This product is constructed of heavy duty metal to hold up in the toughest of conditions. It includes ventilation slots on the front & back for maximum airflow to keep both SATA and SAS drives running cool, and an LED is placed on the front of each drive tray to give the user drive status at all times. Dual 4-pin power connectors are used to ensure a consistent power supply to all four drives, whether they are low power SSD's or power hungry 15,000RPM SAS drives. Also included are dual 40mm cooling fans to keep the drives running in at optimal temperatures in even the most intense applications. This is a device commercially designed for: Medical & Military systems, Media servers, IPCs, HTPC, and All-In-One computers, approved & used by Tier 1 companies.

MB994SP-4S

The MB994SP-4S is constructed of full metal to hold up in the toughest of conditions. It includes ventilation slots on the front and back for maximum airflow to keep your drives running cool, and an LED is placed on the front of each drive tray to give the user drive status at all times. The 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.

MB994SP-4S

The MB994SP-4S utilizes our brand new EZ Slide Mini Trays, making drive interchangeability and maintenance completely hassle free. The trays are built using full metal so that they are durable for many lifetimes, but will not weigh you down when transporting your data from system to system. And featuring a full cage design, the added top drive cover provides added protection while moving the drive. The trays are also designed to accommodate 7mm, 9.5mm, 12.5mm, and 15mm drives giving you the ultimate universal 2.5" hot swap bay.

MB994SP-4S

Utilizing its small form factor, The MB994SP-4S is perfect for use in industrial PCs, servers, or any small form factor case where 5.25" bays are limited and large drive capacity is needed, especially compact RAID 5 systems. It is built to function in the most demanding environments including military and law enforcement deployment, as well as manufacturing conditions such as embedded control systems and factory automation systems. The heavy metal design makes it ideal for placement in rugged environments.

Almost Perfect

Pros: Solid construction. Quiet--Fan noise is audible, but not objectionable, especially compared to most server RAID trays. Great cooling (4 drives run at about 34-37C at 24C ambient). Accommodates chubby drives like WD Velociraptors. SATA connectors work with locking cables. Drive lights show green with power, and flash red with activity.

Cons: WRONG power connectors. Stupidly wrong. Incomprehensibly wrong. Quality Control could be better (I had to re-shape two of the drive trays, which were out of square, to get the screws to line up, but fortunately I've done sheet metal design and fab, so this was no biggie). Not really a con, but you'll need VERY short screws to keep from interfering with the drive trays. The kit includes short screws, but Dell uses special quick-release screws that work with the SMT case, so I had to file down the Dell drive screws to be short enough to use. Also had to file the computer case, because this needs a full 38mm X 145mm opening (not a con, but FYI). Drive lights do NOT shut off or even change color when drive is removed. The outer shell has excessively sharp edges that should be knocked down in fab before painting, but trays themselves are not sharp.

Update: After less than a year of use, the fans both started squealing and slowing down. Since they have separate airflow paths, if one of them had locked, both drives on that side would have been toast, which for a RAID5 would have been unrecoverable. I replaced them with Sunons, which were a little louder (not a big problem in a server closet), but lowered the drive temperature down to 31C, and those have lasted ever since. They could definitely have used better fans.

Other Thoughts: Bought this for a Dell Optiplex 755 I'm making into a server. Two of the trays were not quite square, preventing the screw holes from lining up with the drive, so I had to tweak the cage a bit to get them to fit. Don't know if this was due to QC or damage, so I didn't take off a star. The biggest issue is THE POWER SOCKETS, for which this loses a star. Seriously Icy Dock?? Did you not think that if people are using SATA drives that they'll have SATA POWER PLUGS? The Optiplex 755 has ZERO Molex connectors! Almost all adapters are Molex-->SATA. Almost none are SATA power to a Molex device. The only one I could find that goes that way was the Kingwin SAC-05, which gives 2 Molex from 1 SATA, almost like it was designed to address this mistake. If I-D insist on using archaic Molex power plugs, they should include the adapter. Better to use SATA sockets, for which adapters (Molex-->SATA) are readily available.

Manufacturer Response:
Hello Victor,

Thank you for you're review, and I'm glad you're enjoying your drive cage. I wanted to address a few of the concerns you brought up.

Regarding the use of MOLEX, we do actually have a new model that uses SATA power connectors, the MB607SP-B. Like your model, it features a full-metal enclosure with 4 bays, but uses only a single SATA power connector rather than dual MOLEX.

As to your fan failure, I'm sorry this has happened to you. We design our products, particularly our ToughArmor series, to be as rugged and long-lasting as possible, so I'm sorry to hear the the fan has failed. Your product, as with all ICY DOCK products, is backed by a full 3-year warranty against all defects, and we would be happy to resolve this for you as per the warranty. Please contact us directly at tech@icydock.com to discuss this.

Thank you,
Chris - ICY DOCK Customer Support

Love it!

Pros: Solid build, easy installation.

Cons: None.

Other Thoughts: Perfect solution for me, allows 4 SSDs in a small space without complicating wiring inside my case. Highly recommended if you are running more than 1 SSD.

Great, but could use some improvements..

Pros: No plastic garbage components (fans are okay to be plastic) to worry about. Fan cooled.

Cons: Fans are low quality one bearing top design with bottom bearing being a sleeve. These fans will not give you enough hours or reliable operation before they start to get LOUD from where the rear sleeve bearing in each of them has gone bust. So I had to change them out with fans that I had to order from an electronics component distributor.

Other Thoughts: If you want to remove these fans and put in high quality ones, then use Orion OD4010-12HB fans. These fans are double ball bearing, produce only 25dB of noise, and are guaranteed for 60,000 hours of operation at 45C!!!. You'll have to unsolder the connectors from the original fans and put them onto the new fans. Newegg probably carries 40mm fans of similar quality also. I have not searched to see.

I just wished the manufacturer would have gone with these fans in the first place. Yeah, it would have raised the price to an extra $20 possibly for this product, but at least I know that extra $20 gave me some piece of mind that I bought a bullet proof product that will last me many years.

Ugh

Pros: Metal with a nice powder coat finish.

Cons: Rail screws are only a few threads deep and 3 stripped out from the forces of basic manipulation of the case shortly after installation.

The two 40mm fans are ridiculously loud. Louder than the other 6 120mm fans (Noctua NF-P12/Cougar CF-V12HB) and CPU cooler (Noctua NH-D14) in the case combined. Luckily they can be disconnected from the printed circuit board easily.

Other Thoughts: I'll be replacing it with another brand asap.

Pros: Good use of space, well ventilated, hot swap, takes 4 bare WD velociraptors.

Cons: Difficult to believe that such a small box could be so useful

Other Thoughts: Got mine for under $50

Fantastic use of space.

Pros: • Sturdy, all-metal construction. Keeps things cool, and feels like quality.
• A single 5.25in bay turns into 4 hot-swappable 2.5in drive bays: great if you're low on expansion space, or just have a lot of drives to connect.
• Drive carriages interchangeable with other Icy Dock products, and extras available on NewEgg--see item #N82E16817994125.
• Easy to install, and for me, everything worked as it should out of the box.

Cons: None so far. Maybe slightly quieter fans would be nice, but they don't exactly bother me.

Other Thoughts: Bought two of these (along with its cousin, the 2 x 2.5in + optical bay--see item #N82E16817994146) and couldn't be happier with them. Drives are easy enough to swap, and the metal carriages provide extra protection when outside the computer. Two of these give me eight hot-swappable SATA/SAS bays from only two 5.25in slots--a very efficient use of space for me.

Some other reviewers have noted that they don't see the HDD activity LEDs working. I can confirm that they are there, and they do work, under the correct circumstances. As Icy Dock says in their documentation, the amber activity lights depend upon the disk and controller you use to provide the correct signaling. For example, SATA drives I have used running in Windows don't seem to show any activity lights, but on my SAS controller in BSD, the amber lights start flashing.

Simply Awesome.

Pros: Fits four 2.5" drives in a single 5.25" drive bay.
Has cooling fan built in.
Includes drive cassettes.
Quiet.
FAST.

Cons: Needs two power cables.
Documentation is sparse.
non-raid

Other Thoughts: Easy install, mounted four 256gb SSD in a single bay to attach to a add-in sata card. Copies to drives run at full 6 Mb/sec SATA-3 speed. Requires two power connectors for proper operation, and each drive has individual SATA connection. Drive cassettes slide in and out easily. Contains a cooling fan to keep drives cool.

All in all a great product which met all my expectations and was well worth the money!

icy dock

Pros: great construction.heavy duty.built to last and great for multiple ssd drives.

Cons: this is a follow up review.i have purchased 2 of these now and the only issue's i have are the fans keep getting load after just a few months of use.i blow my tower out bi-monthly to avoid to much build up in fans.they look to be cheap sleeve fans or something else?perhaps a change to 2 ball fans would be a better option.

Other Thoughts: i am ordering my own 2 ball fans,from newegg of course, to replace the 4 fans that now that have become very loud.that is going to cost an additional 45 dollars?icy dock did offer to replace the fans, but i fear it will be the same fans!
