Ello Guys,



I just ordered the Synology DS214 play with 2 WD 4tb reds. Should I use the normal config of 1 drive mirrored to the other. I was thinking of going raid 0 and plugging in a 2tb USB 3 drive as redundancy. Would this work or would the 2tb be too small? Any other suggestions? This is my first NAS.

Ta :)

Depends on the how valuable the data you are storing on it is really.

Personally I would go for mirrored mode to have that level of redundancy, in any case a 2TB USB backup drive would not be big enough to backup everything anyway, you would need a 4TB/8TB (RAID1/RAID0) to do that.

Personal opinion is that it's pointless going RAID 0 in a NAS unless you're looking at something that simultaneously serving many tens of users (I assume you're not). RAID 0 is all for performance at the sacrifice of reliability, and you'll not exceed single drive performance limits over a network, let alone RAID 0.

The issue with RAID 0 is that if one drive fails you lose ALL of your data. If you want the benefit of 8TB of storage then configure them as JBOD (I think the Synology stuff allows that), as at least you'll only lose data on one drive if it fails.

Personally I use my NAS as a backup drive, and therefore have my 2 x 3TB drives configured in RAID 1 for the security this brings.
 
Oops, one of the drives wasn't clicked in properly. Its currently expanding the volume to 2nd drive. Gonna take about 8ish hours. Why does it have to copy every block and not just the used space to the mirror drive? Sorry but haven't used RAID before.

Because block for block they have to be identical so if a drive fails you still have a carbon copy so to speak of your data.
