[RndTbl] Linux 4K drive formatting

Well, I upgraded to 12.04 and of course there's no change since the
LSI SAS1068E controller doesn't support drives larger than 2 TB. Sigh.

Can anyone recommend a 2- or 4-port PCIe non-RAID controller that works
under Linux, supports large drives and is affordable?
