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. Specifications provided by SandForce.
  5. 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 Macbook is so much faster now. February 7, 2018 Macbook boots up in half the time. No more lag. Its just snappier. Better than it was when I bought it new 10 years ago. Decided to upgrade instead of buying new because my machine works just fine, just needed an upgrade. I wish I could upgrade my USB ports to 3.0 instead of my current 2.0.

Super impressed with the great install videos. Just make sure you have the required Torq screwdriver when you install. I always feel confident that I’m getting the right product for my machine. Very happy with the hard drive.

Rating: 5/5 Nice speed gains!! August 31, 2017 After installing this in my Mid-2010 MacBook, I was surprised at the speed. Now my Mac boots in a fraction of the time. Performance is great, even under Windows, which I installed using Bootcamp. I highly recommend this to anyone needing more speed from their Mac. The speed gains are real. The only downside is the price. Other than that, this is a worthwhile investment.

Rating: 5/5 Successfully upgraded my 2009 laptop! August 1, 2017 I've heard great things about OWC and their reliability for anything Macbook-related. I ordered to an Asian country which is where I currently am and the shipping was great at under $5! It did take a bit longer than their intended date by around one or two weeks but that's all considered how far my country is. The bubble-wrapped letter kept the contents from OWC safe from harm and all was in perfect condition, packaged as new. The product works as intended. The only downside I've only ever heard of macsales is the shipping, but remember that once it's shipped, it's out of their hands how it all works out. If you're paranoid of packages getting safely (as I am), I highly suggest you pay extra for faster + tracking service. Thank you MacSales for giving my university laptop the boost it needs before the school year!

Rating: 5/5 Off to the races! June 13, 2017 I replaced the failing hard drive on a PC laptop with a 60 GB SSD drive from OWC. The screws for the mounting frame from the laptop seemed large for the SSD drive, but after calling OWC tech support, I went ahead with the installation. I then installed Ubuntu Linux on the SSD, and performance is amazing. It takes 15 seconds to boot from a cold start and about 2 seconds for a browser to connect with the Internet. Guaranteed, that laptop never did anything so fast!

I just wish the cost of SSD storage would come down further, but that's not OWC's fault.

Reviewer: MattyH
Rating: 4/5 Even At 3G, A Huge Improvement May 27, 2017 Bought the 3G instead of the 6G because it was on clearance and had some pretty immediate pangs of buyer's remorse, but after installing I am very pleased. My mid-2012 MacBook Pro feels like a new computer with this upgrade (alongside 16GB of RAM and a new battery, also from OWC). Certainly gave this old laptop a new lease on life. My only note: the screws that connect the drive to the mounting rails from my old laptop took way more force to fully thread than I was comfortable with: I was worried I was breaking my new drive! It was probably the thread tape/loctite that was from the original installation, but with a bit of muscle, I was able to drive them fully home, and it fit like a dream.

Rating: 5/5 SAVED MY TRUSTY G4!!!! May 23, 2017 This thing TOTALLY brought me trusty old MDD G4 back to life. Actually transfers data faster than my brothers Mac Pro!!! Like having endless Ram/Scratch.

Only thing is if you delete a big bunch of stuff, it can sometimes take a bit of time to auto-trim (like 5 minutes).

Rating: 4/5 Works good as an external drive February 24, 2017 I was looking for an SSD that would speed up my Late 2009 Mac Mini. Even with the 266 Ghz processor, things were slowing down and boot-up was too long.

I was not ready to buy a new computer yet. So, I purchased the OWC 480GB Mercury drive.

I didn't want to go inside the computer's case so I just bought an external metal enclosure from OWC and hooked up the drive via the Firewire 800 ports.

It has been a few months, and I can't remember exactly how I transferred the files from my old hard drive to the new SSD. I think I just used Apple's software and a copy of the software on another external hard drive that I use for Time Machine backups only. But everything transferred over without problems.

The performance is quite good. Initial start up is MUCH faster and there is less lag time when opening applications. I realize I would get even faster performance if the drive were internally mounted and I may do that eventually. But for now, it works good enough.

Rating: 5/5 FAST DRIVE February 14, 2017 Although the process of swapping my HDD for an SSD was quite a bit more complex than it was supposed to be, that was largely because I didn't get the kit with the enclosure. If I had, cloning my HDD to the SSD would have been much easier and would have significantly reduced the time necessary to get my laptop running again. Take my advice and get the version that comes with the enclosure and tools. It's only a few dollars more and you get the necessary tools as well as the enclosure, because the drive arrives sans tools. If I hadn't recently replaced my battery with one from OWC, I wouldn't have had the necessary tools to do the job. My only complaint with the actual drive is how easy it is to cross-thread the old positioning posts when installing them in the sides of the new drive

Rating: 5/5 Good Buy February 4, 2017 My 2008 MacBook Pro was on its last leg and I purchased this SSD drive and it brought my MacBook Pro back to life. I went from a four minute boot up time to 30 seconds. Also the technical support from installing the new drive to transferring the data was above reproach.
