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.

  1. 1GB = 1,000,000,000 bytes. Total accessible capacity varies depending upon operating environment (typically 5-10% less). The actual total capacity will depend on your own defined file settings/preferences. 
  2. In terms of standard gigabytes, 1GiB ≈ 1.074GB and refers to the actual formatted capacity of shown under Mac OS 10.5 or earlier and Microsoft Windows OS.
  3. Specific application environments such as temperature and duty cycle will affect the overall reliability.
  4. Temperature reporting is currently an unsupported feature because due to the operating characteristics of SSDs, it is highly unlikely one would ever exceed an OWC Mercury SSD's stated operating temperature ceiling of 158F/70C. However, we are looking into supporting this feature in the future via a firmware update. Firmware updates can be found here: http://eshop.macsales.com/tech_center/OWC/SSD.
  5. Firmware support for Legacy Mac Models to enable SATA Bus Matching for full SATA 3Gb/s and SATA 1.5Gb/s bus enablement, even on models that are known improperly clock down with the use of a 6Gb/s Hard Drive or SSD. This model SSD has support to specifically ensure SATA Bus clocking to the maximum speed available from the SATA interface it is connected to.

Rating: 5/5 I really did do it all by myself. May 7, 2016 This really was quite easy to install in my MacBook. My only real hiccoughs were in getting data transferred, and that was because I had so darn much of it. My old drive, which also came from OWC, was easily removed and installed in the plastic case.

I would recommend this item to a friend!

Rating: 5/5 Thank God for the video! January 28, 2016 My most daring repair/upgrade to this point, the handholding by repeatedly watching the OWC video was a huge confidence builder. The operation went flawlessly, with my daughter anxiously on as I removed and replaced the innards of her beloved MacBook. It was a resounding success and has been operating flawlessly ever since.

Rating: 5/5 Did the trick - Macbook pro runs much faster January 16, 2015 Very happy with this purchase. Installed this HDD along with a new HDD cable in my mid 2009 macbook pro. Runs much faster now and quadrupled my storage. Installation tutorials are very helpful.

Rating: 4/5 Good product, instructions hit-n-miss July 17, 2014 The hardware replacement was a piece of cake, using the instructions on this site. The sofware portion was a lot less friendly, with my experience not quite matching what I was expecting from the instructions. The OS has to reinstall itself and upgrade itself, which led to having to re-register Office, etc. It took a lot longer than I was expecting. The Time Machine backup was essential.

Rating: 5/5 My MacBook 13" is a dual drive speed and storage demon! May 11, 2011 OK so a few months ago I put a 60GB OWC SSD in the optical bay of my MacBook Pro 13" using the OWC Data Doubler.

I left the stock 500GB 5400RPM drive in the drive, but I wanted more storage options and faster speed than a 5400 for moving large files around. The OWC SSD lets me work fast and the 7200 750GB lets me store big and fast(ish)... it's no SDD of course, but is still much faster than the stock drive.

Now I can partition, have an in computer time machine, multiboot, large storage, and an SSD powered machine all from one little amazing laptop.
