In an ideal world, you should always be in RAID mode (easy), and never buy the two (or more) HD from the same provider at the same time.

Here is a common disaster:
1) a HD starts having failure.
2) of course, you buy a new HD, and let the RAID populate the new HD (something around a few days, depends upon the size of the HD, but also upon your processor)
3) which means you put your remaining HD under huge stress, as it does a lot of read at low level continuously for a few days.
4) catastrophe: as both old HD came from same batch, the remaining old HD is also failing while transferring, meaning you loss your data

So: either buy from two different providers, like amazon or...; or alternatively, buy a new one every 2-3 years or so, and replace the oldest hD in the array; meaning you always have a new HD in the RAID array

How long does a HD last ?
A very interesting link, which gives stats on brand failure (Backblaze is a hoster - professional look at this website):
Backblaze Hard drive Stats [...]

Don't forget that the DSM won't update after a while :-)

Thanks. Interesting advice. Indeed, I chose the HGST drives because Backblaze found them most reliable, though I never thought of buying from different batches. Have you had your catastrophic scenario actually happen to you?

Yes, I'm using Synology Hybrid RAID. I've got backups on two different USB drives. I hope not to hit the jackpot on all three devices at once.

When DSM stops updating on the DS414, I'll replace the NAS. I think I'll start repopulating it now, one disk every 6 months.
