ThunderBay 4 mini
16.0TB Professional Grade 4-Drive HDD Thunderbolt 3 Solution

For Mac and Windows PC
Featuring SoftRAID XT
The Perfect Combination of Speed, Size, and Convenience for Permanent Access to Your Data
Big RAID System Performance in a Compact Design
The ThunderBay 4 mini hard drive equipped solution is big on performance and flexibility yet sized about the length of a pencil. The rugged heat-dissipating aluminum enclosure features two Thunderbolt 3 (Thunderbolt 2/Thunderbolt backward compatible) ports for up to 1556MB/s real-world speeds, so you have more than enough bandwidth to handle personal and business backups — all the way up to today's highest resolution audio, photo, and video formats. If you are seeking big RAID performance that's small enough to fit on a desk, in a rack, or on a DIT cart, your wish is now a reality.
A New World of Drive Flexibility
With four hard drive populated bays, you can use the drives independently or combine drives as a RAID with the included SoftRAID setup and management software. The ThunderBay 4 mini is also perfect for repurposing or maximizing bare 2.5-inch HDDs and SSDs you already own.
Expand production capabilities in industry-leading creative platforms like Final Cut X, Avid Pro Tools, Apple Pro Logic, and Adobe Lightroom, edit large images, manage massive photo and audio libraries, store drone videos, use it as a transport drive…whatever the day or project demands, the ThunderBay 4 mini is the perfect workflow solution.
Install or Swap in Minutes
Want to access another drive or expand your storage capacity? Simply open the front panel security lock to access the four individual bays. Drives mount to a tray that slides back in and automatically plugs into a drive connector so you can get back to work in minutes.
Includes SoftRAID XT: Easy and Complete Drive Management
SoftRAID XT is the most powerful, intuitive software RAID utility on the market. Multiple RAID levels let you select the RAID level that fits you or your project’s needs best. If you need maximum volume capacity, optimum drive performance, data protection, or a combination of attributes, SoftRAID has you covered.

Packed with features like drive validation, verification and failure prediction—SoftRAID includes features you simply don’t get with hardware RAID. It’s like having a datacenter on your desktop! From home users looking to protect photos and documents to professionals needing to protect and quickly access projects, SoftRAID is the perfect solution.
  • Compatible: Works with macOS 11 Big Sur, M1 Macs and Windows 10
  • Advanced: Create RAID 0/1/4/5/1+0 (10) with Macs, RAID 0/1 with Windows machines
  • Protected: SoftRAID Monitor constantly watches your disks and alerts you if problems are detected

  • Certified: Checks disks before use to ensure they are safe for data storage
  • Vigilant: Error prediction helps protect against unexpected failure

Verified Buyer
Reviewer: Babysnot
Rating: 4/5 Great Performance but Minor Annoyances October 3, 2021 Very well made and performs as specified, but could definitely be improved. The issues are not deal breakers for me, especially because of the price and overall quality. 1) The fan is a bit noisy. It is always on an runs at one speed only. A variable speed or controllable fan would be a big improvement. 2) The key lock on the access door is a bit over kill for a home office. A little clunky and unattractive. I understand the value of the lock in a workplace, but not at home. 3) The OWC Logo is bright and always on. There is no power switch on the unit. It would be a really nice improvement if this LED would turn off when the system is shut down or when no drives are mounted. I would happily pay a little higher price for these features. Overall I am very pleased with the ThunderBay 4 mini. OWC products are excellent.

Rating: 3/5 Good, but could be better. June 2, 2021 First, let's just get this out of the way: It's not bad for the price. It does what it's supposed to do.

Now a couple of minor gripes (definitely not deal breakers). I traded my big loud legacy Mac Pro for a new M1 Mac mini. The sound level in my office fell to zero, I never knew how much noise my old Mac made until I turned it off. But then I added the ThunderBay mini and my office was silent no more. The fan is not loud, but when you go from zero to some noise, it really stands out. It has a bit of a white noise sound (which some people like, but not me). It would be nice if it was a bit more less noticeable. And with only three SSDs installed at the moment, it seems it would be better if the fan only came on when needed instead of a steady speed all the time (when running, the fan does shut off when sleeping). Or possible a higher quality fan would be quieter. Of course, I'm sure that would add to the cost, but I'd trade up for that.

The second little criticism is the access door. If you are going to hot swap drives often, it would be nicer to have a better access door. As it is now, the door comes completely off with the key lock holding the door onto the enclosure. I do not really need a locking enclosure, so I found this operation a bit clunky. If I was going to swap drives often, a hinged door would be better (another cost factor, I'm sure).

All in all, it works with a few small inconveniences.

Rating: 4/5 Easy setup April 26, 2021 This was my first time setting up a RAID solution and overall, it was fairly simple. I only ran into one issue — out of the box one of the hard drives kept detecting an error. The software prompted me to contact the manufacturer for a replacement. I ended up reformatting the drive and it's been working fine ever since. Very pleased with the product overall though, the drive is very fast... and very quiet.

Rating: 4/5 Well built and reliable, but fan is a tad noisey August 6, 2020 I have this unit working via an Apple TB2<->TB2 adapter with my 2013 Mac Pro trashcan. The computer's silent while the This storage enclosure was making a whooshing sound from the fan. I noticed OWC sold a similar unit that had a switch for the fan. As I'm in an air conditioned studio, I decided to disconnect the fan and monitor the temperature. The unit is now silent, and quite cool.
