Good file system / Hdd layout for linux

[Mick Howe]

I'm insterested I'm peoples opinions regarding suitable file system / Hdd 
layout for linux.

I'm running RedHat 7.1 on a Celeron 533, 640MB ram, 44x CDROM, 2x write/ 
8x read CDR, with two 4.3 SCSI HDDs, currently partitioned as below:-

sda1 - one primary partition 300MB - DOS 6/ Win2K boot - fat16
sda2 - Extended containing
sda5 - 2GB NTFS 5 Win2K system
sda6 - 2GB fat16 used as a dump/storage area

sdb1 - Extended
sdb5 - 2GB Ext2 "/"
sdb6 - 2GB ext2 "/home" used as a download storage area
sdb7 -linux swap

what do others use and why?
