I am using two of the 500GB RE3s (WD5002ABYS-01B1B) in RAID 0. They are fast, quiet, cool and not corrupting my data.
I am using an Athlon 64 3000+, 1GB RAM, Dlink DGE-530T PCI Gigabit NIC, Linksys WRT310N w/DD-WRT (gigabit with no Jumbo Frames). I can read and write files @ 16.xx MB/s when testing with Intel's NASPT. FYI, I get the same results with the stock Linksys firmware.
