    Standard Mechanism

    Release Candidate (RC) firmware set

    There are two kinds of firmware for SSDs Mass Production (MP) and Release Candidate (RC). Prior to an MP firmware release, there are beta firmware releases and an RC firmware release. Often, the RC is the same as the MP release, however there can be small changes and bug fixes made between the two. OWC has evaluated the RC for the 6Gb/s SandForce 2281 Processor and found it to be stable with no issues reported during our testing. However, as with any evolutionary product, issues may surface as different usages and configurations are employed and it is important to understand that there will be further updates and revisions.

    Since no firmware update is currently offered for the OWC Mercury EXTREME Pro 6G SSD, no update page exists. To see the typical steps involved with a self performed field firmware update, please visit our 3Gb/s product update page at: http://eshop.macsales.com/Customized_Pages/Framework.cfm?page=sf_firmware.html

    It is important to note that the current firmware update tool requires the use of Windows XP/Vista/7. OWC is currently working on a Mac OS based update tool, but we do not have an exact availability date.

    Rating: 4/5 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!

    Rating: 5/5 No more beachballs December 16, 2016 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.

    Rating: 5/5 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.

    Rating: 5/5 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.

    Rating: 5/5 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.

    Rating: 4/5 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.

    Rating: 4/5 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.

    Rating: 5/5 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.

    Rating: 3/5 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.
