To remove a 2.5" drive from
the 4-bay MB994SP-4SB-1 unit, push in the little metal locking lever to release the catch and pull the
At the back of the unit we find four SATA ports for
each of the drive bays, a molex power connector and fan switch. The metal
back plate is flush with the tops of the four SATA jacks, cables are well
supported and there's little chance of a SATA socket being bent off. Two 40mm
cooling fans draws air from the front and exhaust it into the PC case. The
fans are pretty quiet when running and only turn on when there's a hard drive in one
of the bays. When installed in the case a bright green LED indicates the status of
The steel drive bracket has enough vertical room for 15mm tall
2.5" drives. Although you do need to screw the drive in place from the
bottom, PCSTATS prefers this approach over sliding a bare hard drive into a hard
drive rack. When it comes time to RMA a hard drive, manufacturers like Western
Digital and Seagate are increasingly refusing scratched and marked hard drives. With
the caddy approach the HDD/SSD circuit board is suitably protected as well. At
the front of the metal drive cage are flat stainless steel springs for EMI/RFI
That's about all there is to the ICYDock MB994SP-4SB-1 multi-bay
hard drive module since the device is effectively transparent to the SATA
drives installed in it.
The only issue PCSTATS
encountered while testing the IcyDock MB994SP-4SB-1 was occasionally the engagement between the steel drive caddy and
the aluminum chassis was a bit sticky (the fit is loose). Conversely, when we want
to remove a 2.5" drive, sometimes the catch will stick a bit.
In both cases it wasn't problematic or impossible to
seat correctly in a matter of moments. The IcyDock
MB994SP-4SB-1 looks well made
and is a compact and convenient way to mount four 2.5" SATA hard drives/solid state drives in
one spare 5.25" bay. Given that optical drives are going the way of the
Dodo, it's good to know older PC cases can be upgraded
to keep up with technologies advances. The IcyDock MB994SP-4SB-1 four-bay 2.5-inch SATA hard drive rack
is well worth considering and at $60USD it's not expensive.
