I'm doing a lot of work with Microsoft Access. About three different databases ranging from 500MB to 1.5GB. Lots of queries (both reads and writes). My Mirrored setup (Seagate ST3160023AS) is helping with reads, but I need better write performance. I'm looking to set up 4 SATA drives on my Dell Dimension 8400 which has built-in Intel RAID. Can any recommend a good performing and reliable drive? I don't need a lot of storage as I already have a network file server (ReadyNAS) for that.
