RAID1 is ok (mirroring) RAID10 is (maybe) better Normally I would use SAS Disks (instead of SATA2). How about RAI10 with SAS ? > 4GB to begin with.. It is ok. Is your OS linux ?

The AMD is maybe cheaper, but hard disks, RAID controller, RAM and a good database design/import scripts are more important. Do you have an server for testing ?
