NAS Hard Drive replacement

Hosting
#1

Hey folks, I've been using a Synology 2 bay DS220+ along with two six-TB Western Digital Red WD60EFZX drives. I have them set up in Raid 0, because it's really just not that critical if I lose all my recordings, and I'd rather have more space than redundancy. Had them in place four a little over four years.

Well, now one of the drives seems to be failing (twice now in a month it's gone into "read only mode" because of errors, and Synology is beeping at me).

I feel like the cleanest thing is to replace both drives with new ones, since if one is wearing out the other probably is too. I'll probably also upgrade the size (to 10TB each) since the price seems reasonable and can never have too much space.

Anyway, any recommendations on how to accomplish this? I'd like to keep my current files and Channels settings through this process. Would like to avoid the expense of buying a new NAS if possible.

Also, I think I'll just go with WD Reds again (although I would've like to have gotten more than 4 years out of them), but would also be interested in recs for other brands/models to try.

Thanks!

Since you setup storage as RAID 0 (striping, no redundancy), if one drive fails, you lose everything.
I would recommend updating the DS220+ to the latest DSM version and updating any packages first.
You will have to backup everything, replace the drives and then restore the backup.
How you do that is up to you. Synology does have tools/packages for that.
If you use the same volume name and restore to the same directories, everything should work.

That's more of a question for the Synology Help/Knowledge Center/Forum.

Follow these instructions to backup and restore your Channels DVR

Synology Red NAS drives and Seagate IronWolf NAS drives are the most popular.

Simple:

In the future if you need to upgrade,

  • Pull one drive
  • add one of the the larger drives
  • let them Rebuild
  • Add the second new drive
  • let them Rebuild

During the above process, you could continue to use your NAS though access may be slower

Are you sure you can initialize a Synology DS220+ for RAID 1 if it only has one drive?
Pretty sure you need 2 drives minimum to initialize a storage pool as RAID 0 or RAID 1.
You can start with one drive if you choose SHR and later expand it.

I would check the Synology documentation for that and also what type RAID is changeable to what type RAID.

OP also stated he wants RAID 0 (striped) to maximize pool/volume size

#5

If not then enough storage for a backup is needed. I don't recommend creating another stripe. Too easy to go bad

#6

I agree. I use SHR on both of mine.

Thanks! But I'd rather not go to Raid 1, since it cuts the capacity in half. I'm looking to stick with Raid 0, but take this opportunity to update from 12TB total (6 TB/drive) to 20TB/drive.

Any thoughts on how to accomplish that, or would I need a secondary device that can Raid the two new drives together in order to properly copy form the existing drives (which are full).
