Interesting but consistent with my informal
observations. My Hitachi
enterprise class 4gb hdd are still going strong after multiple power
outages and almost 5 years of 24x7 on time. Granted not much reading
and writing occurs but the fact that they are spinning is probably
the biggest wear and tear on them. Helium drives? Only if you have
the money to replace them yearly and have a RAID 1 set of a RAID 6
volume....
I took a look at my 1TB drive stash. They're branded as Toshiba,
which,
I believe are really Hitachi. So maybe not so bad.
But on those charts, the 3TB Seagate really shows an astonishing failure
rate...
