I completely agree and wonder if some have unrealistic expectations.
The WD20EARS is listed as a desktop drive and is cheap - $/GB.
The RE-GP, (if you need the green features, otherwise RE series),
version WD2002FYPS cost more and has the following extra features over
the WD20EARS:
RAFF - vibration handling
TLER - RAID optimised error handling
An MTBF spec and the comment
"Each drive is put through extended burn-in testing with thermal cycling
to ensure reliable operation."
Which presumably helps weed out infant mortality cases. It is also
interesting to note that while all the RE series drives have a spindle
support bearing at both ends, only the 2TB desktop drive does.
In light of all the above, you get what you pay for and need to adjust
expectations accordingly.

Richard
