    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.

    Rating: 5/5 Pretty good for the price October 9, 2018 This is hardly a world beating SSD but that is by no means a criticism.

    For the price, it has been an excellent addition in helping to restore a 13" 2010 MacBook Pro from being so slow to be unusable to a really good little laptop for someone wanting to browse the web, do some email, use Word, back up the photos on their iPhone and watch YouTube.

    For the right use case, I can recommend this product.

    Rating: 5/5 Easy install. Speed increase even in an old Mac Tower August 29, 2018 I bought 2 250gb SSD's for 2 different old MacPro towers. It was a little tricky but not difficult to attach them to the drive sleds, but once attached, install takes about 2 minutes. The software install was a bit harder mainly due to my stupidity. On one machine I used restore from Recovery and then Migration Assistant. Very slow and NOT recommended. The other machine, I used Carbon Copy Cloner which is a wonderful piece of software. Basically 1 stop shopping. After the install, I rebooted into my SSD and some more stuff described next. The SSD was not big enough to handle my entire prior drive, so I did not transfer Downloads, Documents, Music and Movies. Then, when the new SSD was ready, I set up soft links to the files on my older drive. Everything works and I still have about 48gB left on my 250gb SSD,. Boot up time is way faster. I wish I could have afforded larger SSD's, but these are fine.
