"We've been reviewing mobile racks recently since I find myself swapping
drives fairly regularly for testing purposes. Swapping drives isn't
something relegated to testers/reviewers however - those who own or
operate server(s) love the ability to change drives at will - especially
if you can hot swap them. There are many power users who manipulate
multiple OS's and like the expansion capability and the portability that
racks provide. Now you can take designs normally found on a server rack
system and bring it to your desktop. Enhance Technology sent us the
ISWAP 4 Channel Internal IDE Hot Swap Storage Subsystem (Backplane) for
review recently. That's a pretty long name if you ask me so we'll just
reference this as the ISWAP 4 Channel. This is a housing assembly that
can hold four 3.5" IDE drives in the space of 3 - 5.25" drive bays and
allow for hot swapping of hard drives in a RAID configuration. Now
granted - not everyone will need this housing assembly. In fact who
needs to be able to hot swap four hard drives? But if you do, then check
out this article."
