Rating: 5/5 Excellent right out of the box October 4, 2016 Easy to set up and use. It's working as well as my first Mercury Elite Pro Dual, which is still going strong after three years. I had questions for tech support about RAID configurations, and they were easy to contact, quick to reply, and really experienced. Another great OWC purchase.

Rating: 5/5 Super Fast Hardware Raid September 11, 2016 I bought one of the and populated it with a pair of WD Blue 4TB drives. I use Reds in my Synologies but OWC tech support said those were problematic with this unit so I took there advice. I have the Mac pro 2013 and it has 6 Thunderbolt ports and I wanted to take advantage of those for the reported speed. I must say that even though I'm using regular HDs (as opposed to SSDs) the Raid Zero speeds are amazing. And it's all handled by the box's hardware NOT software. I liked it so much I bought a second one and populated it with a pair of the WD 5TB Blue drives. I use Synologies to house my finished work but these are for my active photo and video files and the speed increase over the NASs and the external single drives is amazing.

Rating: 4/5 So far so good September 10, 2016 Does exactly what I'd intended it for. Two 4 TB drives that mirror my photo backups onto what seems like 1 4TB drive. Redundancy should one of the drives fail. Fan doesn't seem as noisy as some would think. Depends on how quiet your work environment is I would imagine. Cheers

Rating: 5/5 Terrific big drive for mirrored backup September 1, 2016 Have a 4TB drive with about 10 years worth of my work backed up on it. One day the backup drive didn't want to mount and I got really worried. Turned out to be a dirty USB port on my computer, but I took it as a wake up call. Went to OWC and quickly found this 8TB raid. Set it up for two, 4TB mirrored drives. Now I have two additional copies of my data in one sturdy enclosure.

Setup is easy and can be configured several ways, as with most RAIDS. That said, I must confess that I made a stupid mistake setting it up and was initially confused when it didn't show up on my computer. Called support at OWC. Got a tech on the phone in under a minute. Took him another minute, tops, to talk me through getting it formatted as mirrored drives.

As always, I'm totally satisfied with the product quality, price and speed of shipping I have come to rely on from OWC. Now I have had my first experience with their tech support. It is as impressive as all the other facets of OWC's service. They have long been my go-to for all things Macintosh and will continue to be. Can't say enough good things about them. They offer things that are hard or impossible to find anywhere else, they stand behind everything they sell and provide perfect service in every way.

Thanks again OWC for the great drive, the peace of mind it gives me and the fabulous support.

Rating: 5/5 Ample Storage with a Small Footprint August 19, 2016 This unit was ordered as a Time Machine Backup for a Mac operating under the El Capitan version of the Mac OS. The unit is quiet and operates unobtrusively in the background. It provides us with the Raid 1 mirror imaging we were looking for. We chose this unit because of our positive experience with an OWC 1 TB unit we've been using successfully as another external HD since 2011.

Rating: 4/5 Reliable and Fast, but noisy and lacks off switch June 11, 2016 I'd easily give it 5 stars except for the noise and lack of on/off switch. It may be the drives (Toshiba DT01ACA Series) making the noise, but it is noticeable enough to mention here. Also, if the computer is awake, the drives are running, even if I'm not using them. Again, wouldn't be a problem but if I'm not using them (I use them for video editing only), I'd rather not put up with the noise. Thunderbolt is worth the extra expense. The speed is great.

Rating: 4/5 Solid, but noisy April 25, 2016 This is a pretty decent RAID; the build quality of the case is good, and the unit arrived quickly.

Half a star deducted due to the noise of the fan, and another half star deducted due to the setup process (I'm running it in Raid 1 mode via Thunderbolt). The drive wasn't recognised initially, but I was able to format it successfully in El Cap recovery mode (Cmd-opt-R on reboot). Overall i'm pretty pleased with it.

Rating: 5/5 Superb Hard Drive April 11, 2016 Best hard drive I have ever had. Blazes ahead of all other hard drives I have ever had. I have only one problem and it is an Apple Problem not the hard drive. When I want to start up or do work on the mac, I have to unplug the hard drive at start up. Something in thunderbolt connection messes with the completion of the start up. I read up on it and tried all the solutions but could not get the thunderbolt set up on the mac to re-install the corrected firmware. I decided to wait Apple out. Did not do this at first only after an OS update. Right after the log in screen appears I can plug the hard drive thunderbolt cable back in and it is off to the races.

Rating: 4/5 Everything I Was Looking For, Except For Fan Noise March 29, 2016 This thunderbolt dual enclosure was everything I needed. It supports 2x 8TB drives. The drives automatically spin down on both thunderbolt and USB. However, the fan noise is indeed loud. I'm not sure if my enclosure actually has reduced sound, but the noise is noticeable and annoying. If not for the fan noise, I would give it 5 stars.

Rating: 4/5 Great Enclosure February 7, 2016 I really like the enclosure that OWC products. I have bought several enclosures from them and I'm always satisfy. This particular enclosure was a replacement for a Mercury Elite AL Pro and I do welcome several improvements, my main points are: 1. Better packing. Notice right of the back it was a lot easier to get it out the box and put it back if needed. PERFECT 2. Although the manual explains where the from of the enclosure is, the word "FRONT" engraved or labeled on the closure to put it together would be better. NEEDS IMPROVEMENT. 3.Short Cables. I was quite disappointed about it, they were not longer than a meter. The USB particularly is quite short, half the distance of the ones from the old model, if you need long cables you need to but them separately. 4. A big difference is that this model have the mode selector in the outside not the inside, which is smart, but you will need a small screw driver to select the proper RAID/Span/Independent mode. A selector that does not required tools will be better. NEEDS IMPROVEMENT. 5. Interfaces. The old OWC enclosure I had lasted me so long and with several computers because it had several interfaces FireWire 400/800, USD 2.0 and eSATA. and as I move to better computers this new enclosure will make it easier since it has thunderbolt and USB 3.0 but I would welcome an eSATA connector. GOOD.

Overall is an amazing product and I'm very happy with it.

Rating: 4/5 Slightly Different January 18, 2016 Have purchased a number of these in the USB-FireWire-eSata configuration. Major change with this unit (besides the Thunderbolt-USB 3 interface) is the absence of an On-Off switch. Comes on and goes off as the computer does. No way that I am aware to eject and turn off except to pull out either the power or Thunderbolt cables.

Response from MacSales.com, Technical Support January 21, 2016 The absence of a power button was intentional. When the product was first designed, we followed the existing requirements provided by the chipset reference design. However, as new options become available, we do evaluate our customer feedback for future versions and additional product designs. Thank you for the feedback.

Rating: 5/5 Quality Product January 4, 2016 Ordered the bare enclosure and purchased drives from another vendor. I am using the following drives: Seagate ST4000VN0001 4TB Enterprise NAS HDD with 7200 RPM and 128MB cache. Decided on this drive because it is 7200 RPM, has 128MB cache and is rated for 24/7 with 5 year warranty. Powered up drives initially with default setting of RAID 0 so I could perform speed tests with the higher performance setting. Used QuickBench 4.0.7 with the following results (max:avg:min): read = 385.695MB/sec:375.646MB/sec:360.080MB/sec; write = 354.578MB/sec:345.269MB/sec:285.652MB/sec. Powered off the drive and set it to RAID 1 as I plan to use it and achieved the following results (max:avg:min) read = 215.175MB/sec:197.898MB/sec:171.383MB/sec; write = 216.122MB/sec: 199.786MB/sec:181.049MB/sec. The 216MB/sec value agrees with Seagate's published max sustained data rate of 216MB/sec. Overall I am pleased with the enclosure and happy with my selection of HDDs. I would recommend this enclosure and the HDDs.

Rating: 4/5 Very solid machine, just a little noisy. December 22, 2015 It's very solid, fast and convenient with a strong metal case and single cable operation. My only real complaint is that it's a bit noisy, nothing horrible but noticeable. On top of that, I wish there was a way to keep it plugged in but not have the fan running, even after unmounting the drive. Easy fix to just unplug it but worth noting. Would buy again.
