ToughArmor MB996SP-6SB - Six 2.5" SATA HDD Hot Swap Mobile Rack
The 5.25" device bay has been a long standard in computer history. It started with legacy industrial PC cases in the the '90s, all the way to today's Micro ATX cases. The 5.25" bay has been widely used for optical drives such as DVD and Blue-ray, or with even a single 3.5" hard drive with mobile rack. However, it was almost impossible to use a single 5.25" bay to create complex RAID storage - that is, without the MB996SP-6SB Full Metal 6 x 2.5" SATA Hard Drive & SSD Backplane. This is a device commercially designed for Medical & Military systems, Media servers, IPCs, HTPCs, and All-In-One computers, and it's approved & used by Tier 1 companies.
High Capacity RAID Storage in Limited Space
Utilizing the standard 5.25" bay form factor, the compact design allows the enclosure to be used in various applications, catering to a wide audience. The MB996SP-6SB excels for use in advanced RAID applications such as building dual RAID 5 arrays or high performance 4 drives in RAID 0 plus RAID 1 array for back up, all in a single 5.25" device bay. The MB996SP-6SB is extremely useful for powerful small servers, gaming rigs, home servers or HTPC's due to its high capacity and space saving design. It is also perfect for users who needs non-RAID JBOD storage and save different contents in different drive locations. It supports wide-range of applications which is the true value of the MB996SP-6SB.

Rock Solid Construction
Making sure your drives or expensive SSDs are in good hands and last as long as possible is carefully considered in any build or design. The MB996SP-6SB is capable of holding up in various environments, with its heavy-duty, full-metal construction throughout the entirety of the body and its components. ToughArmor's full-metal design is also perfect for industrial and medical devices that may require a flammability rating as the full metal material is considered to already comply with flammability requirements.
The metal material used grants heat dissipation transfer from the hard drives to the backplane cage. Lastly, Anti-Vibration Technology (AVT) and EMI grounding are used to ensure a stable environment for the hard drives or SSD's used, dramatically improving reliability.

Absolute Control of Your 2.5" Hard Drive or SSD
Bringing more utility your hard drives or SSDs, LED's are installed into the front of the mobile rack to provide individual drive status information at all times. Active Power Technology (APT) allows each LED and the cooling fan to be active only when a hard drive is inserted into the same bay of the enclosure.
A 40mm cooling fan is placed directly at the center of the rear panel, providing equivalent airflow throughout the entire cage. Depending on your needs, you may need the fan to be at a higher speed, or completely off for silent operation, and so a 3-Mode Fan Speed Control has been added to flexible in various situations.


Using the EZ Slide Micro trays makes drive interchangeability and maintenance completely hassle free. For drive security, the Eagle-hook lock system on the tray makes sure your hard drives will not eject when not needed. The trays are also designed to accommodate 7mm to 9.5mm height hard drive and SSD, creating a 2.5" hot swap bay for any standard SATA hard drives and SSDs.

With various systems to accommodate, dual 4-pin to 15-pin power adapters are included to fully accommodate all users.

Pros: Nice all metal construction and this is the locking version so you can't accidently push the front tab and eject the drives. Install was simple and it fit 5.25" slot perfectly. I'm using this with 4 Samsung 850 EVO 1TB drives in raid 0 to have a 4TB drive used for a number of VMware VM's that are doing continuous builds for software development.
Cons: This would be a GREAT unit if it had good fans - but alas - they put in lower quality fans. Combo ball / sleeve bearing and they are simply not quiet at all. If you have this in a rack system where you don't care about noise - then the noise is not much of an issue but from the sounds I am starting to hear - I don't think the lifespan of these is that great. Come on Icy Dock - for something like this unit - users will pay the extra $10 to have better fans - heck I have $1800 in drives installed so I would pay a bit more to have high quality fans that are not so loud. I ended up purchasing from Digi-Key a couple of OD4010-12LB fans and putting them in myself (and thus voiding the warranty but I'm ok with that). Much better - virtually quiet.
Overall Review: The locking mechanism is not for security - it is just to prevent accidental removal of a drive. Anyone with the smallest of tools or a key could force the tab open (bending the tab and making that tray unusable) so consider what your application is. But this is better than other units that have plastic locks. Again - if it came with better fans - 5 eggs. If you don't need heavy usage then consider this 4 eggs. But the fans supplied are simply not up for 24/7. The ones I replaced it with are rated for about 7 years of 24/7 usage but I did have to do some simple soldering - which to me is no big deal.
