I had a pretty catastrophic failure on both drives (WD Red) in my DS216se yesterday. Well out of warranty on both the drives and the NAS.

I came into the office to hear the NAS beeping and both drives are showing as crashed with no options to repair either them or the storage pool.

I have everything backed up and can still access the drives in Explorer as well as the DSM software but I can't appear to do anything else to fix it.

I don't stream anything locally and don't use Plex. It's just file storage for my own and my wife's businesses and somewhere to store family photos and videos taken before Google Photos.

So do I just replace the drives and move on or should I consider an upgrade to the NAS as well ? I always think I'd use the functionality a better NAS would provide (and I'd be looking at a DS220+) but I never seem to get around to it.

I wonder if replacing it all is the easiest as I can use the old as a "snapshot" whilst I can still access the NAS and the drives.

How much data are you storing?

What sort of performance do you need?

I'd say either go cloud storage, or go larger on premises and get a NAS capable of RAID6. I certainly wouldn't be replacing a 2 drive unit with another 2 drive unit -you have seen first hand what can happen.

Just 2x2TB drives with 1.4TB used, so not very much at all.

Performance just needs to ensure anything either of us work on is available from anywhere we use our laptops. We both store everything on the NAS. I think my My Documents folder has two files in it.

I prefer the idea of the storage being on the NAS rather than the cloud and having off-cloud storage is a requirement of my wife's business.

What was your setup if both drives failed together...

If you don't have a cloud backup maybe you should look at 4 drives? I've hgot a 414+ and have the cloud sync backup to Dropbox. It's pretty seamless..

You've got another backup don't you..?

Just the Synology Hybrid RAID with both drives in the same pool and as I said I have all the data backed up.

I've had the unit for about 7/8 years and the two WD Red's for nearly five years, I've barely touched it since then.

I've only ever had one hdd fail before in over 30 years of having a pc, so to have two go at the same time is interesting. But these things happen and I have everything backed up so I'm not losing any sleep over it.

Two drives from the same batch, installed at the same time, and subjected to near-identical usage patterns? Having both fail together isn't terribly surprising.

I'd buy the latest four Bay and populate two of them.

After an event where both failed at once would have me worries there is an under lying system hardware fault just waiting to go pop again..

It would be useful to know what failed here. Do either of the drives actually report a hardware (SMART) fault?

It's been trying to do a full SMART scan on one of the drives since yesterday. It just says I/O errors, the SMART extended test failed and the allocation status is crashed.

I think it's safer to just replace the unit and the drives. I can't be sure the unit is ok and I don't want to risk new drives if it isn't.

Take the drives out and put them in another system to carry out SMART checks & tests. That way you'll know for sure if they're still good for backup drives at least, or completely toast.

For both drives to crap out at the exact same time, I'd be tempted to think it may have been something power supply related.

No, drive multi drive failures in raid is pretty much a given. When one drive fails it’s always a case of oh crap get the replacement in there quick smart so raid can do the rebuild before the next drive inevitably dies.

Of course you can expect that drives from the same batch would fail around the same time as each other, but for failure to happen at the exact same time, that's where the thought that it could be power supply related, or at least something common to both drives.

Am considering replacing mine with ssds. Might have to pull the trigger now, mine are from 2014…

My 2c

I replaced an older Dlink with the cheapest Synology NAS. It's a world of difference. The Synology has so many good things about it - like good apps (cloud sync etc). So worth the upgrade.
