That is on par with a 5400 rpm disk, except for the 100x more small, random
read iops. The biggest issue is the pricing, which will become
interestingly
competitive for mortals this year.
$600+ for a 32 GB device isn't exactly competitive, though the low-power and
random access are attractive.
Look at previous SSD offerings. $600 is a steal. ;)
From a ZFS perspective, I wouldn't be very excited about 35 MB/sec write
speeds (though again, the random access is attractive). Of course,
considering it's a 32 GB device, you could stripe ten of them, to get a 320
GB flash disk which could write at 350 MB/sec for $6000
Could be nice for laptops eventually, but the relatively small capacity is a
problem for the consumer space (except maybe at the low end).
SSD is not intended for the consumer space, which is sad, as I'd love to run
that
sort of thing at home. ;)
Prices will come down, but slowly. It's that whole supply and demand thing.
People
who run larger DBs are willing to shell out several grand for what seems like a
small
amount of disk space just to tweak DB performance. That will keep prices up.
