SoftRAID provides a level of performance that you simply can’t get with hardware RAID. Learn more about the power of SoftRAID XT.
The RAID 5 Advantage
RAID 5 merges the four drives inside ThunderBay together for exponential performance gains over a single drive, the combined capacity of three of the drives, and data redundancy that allows the array to still work even if one drive were to fail!
Certified and Tested
Each ThunderBay 4 solution undergoes OWC's multi-hour drive "burn-in" performance certification procedure prior to shipping. This ensures your ThunderBay 4 arrives operating properly, ready for demanding use.
4 drive bays plus so much more. Time-tested Cooling
Built on OWC's time-tested enclosure cooling technology, ThunderBay 4 utilizes an open "flow-thru" vented design with an oversized 92 mm, low-turbulence, noise-quieting fan to keep the drives running cool and reliably.
Multi-Drive
Daisy-chain up to six ThunderBays for massive storage capabilities and increased performance, or connect multiple ThunderBays to multiple Thunderbolt 2 ports to achieve exponential speed capabilities.
Vibration Dampened
ThunderBay 4's drive isolating design reduces sonic resonance, and is aided by over-sized, rugged, vibration-absorbing, non-skid feet.
DisplayPort 1.2 Support
Dual Thunderbolt 2 ports let you connect the display of your choice that your computer can support, including 4K displays.

Rating: 5/5 Nothing short of amazing! June 11, 2021 From the get go, OWC raised the bar so high. I had previously purchased HD drives from WD and another company and it was quite traumatic because I am a beginner at dealing with advanced HD and their customer service/support is definitely not helpful. The HD I had previously purchased from others, came up with error messages on the second day and I sent them back. With OWC, it was a breeze, first of all I am SO grateful for the excellent customer support and then the HD is so fast and reliable and I am able to finally archive my files without any problems. I am going to get some more drives for sure and planning to be a loyal and returning customer!

Rating: 5/5 Awesome Machine! August 3, 2020 I’m really impressed with the quality and performance of this unit. I have loved my Drobos for years but I worry about the long term and I was looking for alternatives. This Thunderbay really fits the bill. I loaded it with 4 WD Reds (the good ones) and am now using it as my Plex server. It’s much faster than the Drobo of course and am thinking of getting another one as a backup for my media. Highly recommended!

Rating: 5/5 Powerful & deceptively easy to setup November 27, 2017 Need storage? This is the unit for your Mac. You know GOOD & WELL you are not using your Thunderbolt ports to their full advantage. [Yes, I'm talking to you!] Securely packaged, the setup was quick and simple. Connected to the iMac popped in drives (I'm using 4 6Tb Seagate drives) and read the SoftRaid number off of the unit, installed and let it do its thing. You basically have 18TB of storage and a hot spare to work with (in user language, not techspeak) It is fast, comprehensive and quiet. I operate this unit in my bedroom and I can't hear it at night. A heavy durable metal unit that looks and feels like it will last you for more than the life of your computer. Next upgrade will be to 12Tb units to triple my storage. I had a mini-cluster of WD drives I had been storing data on that I moved to this unit after one flaked on me. Now I have open USB ports and my data is much more secure. And best of all, the price of the software was included in the drive, saving my $172 on getting it separately. Nicely done, MacSales. Nicely Done.

Reviewer: RAR35
Rating: 4/5 Product working great, but... October 31, 2017 Getting there was a little difficult. I purchased this (along with one HDD) to set up immediately as a JBOD, (using 3 existing HDD's), with the idea that I would put it into service down the line as a RAID. Plans changed, I needed a RAID right away, and I ordered three more 4TB HDD's from MacSales. I used Softraid to set up the RAID, but 3 of the (all new) failed to certification. I sent an email to OWD support to figure out what to do. After nearly a week of no response, I sent another email complaining, and I finally got a response, although by then I had tried again on the certification and all drives passed. Now I'm noticing that my trial on Softraid is running out. It seems like if you buy a RAID, that management software shouldn't cost an extra $150.00.

Response from OWC, Call Center November 9, 2017 Hello! With the RAID 5 Solution ThunderBay, SoftRAID for ThunderBay is included with the purchase price. The serial number for activation should be listed on the underside of the ThunderBay itself. If you do need assistance locating or activating SoftRAID, please contact us at 1-800-275-4576 and we will be happy to help!

Rating: 5/5 Exactly what I needed October 25, 2017 My old pair of 2TB drives in a RAID1 setup was full but I wanted to get something faster. SSDs would have been prohibitively expensive for the volume I wanted and this drive was/is an excellent compromise. In use it feels at least 2-3 times quicker than my old RAID1 pair, which is plenty good enough for my home uses. Setup was very simple and completed within minutes. The thing that took me the longest was locating the sticker with the key for the Soft Raid software (on the bottom of the drive case - duh!). Only other thing to mention is that for my 2017 iMac I needed to get a Thunderbolt 2 to Thunderbolt 3 converter - $50 from Apple.

Reviewer: DesertNomad
Rating: 5/5 Very impressed. Feels like a solid product. May 8, 2017 I am a software developer working with video. I have two older 8TB (4TBx2) Guardian Maximus drives which are on a FW800 connection. I also have another Guardian Maximum that is 4TB (2TBx2). I replaced the 4TB drive with a ThunderBay 16TB.

It came with the drives already installed (unlike some earlier reports here). It was setup as a RAID 5 but I was easily able to reformat it as a RAID 10 (1+0). It is super fast and the SoftRAID software is very easy to use and work with.

I will likely end up buying another one of these as my storage systems are modernized.

Rating: 4/5 Nice to have a lot of storage for everything March 27, 2017 I used to have 11TB of internal storage in my old Mac Pro. Since Apple doesn't like to support that kind of thing anymore I felt this Thunderbay 4 was my best option. Has great features for protecting data and is relatively fast. My only reason for not giving it 5 stars is that the fans are a bit louder than I expected. So this ThunderBay makes more fan noise than my 2008 Mac Pro. I am very happy with the product.

Rating: 4/5 Big, Powerful, and Fast February 5, 2017 Easy to setup with SoftRaid, and although I was reluctant at first to use a software RAID instead of a hardware controller, so far this device has functioned very well. I am using it for the edit of a feature film (8.5 TB of data) as a (12TB) RAID 0 for speed, backing it up nightly to a slower 9TB OWC RAID5 over USB3 for security using the included Data Backup 3, also a very good product. I like the internal power supply (no wall wart). It would have been nice to have at least one alternative bus connection, like a USB3.

Rating: 5/5 Simple and reliable January 2, 2017 I've owned this drive for 1 1/2 years, populated with 4 x 4TB. Upon receiving the enclosure, I installed my 4 drives, installed Soft Raid, configured RAID 5, and haven't thought about it since (other than a Soft Raid update). Thunderbolt performance is very good, as expected. In my opinion, this is how storage should work; set it up and forget it, until the RAID systems starts complaining about a drive. It's so nice when things just work.

Rating: 4/5 For the Price, You Can't Go Far Wrong November 18, 2016 This unit could not have been easier to setup and to use.

It is truly a plug and play unit, if you want a RAID 5 setup.

However I wanted to use the RAID 1+0 configuration. It came all setup as a RAID 5. There was a bit of setup to download the software and reconfigure the RAID.

So far it have been quiet and reliable.

Rating: 5/5 Just about perfect November 17, 2016 I set this up as a 12TB RAID 5 system connected to my OWC Thunderbolt 2 Dock. This allows me to put two 24" monitors on my MacBook Pro. Extremely quiet and super fast using the supplied SoftRaid software. An excellent solution for using my MBP as a desktop but with the ability to pull out two Thunderbolt cables and the power cable and be on my way. I love this thing.

Rating: 5/5 Lightning fast, trivial set-up October 27, 2016 This thing totally flies with its Thunderbolt 2 connection. Unit is shipped preconfigured for RAID-5, but of course to actually use it the SoftRaid driver has to be installed onto the connected host Mac. Software installation was effortless, with the minor exception of having to install an update that was released by SoftRaid subsequent to OWC's preloading of the bundled installer onto the volume prior to shipment. Using the SoftRaid driver to work with the 4 drives as a single RAID-5 volume seems to add very little CPU overhead. I love this thing. I hate being locked into a particular vendor's chassis to support the RAID-5 as would be the case with any hardware RAID. But I do like this chassis, since it is ruggedly built and doesn't need an unwieldy external power brick. Fault tolerance would be even more awesome if I used this together with a second chassis with the same drive configuration so that I could configure it as a RAID-10 volume. Then if a drive failed (or even if multiple drives failed -- as long as the failures aren't on the "wrong" drives), or an entire chassis failed, my data would still be protected. Unfortunately, I can't afford another chassis yet.

Rating: 5/5 Looking for RAID 5 solution? Look no further July 31, 2016 I've been using this 4 bay raid enclosure for about 6 weeks now. I bought the enclosure without drives as I already had four 2TB Hitachi hard drives. Installation was quick and easy. Being it was the RAID 5 Solution, it came with SoftRAID software which is very easy to use. If you are looking for a RAID 5 solution look no furture as this is inexpensive and works splendidly.
