ToughArmor MB994SP-4SB-1 4x2.5" SATA HDD Hot Swap Mobile Rack

Overview

Introducing the Icy Dock ToughArmor MB994SP-4SB-1 Full Metal Quad Bay 2.5" SATA 6Gbps Hard Drive/SSD Hot Swap Mobile Rack Cage for use in a single 5.25" device bay. The MB994SP-4SB-1 is predicated off the incredibly popular MB994SP-4S, while taking its general concept but, with a SATA only interface and adding the fan power switch. In addition, there is only one 4-pin power connector that will reduce the amount of cables required. The MB994SP-4SB-1 allows for many more users to use this backplane in their homes with the reduced cost. The dual 40mm cooling fans to in addition to the power switch for the fans allow for the best flexibility – Turn off when using SSD's and on when using mechanical SATA hard drives. Furthermore, this device utilizes Active Power Technology, so that the device only power up if there are drives installed.

MB994SP-4SB-1

The MB994SP-4SB-1 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-4SB-1

The MB994SP-4SB-1 utilizes our 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 9.5mm, 12.5mm & 15mm drives giving you the ultimate universal 2.5" hot swap bay.

MB994SP-4SB-1

Utilizing its small form factor, the MB994SP-4SB-1 is perfect for use in gaming PCs, small form factor cases where 5.25" bays are limited and large drive capacity or SSD's are needed. This also will benefit 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.

Great But Wish 2/6/2020 7:22:13 AM

Pros: I have about a half a dozen of these docks ...... and it has saved me a few times. It also makes it easy to clone a drive which I have done a bunch of times.

Cons: The only thing is I wish they would give me more screws to mount the drive, Or to remount the plate on the tray. Trying to find those screws is impossible.

Overall Review: Good Product just bought another one.....

Almost Perfect 5/5/2019 1:03:43 PM

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.

Overall Review: 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,

Perfect application for SAS SSDs 2/13/2019 1:38:48 PM

Pros: Loads up to 8x 2.5" SATA or SAS SSDs or HDDs (no more than 7mm tall). Has a pair of HD Mini SAS connectors (SFF-8643) to make cabling easier. The drive trays are all metal and are quite durable for their size and construction.

Cons: The mounting screws for the outer cage seem to interfere with the inner trays such that the trays may not slide cleanly. Use short screws if you can. Due to the form factor, drives are limited to 7mm height.

Overall Review: I use this with an LSI 9300-8i HBA in my rather compact workstation tower so I can fit a bunch of 1TB SSDs in a single 5.25" bay. This unit will require an 8-port (or more) HBA or RAID card with appropriate connectors and cables (or a "reverse breakout" cable to work with onboard SATA connectors) since it doesn't have the usual batch of SATA style connectors.

I like this one better then it's plastic cousin. 11/2/2018 1:10:31 AM

Pros: The slides for this unit work quite well.
This unit is perfect for SSD drives.

Cons: I have not found any cons yet.
I am a little worried about how long the fan will last and if I will be able to find a replacement if it dies.
I will have to keep an eye on the fan to be sure that it doesn't stop working.
It would be nice to have some kind of LED or something showing that the fan is working.

Overall Review: Overall I think I like this unit.
You do have to be sure to use the screws provided as other screws will be too long.

Great idea, cheap cooling solution 9/21/2018 8:48:31 AM

Pros: Very efficient use of a 5.25" bay. Drives slide in and out with ease.

Cons: The fan is NOISY. Even on low it makes an obnoxious amount of noise, and the fan header is INTERNAL, rather than external like some of their other units. This means if you want to replace it with a quiet fan (like the Noctua 40mm), you have to void your warranty. Minus 2 eggs for that.

Overall Review: Aside from the fan issue, it's a good unit. Just wish they put the fan header on the outside or used a quality fan.

Hello Ryan,

I'm sorry you've had this problem with your product. The fans on this model are generally considered quite quiet, and noise complaints are rare, so if the noise is an issue for you, it is likely caused by a defect in the fan. 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. The fan on this model can be replaced by removing the back cover of the unit, which will not void your warranty as long as it is reinstalled again properly.

Please contact us at tech@icydock.com, our experienced tech agents will assist you in creating an RMA claim and getting this fan issue solved for you ASAP.

Solidly built, good for home use drive array 9/16/2018 1:18:48 PM

Pros: Full metal construction.
Drive power and activity indicators through cleverly designed in light pipes.
Lockable to prevent unauthorized drive removal.

Cons: Small fans are LOUD.
Can be easily described with one word - "airplane". Promptly disconnected as there is plenty of air movement in my system.
Spare drive trays are very pricey.

Overall Review: Consider buying small, super-quiet replacement fans as replacements, not a lot of airflow is required for many drives.
.. or just disconnect the fans.

excellent design, terrible 40x10mm 3pin fan; reverse it and use orings as rubber spacers reduces noise 5/22/2018 6:37:29 AM

Pros: Excellent design in all ways, but the (replaceable) fan.

Cons: even on the low fan setting its easily the most grating noise from a computer in the room because of the bad fan it comes with. Fan is easy to swap though, and quieter even if you just reverse it. I used some bits of rubber to isolate the sound of the fan from the metal a bit, which definitely helped.

Manufacturer Response:
Hello,

I'm sorry you've had this issue with your fan. Fan complaints with this model are uncommon, and usually if the noise is a problem it is caused by a damaged fan. Please ensure that your fan is not being hitting wires or anything else, and that there is no dust / dirt around the fan. If these issues are not leading to the fan noise, then it may be that your fan needs to be replaced. This model, as with all our products, is backed by a full 3-year warranty against all defects, and we can repair or replace the fan for you as per the warranty. We can be reached directly at tech@icydock.com

Nice But! 5/14/2018 9:36:49 PM

Pros: Metal construction. Solid build. Locking.

Cons: One star for cost., very pricey, and very noisy fans. I recently had to remove one due to excessive noise. 40x10 Noctua fans are $14 each to add insult to the high price. I don't think fans are really necessary for ssd's but...

Overall Review: I think the price is too high for what it is. I would definitely pass on buying it but I already have one in a previous build so I want same one so I can swap media ssd's between my two computers.
