I do not have a statistically valid sample, but in my desktop machines (I
have had three, but the oldest one has been donated to the deserving poor)
had some of each.

The oldest came with a 1.6 GByte Western Digital Caviar IDE drive. About 18
months later, I added a 4.3 GByte Western Digital Caviar IDE drive to put
Red Hat Linux 5.0 on it. The 1.3 drive was still running 7 years later, but
the 4.3 quit after about 5 years.

The next machine came with two 10,000rpm SCSI hard drives in early 1990.
They are still in there running fine 5 years later. A year or so ago, I took
a slightly used (by me) Maxtor 80GByte Diamond Max 9 drive and put it in
there too. I have never been able to get one of these Diamond Max 9 drives
to pass the Linux badblocks test, even when right out of the box. But they
seem to run OK. Makes me nervous, though.

This machine has 4 SCSI hard drives and two of those Maxtor 80GByte Diamond
Max 9 hard drives. But since I first powered it up in about March 2004,
there are not enough hours on it to conclude anything. One of the Diamond
Max 9 hard drives got two errors:

SMART Error Log Version: 1
ATA Error Count: 2
DCR = Device Control Register
FR = Features Register
SC = Sector Count Register
SN = Sector Number Register
CL = Cylinder Low Register
CH = Cylinder High Register
D/H = Device/Head Register
CR = Content written to Command Register
ER = Error register
STA = Status register
Timestamp is seconds since the previous disk power-on.
Note: timestamp "wraps" after 2^32 msec = 49.710 days.

Error 2 occurred at disk power-on lifetime: 2715 hours
When the command that caused the error occurred, the device was in an
unknown state.
After command completion occurred, registers were:
ER:40 SC:07 SN:3e CL:cb CH:91 D/H:e1 ST:51
Sequence of commands leading to the command that caused the error were:
DCR FR SC SN CL CH D/H CR Timestamp
08 00 08 3e cb 91 e1 c8 1407214.384
08 00 08 a8 b7 db e4 ca 1407214.368
08 00 10 98 b7 db e4 ca 1407214.368
08 00 08 68 fa eb e4 ca 1407214.368
08 00 08 90 b7 db e4 ca 1407214.368

Error 1 occurred at disk power-on lifetime: 2715 hours
When the command that caused the error occurred, the device was in an
unknown state.
After command completion occurred, registers were:
ER:40 SC:07 SN:3e CL:cb CH:91 D/H:e1 ST:51
Sequence of commands leading to the command that caused the error were:
DCR FR SC SN CL CH D/H CR Timestamp
08 00 08 3e cb 91 e1 c8 1407212.992
08 00 08 16 9e 91 e1 c8 1407212.992
08 00 08 06 9e 91 e1 c8 1407212.992
08 00 08 f6 9d 91 e1 c8 1407212.992
08 00 20 ae 8d 91 e1 c8 1407212.992

But that was long ago, and it seems OK now.
