NV+ extra disk cacacity..

Looking around I think I should format using Flex Rad RAID 0 rather than X-RAID which is what I have used

If you do RAID 0 there will be no redundancy - i.e. one disk fails and you lose everything. Not recommended IMHO.

I would suggest replacing - one at a time - with 2TB or larger disks. They represent best value at the moment. 250GB is very small today. If you have 1.5 and 1GB I suggest you buy 2x2GB WD RED, that will give you more space and easy expansion.

Thanks for your advice. I regularly back up to external drives so Raid 0 maybe still an option. Il look at the WD red drives.

Thansk again!

If you use RAID-0, the best way is to keep the drives independent (that is, volume C being only drive 1, volume D being only drive 2).

You can do this by doing a factory reset with only 1 drive installed, and then choosing flex-raid. After the initial setup, add a second drive and create a new volume.

You will lose RAID-5 protection of course, and also the automatic expansion feature of XRAID. But if a drive fails, you will still have the data on the other drives.

The downside is that you need to manage the space used on each volume manually (occasionally you will need to move shares around to prevent one drive from getting overly full).

Fantastic thats what I'll do - thanks again

When I'm adding the other drives can I put them in individually while the nas is running or should I switch off first??

You can insert them with the NAS running. That is what I generally do.

Great thanks for all your help

I have removed these and put in a 1.5tb and 1tb. (I also have 2x500gb to add at a later date). I done a factory reset and after the hd’s have initialised it shows only around 927gb of storage available.

The storage is only as big a the smallest like when you hike minus formatting. Its showing the size available expanded to the 1tb size. If you had 2 1.5 it would be that minus formatting.

Doing separate drives is probably the only way to get the full 12 tbs (if you have 4 3 Tb drives) and 6 otherwise. I'm pretty sure though 3 will make the 3rd a scratch drive and make more of a speed difference than drive increase.

BTW those 500GB's probably won't work since the minimum you started with is the 1Tb and the new drives have to greater than or equal to that. I bought bigger drives for my computer and tried to use the 250GB drive I removed and got that error.

Hope that helps.

Thanks for all your help :)
