Special note for specific 2009 iMacs, 2008-2010 MacBooks, 2008-2009 MacBook Pros & 2009 Mac mini.
We highly recommend the use of a SATA 2.0 (3Gb/s) SSD such as the OWC Mercury Electra 3G for the following Macs:
iMacs w/ Model ID:

While a 6G SSD does function, it will only do so at SATA Revision 1.0 (1.5Gb/s, 150MB/s) speeds rather that the SATA Revision 2.0 (3.0Gb/s 300MB/s) speed the computer can deliver.
The Mercury Electra 3G SSD is the OWC recommended upgrade option for the Macs listed in the special note above.

This OWC SSD Model is compatible with nearly any Mac or PC model with a Serial ATA connection (SATA, SATA 2.0, or SATA 3.0) including: Learn how to find your Mac's model ID

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.

  2. 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.

Rating: 5/5 Works Great March 5, 2017 This is just what I needed to create a clean install of macOS for emergencies and occasional diagnostics/cleanup. I've installed it in an unused Mac Pro bay for that purpose. I didn't need a very large volume, just large enough to hold Sierra and a few utilities. This arrangement is much faster than relying on a USB flash drive or an optical disc. Very satisfied with the purchase.

Rating: 5/5 Works great with my 2011 MacBook Pro March 2, 2017 I actually bought the Samsung 850 EVO SSD before and had a lot of problems with it with my late 2011 13" MacBook Pro. The system often gave me the prohibited sign at bootup. It would also freeze at random times and need a hard reboot. After I installed the OWC SSD, all my problems went away. I have yet to encounter any problems with it, and I've been using it for 2 weeks now.

Rating: 5/5 Back from the Dead January 5, 2017 My 2010 MacBook Pro 7,1 was so dead and slow, I knew it was no or never for open surgery. A friend referred my to MacSales and after their simple review of what my computer was capable for upgrades, I got 16g of Memoras y and 240g SSD, for under $250(US). I live in Canada so after exchange and duty, it was still less expensive than obtaining through other third parties. The easy installation videos, and a little help from live chat, my old beauty is like a two year old on Christmas candy. I'm a home user, but even with the videos, I was comfortable with installing a new SSD. I'm so happy and content with the product Other World Computing and MacSales helping and making sure they are available for any issues.

Rating: 5/5 Super Fast and Excellent Customer Support December 13, 2016 I purchased a 480GB Mercury Electra 6G 2.5-inch 7mm SATA 6.0Gb/s Solid-State Drive along with 16 GB of RAM to upgrade my Early 2011 MacBook Pro. It's now super fast. I'm just disappointed that the new Macs are all hardwired so we can't upgrade them ourselves.

As a follow-up I also purchased a 240GB Mercury Electra 3G SSD 2.5" Serial-ATA 7mm 3Gb/s Solid State Drive for another MacBook Pro. It ended up crashing, but I sent it back and received a replacement, no questions asked. OWC stands behind their products.

Rating: 5/5 Solid product December 9, 2016 Note that I didn't handle this SSD. A coworker installed it for me. But since having installed it the performance on my machine has been so much better and I'm really glad I purchased the SSD.

Rating: 5/5 Super Fast Now! December 2, 2016 I replaced the HDD on my iMac 21.5 late 2013 with the SSD drive from OWC, and the speed is amazing. Would highly recommend it. The only thing I missed was that there was also a faster SSD but a bit more pricey [only $10 or $15 higher] sold by OWC, but somehow I missed it, and wish I would have gone for that one. I also upgraded the ram from 8GB to 16GB (got the boards from OWC), and it's unbelievable how much faster the computer has become. I went for 240GB SSD, as it was sufficient for my usage, but in hindsight, wish would have gone for the 500GB, since I could have transferred some of the files on my 3TB external HDD to the SSD, and retrieve them much more quickly when I needed them!

Rating: 3/5 Huge difference in performance but formatting takes a while! November 27, 2016 This hard drive is great - my macbook pro is way faster than before. The installation video is very clear and it took me about 10min to replace the original hard drive.

There a HUGE issue though. This is not stated anywhere: The hard drive comes unformatted, and once I replaces the original hard drive and turned the macbook pro back on, there was a big error message on the screen because there's no operating system installed. And this is no fun! I'm surprised that this fact is hidden from the customers.

But then there's a huge PLUS. I called OWC customer service, and these guys are very knowledgeable, friendly, and customer focused. The customer rep guided me through the process of bringing the new hard drive back to life, step by step, click by click. The process took hours to complete, but you only need to be on the phone for about 20min until you kick off the installation process (installation of the new operating system)

Overall, I like the product but the fact that I wasn't warned of this issue in advance, is a huge issue for me. Unfortunately, a novice will not be able to complete the formatting process.

Rating: 5/5 Huge speed boost for 2010 Unibody Macbook November 23, 2016 I replace the HDD in a 2010 Unibody MacBook with one of these SSDs and it made a massive difference in the performance of the machine. It booted really fast, apps opened on only one or two bounces, and the whole OS just ran substantially faster. Higher recommended for new breathing life into old Macs.

Rating: 5/5 $200 upgrade worth $1000 November 18, 2016 Older Macbook Pro with a 5400 RPM hard drive. So slow with the new upgrades it was almost unusable. Installed this SSD and now it screams. About as fast now as my newer Macbook Pro. Worth the investment and took me less than 15 minutes to be done swapping the drives.

Rating: 5/5 Fast and reliable November 18, 2016 This thing is fast compared to a traditional hard drive. I own a few other OWC drives and they are still going strong after three years. Well worth it!
