I will have to nuke the system in order to make it
production, but it should be able to saturate GBit/s.
I don't know how many IOPS it would have, but it
is likely to have at least an order of magnitude
better performance than the local RAID 1 pair
of spindles.

I'm expecting about 1 k IOPS, but I haven't measured
that yet.

I don't have a spare slot in the server (it's an old
SunFire X2100 M2) and I wouldn't be able to afford 2 TByte
of SSD in any case.
I think I'll go with an NFS. I have some 3 consumer NAS
which export NFS as well, and I haven't done iSCSI yet
so NFS is definitely simpler to deploy.
