do all commercial nas's now put jbod into a single unit

[sparks]

I have some older nas's that allow each drive to be used individually but now all nas manufactures seem to roll jbod into a single device. Some have said this is because the newer file systems can only give access to one unit.
Still its one goes you don't know whats left, and synology said if its the drive with the os installed you loose it all.

Is there any that allow individual addresses for each drive?

These have been sooo many post that Raid 5 is just an accident waiting to happen I don't think its worth it any more.

volume per disk is one way. JBOD is scary in terms of no backup within the NAS.

RAID is not 'if', but 'when'.
RAID is not a backup!

My Buffalo Linkstation Duo, configured in JBOD, when creating a share, I can choose to put the share into Disk1 or Disk2. This Buffalo is 2 or 3 years old.

Thecus N2200EVO, bought last year, configured in JBOD, have no option when creating share folder. Both Disk is combined into one volume.

Based on Stevech, it seems Synology can seperate two disk into two or more volume.

"I also have the NAS automatically backup its volume 1 (disk 1) to volume 2 (disk 2) every day, using the Time Backup (Synology) so I have the file revisions for many months back. "

Thanks.
