Query: The penultimate parallel SCSI controller for speed freaks. Connects up to 28 internal/external SCSI devices.

Quality hardware, solidly build. Very fast, 4X PCI-e, beats most of the competition, no question. Largely compatible with mainboards featuring the UEFI fontend. Instructions for updating firmware are a tiny bit difficult to decipher. Works with all Windows operating systems, Macs, and Linux.
