[Backups]

My only real question is why use such small drives?    3 x 2TB provides either 4 or 6 TB of storage (depending on whether you're talking data drives or including parity in that list).    Either of these could be matched by a single 6TB drive (with one more for parity).    Ditto the 2nd box ... the higher capacity drives provide much more storage with fewer drives and fewer SATA ports.

 

I simply don't need bigger drives that's all, I am currently aiming for an 8tb (4x2tb) data unRAID plus 2tb parity & 120gb SSD cache, and a 12tb (4x3tb) freeNAS for backups.

 

My current server data is all held on a single 2tb drive!

[Backups]

I am right in the middle of planning a new home NAS build, primarily for the same as most, movies, pictures etc.

 

My current plan is a Plus licence unRAID box with parity, swap and 'smaller' data drives, lets say 3 x 2tb.

 

Then I was planning a FreeNAS box just using UFS with fewer larger drives, eg 2 x 3tb.

 

This way my unRAID box as a daily NAS has that extra fault tolerance from the extra drives and can sync to the FreeNAS box which is used purely as the backup box with the same (or more) capacity, this allows the backup box not to need any extra licencing with potential for more larger drives for backing up other machines/unRAID's in the future if needed.

 

Any thoughts/warnings on this approach?
