at under $30, the addonics ADSA2  is inexpensive. as long as you use
the drivers/scsi/sata_sil.c at or newer than "0.54" (~Jun 16 01:18)
which is when it became reliable for me.
I typically get the high side of 41 to 52 Mb/sec and I've heard of a
stripped software raid getting 100 Mb/sec.
that one has two channels, other models have more, how many pci slots do
you have? Might be worthwhile to price out FlashDisk  too.
