Conventional wisdom turned on its head.
Hardware RAID has long been thought to be superior to software RAID, but we've now combined the massive performance and capacity of ThunderBay 4 with a robust, proven software RAID engine to provide breathtaking performance, flexibility, and reliability.
Software RAID + ThunderBay = WHOA!
Over a year ago, OWC partnered with SoftRAID to bring enhanced storage capabilities to the Mac, and we're now seeing that dream become a reality. SoftRAID 5 for ThunderBay combines advanced RAID modes, fast performance, monitoring, e-mail notification, and fast rebuild capabilities that only software RAID can deliver.
Monitoring + Notifications
Software RAID easily lets you setup drive monitoring and e-mail notifications to keep you informed about your ThunderBay's performance and drive health. Helping you to maintain mission critical workflows.
Better than Hardware RAID Performance
ThunderBay 4 and the SoftRAID engine offers faster performance than many competing 4 or even 5-bay hardware RAID external drives – benefiting from modern processors that are both fast and designed for exceptionally high-performance RAID management with no real-world impact on apps or tasks.
Flexible + Robust
SoftRAID 5 for ThunderBay is extremely flexible and can easily be updated, reconfigured and used across multiple enclosures to provide an amazing amount of robust options to empower you to make the most of your ThunderBay workflow.
Backed by OWC

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.

Reviewer: Apple4Work Location: Austin TX Age: 55-65 Experience Level: IT Professional Owned Product: 1-3 months
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 SoftRAID 5 at a Great Price April 5, 2016 Some have said it is noisy. It is NOT. In my opinion the fan could be larger, but is keeps the unit cool and the only time I am aware there is a fan is when the unit has to be shutdown and it makes a whine as it spins down. The SoftRaid just works. I was skeptical, but not any more. The "proper" setup takes some time to verify your drives, but found a bad drive for me before I had the unit in service. I would definitely buy it again. The cherry on the top is Thunderbolt. Fast, Fast, Fast!

Rating: 5/5 I am impressed! April 2, 2016 I upgraded my Mac Pro 5,1 to a 6,1 3.5 GHz 6-Core Intel Xeon E5. My old Mac Pro had a Sapphire 7950 video card, 32gb ram and an 1TB OWC Aura PCI SSD and internally ran a 16tb 4 disk raid using Soft Raid 5,

It is always a pain to manually transfer data from one computer to a new computer but I was up for the challenge. What intrigued and surprised me the most was thinking I was going to purchase the OWC ThunderBay 4 RAID and install the 4 drives from my old Mac Pro (they are only weeks old) into the new enclosure and have to format the drives as a RAID again and then copy all my data to the new RAID. However, when I installed the drives and booted my computer it recognized the 4 disk as the raid it was in my old Mac nullifying the need to copy the data. This made me very happy! Simply installing my old RAID Disks into the enclosure and Soft raid recognized the old RAID.

I was super impressed with the performance compared to the performance I got in old Mac Pro with the same drives and driver. The read write speeds are incredible. I don't have numbers to show, only that it was very noticeable in my everyday usage. In the future I will purchase another one of these drive enclosures.

BTW: MacSales/OWC has been my go to company for a few years now and they are the best. Support is wonderful and their products are very reliable. I have no problem buying new technologies from OWC .

Keep up the great work....

Rating: 4/5 Great RAID Solution February 21, 2016 I'm a professional landscape photographer. If I'm not out in the field (literally) I'm immersed within Photoshop digitally processing and/or archiving photo files. Having access to a RAID system which provides both ample storage space and great speed is a must.

I highly recommend the Thunderbolt RAID systems. Overall performance is very impressive.

I was also particularly pleased that OWC made the installation/setup of this RAID system quick and easy by pre-installing each individual drive to its RAID housing unit.

The reason I do not give it 5 stars out of 5 is simply because of one factor: noise. This noise pertains directly to the RAID case – the enclosure itself. After a short period of time of use it started rattling. The rattling is not "loud," per se, but it does become quickly irritating. I have therefore ordered an extended cable and will be storing the unit as far from the computer terminal as possible. (If you press down upon the unit with a bit of force the rattling immediately stops. The case itself, therefore, needs to be redesigned to prevent this rattling.)

Rating: 5/5 Fast and reliable! February 13, 2016 I've been using my ThunderBay 4 for about 14 months now with four Hitachi DeskStar 4TB drives in RAID 5 for 12TB of usable drive space. It has been fast and absolutely rock solid with my 2011 MacBook Pro. No annoying random dismounts. I'm very pleased. If I had any complaints, it would be that the fan is a bit louder than I expected, and I had to buy an extra long Thunderbolt cable to be able to keep this under the guest bed on the far side of my home office so that the noise isn't distracting. Otherwise, it's very well built and has worked flawlessly for over a year. Here's to many more!

Rating: 5/5 Very impressed December 20, 2015 I purchased the Thunderbay 4 RAID 5 edition and i've very happy with it. I bought 4 x 5TB drives with it so in RAID 5 i have 15TB of total storage which is actually a massive amount compared to trying to work with a single internal drive. People complained about it being noisy but i don't hear much more than a light fan spinning and it doesn't bother me at all. The best part of all is that Backblaze recognises it as a drive that can form part of your backup so i still have my second level of backup (the first being the RAID) which is a relief. It's pricey, but when compared to everything else on the market it's actually very well priced. I would definitely recommend it to anyone who needs more storage space. Important to mention that i work in video and animation (Premiere and After Effects)
