Rating: 5/5 I now buy drives only from OWC June 17, 2016 I bought this to clone laptop drive via SuperDuper and previously a 2Tb one for Time Machine. I bought a 750GB one in 2011 to clone another laptop. I also own two Elite Pros to backup an iMac and all five drives have performed admirably for me. Spare yourself poor quality and frequent failures and shop OWC.

Rating: 4/5 Good product but cable too short June 13, 2016 This portable hard drive works well, efficiently , and quietly as part of my backup strategy. I trust OWC products from long experience with them.

Unfortunately there is one disappointment. The FireWire connection cable that came with the hard drive is much too short to be truly useful. It is difficult to use it with my iMac and reach the drive sitting on my desk near the computer. OWC should provide a longer cable for this product.

Other than that. it's a fine product.

Rating: 4/5 Silent and easy setup. May 30, 2016 A small. silent and cool running unit. Using it as a redundant backup drive for my OWC Elite Pro Dual 6Tb which houses all the work files freed from my 1Tb 2010 iMac. Lots of open space left on all the hard drives now. It lacks a Thunderbolt port so it cannot connect directly to the Elite Pro Dual and has to be routed by my iMac via USB2 for slower than desired backups. As a photographer, I leave it always connected for frequent backups of work in progress.The OWC tech person said that should not be a concern. The resiliency of the clear plastic housing is a concern. The large bright LED is annoying.

Rating: 5/5 So surprised at the speed! May 15, 2016 I knew what to expect with the body, the weight and the sturdiness of this drive, but I had no idea of how good the speed would be. With previous 500 OWC Mercury On-The-Go USB drives, I always had dependability in making a clone of my internal hard drive, but the process usually took an hour, at least. The first few times I used this new drive, I was convinced that something was wrong...the entire process takes less than 10 minutes! It's wonderful! Totally worth the extra cost and I am totally happy and satisfied with the performance of the device.

Rating: 5/5 More than I needed, but glad I have it! April 21, 2016 Now that OWC explained the DIY SSD's to me, I purchased this case not realizing I really didn't need portability, but that I did need the option of USB 3.0 & FireWire. So this was a good move. Like all the products I've purchased from OWC so far, no glitches, no issues, the OWC Mercury On-The-Go Portable 2.5" FW800/USB3.0 went straight to work.

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.
