LSI is dead. Compare it to IDE.
virtio-scsi has the highest performance, but it is not supported on all
guests. Compare it to virtio-blk.
This vs. megasas is a good question; both can be compared to AHCI, they
have good performance and have the advantage of compatibility with real
hardware. If this had gone in first, I would probably have rejected
megasas, but this has the advantage of being used in VMware and
VirtualBox. Plus, unlike megasas Don said he'd work on SeaBIOS support,
so it has further merit.
