 Re: SCSI vs SATA hard disks

Out of curiosity, I did some calculations based on the SMART data
for Power_On_Hours on a couple of my PATA drives:
Drive A (ST380013A):
ID# ATTRIBUTE_NAME VALUE WORST THRESH TYPE UPDATED RAW_VALUE
9 Power_On_Hours 058 058 000 Old_age Always 36796
Looks like 36796 hours might be 42% (100 - 58) of expected life.
(36796 / .42) = 87610 hours, or 10.00 years
Drive B (ST3500630A):
ID# ATTRIBUTE_NAME VALUE WORST THRESH TYPE UPDATED RAW_VALUE
9 Power_On_Hours 092 092 000 Old_age Always 7078
(7078 / .08) = 88475 hours, or 10.10 years
Surprisingly consistent, and strictly "FWIW", which might be not much
since I'm making an assumption about the unknown conversion from raw
to normalized values.
