage and the other is a mirror for those OHSHI moments). I use a script to move the items so life is carefree. I did run the speed test software and you get what they say. Just wish that I could get more than 8TB as an option. Somethings you regret buying. This isn't one of them. 5

Sebastian	21/07/2024
[ M.2 SSD ] Love it, just wished it would mount faster on the desktop. I have my dropbox in it and sometime when I reboot the computer DB can't find it(because it didn't mount yet) and causes some issues. So I turn on DB manually now. 5

[Low Profile] I use my unit to edit, I have installed in Mac Pro 2019 PCIe slot. Back Magic Speed test is 4800mb/s read and write. When I'm editing full 4K at full res no dropped frames, very speedy render speeds also in Premiere. A caveat, you have to change security settings in Mac's with T2 cards. They will prohibit raid 0 functions. But after a call to tech support and a few changes to the settings all is well. 5

Chad	09/06/2024
[Low Profile] So far so good. Purchased a new base model Mac Pro 2019 and installed this in a 16x PCIe 3.0 slot in a striped raid for speed. I get an average of 5000MB/sec read and write. Slight issues installing which required a call to OWC tech support. They were very helpful and it was a known issue. So expect to do that. Otherwise working well! 5

Scott	19/05/2024
[ M.2 SSD ] This is a 5 Star item but you need to read my review as I learned a few things about installing and using this. First, this is very, very easy to install in the older Mac Pro Towers and from what I have seen, even easier in the 2019 Mac Pro Tower. It literally plugs in and is good to go. BUT, there is software that comes with this card and the activation key is on a sticker on the card so you need to write it down or, like me, you will be disassembling your Mac to take a shot of the code. ALSO, this card DOES NOT support the APFS format which, in my case, is the format of my startup disk meaning that I was not able to use it as a startup. SO, it goes so much faster than my current 2010 Hackintosh Mac Pro can take advantage of BUT when I get my new 2019 Mac Pro, I will be able to simply take this out of my current Mac and insert it and use it in the new one where it will save lots of time and $$$. The SoftRAID software works very well once you use the provided activation code. One last thing. This card heats up which was surprising to me as I have several SSDs and they hardly get warm. So, I am taking the precaution and turning my computer off when I won't be using it for more than a few hours instead of simply putting it to sleep. One more last thing. I did get to work with OWC support and they were very easy to chat with, handled my problem quickly and I found out that there is no need to register the device as I believe your serial number or invoice will give them a date to use and the warranty is good for up to 5 years. I am planning on using it for longer than that. 5

[Low Profile] Arrived in less than 24hrs, Install is super easy and the read/write speeds you get are incredible. Make sure to slot it into a x16 PCIe slot. I initially had it in a x8 and was getting 4000mbs so the x16 helped get it up to 5500mbs. 5
