I have a 80 GB Seagate SATA II disk, and recently I have bought a 250 GB Seagate SATA II disk. I wonder if I could setup RAID 0 with the maximum amount available - 80 + 80 = 160 GB and reuse 170 GB left for storage purpose. Does JBOD matter in this case ? What about Software RAID with Dynamic Disks ?
