You might wonder how much of a good idea it is to have
an easily removable connection, connecting up your harddrive. While the convenience and ease of accessibility is a plus, what kind of connectors are now
responsible for the harddrive properly operating? For instance, what good is having a
removable drive if the connection is shoddy and the drive never works, or data becomes corrupted
through corroded pins, or an improperly seated drive caddy? Thankfully these concerns appear to have been addressed
in a much more through manner than the other removable hard drive rack we've looked
at - the plastic hard drive rack.
With the entire unit made from extruded aluminum, the tolerances are fairly
tight, and a brace at the front of the unit helps to keep it that way. The
manufacturer has also managed to introduce a few subtle features that ensure a proper connection
between the caddy and rack every time.
For instance the connector is an old 50-pin SCSI/printer jack with gold plated connectors to
reduce the concerns associated with corrosion. But what if the caddy isn't pushed all the
way back into the socket you ask?
Well, another feature ensures that this cannot happen. To install the
caddy in the rack, the handle must be up. It is this way
so that a caddy can lock into a cog on the side of the rack's frame.
As the handle is pushed down in the final moments of insertion, the cog kicks in and
forces the caddy to sit properly in the SCSI/printer socket. If the handle is not
down the unit is not properly installed.
