Combined with a high-performance SSD, Accelsior S brings cutting edge 6G performance to your SATA 3G system. Internal Storage Expansion at Lightning Speed With more than 500 MB/s of throughput, the Accelsior S dual-lane PCIe 2.0 card delivers flexible storage expansion - with a speed boost - to your Mac or PC. Accelsior S is the perfect complement to OWC's Mercury family of high-performance SSD's, allowing up to an extra 1TB of fast storage expansion. Just Plug and Play Mount a 2.5" drive to the Accelsior S, install in any available PCIe x4 (or greater) slot, and you're up and running with expanded high-speed storage. Use as a native, high-speed, boot drive or scratch-disk and boost capacity and performance. With no drivers or extra software needed, upgrading your PC or legacy Mac Pro tower with Accelsior S is a breeze.

OWC Mercury Helios Thunderbolt PCIe expansion chassis NOT COMPATIBLE: HP DL 380 G7, HP DL 380 G8, Dell PowerEdge R620, Dell PowerEdge T620 Drive Compatibility When used together, the Accelsior S and the 2.0TB Mercury Electra 6G SSD are compatible with the MacPro4,1 series and MacPro5,1 series. This device combination is NOT compatible with the MacPro1,1 MacPro2,1 or MacPro3,1 series. Note about throughput: PC Throughput PCIe 2.0 x4 slot or better is required. Use of a PCIe 1.0 x4 slot will reduce performance. Mac Pro Throughput 2009-2010 Mac Pro. Installing Accelsior S into any open x4 or x16 PCIe 2.0 slot will deliver full throughput 2008 Mac Pro. These models have two x16 PCIe 2.0 slots, which enable Acceslsior S to deliver full throughput. Installing Accelsior S into of the two x4 PCIe 1.0 slots will result in Accelsior S being addressed as a gen one, one-lane card with performance limited to real world 190-200MB/s data rates. 2006-2007 Mac Pro. These models utilize PCIe 1.0 slot which cannot be configured (even with the Expansion Utility in OS X) to address Accelsior S as anything but as a first generation one-lane card. As a result, Accelsior S performance will be limited to 190-200MB/s data rates. If maximum data rate speedis desired, we recommend the installation of a 2.5" OWC Mercury SSD in an open Mac Pro drive bay.

Review: Excellent for Mac! Rubbish for PC - UPDATE 14/05/2019 So i can confirm that these do in fact work in a PC. I recently put one of these into a PC with a Gigabyte Z390 UD motherboard, wanting to give it another chance despite when trying it in my dads PC and it didnt work. And with the Z390 UD it works flawlessly. So if you have this type of motherboard? I can say it at least works there both as a data storage device, and a boot device! ORIGINAL REVIEW BELOW: =================== I ordered 2 of these. One for me and my Mac Pro (from 2009) and one for my dad and his PC. On my Mac Pro this product works excellently, coupled with a Samsung EVO drive! Boots up in less than 15seconds (MacOS 10.13 + quite a few auto-running applications). However on PC? This thing does not work well. PC detected the card and that there was a drive plugged in however it was never accessible and there were alot of crashes. If attempting to use it as a main boot drive? Everything crashed, stating the boot volume was inaccessible. If trying to use just as a storage device? Crashes, freezing and in some cases totally inaccessible. The drive that was plugged into this was also fine and so not at fault. The requirements for use in a PC are very vague as well. Simply saying 'A PC with a PCIe x2 slot' does not help anyone. Their website wasnt much better either, touting the support for multiple Macs, but again when it came to PC it was a vague 1-2 lines. Nothing of use. In conclusion; Want to use this with a Mac Pro? Go for it! It should work perfectly fine, at least in 2009 Mac Pros so long as you put it in one of the 4x slots. Putting it in a 16x one seems a little wasteful especially when the graphics card is supposed to go there! Not sure which are the 16x and which are the 4x? If you look closely at the Logic Board of a Mac Pro (at least the 2009 ones) the PCIe slots are clearly marked 16x or 4x at the left-side end of the PCIe socket. Want to use this with a PC? Take caution! I dont deny that maybe my dads PC itself was a factor. The BIOS/Firmware on the motherboard does state that it supports PCIe booting, but it just didnt work, even as a storage device. So we had to return my dads one. I'll be keeping mine in my Mac though!
Review: Mind-blowing speed on MacPro 3.1, quick to install, brilliant for Video Work - Works brilliantly on a MacPro 3.1, running either Mountain Lion or El Capitan. I've paired it with a SanDisk Extreme Pro 480Gb, and am getting real-world 480Mb/Sec WRITE and 530Mb/Sec READ, which is 3.3 times quicker than a 1Tb Velociraptor 10,000rpm HD Drive. Using it with Premiere Pro CC 2015, it means the cache renders are just spectacularly quicker. Best thing of all, for MacPro users anyway -- NO DRIVERS REQD. You can plug it into one of the internal PCIe 4x slots (don't know if it works even faster on the other PCIe 16x not holding the GPU), and with two PCIe 4x slots free (after adding USB 3 card to the third one), it basically means if you buy TWO of these Accelsior S adaptors (plus the SSD to go with each), you can have 6 internal hard drives on a MacPro, and we can all stay up-to-date with the latest tech on an 8 year old machine.

### ⭐⭐⭐⭐⭐ The best upgrade for your aging MacPro
*by G***F on 18 January 2018*

This is the one thing (along with a good SSD drive) an older MacPro (late 2008 3,1) will benefit from most in bringing back some of its original mojo and speed. My boot ups went from 4-6mins before the Mac was ready for use to 60seconds from power button press to completely ready for use. All applications launch in seconds and working with my old MacPro is a real joy again. Amazing and well worth the purchase. True plug and play too. Plug it into one of the x16 pci slots loaded with a good SSD for the best performance.
