Rating: 5/5 Saved my much-loved iMac! July 12, 2018 I was on the verge of getting rid of my old iMac 2011 as a workhorse for editing because it bogged down so easily. I didn't want to take the risk of installing an internal SSD and pulling apart such an old machine, fearing some bits would be more fragile.

I'd looked into external enclosures and carefully researched how much faster a thunderbolt drive would be than the FireWire800 (I already use with a Drobo). However, I use a 2nd monitor and all the small drive solutions were end-of-chain with a single port..

With the Dock I was able to put a 500GB SSD in there AND daisy-chain to my display. My machine is now so fast again I'm not just using it for writing, I effectively got it back as a development machine. I have not had a single hardware purchase deliver such value and relief.

Rating: 5/5 Ability to turn on/off drives independently July 1, 2018 Great dock. Looks and feels pretty solid. I was looking for a external hard drive solution with moving to a laptop from a mac pro and this dock seems to be a great fit for what I was looking for. The ability to have 2 drives on at the same time or individually. This allows me to have two external drives like typical 2 drive enclosures however, I can keep one offline and bring online only when needed to keep my backup safe.

Highly recommend this product.

Rating: 5/5 Excellent Dual Drive Dock! January 22, 2018 I bought this to keep two HDDs running daily and weekly incremental backups of my system, which I then rotate each week, storing them (using the disk storage items previously reviewed) in my fireproof, waterproof, safe. I then replace them with the two new drives and repeat the cycle for the next week. This way I have bootable HDDs for my system with daily and weekly increments allowing me to go back in time as far as needed, along with my Time Machine backups. So I should be fairly safe! I upgraded from the single HDD dock, which worked extremely well for a few years, so I anticipate the same solid performance from this dock.

Reviewer: marka Location: Seattle, WA Age: 55-65 Owned Product: 1-3 months
Rating: 5/5 Fast, easy, reliable. January 11, 2018 I've been using this dual drive dock for nearly a month now. It's fast and performs just as expected. Thunderbolt is an amazing technology and this dock does justice to its incredible speed.

I've used it most of the time with two 12TB drives. I chose this dock because it supports large capacity drives.

The unit is solidly built. The AC adapter is built into the dock so no external AC adapter is needed.

Bear in mind, however, that both hard drives are served through a single interface. This means you won't get the same speeds blazing accessing both drives at once.

I would highly recommend this unit

Rating: 5/5 Outstanding Product October 9, 2017 I really like this dock. It's very well made and works great with my circa 2011 27" iMac. I have used the USB 3.0 only version of the Drive Dock and this Thunderbolt version has a great feature the USB one lacks -- you have to hold the power buttons down for 3 seconds to turn off the power to a particular drive. This prevents accidentally powering off a drive when inserting or removing one -- something I did with the USB-only version. This dock is well-made and just works. Highly recommended.

Rating: 5/5 Excellent Product June 15, 2017 I really enjoy this product. I do a lot of video and photo editing, and that requires using lots of SSDs. I found out that buying SSD/HDD without enclosures to be cheaper than buying an external drive. For that reason, I decided to buy this product. I love it and would definitely consider buying a similar product if it was available with thunderbolt 3.

Rating: 5/5 Outstanding option for data storage May 7, 2017 This past weekend, there was an electronics recycling event in my town. I gathered up my old external hard drives - mostly old raid units with 1 & 2TB drives - and wiped them for recycling. Then I recalled that I had just recently purchased the OWC Thunderbolt 2 Dual Drive Dock for the two 8TB drives I had to backup my archival movie copies, home videos and photos. So I set about disassembling those old Drive enclosures and retrieved the 3.5" SATA drives from each - a grand total of 4 drives equaling 6TB in storage capacity. The remains drive enclosure parts and circuit boards when to the recycler. I then purchased the Newer Tech bare drive static free storage containers, stacked them, and violá, I had significantly increased my flexible storage capability & capacity. I now have 2 8TB, 2 3TB, 2 2TB, and 2 1TB drives. The Thunderbolt 2 connection to my late 2014 27" iMac is super fast and the drives are whisper quit sitting on my desk next to the iMac. The Thunderbolt 2 cable supplied with the dock was just the right length. Overall, this is a superior option for onsite backups. I now do weekly checks on OWC for 3.5" and 2.5" hard drive sales. The ability to buy bare drives at much lower prices than enclosed ones is the major reason I bought the Dual Dock. I am 100% satisfied with my purchase!!

Reviewer: RicM Location: Providence, RI Age: 55-65 Experience Level: Power User Owned Product: over 6 months
Rating: 3/5 Disappointing February 5, 2017 This dock has 2 drive slots but only one SATA controller. I was hoping to use it for super fast transfer between SSD drives in the 2 slots, but because of the single controller I cannot achieve the 500MBS transfer that I expected. I bought this to use on a film shoot where we needed to transfer LARGE amounts of data (1 TB/day at times) for Pro Res HQ video footage. Don't be fooled by claims of how fast the Thunderbolt connection is, it doesn't mean anything if the controller can't handle the bandwidth. The specs on a lot of T-Bolt drive products talk about how fast the bus is without ever mentioning how fast the disk or controller is. The bus speed is irrelevant. The slowest link in the chain is the limiting factor.

Reviewer: BW79ST Location: New York City Age: Over 65 Experience Level: Home User Owned Product: 1-3 months
Rating: 4/5 Works as advertised! February 1, 2017 A Mac is very touchy about moving drives around, as I have found. The Drive Dock is not at fault but if you get one you do have to be very careful about removing drives that may be still spinning. I've corrupted a drive a couple of times when not paying attention to what I was doing so there is a learning curve, or at least there was for me. The drives had been backed up and were easily reformatted so nothing was lost, but I learned to be careful. Sometimes if you leave drives mounted on your desktop and walk away for a long period you will find them dismounted when you return and with a warning to properly dismount them! That is a function of the iMac, and not of the OWC Drive Dock, as far as I'm concerned. A good product but there are caveats.
