Add Up to 32TB (or more) Externally
with Two eSATA Expansion Ports In addition to the ultimate SSD upgrade, the Accelsior E2 adds two eSATA storage expansion interfaces to any Mac Pro. Achieve faster than internal drive speeds with up to 600MB/s performance per drive. That's a whopping 6x faster than the fastest stock Mac Pro external interface of FireWire 800 with up to 100MB/s data rates.

RAID or Single Drives,
The Choice is Yours A variety of single and multi-drive RAID solutions can be connected via Accelsior E2's two eSATA expansion ports. You can also create a RAID array with Apple's Disk Utility, SoftRAID, or various software RAID applications for PCs.

Note about compatibility and throughput:

Compatibility:
- Compatible with all eSATA equipped storage solutions.
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 into any open x4 or x16 PCIe 2.0 slot will deliver full throughput up to 785MB/s.
- 2008 Mac Pro. These models have two x16 PCIe 2.0 slots, which enable Acceslsior E2 to deliver full throughput up to 785MB/s. Installing Accelsior E2 into of the two x4 PCIe 1.0 slots will result in Accelsior E2 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 E2 as anything but as a first generation one-lane card. As a result, Accelsior_E2 performance will be limited to 190-200MB/s data rates. If maximum data rate speed up to 285MB/s is desired, we recommend the installation of a 2.5" OWC Mercury SSD in an open Mac Pro drive bay.
eSATA Expansion Ports:
- Compatible with all eSATA equipped storage solutions.*
- A sleep conflict may be encountered when using certain eSATA chipsets via the eSATA ports when booted to the Accelsior E2. See the specifications tab for affected solutions where System Sleep mode MUST be disabled in order to ensure reliable operation. Allowing system sleep to occur while one of the affected external drives is connected via the Accelsior E2 eSATA ports could result in loss of data following wake from sleep. Although the above are our general recommendations for use, wake from sleep has been determined to only be an issue when the Accelsior E2 is used for startup (SSD or eSATA connected device). We are working with our partners to see that the sleep/wake function is fully supported with all solutions and startup scenarios.
Dual Card Use/Booting:
- Dual Accelsior_E2 Usage. The use of two or more Accelsior_E2 SSDs requires OS X 10.6.8 or later.
- Windows booting is only supported in slot #3 on a 2008 Mac Pro (with model ID MacPro3,1). To boot Windows on an Accelsior E2, only one Accelsior E2 can be installed at a time. OWC Dual Boot Enabler for Apple Boot Camp required for use with Boot Camp utility. Download here.
- 2006-2008 Mac Pro (with model ID MacPro1,1; MacPro2,1; MacPro3,1). Due to an Apple limitation, any volume located on a Mercury Accelsior_E2 SSD will not appear in the "option boot" menu. A volume installed on an Accelsior_E2 can be set as the Mac Pro's boot volume through the "Startup Disk" pane in System Preferences.

*Requires 6Gb/s certified cables for connecting to eSATA drives - available separately. Not compatible with port-multiplier enclosures. The eSATA ports do not support hot-swapping. Accelsior_E2 eSATA ports are bootable.

Rating: 5/5 I now have two! September 20, 2016 I've had this card in my Mac pro for about two years. It is amazing how much it improves the performance over a Hard Drive. Sadly it failed. As it was my main drive, I ordered a new one as it would have my computer up and running within a couple of days instead of a week or two if I waited for the replacement (under warranty) Replacement was sent and I would have another back-up setup - you can never have too many. The two memory blades were replaced on the original PCIe card but it turned out that it was the card itself with the problem. probably a very rare occurance. OWC replaced it completely and now it all works fine.If the drive suddenly dies, then it is the SSD memory blade. But if it starts to act up then it is the card. Still recommend it highly!

After a few days of "option" selecting it as the boot drive during start-up (I have another sata drive with the same OS) my Mac remembered it as the primary start-up disk. It's really fast! Love the speed. However, is anyone else's Mac showing the drive as a SATA external (rotational) drive in Disk Utility and System Reports?

Rating: 5/5 Easy Path to Great Speed June 9, 2016 I've been thinking about an SSD upgrade for my mid-2010 Mac Pro for some time, but didn't realize a PCI option was available until an earlier, used model turned up in your Garage Sale. The E2 seemed an even better deal, all things considered, and thanks to your installation video it was almost as easy as a memory chip click into place. Your instructions for setting up my new SSD start-up disk were clear and a big help: El Capitan downloaded and installed in about an hour, and it took less than an hour and a half to transfer via Migration Assistant all of my applications and settings from my original start-up disk, which is now still waiting as a back-up or repair disk on my Mac. I was very happy to discover that my copy of Adobe CS6 still performs all the tasks that at lest I need on this new system, and that even my now venerable copy of DVD Studio Pro works better and faster than it did under Yosemite!.From the moment I press the power button it takes about 20 seconds for the finder to load, and many apps, as promised, open in a flash. It feels as though I've bought the computer upgrade I couldn't afford!

Rating: 5/5 Two cards in one for Mac Pro 3,1 users April 11, 2016 The speed and quality of the PCI card is advertised. For those Mac Pro 3,1 users like me that don't have an extra high speed PCIe slot to plug in a SATA 6 card, you might try what I did. Reroute the two eSATA ports back into the inside of the Mac Pro using a eSATA to SATA connector, buy two Newer Technology 3.5" to 2.5" adapter cards to fit a Mac Pro, grind or cut off the SATA 3 connectors on the Newer Technology adapter, Put Right Angle SATA 6 connectors on the SSD's you installed in the Newer Technology cards (they fit now because you removed the SATA 3 connector) and connect the other ends of the SATA 6 cables to the Accelsior E2 Mercury card. You now have 2 of your 4 internal Mac Pro hard drives running at SATA 6 speeds, powered by the Mac Pro. Add software raid software from MacSales if you want for even faster speeds than SATA 6.

Rating: 5/5 Highly recommended for Photoshop March 22, 2016 I purchased this PCIe SSD to speedup the computing processes in my 2010 Mac Pro when working in Photoshop and Lightroom. I have not been disappointed; these programs are very large and many tasks are processor and memory intensive. The SSD shortens processing time very significantly and gives me two eSATA ports to connect to external drives for storage - a win-win. I strongly recommend this card to any Mac Pro user, especially for photo or video editing.

Rating: 5/5 Quenches my need for speed!! February 27, 2016 My 5.1 Mac Pro boot times were sooo slow! It would would take more than 5 minutes for my Mac to boot up and stabilize. All my programs would take an inordinate amount of time to start and load. My UAD card would hardly ever work correctly. One of my trusted friends advised me that using a pcie card as a boot/program drive would give my Mac a new lease on life. After Conducting research, I decided that the Mercury Accelsior would work best for my needs. Once installed and tweaked, this card has worked flawlessly. Boot times are less than a minute and my programs/UAD card loads quickly without a hitch. One of the best purchases I made to hot rot my Mac!!!

Rating: 5/5 Soooo FAST January 3, 2016 same as USB 3 Pci Card... No need to install anything. Plug it & work. On Mac pro 5.1 Pci-e 16 ways = 610 MB/s only far away under 823MB/s but work great. No noises, not hot &... no external SATA III wires included :'-( can't test external ports.

Rating: 5/5 Working Great December 28, 2015 One thing to note is that you need to keep the original boot drive installed. If you do a PRAM reset, your MacPro will need it as it will be unable to find the PCIe SSD. Installs easy, works FAST. Cuts 23 Second boot time down to 11-12 seconds.

Rating: 5/5 Greased Lightning October 18, 2015 Accelerated my Mac Pro and made life worth living again. But even better than the card itself was the support from OWC. I had a bit of trouble formatting it and they helped me within minutes-- and cheerfully! The cynical side of me was (and still is) looking for a catch. But there isn't one. They're just that good.

I only wish I needed to buy more things...

Rating: 5/5 Made MacPro 5,1 very fast. October 15, 2015 Easy install, ( Hey! its a PCIe card). The speed Is "WOW" It is like having my old machine run like it was new. This Mac Pro started out as a 2009 model 4,1. 2x 2.6 (8 core). in late 2011 I added 32 RAM 1066 (OWC match set) In early 2013 with firmware it became a 5,1 (2010) and added 2x 2.93 (12core), 32 Ram 1333. In late 2015 installed 2x 3.46 (12 core). The last CPU upgrade did not really improve the speed. I decided to try this Mercury PCI card. I was not disappointed. Boot up time is 14 seconds. and no lag waiting for apps to preform. P.S. The OWC 32 Ram 1066 became 1333 with the firmware update.

Rating: 5/5 It's Fast! October 14, 2015 Everything during normal use works at the click of a button or tap! Installing the card was easy and I did a fresh install of El Capitan on it. Don't forget to install the driver for it from OWC!
