That seems unlikely unless you have significant contingent of really
old drives, such as the 5.25" size that's often a good four inches
high, because 50 drives adding up to 40 litres calls for a mean volume
of 800ml per drive.  What these days passes for a full-size desktop
drive is typically - where's that measuring tape - 2.6cm x 10.2cm x
14.6cm, about 1x4x6 inches, for about 388ml.  I've seen a few 4" drives
that are more like 2" high, which is getting close to 800ml, but unless
you don't have much smaller than that...and that seems unlikely if
you've got U320 drives and the like.

Though, I did once have an HP-IB disk that weighed about half what I do
and took up something like three cubic feet.  It was about half a gig
and, as a friend of mine once remarked upon looking at it (I was living
in Montreal at the time), "when they nuke Montreal it'll be power
failure that takes that drive down" (as opposed to the EMP).  Takes
just one of those to push the mean volume-per-drive quite high. :-)
