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.

Rating: 5/5 Saved our old iMac August 25, 2020 I am using this drive as the boot drive for an old iMac that essentially had an internal laptop drive. Those drives became extremely slow over time, even with defragging, and I decided to try using this as the boot drive. I know it isn't recommended to permanently boot to an external, but it saved my computer, which is a 2013 model, and feels like a brand new computer now. It is about 12 times faster than before, and this drive is extremely well executed in a lightweight yet rugged enclosure. Highly recommended!

Rating: 5/5 Quality product October 26, 2018 Own three of these and use as backup drives for three Macs. Have been a customer for over 15 years. Have purchased ssd’s,external burners and older hd external drives that still work,but not as quick as the ssd external drives I now have. OWC product line is superb. It covers the gamut of anything you might need. Tech support is outstanding. The diy videos are easy to follow. Dealing with OWC is a pleasure! I would also add their installation service. 4 years ago they added a data doubler plus a ssd to my 2012 macmini. Needless to say. That macmini is my go to Mac for doing taxes etc. The original drive is the backup. All my important stuff lives in it. Still use an external just in case. CC Cleaner installed.

Rating: 5/5 Great External Drives for Backup and Storage September 18, 2018 I've now purchased several of these for various uses, and they all work great! The spinning drives are fast, work off bus power (with USB 3.0) so no extra cords, and take up very little space. I use the Mercury On-The-Go spinning drives for what I term "relocatable" applications. That is, I want to be able to easily take it with me to use in a hotel room, or in our RV, but it doesn't need the durability and "use on the move" capability of a SSD. The spinning drives are high quality, and relatively cheap (compared to a like-sized SSD), so I don't mind some overlap or duplication. In fact, if you're not moving big data files around, the 5400 rpm drives are really a steal. I have several of the On-The-Go Pro drives, both SDD and HDD, that I use with my MBP since it's a bit limited on storage with 256G SSD built in. So, I've pretty much eliminated data storage on the laptop and just use that SSD for applications, and then I keep all the data (e.g., pictures, GIS data, audio files, etc... on the external drives. A nice extra is that I have a dedicated Photos HDD that has my Lightroom library on it, and I can take it with me on a trip, work with the photos on the laptop, and then when I get home, use the same drive on my desktop for work and finishing on a bigger screen. It's working great, and I even have a separate drive that I use as my Windows 10 gaming drive. The price, size and performance of these OWC Mercury On-The-Go drives are perfect for this type of use.

Rating: 5/5 Perfect Win 10 external drive August 12, 2018 The 256G SSD on my MBP was maxed out with a Bootcamp partition. After reading a Rocket Yard blog article on setting up Windows to boot from an external USB drive, I didn't wait long to select this OWC 120G SSD portable to do my install. It's PERFECT!! The drive is small, tidy (USB 3.0 bus power, no power cords!), and FAST. And, the SSD is bump and jostle resistant, so I can use it on the go. I was able to remove the Bootcamp partition on the internal drive and get all the space back. The external boot operates with no perceptable performance loss (the Win 10 OS and drive are for games). I have a couple other ext HDDs that I use for backups and pictures, but I really appreciate the additional ruggedness of the SSD. The OWC enclosure is rugged (enough), takes little desktop space, and fits neatly in a laptop bag. It fits my needs perfectly, and has been running without a hiccup.

Rating: 5/5 Great backup and archive solution December 30, 2017 Grandson used his MacBook Pro with Retina for two and a half years of college. His small solid state drive was nearly full and cooling fan was running regularly. He had no external drive and no backup plan! This drive was a great solution at a very reasonable cost. Created two partitions, archive and backup. We moved seldom used files to archive and set up Time Machine for backups. This simple addition will keep his 8 gig, 120 Gig SSD MacBook relevant for the foreseeable future at a very reasonable cost. Thank you Macsales!

Rating: 5/5 LOVE these pocket-sized multi-terabyte storage units December 16, 2017 I've been using these OWC On-The-Go external drives since at least 2012, and love 'em! Have [at least] 18 of 'em - 500GB to 2TB; most USB2/USB3; some Firewire400-800/USB2or3. Something like 20-30 TERAbytes in total. Got most of 'em with the mass-store already inside, but also got a few 0GB cases and stuffed my own drives in 'em (usually extracted from obsolete computers on the way to recycling). Nightly backups (using wun'erful Carbon Copy Cloner); off-site back-ups; easy sharing of monster-sized files; etc. [Well okay - so maybe it has to be a slightly largeish pocket. :-) ]

Rating: 5/5 Compact/Fast July 5, 2017 A nice little portable package, that's faster than most portable HDs. One potential issue I've had is with connecting it to a hub. It "clicks" and won't fire up when attached to one of my powered USB 3 hubs. It must be a power issue as the drive works great when connected directly to the MacPro and Powerbook. Could be a hub issue, though other peripherals are working, so I'm not sure it's that the drive's power requirements are a bit steeper than the hub can handle.
