I've had no direct experience with the newer cards I'm afraid so cant
comment. If you go for the 1820 it must be the 1820a which is hardware
raid vs the 1820 which is software.

All the tools for the 1820a work nicely under FreeBSD 6.1 :)

232x has native support but I've never heard of the 2720 not even
mentioned on their site 2220 perhaps? This has a driver for FreeBSD
also including an open source version.

Not really the right question as most cards are only x1 PCI-E cards.
That said I dont know for sure but I suspect they have very similar
