Be prepared to do a lot of testing.  The Coraid SRX may be a good choice
(we have a few of those) but there are many to choose from.  Dell
EqualLogic iSCSI enclosures also work well.

Your results may depend as much or more on what drives you choose than
the enclosure.  10K SATA disks might give you the most bang for the
buck, 15K SAS should give you more performance.  Depending on how much
capacity you need, SSD might also be a good choice.

Don't take any vendor's word for it.  See if you can get a few on loan
and perform your disk benchmarks before you buy.
