NAS Advice

I'm looking for a cheapish decent NAS to store music and photos on. It'll also be used for the occasional backup when I need the space.

I'd basically like to know if the one in the links below is "OK".

Dual HDD Networked Attached Storage (SATA) - SVP
NAS Vista Compatible Dual SATA Network HDD Bay - Aria Technology

I'm planning on getting two ~200GB SATA drives and putting them in RAID 1. Music and photos will then be streamed to PCs using wired and wireless options, as well as possibly a wireless internet radio in the future.

Is there anything that this doesn't have that might be quite useful?

there both the same anyway. more likely that will use the same chipset. they should be good enough for what you want to use them for
