Rating: 5/5 Best Product of Its Kind April 22, 2018 These little drive enclosures are the best I've ever used. Strong, sturdy and durable to the extreme. Provides superb shock protection for even "old-fashioned" mechanical hard drives. They cost a little more than a lot of other enclosures, but they're worth every penny. And they look so good! I plan to buy more as gifts for my kids and grandkids.

Rating: 5/5 Great backup and archive solution December 30, 2017 Grandson used his MacBook Pro with Retina for two and a half years of college. His small solid state drive was nearly full and cooling fan was running regularly. He had no external drive and no backup plan! This drive was a great solution at a very reasonable cost. Created two partitions, archive and backup. We moved seldom used files to archive and set up Time Machine for backups. This simple addition will keep his 8 gig, 120 Gig SSD MacBook relevant for the foreseeable future at a very reasonable cost. Thank you Macsales!

Rating: 5/5 LOVE these pocket-sized multi-terabyte storage units December 16, 2017 I've been using these OWC On-The-Go external drives since at least 2012, and love 'em! Have [at least] 18 of 'em - 500GB to 2TB; most USB2/USB3; some Firewire400-800/USB2or3. Something like 20-30 TERAbytes in total. Got most of 'em with the mass-store already inside, but also got a few 0GB cases and stuffed my own drives in 'em (usually extracted from obsolete computers on the way to recycling). Nightly backups (using wun'erful Carbon Copy Cloner); off-site back-ups; easy sharing of monster-sized files; etc. [Well okay - so maybe it has to be a slightly largeish pocket. :-) ]

Rating: 5/5 Compact/Fast July 5, 2017 A nice little portable package, that's faster than most portable HDs. One potential issue I've had is with connecting it to a hub. It "clicks" and won't fire up when attached to one of my powered USB 3 hubs. It must be a power issue as the drive works great when connected directly to the MacPro and Powerbook. Could be a hub issue, though other peripherals are working, so I'm not sure it's that the drive's power requirements are a bit steeper than the hub can handle.

For a first time purchase, it may be an act of faith. However, on installing the disk and reasembling, one is totally reassured as to its robustness, the more so when copying files. It performs well.

Rating: 5/5 Works great, but... June 4, 2017 I purchased this 0GB enclosure when we came to the conclusion that my older 1GB On-The-Go-Pro hard drive enclosure had failed while the hard drive itself was in good condition. The diagnosis of MacSales Support proved to be correct and I now have a functioning external hard drive. However, the latest version of the 0GB enclosure is slightly different that the original and the included instructions are directed toward a newer SSDs. My advice is to contact OWC/MacSales for help if you're installing an older mechanical hard drive in this enclosure. Other than that, the new enclosure performs flawlessly.

Rating: 5/5 Small, Light, Convenient & Reliable April 2, 2017 This is the second Mercury On-The-Go Pro that I've purchased from OWC/MacSales.com. I use them for clone backups of our two MacBook Pro's, usually weekly, to supplement the normal hourly Time Machine backups to other external drives (Mercury Elite Pro's or MiniStacks). We've been using the older On-The-Go Pro for over 5 years now. These drives are light weight and easily transportable along with a laptop computer's other necessary gear. Being USB bus powered (the older one is powered through the FireWire 800 connection) you don't have to lug around an additional power brick.

Rating: 5/5 SSD & USB3 • Go for it ! February 1, 2017 Bought this enclosure & Crucial M500 1TB SSD. This is my music drive for my recording studio. It has OS X installed with Logic Pro X, Komplete11, and all my other plug-ins. Using USB3 on this enclosure with the Crucial SSD, I startup on the drive and can record twenty or more tracks of all varieties in Logic. Latency is very good with my prior Apogee FW interface, and excellent with my new Focusrite Thunderbolt interface. My 13" 2016 MacBook Pro w/ 16GB RAM, chokes with a few hefty plug-ins running, so I simply freeze tracks, and all is well. This config has worked great for the last two years. Obviously, the new MBpros with USB-C are changing things, as USB-C externals will be all that much faster & reliable.

Bought the exact same setup for my beats writing, musician son. He's had two years of glitch free hard use with his setup too ! One caveat I learned. Be careful when doing remote sessions that the external drive & wire don't disconnect. If you must record remotely, keep the drive and the mac on a very solid, not movable surface, or area. If the drive or wire are moved in a way that disconnects, even for the shortest of moments, your drive and its content face the chance of corruption & a crash.

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.
