Rating: 5/5 have maybe 15-20 of these OTG enclosures; LOVE 'em! December 21, 2016 Compact. EASY to use. EASY to install/insert 2.5" hard-disks in 'em. RELIABLE. VERY portable!

I've been buying and using these OTG units - sometimes with a disk already in 'em; sometimes (like these three) empty - which allows me to insert my own disks in 'em ... including disks that I get from OWC when they're available at ESPECIALLY EXCELLENT DISCOUNTS.

Donno what else I can say - other than maybe to note that I've been a computer pro since the late '69s (an antiquitarian! :-), and am NOTORIOUSLY PICKY about my hardware (and software - which isn't of concern for this enclosure).

Rating: 5/5 Infinitely better than other USB-powered drives December 11, 2016 Between huge apps and client files, the 500GB SSD on my MacBook Pro was maxed out. So, I took to carrying all client files on a small external 2TB drive made by Toshiba, and leaving only apps on the laptop itself The Toshiba drive was very convenient to carry on a trip, and was inexpensive. Trouble is, it stopped working after a few months, in the middle of a trip, leaving my client files inaccessible. I was not pleased.

So, I purchased a OWC Mercury On-The-Go Pro 2TB drive. It was considerably more expensive than most of the pocket-sized USB drives on the market, and it is substantially larger, making transport a little more problematic. But, I have three of these OWC USB drives, and so far, they have been utterly reliable. I will trade that for smaller size and for saving a few bucks any day.

Rating: 5/5 Like a new Mac November 23, 2016 Using the Mercury OTG SSD as the boot drive for a late-2014 Mac Mini with a HDD. Got the 1TB size to hold all applications, pictures, music, etc. The system is now blazing fast, and I can't detect any difference between this home setup and the Mini with internal SSD that I have at work. The internal HDD is now the TimeMachine drive.

One thing is that the plastic case seems to amplify the blue activity light, which matters in the evening when there aren't a lot of lights turned on. I put a piece of electrical tape on the case in front of the light, and that helps somewhat. If there's a way to turn off the light, I haven't found it.

Reviewer: OldWorldComputing
Rating: 4/5 you may need the AC adapter November 20, 2016 I have several of these drive enclosures. They're very handy for tossing in the laptop bag. I also use them for rotating off-site backups. My only complaint is that, with some drives, they may require more power than is provided by USB or Firewire, which means you have to carry one of the AC adapter wall-warts AND be near a power outlet. This reduces the portability considerably. This drawback is barely implied by a tiny footnote on the product page, and is more explicit in the documentation that comes with the product. I suggest you buy one of the AC adapters and keep it with the unit, at least until you're sure the drive works reliably without it.

(I encountered the problem with HGST 1TB drives; some work without the AC adapter, some don't. Frustrating, especially until I figured out what the problem was.)

Rating: 5/5 Solid drive, flexible, portable solution November 3, 2016 This is my primary on-site backup drive. All my OWC drives, SSD or otherwise, have been very reliable. I recommend them over any other brand except Apple—and they are generally less expensive than Apple branded products.

I particularly like the drive enclosure. Very sturdy, well designed and made. The built in connection flexibility makes connection to almost anything easy, without adapters. The power switch is a nice touch, too.

Only downsides to this package are the took kit, which is kind of chintzy, though the little pry tool is very handy for getting components out of a laptop. The carrying case is well made, but the inner partition (to separate cables and drive enclosure) is too floppy and unnecessary considering the near impervious drive enclosure.

Rating: 5/5 Great Drive July 24, 2016 I'm a bit late reviewing this drive, which I've now been using for 5 years. I bought it for a clone backup, and I've got a few other drives like this one (all less than 1 TB, though). Never a failure, just a great little backup drive and I'm 100% satisfied with this line. It fits perfectly in my bank safe deposit box, also can be carried with me when necessary. Very small footprint. My favorite backup drive.

Rating: 5/5 TimeMachine Drive Replacement July 23, 2016 I bought this drive to replace the 2TB external drive (not an OWC product) TimeMachine drive that Drive Genius told me was failing after only 5 months! I like that the new drive has an on/off switch since I am backing up a MBP that isn't always connected to the TimeMachine drive. As an aside, no drive lasts forever so I'm happy to have another quality drive case for when the inevitable happens.
