[zfs-discuss] Seagate announces enterprise SSD

2009-12-08 Thread Richard Elling

FYI,
Seagate has announced a new enterprise SSD.  The specs appear
to be competitive:
+ 2.5 form factor
+ 5 year warranty
+ power loss protection
+ 0.44% annual failure rate (AFR) (2M hours MTBF, IMHO too low :-)
+ UER 1e-16 (new), 1e-15 (5 years)
+ 30,000/25,000 4 KB read IOPS (peak/aligned zero offset)
+ 30,000/10,500 4 KB write IOPS (peak/aligned zero offset)

IIRC, last figures are for 200GB model, with write performance
degrading by a factor of two for 100  (another 1/2) 50GB models.
Parallelization, or rather lack of it.

Andrey
