We use ZFS and use SSDs for both the log device and
L2ARC. All disks
and SSDs are behind a 3ware with BBU in single disk
mode.
Out of curiosity why do you put your log on SSD? Log is all sequential IOs, an
area in which SSD is not any faster than HDD. So I'd think putting log on SSD

The sequential writes-graphs consistently put several SSD's at twice the
performance of the VelociRaptor 300GB 10k rpm disk and that's a test

The common knowledge you based that comment on, may
actually not be very up-to-date anymore. Current
consumer-grade SSD's can achieve up to 200MB/sec when
writing sequentially and they can probably do that a lot
more consistent than a hard disk.
Have a look here:
