How well does the CRC protection, and busmaster features of Ultra-ATA DMA/33
work..?
Is the CPU utilisation on the same level as SCSI counterparts, nowadays?
(I have used SCSI myself since day #1 :)
If a DMA/33 transfer fails due bad CRC on transmission between host and disk.
Will retransmission be handled by hardware or software to resend?
How well is the CRC feature supported in FreeBSD..?
