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.

I had the onboard raid controllers saturated with ssd's on the intel raid and spindle drives on the lsi chip. i am using the OWC Accelsior S as my boot volume. it is great with a toshiba q series 256 gb drive or an intel 530/535 series 240 gb drive.

fast, cheap and foolproof way to speed up your SSD
October 8, 2015
It works as promised... installation was a no-brainer and I measured a large speed improvement using the Blackmagic speed test app. Unfortunately for my application (pro audio) it didn't seem to make a difference for the way I work...YMMV. Also the computer seems to run a little hotter now according to my temperature app... the ambient and PCI slot sensors show a few degrees higher than if the SSD was on the SATA bus. It's to be expected, but something that could be an issue if you're already running too hot. I would recommend this item to a friend!

Works as advertised
September 19, 2015
I mounted a Samsung EVO 850 500GB drive on the Accelsior S and put it in my 09 8 core 2.93 Mac Pro.
After 3 months there are no problems what so ever. Blackmagic Disk Speed test shows in the low 500's throughout the various size tests. No sleep issues at all under Yosemite.
I'm buying a second one to go with another Samsung EVO 850 500GB drive

Easy Install - Works Great - Works fast
August 29, 2015
It's magic! Now I have 6G hard drive speed by installing this PCIe card with an SSD hard drive installed on the card. The SSD installed very easily onto this card and this card went into the PCIe slot without problems. I could have installed this card just above the factory video card on my MacPro but this card extended just MMs above the video card cooling fan inlet. So I installed this card into a higher slot and now there is no potential for an airflow problem. I don't know if there would have been a problem of air getting into the cooling fan inlet, but this card seemed too close to the inlet to risk leaving it there - so I went up one PCIe slot.

Awesome bargain!
August 11, 2015
Just got one of these an paired it with a 2TB SSD I had that was being choked by 3Gbps SATA...
Exactly as advertised I'm getting 500+MB transfer rates (as measured by Blackmagic Speed Test) and it installed Yosemite and functions as boot drive with zero issues...
Great buy that unlocked an otherwise wasted resource for me! Two thumbs up!

A great option for any existing SATA SSD in the MP
July 27, 2015
I have that card now for over two months, and I am very satisfied with it. OWC delivered a great upgrade option for my SATA SSD at a great price point. My Mac Pro 5,1 3.33 GHz is a lot faster. I am very happy with the result. Programs start a lot faster. With the OWC provided HDD icons, my start up disk comes in a typical OWC blue on the desktop as well. OWC upgrades are much appreciated in Germany, Thanks! I would recommend this item to a friend! This review is from OWC Accelsior S: PCIe to 2.5" 6Gb/s SATA SSD Host Adapter.

Great for photo editing when linked with an SSD
July 26, 2015
When Adobe Lightroom 2015 CC and Photoshop CC came out this year my Mid 2010 Mac Pro with 32GB of RAM seemed buggy and slow. I was trying to figure out a way to speed things up so I installed the OWC Accelsior S and mounted a 240GB Mercury EXTREME Pro 6G SSD on it. I installed my Lightroom catalog on the Mercury Extreme drive as well as assigning it as my Lightroom cache drive, Photoshop scratch disk and On1 scratch disk and the results were amazing! Photoshop says my efficiency is 100%, Lightroom runs smoothly and my editing speed has increase dramatically. If you are photo editing in Lightroom and Photoshop this set up is for you and the best part was that it was an inexpensive boost to my productivity. I would recommend this item to a friend!

Couldn't be an easier upgrade - simple to install and doubled my transfer rates.

Does what they say
June 24, 2015
Super easy to install and understand, and the speeds are as advertised (depends on the SSD). No drivers required. The SSD will show up as an external one, since only disks connected to the Mac SATA ports will appear as internal disks, so you can accidentally eject it, but that's a non issue if files on the disk are in use (you can always mount it with Disk Utility again if needed). Boots well, and there were no issues cloning the old boot disk to the new one with Carbon Copy Cloner, including the recovery partition. Before you install the SSD on the card, be sure it has the latest firmware. I would recommend this item to a friend! This review is from OWC Accelsior S: PCIe to 2.5" 6Gb/s SATA SSD Host Adapter.

New life, what a difference.
May 11, 2015
Extremely easy to install, put in 4 screws to hold down the SSD. We set this up as a boot disc/program disc. It makes a significant difference in performance. We saw a 300% decrease in processing time on Final Cut Pro (less than 10 minutes for a process which used to take 30+ minutes) to transcode and render a 35 minute movie.
Strongly recommend for anyone with a 2012 Mac Pro.

Mac Pro feels like new
May 4, 2015
Installed this in my Mac Pro 4,1 8 core with 24GB of RAM I've had for 5-6 years. Was already running an SSD as the boot drive in the OWC bracket on the SATA 2 backbone. Took about 5 minutes to switch it over and boot it back up. No configuration necessary at all. Boot time is a bit slower until you get to the login screen but that's more than made up with how snappy the whole system is now. Logic and Pro Tools both starting in half the time, seems the same as when I load them on a Retina MBP. Heavy sessions run smoothly. With the CPU almost pegged the disk is barely lighting up (running sessions of another SSD installed on the SATA2). I haven't tested putting it to sleep as I use a UAD2 card that doesn't support sleep mode. I'll definitely be putting one of these in a client's same model Mac Pro as the price to performance is too good to ignore. Great job OWC. I would recommend this item to a friend!
