I have a Dell server that was advertised to support 4x3.5 + 2x2.5

actually only install 3 drives because the stock DVD drive
consumes a mobo port.
Yeah T30 PowerEdge. The local shop has the card Dell recommended,
but I'm not sure I trust them since it's unlikely Dell tests
anything but a thousand variants of Windows and *maybe* RedHat.

I'll second the LSI Logic/Avago/Broadcom? SAS/SATA controllers.
They run as many disks as I want at full speed. As previously
mentioned they can be quite inexpensive if you buy one relabelled
as (for instance) an IBM card.
They do need to be flashed to a recent firmware version.
Older firmware versions limit themselves to 32-bit block numbers.
A probably obvious note:
PC type boxes have unfortunate limitations unless one
is prepared to spend $$$ for high end or Xeon/Opteron.
PCI lanes and memory subsystems can saturate :-(
