I smell old Windows information. I believe almost any device can be formatted as one partition and mounted to LINUX. Physical partitions are just a pain. JFS is nice, where you can dole out space as needed. However, disk is very cheap now, so do not set yourself up for a life as a spoon feeder! Advanced virtual FS also support striping and RAID, so you can multiply your device speed.
