XFS on them. My possibilities are: (I need total space more than 500Gb)
1. JBOD, each disk one partition
(drawback: I have to take care of not filling either of them)
This will be difficult to manage.
2. RAID-0, one single 1Tb XFS partition
This means if you lose one disk (or even temporarily lose access to one
disk) your entire filesystem is unusable. If all this data is easily
regeneratable from elsewhere this might be acceptable for you.
3. RAID-5
The best choice, gives you 750GB usable space and protection against a
single disk failure.
The most flexible solution will be to add a third component to the mix,
that being a volume manager of some type (LVM2 or EVMS). If you make a
single RAID-5 of 750GB, then use LVM2 on top of it, you can carve it up
into whatever size slices you like and even increase slices at a later
time (if you have free space left or add more disks). I use
3ware+LVM2+XFS and am very happy with the combination.
