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.

Rating: 5/5 Excellent product providing additional disk March 29, 2018 I have bought this host adapter plus a 1TB OWC 6G SSD in order to provide an additional disk for my 2010-vintage Mac Pro. The disk mounts as an external disk ergo is suitable for loading macOS (as opposed to any version of Windows, which must be loaded from an internal disk). You just plug the adapter in, and it works without any hassles.

Rating: 5/5 Excellent! March 17, 2018 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.

Rating: 5/5 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!

Rating: 5/5 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.

Rating: 5/5 As Advertised 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.

Rating: 5/5 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!

Rating: 5/5 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...

Rating: 5/5 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.
