... these are network storage drives, the World edition, for eg, is accessed as a CIFS share. Supposed to be an embedded linux device - so you should have no problems, provided you can mount the share. Some windows people found that it wasn't compatible with their networks.
You have a 1TiB and 500GiB options (RAID0 and RAID1) - RAID0 makes the overall drive less reliable, and, when one drive fails, you lose all
your data. RAID1 provides a pseudo-backup in that you don't lose your data when only one drive fails.
You can probably get cheaper high capacity using software RAID5 (or RAID15) with a lot of second hand drives.
