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).

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***.
