'conventional' IDE/ATA ata(4) driver, as shipped with FreeBSD-4.11
anyway - seems to cover the Sil, most HPT, *claims* to cover most Promise.
That driver is as common as fly poop - it's everywhere.


High Point RocketRAID 18XX & SATA, per FreeBSD 5.3,  want: hptmv(4)
- DragonFlyBSD STABLE doesn't include that, though ata(4) seems to
serve just fine.


The RocketRAID 1820 is a weird piece of hardware for all I've read. It seems to be some mix between software and hardware RAID and all in all probably nothing you really care about (except if you need 8 plain SATA channels on a small piece of PCB).


Promise 'SuperTrak' want: pst(4) - DragonFlyBSD STABLE doesn't include that,
and the Fastrak-150 TX-2 plus are 'invisible'.


That is because Supertraks are a wholly different animal than Fastraks. Supertrak is what people generally call hardware RAID (I know you have your own views about the issue). Supertraks are in the same general area as 3Ware is, i.e. the OS doesn't mess with the generation of the RAID, it doesn't actually see it, either. It's just one big disk to the OS.


As for Sil, talk to FreeBSD's Soren Schmitt (AKA ata guy ;-) about that piece of c***.
