I've got a pair of WD 500gb RE2 drives in my D-Link DNS-323 NAS. It's gigabit and the drives are mirrored. Typically getting 3-6MByte/sec :-( Was getting a bit more when they were not super full... maybe twice that... but still nothing near where the drives or the LAN are capable of. I'm gonna be throwing some 1.5 or 2tb drives into the box soon, probably seagate 1.5tb 7200.11's but I dunno if I wanna spend the money if I can't get some better speed. Anyone have experience with the 323?
