I'm waiting on a Sheevaplug, and my long term aim is to use it to replace my current Intel-based file server. This file server uses 4x500GB SATA drives, and as I'd really like to re-use these drives with the Sheevaplug, I've been looking at suitable USB SATA enclosures.
General USB SATA drive enclosures seem mostly to be single drive, although I've found a couple of dual drive enclosures and, most interesting for me, this:http://www.startech.com/item-download/SAT3540U2E-35in-4-Drive-eSATA-USB-Multi-Bay-External-Hard-Drive-Enclosure.aspx
...so that's an enclosure that will take 4 SATA drives and offer them up on a USB interface.
Information seems to be thin on the ground, although there's a manual downloadable from the above - I can find no reviews and (relatively) few distributers, let alone Sheevaplug users. However, it does look like they're available here in the UK for around £116, which isn't too bad if you tot up the cost of 4 single enclosures or 2 duals, and it would make things quite neat.
However...would I be asking for trouble using something esoteric like the above as my file storage in a Sheevaplug based file-server setup?
