2.5TB with ReadyNAS Duo ?

I own the ReadyNAS duo version that doesn't support HDD above 2TB

My question is : can i use a 2.5TB in this unit and get 2TB of storage space ? I don't expect to get above 2TB capacity but will my unit be able to use the drive or it just won't detect/format it at all ?

If you just install the drive, it will detect much less space than 2 TB. I don't know the amount for 2.5TB drives, but for 3 TB drives it detects something like ~700 GB.

You are better off just getting another 2 TB drive.

Oh i see... it's not worth it then.

I have another ReadyNas Pro with 4x 2TB.... Can i just replace one of the HDD by my 2.5TB, then take the 2TB from it and put it in my ReadyNAS Duo ? Or will it mess the Pro device because there will be 3x 2TB and 1x 2.5TB ?

You can use the 2.5 TB in the pro - it won't mess anything up, but (as you suspect) you won't get any extra space.

The you can put the 2 TB drive in the duo.

Do this with hot-insert (on both devices), then the ReadyNAS will detect the disk insertion and delete any existing partitions.

Re: 2.5TB with ReadyNAS Duo ?

It's a good idea to delete any existing partitions on the 2.5tb drive using your PC before using it in the NAS.
Same applies to the 2 tb drive that you remove. I would first wait to make sure the 2.5 tb drive is accepted and the pro does a successful resync before using the 2 tb drive, just in case you need to put it back into the pro.
If you did want to reinsert the 2 tb drive for some reason, you'd need to do it with the pro off, otherwise it will be wiped.

Back it up. Use UPS.

You shouldn't need to delete existing partitions if you do a hot-insert.

I agree that you should wait until the resync on the pro completes before inserting the 2 TB drive into the duo.

Agree, but some users still seem to have problems:

Re: 2.5TB with ReadyNAS Duo ?

ok i did exactly what you guys said, it took 24 hours to resynch both discs but i'm still limited to 1gb space !!

Raidar does detect two 2TB disk but i don't get more than 1TB, even after rebooting 3 times...

If the resync is complete, try a reboot.
