Anybody using a 2TB+ USB Hard Drive for external backup?

Correct. Larger capacity drives than 2TB will only work on x86 ReadyNAS (e.g. NVX, Ultra, Pro). This is true for both internal and external disks.

Just to confirm, does that mean that for a x86 ReadyNAS running 4.2.16 or newer (and thus supporting 3TB+ drives internally) they will do USB backup to them fine?

Thinking of buying a 4TB USB drive... either a Seagate GoFlex Desk 4TB or Hitachi 4TB Touro Desk Pro.

I don't have any drives greater than 2TB in capacity. Maybe someone else could comment. I would certainly suggest giving it a try on the latest firmware.

I have a WD Elements 3TB (2794GB) connected to a Pro Business 4.2.21 - works fine.

I have a Seagate BackupPlus 4TB USB drive connected to my NVX and it seems to work fine - just blow away the backup software and other crap on it and format it as Ext4, works just great. My Bluray player is streaming from it just fine, even though it is lowly USB 2.0 on the NVX.
