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 Easy install, works as a fast pci boot drive for a 2008 Mac Pro July 4, 2020 I had it put together and installed within 10 minutes. You do have to screw the drive to the pci board which is easy. Once in I did a clone from my original 2TB Mercury SSD in my 2008 Mac Pro drive bay to this Extreme Pro 6G, I was able to boot from this faster SSD on the pci card located in slot 2 (16x) pci bay. Do not put it into slot 3 or 4 in a 2008 Mac Pro. It will work but a a speed slower than the original SATA III drive bays. Speed increased from about 275 Mb/s to 510 Mb/s according to Blackmagic speed disk test. I can now actually edit 4K video projects on this 12 year old Mac.

Rating: 5/5 Great combo June 27, 2019 I purchased the 480GB Pro 6G SSD and Accelsior S adapter into my 2010 Mac Pro 3.46GHz 12-core, it was easy to install and the speed benefit was instantly recognized. Previously, I was running an SSD from the drive bay not realizing that the SATA 6Gbps capability of the SSD is reduced to SATA 3Gbps speeds. With the Accelsior S adapter the 6Gbps speeds were achieved and the performance increase allows my 2010 MacPro to outperform my fully loaded 2018 iMac 18,3 (i7-7700K). Booting into MacOS takes about 5 seconds and overall system response time is almost instant.

Rating: 5/5 my mid-2010 Mac Pro is flying now... November 5, 2018 I was a little nervous about this (both the install and the technology, which I was too lazy to read about). I've had really good luck with OWC, though, so I gave it a shot.

**big** improvement over the same SSD in one of the normal drive slots.

Only weird thing is that the system sees it as an extrnal drive.

Rating: 5/5 Extended the life of My 2008 Macpro 3,1 October 16, 2018 Mac Sales, OWC Accelsior S with and a 2.0 GB SSD made my 2008 MacPro 3,1 not only usable, but a joy to use again. The Accelsior S really, really sped up my old mac, I am now running Mojave 10.14 (through a 3rd party patch) and the computer feels as good as new.

I highly recommend Mac Sales and commend them and OWC for coming up with such innovative products that extend the life of MAC Desktop and Laptop computers.

Seriously, my 10 year old MAC Pro is running better then new !

Rating: 5/5 Worked great on Dell PE R710 September 30, 2018 I was looking for a solution to get maximum out of dell PowerEdge R710 server. Onboard SATA ports only support ATA/IDE mode and SSD drive was getting 200 MBPS read write speeds. With this card AHCI is enabled and I got 530 MBPS read write and 56000 IOPS for read and write. I am using 1 TB samsung 850 ssd drive as boot drive on this card. One thing I did was I removed dell perc 6 card from the riser and updated bios to latest version 6.6.0 I would definitely recommend this to anyone looking to utilize old r710 servers for ssd drives. No drivers needed.

Rating: 5/5 Bringing back to speed Mac Pro Early 2008 (3,1) June 29, 2018 With the new Mac Pro only available in 2019, I decided to take the plunge and upgrade once more my 10-year old faithful Mac Pro, by adding 32GB of memory (and keeping 8GB of the previous 16GB to total 40GB) and installing a PCIe SSD drive. This allowed to install the OS (OSX El Capitan is the last update possible on this machine) and apps on the SSD and keep all user files on the original Macintosh HDD. After one failed attempt to do the configuration myself, I redid the process successfully exactly as explained in OWC's Youtube video (https://www.youtube.com/watch?v=Ou-heXnkPP4) except I did not clean/delete any system files or apps from the HDD so to keep it as a backup bootable for safety. The total boot time is now 2 minutes instead of 20. I also created a FCPX "scratch library" on the SSD that speeds up performance tremendously as FCPX constantly refreshes projects in the library during editing; then when finished I move the project (in FCPX) to the original HDD library. All other apps of course load and execute much faster. Perfect way to keep an old Mac Pro going.
