yes it is!

just be sure to have good hardware (a bad chasis meant a nightmare for
me once), and cards with good dirvers.

i once had a multiport SATA card with proprietary drivers.  very fast,
very CPU efficient, very stable.... but didn't detect hot-swapped
drives.  IOW: i could change a drive while running, but to detect it,
i had to rmmod/insmod the driver.  aarrgghh!!!
