The drive we used for comparision is the
MPB model of the same density, and make. The most obvious
difference between the two hard drives is the top cover. The MPB sports a
blackened aluminum cover giving it that Darth Vader look, while the MPE
has a shiny stainless steel cover that has benefits not immediatly obvious
from right out of the box.
The MPE also has an impoved EMI shield which covers the full top surface of
the drive, where the older version only shields the actual platters. I won't
talk about what effects this imporvement may have, because I am not too familiar with
EMI shielding issues. But for those who are thinking the stainless steel is
doing the shielding that is not quite correct. Stainless steels are non-magnetic by
nature, which would expain why the material can replace aluminum as the
covering material, but also why a ferric metal plate is still used to shield the
hard drive. Stainess steel is a also more resistant to deformation then aluminum
- but I don't suggest anyone test that out with their drives;-)
|Fujitsu has opted to protect the thin plastic conductor
tape leading to the internal armature on its newest version with a small
aluminum shield. A wise improvement considering I've seen at least one
drive destroyed after having this thin conductor cable cracked by impact
with a CD ROM's edge.
Is that a hard drive or a dying cat in
Well, the MPE is probably the quietest drive I have ever layed my hands on. During the benchmarking I could barely
tell the drive was doing anything - and I had the cover off my case,
and computer sitting next to me! The aluminum cover of the MPB certainly didn't do
much to quiet the movements of that drive, but the new stainless steel case does
it quite well. According to the specs Fujitsu lists, the new cover decreases sound
by about 1 db, giving this drive a sound factor of about 3.4 bels on average.
That is increadibly quiet. Even less then the sound of one hand claping....
