Qnap TS-412 failed drive - upgrade/replacement options?

[Northernbloke]

So I've been away for a few weeks - got an email error report from my NAS yesterday saying one of the HDD's wasn't plugged in and the raid had gone into degraded mode. It's a TS-412 with 4x 2Tb Samsung drives that have been running constantly for about 4 years now and configured as Raid 5. When I bought the bits and set it up I bought 5 drives and kept one as a spare so now I'm home I've plugged the new spare drive in and it's currently rebuilding.

My concern is that as the other 3 drives are the same age and have had the same amount of wear and tear (It runs Sickbeard and NZBGet 24/7 as well as being my main media storage for movies/music/photos/general docs etc...) so they could be due to fail any time soon and I need to figure out some options to replace/upgrade it before it becomes terminal and I lose all 5+Tb of data on there.

Any cheap(ish) NAS boxes out there anyone one would recommend - I guess increasing capacity would make sense - budget is probably max £500 including drives which I know makes things tight for getting something decent - but thats all there is

I believe I could just buy 4 new drives and replace them one at a time and let the raid rebuild each time - but that's only going to increase the stress on the remaining drives unnecessarily so should probably be a last resort.

Anyone got any recommendations please? I guess ideally I'd like to add a new NAS with bigger storage capacity, backup all the QNAP stuff onto it then in the future whack some new drives into the QNAP and keep using it.

safest bet is replace 1 drive at a time and let it rebuild

If you can push your budget a little then I can recommend Synology. Their DS415 range, paired with some WD Red's is a formidable package.

Cheers guys, good news is the new drive is in and the raid recovery completed ok and I'm off all week so can spend some time shopping around

well I broke the budget slightly lol - got a shiny new QNAP TS-453 Pro with 4 x 4Tb WD Red NASware drives to go in it (plus a spare - just in case) - I've been really happy with the old TS-412 for nearly 5 years now decided to stay with QNAP. Also figured as soon as I've backed up everything off it onto the new box I'll replace the drives in it one at a time with new ones to see if I can keep the stuff on there as well - if not then I'll just whack in the 4 new 2Tb drives I also got and start it with a clean format again

i got the 412 for my camera but im not that impressed with it,maybe the software is to bloated for it now but my 419 and 451 are ace!!!!

It's always been a little slow presumably just the single processor limits it a bit. I found sabnzbd absolutely crippled it but as soon as I switched to NZBGet performance improved a lot.
