Rating: 4/5 Excellent JBOD/RAID Enclosure May 25, 2014 I have this setup with 4 x 2TB Toshiba HDDs in Software RAID0. Disappointed that OWC doesn't have a hardware RAID enclosure with thunderbolt, hope that's in the pipeline.

Despite not having hardware RAID, the performance from the Software RAID0 is extraordinarily good, achieving over 720MB/sec read & 690MB/sec write (using BlackMagic Disk Speed Test)

Rating: 5/5 Thunderbay IV good unit April 28, 2014 I received this unit to use with my 2013 i7 iMac. I have 6 WD Enterprise drives/ This unit holds 4 of them. I have 2 of the drives in a RAID 0 config (Softraid) and the other 2 as JBOD. The unit is plenty fast with 4 drives in RAID 0. It gives big bang for the buck. and the power supply is internal. No external bricks. It does use 4 individual data channels to get this fast performance. But BE WARNED, this is not in the manual. If you run Windows via Bootcamp, (I run Win 7) and this device is plugged into your thunderbolt port, you WILL NOT be able to get Windows to boot. If you run another external box that uses 3 data channels then no problem. But 4 and it's not gonna work. If you have a Mac w/Thunderbolt 2 not a problem. Thunderbolt 1 and there's this limitation.Good product other than that misgiving. They said they would change their advertising to state this .... Soon all Macs will be thunderbolt 2. Let me repeat, this limitation is only if you run Windows via bootcamp. (parallels I don't know?) But it works great on the Mac side of things.

Rating: 5/5 Fantastic Box April 28, 2014 Fill this up with big SSD's and you will love it. It works perfectly and is much quieter than I thought it would be. Very low fan noise, so low, I can't hear it and that's what I wanted. I got so tired of listening to loud spinning hard drives and the fan to cool them. This box with SSD's is not only fast with Raid 0 but is quiet too. It is so nice.

Rating: 5/5 Flawless operation March 27, 2014 I used the ThunderBay IV to migrate two hard drives from my 2006 MacPro (1.1 version) and added a 3TB and 4TB Toshiba drive. The larger of the Toshiba drives is being utilized for Time Machine. This arrangement has worked very well in conjunction with the new Mac Pro (2013.) I have placed my iTunes library on the smaller of the Toshiba drives and there is no apparent latency in playback. The fan is rather quiet. The quality of the enclosure is very robust.

Excellent product and very pleased with its function. Highly recommended.

Rating: 5/5 Just what I've been waiting for March 11, 2014 Not many people I know are familiar with the Netgear ReadyNAS NV+ V2(the system before my ThunderBay IV). I got that system a while back but there was always one thing about it that bothered me. It was soooooooooooooo slow! I kept looking for something with similar features but with a speed boost, possibly one to take advantage of my unused (until now) Thunderbolt ports. Leave it to my good friends at OWC to not only offer EXACTLY what I wanted at a comparable price, but to also give me the option to use my already purchased HDDs from my previous ReadyNAS. Most of the other companies selling comparable products don't give the consumer that option. I've had this for a good month now and it's still going strong. I'm streaming movies, using it for Time Machine backups and all through the Thunderbolt ports. I love it!

Thanks OWC!

Rating: 4/5 Fast and Noisy March 5, 2014 The Thunderbay is very well build! It's very fast, but i'm now thinking of how to get rid of the blowing sound of the TBay. After buying the Mac Pro 6core i needed to bring back my capacity of storage, and the TBay did that PERFECT! But it also brought back the same Decibels as my old Mac Pro 2009 ..

Now i need a 7 meter Thunderbolt cable in white to fix that, which isn't easy to get! If there was a 100$ option to fix that i would have given the ThunderBay iV a 5 star rating!

ps. Service of OWC is AWESOME! I had a problem with one HDD bay inside the Thunderbay, i send in a photo of the problem and i had a new bay within 4 days send to The Netherlands!

.... get it! If you need the space, but also get a very long Thunderbolt cable! I need to find one in white of 7 meters... If anyone knows something :D ...

Rating: 4/5 A well made product February 26, 2014 I am using the device as a RAID 0 array for backup storage and temporary files. It performs well and is extremely quiet in operation. Data throughput is extremely fast for an external unit, far exceeding the firewire 800 units I have used in the past. Like all Thunderbolt units it is a little pricey.

Rating: 5/5 It's a speed demon February 26, 2014 I just upgraded my office computer to the new Mac Pro and was forced to upgrade my RAID. After looking at Pegasus 2 and LaCie products I decided I just needed the fastest possible RAID 0 setup possible. I checked out all of the speed benchmarks and it looked like the Thunderbay was winning. I purchased it with 8 TB of storage and I'm getting between 700-725 Mb/s on Read and Write speeds. Couldn't be happier at this point. No sleep issues or ejection problems in Mavericks. If I had the cash I'd quickly buy another for backup.

Rating: 4/5 This product is well built and fast! February 11, 2014 The first thing I noticed as I was unboxing this unit was the excellent build quality of the unit. The aluminum enclosure is heavy gauge, the drive sleds are easy to pop in and out and feel very solid when in place. I did receive a unit with a cross threaded quick release screw but it still works well. I striped 4 7200rpm seagate barracuda drives and ran Blackmagic Disk Speed Test. I was able to get sustained read and write scores that hovered between 550-600Mbs! I found this very impressive for only using medium quality drives in the enclosure. I can only imagine the speed I would get with Raptors or ssds. The fan is a bit noisy but not terrible and it moves a lot of air through the machine making me feel safe about keeping those disks cool. I have it on a daisy chain with another TB drive and everything works great. I do wish there was the ability for hardware raid on the unit but for the money, this enclosure gave me the best bang for my buck considering that I already owned all those drives.
