ThunderBay 4 mini
16.0TB Professional Grade 4-Drive HDD Thunderbolt 2 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 2 (Thunderbolt 10Gb/s backward compatible) ports for up to 1346MB/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.
Highlights
- Four 2.5-inch drive bays
- Up to 1346 MB/s with (2) Thunderbolt 2 ports (Thunderbolt 2/Thunderbolt backward compatible)

Solid - Pro Quality
April 1, 2018
I like the small footprint of the 2.5" disks. I use mine in a configuration of 2 - 1TB WD Blue SSD in a Raid 0 (Striped) for my photo processing (scratch) then move the finished photos to my OWC Mercury Pro Qx2 with 4 - 4TB Seagate NAS in a Raid5 configuration for picture storage. In the remaining two bays I have 2 - 2TB Seagate gaming disks in a Raid 1 (mirror) configuration for my iMac Photos and iTunes files. It performs without fail for the last 1 year. It fits anywhere on my desk or cabinet. I would recommend this item to a friend! This review is from OWC ThunderBay 4 mini RAID Ready Four-Bay External Thunderbolt 2 Storage Enclosure.

Great product, but now dated.
February 7, 2018
This is a fantastic enclosure, and is only slightly dated by the inclusion of Thunderbolt 3 on new Mac models. I've achieved over 1GB/s with this enclosure, and wouldn't hesitate to recommend it if you have Thunderbolt 2 connectors.
It is not whisper quiet, however, and for some media rooms will not be acceptable. I'd be 5 stars if it weren't for the fan noise.

Great Product - Very Quiet!
October 17, 2017
Very quiet which was the main reason I selected this unit over other manufacturers. I was using another thunderbolt unit from another company...but the fan and airflow through the other company's unit made too much noise for my taste. I use SSDs that do not require much cooling as does HDDs, so this unit is perfect for me (though HDDs would work well also with the unit), I work with Video and Audio recording using a Mac Pro 2013, so the ThunderBay 4 mini is perfect for the cost and my usage!

Perfect
July 25, 2017
I have been re-configuring my home network and going through the hardware I had laying around and found a bunch of 2.5" drives. So to re-purpose them, I ordered the OWC Thunderbay 4 Mini. I knew it was going to be the perfect piece of hardware I needed for these drives as I have been a loooong time & satisfied OWC customer and have been ordering all my MAC upgrades from them.
I was quite surprised at the small form factor, sleek looks, and very fast performance. The Thunderbay was easy to load the drives into and it was plug & play to connect to my Mac Mini.

Thunderbay 4 + SoftRAID hits the spot for MacBook Pro External Media
March 12, 2017
I got this product from OWC (Thunderbay 4 mini drive enclosure 0 drive) as a solution to accommodate a number of (new) SSD's into my external drive plan with a single cable as a DAS for fast external access to my photography raw files. I wanted a device that would be capable of very fast throughput for fast read/write performance supporting the fastest transfer rates but also compatible with both what I have now (MBP 2014) and the future machine I hope to get in the next year (2016+ MBP). A singe drive measures over 300Mbps read/write speed, while the RAID 4 array measures 730 Mbps Read and 1,004 Mbps read using AJA System Test Lite and Blackmagic DiskSpeed benchmarks. That is fast enough for most formats of video on my MBP. Your speeds will definitely vary with source machines, drives, and connection methods.
Works on all counts. I can't say enough about the support I got from SoftRAID pre and post sale. I had lot of configuration questions and expectations on configuring the internal four drives and using it as a RAID array with additional partitioning of a drive larger than others.
First, about the OWC Thunderbay's mechanical assembly. It is a very sturdy black painted aluminum case. It stand on four rubber feet and is very quiet when the fan runs, it is practically inaudible in a quiet room. On the front you have a keyed lock, LED's on the front for power, drive access (4) and ventilation holes for the fan powered assembly.
The front panel completely removes with the key. It removes exposing four drive trays that simply plug in to the rear frame. The front panel secures the drives from becoming disconnected with an integral bumper strip.The drives can "hot-swap", however in the case of a RAID array, that will be rather ineffective to yiour operation if a drive is removed for any other reason than replacing it with the same size and rebuilding an array. If you will use the enclosure to house media as formatted as JBOD then hot swap will work for you, just be sure to dismount the drive before removing. The system will need to be reattached to T2 port to mount on your host computer or re-powered. I usually disconnect the power plug after ejecting the drives. Therefore, this hot-swap feature isn't needed and no power switch is provided.
At the rear, you'll find a 72W DC power connection jack requiring the supplied external power pack, two Thunderbolt 2 jacks used to loop between other devices (multiple drives, monitors, etc. Note that this enclosure is Thunderbolt 2 (20Gbps) and is only downward compatible with Thunderbolt 3 (40Gbps).
The drive trays are metal and well grounded to the case for static control. Your drives screw to the tray with four screws each and are supplied. Spares are available but only as a set.
The overall documentation and product quality is very good. This is a good value for the product provided.
I give it a 4 star rating based on my list of pros and cons below. This is a user's review not paid or in any way compensated by the distributor. Would recommend!

With 2.5 million MRI files on a conventional disk using Firewire 800, the repeated seek delays were beyond annoying, despite using a 2013 MacPro and the latest OsirixMD.

I have been happy with my drive enclosure. It is small and nice and quiet. The only negative I have is that it uses too much power.

Good but quite noisy
August 29, 2016
The whole idea of getting an SSD storage array was to get something I can keep on my desk. However, with the Thunderbay 4 mini I cannot do that. The drives are quite but the fan is way too noisy. They rally need a spend a couple more bucks on a quality fan to make this a quality product. What compounds this is that the drives don't sleep when not used but only when the entire computer goes to sleep - which for me only happens at night.
I read others having replaced the fan with a much quieter noctua fan - but unfortunately I could not figure out how to do that.
Highly recommend OWC make a truly quiet device the next time.

In May we moved to a brand new fan solution and reduced/eliminated the noise level from the fan noted. We are always listening to all customer feedback and further working to improve products on an ongoing basis and fan noise was high on the list from the beginning and something that was successfully mitigated with product currently shipping.

This awesome little device works exactly as it is supposed to! I took several old hard drives from previous laptops, reformatted them, and put them into this enclosure. They worked immediately!

Exceeds all expectations
May 26, 2016
For years I have dreamed of having a RAID 5 array for speed and reliability. This fills the bill nicely and its performance exceeds all my expectations. With 7200 RPM HDs the performance easily exceeds the other external drives I have and although I have not had the "opportunity" to test the RAID 5 data recovery capability, I am confident it will perform as advertised.

Goodbye internal drive bays, Hello Thunderbay Mini!
February 29, 2016
I put off moving to a new computer for a long time because I didn't want to lose the 4 drive bays on my trusty Mac Pro 1.1. Finally bit the bullet, if getting a gorgeous 27inch iMac can be called "biting the bullet". Thunderbay Mini to the rescue for my data storage.
I've been putting it, (and SoftRaid) through their paces and so far the performance is admirable. I love the small form factor. I am using 2 units with OBR10 (one big RAID 10) across 8 2TB drives, giving 8TB of highly redundant data storage. A 3rd set of disks will serve as offsite storage, to be swapped with one set of mirrors on a periodic basis. Should keep me for awhile, at least until the next bump in drive sizes.
Only 2 nits to pick. One is the markings for the drive lights are practically invisible. Not that big a deal for such a compact device; you can identify the lights positionally. But still, someone did go to the trouble of specifying and implementing markings. I'm at a loss as to why making them actually be visible did not seem to be a concern.
Second nit is with the associated Soft Raid product. The software has been working quite well, and does its job very efficiently. However there does seem to be a lot of promotion of RAID 5 as a storage strategy. In part due to that, my initial direction was with RAID 5. Upon further research I have run across many warnings that RAID 5 is definitely not recommended for modern drive sizes, and considered a bad option. Research RAID 5 and "URE" (unrecoverable read error). Once you get past a certain disk size it is quite likely that the storage array will ruin itself when attempting to recover after loss of any disk. RAID 10 is considered far safer for your data.
In short, a very valuable product for me, 5 stars but make sure to do your research and carefully consider your RAID storage options before finalizing your decision.

Great enclosure
November 16, 2015
As a working photographer, I'm always on the lookout for faster, quieter storage for terrabytes of data. An all-SSD 4TB RAID 5 setup is still beyond my ability to rationalize, but I recently got the crazy idea to go the Fusion Drive route instead, and it's working beautifully thus far.
I picked up the Thunderbay 4 mini, popped in two 2TB Seagate 2.5" drives and a 480GB SSD and, bar a small setup issue (hint to others: there's no need to buy the RAID5 version of the enclosure if you're going the Fusion Drive route, as SoftRAID won't work with that setup), it has performed exactly as expected. Performance with newly-downloaded photos is lightning-fast, since they get copied to the SSD portion of the Fusion Drive, and if I have to go back to some older data for a job, it usually gets moved to the SSD after a few accesses. My Lightroom catalogs also reside on the SSD pretty much permanently, given how ofter they're accessed. The access lights on the Thunderbay are very helpful in determining which drives are being accessed at any given time.
I'm sure that most will be purchasing this enclosure to create a more standard RAID volume, but I wanted to let prospective purchasers know that it works quite well in a non-standard setup. It was an idea I'd had in my head for a while, and I'm glad I finally pulled the trigger - it has lived up to my expectations, and I wouldn't hesitate to recommend something similar to anyone looking for a brilliant combination of fast access and copious storage in a small, quiet (though not silient) package.

Great value enclosure.
October 12, 2015
Fully loaded with Samsung Pro SSDs, I can verify read speed over 1GB/s using the included SoftRAID driver over a Thunderbolt 2 connection to a Mac Mini.
The enclosure itself is fantastic. I'll ding SoftRAID slightly for not having a driver for El Capitan ready at launch, but the current beta driver has been working fine. This isn't a fault of the enclosure itself, though, and the enclosure works fine with SoftRAID if you want to stick with the standard Apple drivers.

Good performance for the price.
October 10, 2015
I like the ThunderBay 4 Mini SSD RAID box. It is a lot of storage in a small package. The software made it really easy to setup everything. I was able to easily chain in a monitor in TDM. The major benefit with the mini is the power unit is external and that heat is not in the enclosure and it is all very small. The fan is not as "whisper-quiet" as advertised, but it is fairly quiet. If one of your reasons for using SSDs is to avoid noise, the fan might bother you. The overall benefit of the RAID enclosure far outweighs the small noise issues.
Write speeds for four drives in RAID 10 (1+0) were slightly faster than two original Mac SM256E SSDs in RAID 1. Read speeds were about the same with double the drives, but it is still fast enough for my needs so no real complaint about it.

Fast and sturdy, but not silent
September 11, 2015
I'm running four SSDs (Samsung SSD 840 EVO Basic 1 TB) inside my ThunderBay mini, which is connected to a 5K iMac, with an OpenZFS RAID-Z over all drives.
While the enclosure is sturdy and transfers are fast, I'm a bit disappointed about the fan noise. Its fan is rather small, and as such has to spin fast to generate a respectable air flow.
I could disconnect the fan, but I'd most likely lose warranty and would worry about temperatures (though I suspect that in my environment and with SSDs rather than HDDs it might be OK).
Because of the noise there are times I want to switch the unit off, and because it has no power switch one has to disconnect the Thunderbolt cable to do so.
For comparison: I used to have one of OWCs bigger enclosures (for four 3.5" drives; with eSATA, Firewire 800 and USB 2 connectors), which also had some fan noise, however its larger fan would spin slower, generating less noise that could more easily be ignored.
So if you care about noise a lot I'd suggest thinking about this enclosure's bigger sibling, even though it "wastes" a lot of space if you use 2.5" drives with it.

Works perfectly with OS X RAID
July 10, 2015
I bought the 4 TB ThunderBay to work with my Mac Pro (2013) and Thunderbolt 2. I set it up as a striped and mirrored using the standard OS X Disk Utility RAID settings. This ends up with a 2 TB mirrored drive. With Black Magic Disk Speed Test I get about 155 MB/s write and 185 MB/s read. Not too bad for spinning rust on 2.5" drives. For reference I have an older 480 GB OWC Mercury Electra SSD in a USB 3 external case that only gets a little better than that (180 MB/s write & 230 MB/s read).
The 4 1 TB 2.5" drives are temporary until the price of 1 TB SSD comes down in a year or so. The ThunderBay enclosure should be useful long after the drives are obsolete.
If anyone has the same bay with SoftRAID and a similar setup, I would be curious to know what your performance numbers are (Black Magic Disk Speed Test is free on the Mac App store.)

Great storage solution
May 14, 2015
I'm an it guy. This was an inexpensive enterprise grade raid solution for a consumer price. I went with Speed and storage and used 7200 rpm laptop drives. This replaced my LaCie jbod storage. My storage performance went from 70mb per second to about 400mb not as fast as my 900mb raid0 ssd os solution but getting 3tb with the read rate it's worth it. SoftRaid 5 works great. And was worth the extra cost. Looking forward to grabbing an additional one of these storage arrays soon. I would recommend this item to a friend!

Great size efficiency and overall solution mitigated by little annoyances
May 3, 2015
My desk doesn't have a lot of available space, so the ThunderBay 4 mini seemed like a good fit (literally). It's small, fast, accommodates 4 drives and it is optimized for SSDs -- doesn't waste precious volume on accommodating 3.5" form factors. It's metal and feels rock-solid. Comes with a Thunderbolt cable. Works great, and the version with SoftRAID rounds it out for a great RAID 4/5 solution. I liked it a lot, at least until I powered it up.
The downsides are that you end up with an power brick -- I hate external transformers -- and that small fan that all the reviews and product information say is "quiet" really isn't if you have silent SSDs (like the Mercury Electra 6Gs that I also purchased) in it. You have audible low frequencies of air passing through the enclosure. Those don't bother me. However, the MB60201V3-0000-A99 fan (in theory, 23 dBA from OEM spec sheet) used in the enclosure has this soft, high-pitched whine that was distracting to both me and the other occupant of the room it lived in. As much as I'd like to keep it, that's a dealbreaker for it to be used where I need to.
Return RMA is underway, and I'm looking at the full-size ThunderBay 4 RAID edition as a replacement with its lower-RPM fan (20-23 dBA) and internal power supply, as well as its unfortunately much larger size and need to use 3.5"-to-2.5" step-down carriers for my SSDs.

Super fast but noisy
April 17, 2015
It's a super fast SSD RAID. The only drawback is the noises of fans (it's small fan so it has high-freq noises). Luckily you can use a long Thunderbolt cable to put the RAID far away from you. It would be nice if OWC can reduce the fan speed for SSD version. (HDD version is hotter) I would recommend this item to a friend!

After comparing everything I could find in a reasonably compact Thunderbolt 2 drive array to connect to my Mac Pro I finally decided upon the ThunderBay 4 mini in a 4TB configuration. The unit is compact and well built. The fan is audible in a low noise environment, but not at all noticeable in an office.
I've currently opted for using Apple's built-in RAID facility and the drive is performing exactly as expected. Lightning fast and stable. I'm very satisfied with this purchase and would recommend it to anyone looking for a fast and compact DAS solution.
I would recommend this item to a friend! This review is from 4.0TB OWC ThunderBay 4 mini Four-Drive 7200RPM HDD External Thunderbolt 2 Storage Solution.

Does what they say

It's not a complex product. You stick in SSD drives and it works. I was interested because it had a Thunderbolt 2 connection. I've had it for a month or so and had no issues with it. I would recommend it to anyone looking for an external RAID array on a Mac. I would recommend this item to a friend!

The enclosure is awesome
January 12, 2015
but hard drives stink. I've been wanting an enclosure like this for years, so I jumped on it as soon as it was announced. I wanted a fast, quiet, RAID hard drive, and this is all three. I was expecting faster performance than I got, but that's the fault of the four 2TB drives inside. I'm getting about 500MB/s in RAID 0. Once the cost of SSDs decline, then I'll make the switch.

Thunder bay Mini 4 - Outstanding Product
January 3, 2015
Moved from a 2010 Mac Pro to a 2014 MacBook Pro. I delayed the moved because my Mac Pro was maxed out with 4 Disk Drives and I wasn't sure what to do migrating to the MBPro. I knew I could count on OWC and just about the time I was ready to move on the "Thunder Bay 4" the "Thunder Bay 4 mini" was introduced. I called tech support with questions on the mini and it seemed like what I was waiting for. I migrated two existing SSD's (One OWC) for the Mac Pro and bought two more SSD's from OWC to fill up the Thunder Bay mini 4. Mission accomplished!! As a bonus I have the option to boot from the Thunder Bay Mini vis a vie Thunderbolt2 should I choose(Contrary to what Mac Support said and it works, I tried it). The Thunder Bay Mini 4 is Fast, Quiet and Runs Cool. I would recommend this item to a friend! This review is from OWC ThunderBay 4 mini RAID Ready Four-Bay External Thunderbolt 2 Storage Enclosure.

Excellent drive enclosure

I have been using the Thunderbay 4 mini for just under a month now and it works exactly as advertised.
One of the best features is the cooling fan which maintains my SSDs at a comfortable 29° C vs 45° C in Akitio Neutrino Thunder Duo which I previously used.
