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 Simply Awesome! April 3, 2016 Rather than wipe and destroy a SATA hard drive that I replaced with a solid-state drive that I purchased from OWC, I saw this as an option to continue using the SATA hard drive. The assembly process was simple, thanks to the comprehensive tutorial. Everything is included here, even the USB cables. As an added benefit, the drive is powered by the USB cable, so no separate power cable is needed. I now have a bootable drive that I can use when I travel. The padded carrying case protects the drive and holds the cable.

Rating: 4/5 Super fast! February 19, 2016 I love this external drive, it has been a power house for me! Being Solid state, I feel it's far more durable for traveling with compared to a conventional drive which has lots of moving parts. It also has very fast read/right speeds, great for on the fly video editing and for transferring and viewing large photo files. The only slight downside is the housing is far larger than it needs to be, adding some unnecessary bulk. But it is very well made.

Rating: 5/5 Great for archiving February 6, 2016 It seems like only a few years ago buying a terabyte external hard drive cost a small fortune. This was on sale at a price I could afford. And it was just what I needed. I determined my laptop was sluggish and showing too many beachballs from a too full hard drive. After copying all my video and music files to the Mercury hard drive and deleting stuff that I didn't need on my laptop then defragging, my laptop finally got it's speed back and no beachballs. I have several of Mercury on the Go hard drives. Love them. It gets power from the USB on my laptop though I did buy a power cable to plug in the wall just in case. it's small, fast, quiet and has a cool blue blinking light that indicates when working and when resting. It really shows up in the dark. Some shareware is included. It also comes with a carry case which holds both the drive and the cable. The case is sturdy and I don't worry about stuffing it in suitcase or computer bag.

Rating: 4/5 solid performance January 21, 2016 As a backup for my digital music collection this is a fine product. I needed capacity and reliability at a reasonable price. I could wish for more transfer speed and perhaps more options for continuing backups, but those are quibbles not major concerns. OWC is a consistently good performer in my experience.

Rating: 5/5 A USB 3.0 drive that works with lots of drives connected! January 14, 2016 I have a couple of backup drives and several other USB peripherals connected through an industrial strength 7-port USB3 25W powered hub connected to my MacBook Pro. Basically all ports are full. I've tried out two other USB drives, and doing a clone from my internal SSD drive to them would inevitably end in errors, even when not connected through the hub! I think OWC's drive came with a better cable... it has shielding rings on both ends. (I tried the cable with a cheaper drive, and it worked.)

Thanks for a problem-free product all around, OWC!!

Rating: 5/5 Speeds up back-ups from MBP greatly January 9, 2016 I have a late '08 MBP 2.53Ghz which I have upgraded with an SSD 480 Gb HD. It has rejuvenated it so much that I needed an external enclosure to place a spare 7200 rpm HD which could be used on both MBP with Firewire 800 & use USB-3 with my new 27" Imac. The Backups from the MBP via Firewire 800 to the 7200 HD is great, compared to my experience in the past with slower HD's. Of course, via USB-3 its faster still. Extremely pleased, gets a little warm but no worries.

Rating: 5/5 Sturdy, no complaints. December 22, 2015 This little drive feels very sturdy, compact yet it sits solidly on a flat surface. Not quite as cheap as some portable drives but this thing feels well worth the quality boost price.

Rating: 5/5 These drives are great December 22, 2015 This is my 4th OWC Mercury and they are flawless. I have one in both laptops I own and now also have started using them externally as backup drives, as they have become so affordable. I don't even consider other drives when I buy.

The On the Go enclosure is very fast to assemble and high quality. I travel some 200 days a year and those enclosures never blink.

I would recommend this item to a friend! This review is from OWC Mercury On-The-Go Pro 2.5" Portable USB 3.0 Enclosure for SATA NoteBook HDs.
