 Seagate (yep really!), they're enterprise grade drives that have
spent five years sitting in some under-loaded corporate server (nobody
chooses 3.5" SAS for heavy loads) and now have an even more restful
life in my NAS[1]. They were also very cheap - I'm a great believer that the
I in RAID should not be an E. I'll also take second hand enterprise gear
over fancy domestic gear any day.

[1] Yes that is also second hand enterprise gear - it's a supermicro rack
tuned down to be just fast enough to saturate both LAN interfaces serving
NFS from ZFS and decrypting the drives.
