I wouldn't mind spending an extra $50 on the controller IF I knew it
supported 48 or 64 bit LBA, however neither the documentation on Intel
and NewEgg specifies what is supported. In fact I have to assume
PCI-E 1.0 since it doesn't specify (not that it's an issue, 8 lane 1x
vs 4 lane 2x is more or less the same thing; though 4x is more future
proof since there is likely to be a slot that big on future
motherboards at /least/ for physics GPU support).
Are you suggesting the LSI based Intel card because you know it to
properly support >32 bit LBA?
