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.

Excellent!

Great card to speed up a SSD in an aluminium MacPro AND keep your 4 usual SATA slots for classic HDDs!
It's only slightly more expensive than a 2,5" adaptor but it's so much more useful!
Highly recommended if you want to get the best out of any SSD in your MacPro.

Fantastic way to renew an old Mac

My MacPro 2010 had become sluggish to the point that from boot until first moment of usability was around 20 minutes! I installed this SSD and put a fresh OS on it.

Got this and a 2TB SSD for my Z800 and it just works without complication. I am seeing 520+ MB/Sec read and write speeds.
If you have an older computer/workstation and are stuck with older Sata 2, I highly recommend this product. It's a no brainer. ;)

It was about time!
October 17, 2017
Purchased this to "boost" performances on my old MacPro version 3.1. Don't know why I waited so long. Delivery was quick, the SSD disk responds well and migrating my principal drive was a breeze using Carbon Copy Cloner. From start to finish, from installation, formatting and cloning the ex-principal drive onto the SSD drive took a little under one hour! I would recommend this item to a friend!

Just Great Availabilty with High Sierra not Raid Compatible.
October 8, 2017
Thanks so much for having a 2TB option available to use in place of my Apple Raid. Apple will eventually support Fusion Drives, but no mention of Raid support. This bundle is so easy to install. I transferred all of my files from the Raid using Carbon Copy Cloner, booted up to the new drive and installed macOS High Sierra and even updated to the Supplemental Update and am now good to go. I’ll probably be back for the recommended graphics card soon. I would recommend this item to a friend! This review is from DIY Kit: OWC Accelsior S + 2.0TB Extreme Pro 6G Solid-State Drive Bundle..

August 4, 2017
I was already running an SSD as my boot drive on a Mac Pro 5.1, so I didn't gain a huge increase in startup speed, but my apps sure seem to run smoother. Easy install, up and running in 5 minutes or less. A very cost-effective way to update your hardware, AND free up a drive slot. I would recommend this item to a friend!

Another Great Product by OWC
May 27, 2017
I bought this to put in a MacPro I am setting up as a home file server and now this leaves one more slot open for another large hard drive. It was an incredibly easy install. Installed a fresh OS and away we go. I leave the machine on 24/7 and this runs flawless. Only thing I ran into is that it wont let a machine fully go to sleep if you're using it in a desktop that you like to leave running. Other than that the acces time and reliability has been great!

Huge Speed Improvement!
March 20, 2017
Added this to my Early 2008 Mac Pro 3,1 and boot up times improved by factor of 5 and loading Photoshop & Lightroom went from 2 min and 25 seconds to an amazing 20 seconds! Everything appears to be improved! The only issue was Apple's Migration Assistant that didn't copy over all the software perfectly - some items needed to be reloaded.

MacPro 2008 I have a new machine!
January 17, 2017
I purchased the PCI card to install an SSD in my aging 2008 MacPro.
Installation was uneventful. It took less than two minutes from opening the Accelsior box, opening the MacPro, installing the card and closing the MacPro.
I am utterly stunned by it's performance! I feel like I have purchased a new machine.

Great idea, works exactly as expected
December 26, 2016
I'm very happy with this, since it frees up a regular drive bay. While it promises performance benefits, I don't really notice any, and would have to use benchmark testing to be certain.

Speed, Speed, and More Speed
November 23, 2016
I have resurrected my mid-2010 Mac Pro! Before I performed this upgrade, I was suffering through very sluggish performance and a six-year-old OS. I needed to upgrade to at least El Capitan to keep my recording studio up to date and wanted an SSD drive to become my startup disk. Now, my Mac starts up so quickly and my audio programs which normally have these beautiful load screens "while you wait," don't even pop up because the program just opens in a snap! It's impressive. I couldn't be happier with this upgrade. I already want another and have an empty PCIe slot just waiting...

Easy installation and awesome compatibility.
November 9, 2016
It really can't be much simpler. You install your SSD on the card with the provided screws, then install the card in your compatible computer, close it up and then power it up. The SSD I used was my boot drive and I didn't have to do anything further. The icon of the drive you install on it shows up with the external disk graphic, but there us no option to eject it by right clicking or dragging it to the trash. A little strange, but doesn't effect anything. 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.

Worth Every Penny!
August 19, 2016
It's allowed me to access the SSD in my 2010 Aluminum Beast MacPro tower vastly faster than when plugged into the built-in Sata bus. If the CPU in your MacPro is strong enough and tasks are bogged down by data read/write speeds then this product should be a must buy, I would recommend this item to a friend!

Did the job I needed it to!!!
August 15, 2016
While it didn't add what seems to be a significant amount of speed to my computer, (even if it is) it's just enough to keep my 2011 Mac tower going strong for a little bit longer. And for the price (around $50 I think) it's amazing.
I'm a video editor and my 5 year old tower was having trouble keeping up with 4k footage on Adobe Premiere for editing. I love being able to see the footage at highest resolution and wish not to do proxy editing if I don't need to. Using this device allows me to now be able to edit 4k footage on the drive that is attached to. It's also great that I now have another internal SSD drive for my computer.
I'm so glad a product like this is out there and at such an amazing price. Thanks OWC.

Added a SSD to a rebuilt mac Pro 5.1 and that really improved the boot time, seems about 5x faster, perhaps a bit more. 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.

Doubled the speed of my SSD
July 17, 2016
This product should be a no-brainer for any Mac Pro Tower owner. Not only does it double your SSD speed but it also frees up a hard drive bay if you need to add a large capacity hard drive.
BUY IT!
