Standard Mechanism

    Release Candidate (RC) firmware set

    There are two kinds of firmware for SSDs Mass Production (MP) and Release Candidate (RC). Prior to an MP firmware release, there are beta firmware releases and an RC firmware release. Often, the RC is the same as the MP release, however there can be small changes and bug fixes made between the two. OWC has evaluated the RC for the 6Gb/s SandForce 2281 Processor and found it to be stable with no issues reported during our testing. However, as with any evolutionary product, issues may surface as different usages and configurations are employed and it is important to understand that there will be further updates and revisions.

    Since no firmware update is currently offered for the OWC Mercury EXTREME Pro 6G SSD, no update page exists. To see the typical steps involved with a self performed field firmware update, please visit our 3Gb/s product update page at: http://eshop.macsales.com/Customized_Pages/Framework.cfm?page=sf_firmware.html

    It is important to note that the current firmware update tool requires the use of Windows XP/Vista/7. OWC is currently working on a Mac OS based update tool, but we do not have an exact availability date.

My most recent purchase was an OWC external HD. After receiving my product, I did have a few technical questions and needed help from the macsales team. I contacted them via email and my questions were very promptly, professionally and thoroughly answered. I highly recommend!!

Rating: 4/5 Delivers Almost Everything I Expected November 3, 2016 OWC hard drive reliability is unsurpassed in my experience. My 10 year old 500GB OWC Mercury Elite-AL Pro is still going strong backing up my Power Mac G5 (early 2005). And now two 1TB OWC Mercury Elite Pro minis are backing up my Mac mini (late 2014). One star deducted for confusing wording in specs regarding Mac boot-ability. The specs note should clearly state that pre-2008 Intel Macs and non-Intel Macs will not be able to boot from this external enclosure. Period.

Rating: 5/5 Works great once I figured out how to hook it up November 3, 2015 At first, the drive would power on, but not show up anywhere on my computer. I looked on OWC's website and couldn't find anything helpful. Finally, after trying everything I could think of to get my MacBook Pro to acknowledge the drive, a friend suggested I plug both the USB and Firewire into my laptop. This did the trick! I just wish I had known this first before I spent countless hours troubleshooting and getting very frustrated. That being said, now that the drive works, it does what it is supposed to do and I have no problems out of it.

My only drawback was the packaged software and setup instructions, both are flawed, however, a call to the techs was the solution, by the way, they direct you to apple software for formatting and setup which works seamlessly...the techs are very helpful. I think the price/product ratio is very good also, as I've purchased a number of upgrade items and I always go to OWC.

Rating: 5/5 Great for off site backup. June 20, 2015 I already have Elite Pros for backing up our systems. The Mini is handy for a weekly backup that I keep in my fire safe. If my system (and its backup disk) are lost to fire or theft, I can use the Mini to boot up on another system. Belt AND suspenders. This is the second Mini I have purchased from OWC. Now, both my wife's system and my system have this additional recovery ability. All my disks from OWC have performed flawlessly over the years -- some way beyond their warrenty period.
