"Sh*t" really only begins to describe this. So let me get this
correctly: your Hitachi hdds weren't mounted in a very stable manner to
the mobo chassis and vibrations from the fan caused them to fail writes
and retry a _lot_ leading to the write performance drop?
And the WD ones don't have a problem with the vibrations?
Wow! Looks like some idiot was saving on production material/design to
make the drives cheaper. Talk about a major serious FAIL.
