I've got 3 Nas so I have 3 backups on 3 different locations ;-)
Plus one on having "tertiary" back ups. Back the back ups.

I've worked in IT for 25+ years now. I do not trust NAS units for data storage. I've seen data corruption far too many times when controllers act up. If you are going to use a NAS, much more important than cycling drives is to simply have a good backup of your data. External USB drives are cheap and they already can go as big as 18TB if not more. Cloud backup is also an option, but depending on how much data is involved it can take a very long time to transfer.
Agreed. Frankly, I don't trust the blackbox NAS appliances for anything. But, that's just me.I've worked in IT for 25+ years now. I do not trust NAS units for data storage.

1. Do you cycle drives in your RAID devices to try to stem the tide of unexpected failures? If so, how often? How long do you trust a modern spinny disk under moderate use?
2. Is the above disk still a good choice in 2022?
Of course, I never suggested a NAS should be used for backups. I suggested that a USB drive is used for backups of the NAS in the event that the NAS fails or corrupts data.NAS isn't for backup. It's for availability. I'd recommend anyone with a NAS have backups of anything important.
To my expensive experience Seagate HD had some heating problems in the past. Only burned one but what a shit when it happens overseas...Hey Matt,
I don't personally subscribe to replacing drives just based on age. I have several at 10+ years with 0 reallocated blocks. I do agree with initially buying drives from different vendors to try to ensure they are from separate manufacturing batches.
IMO, it would be more cost effective to either upgrade to a NAS with more hot spares installed, RAID 10, or a second NAS that could back up the entire storage requirements.
Check into options your NAS has for checking and alerting/reporting drive health. There are usually warning signs before they completely fail.
I hate Seagate because they screwed me across several server installs years ago. I'm sure they are fine now, but still can't bring myself to buy them.
I've had good luck with WD, but there is chance of lemons with any of them-- thus purchasing from different batches when installing RAID is a good idea.
+1Get SSD (which may be the only kind you can get now). No moving parts and faster transfer rates.
And don't leave them powered up 24/7. Just connect them when you need them.
That is because parity raid is dead.I have lost all faith in the RAID systems. I've had a bunch, including an 8 drive QNAP 15TB,
RAID 6 (which is now a paper weight), and every other kind, in servers and standalone.
Every one has failed at some point and the recovery success was bleak.
Swapping out bad drives is ok to a point, but they all need to be the same drive size & model,
which will eventually become unavailable.
I now use single external USB drives (latest ones I got are 5 TB). Buy a few (they're pretty cheap
these days) and make copies on all. When they fail, which they will, just replace the failed one with
whatever the latest and greatest is, and carry on. They won't all fail at the same time.

Raid 10 also has better performance.That is because parity raid is dead.
Standard practice has been raid 10 for a long time, for good reason.
Raid 1 mathematically cannot be worse than a single drive. Raid 10 still works out better in practice.
RAID 1 is fine if you don't need much storage and don't need the performance advantage of striping reads.Get a NAS that has predictive disk failure that way you dont need to replace disks that have not failed. RAID10 is supper reliable and if you can have a hot spare or two even better. If thats over kill the RAID5 or 1 or cloud, have copy of your data stored offsite... i.e recover from a fire or disaster at your business/residence.
