I forgot to mention in my first post that I'm using ULE. The p800

There's maybe one additional thing: do you dual-boot Linux and FreeBSD?
If so, you'll need to set up a separate additional partition for the
database, instead of benchmarking it with the file systems used by the
OS, because different areas of the drive(s) have different performance -
you can verify this with diskinfo -t.
I installed FreeBSD onto a boot-partition (p400i-controller) and used
the external storage (p800) as database-partition (eight 15K rpm
sas-disks in raid 1+0). Same with Ubuntu. When I re-installed FreeBSD
and ubuntu I wiped and formatted the previous partitions. Ubuntu used
ext3 which I guess is default fs.
Write performance is something that we are working on, expect to hear
about progress over the coming weeks/months.
