Mac / USB 3.0
Mercury Electra 6G SSD
Upgrade Your Internal Drive
Get more storage when you upgrade or replace the existing 2.5" drive in your Mac mini
The Drive and Tools you need to upgrade or replace the existing 2.5" Drive in your 2014 or later Mac mini. Plus, make the drive being replaced an external for data transfer, backup, and/or additional portable storage.
Everything you need in one package
Immediately ready to assemble and:
  • Backup and store your data with style and confidence.
  • Take your data with you - small enough to keep in a pocket!
  • Easily add additional laptop storage with no AC adapter required.
Examples of how this bus-powered Express bundle can be used in real world situations:
  • Relocate your "home folder" to your Express and have your files with you at home, at work or on the road without the need to synchronize your machines.
  • Clone your current internal SATA hard drive in your laptop to the new drive. Then install the new, larger drive in your laptop and keep the smaller drive in your Express for additional storage space.
  • Keep a copy of your iTunes library on your external drive to play on multiple machines.
  • Have the piece of mind of a complete backup plan. Create a bootable clone of your hard drive at regular intervals so if your computer goes down, your productivity doesn't go down with it. Boot to another computer and keep on working!
Yes, you can do-it-yourself
OWC is committed to your success, so if you need a bit more guidance, we are available Mon-Fri 8AM-8PM and Sat 9AM-4PM with U.S. based technical support by phone or live chat.

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. 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.
