Question for people running personal NASes with RAID/similar 
How important is it to have a spare replacement disk (cold spare) ready to go at all times? My NAS runs Synology's Hybrid RAID in a 1-fail-tolerance system. All the disks are from the same batch, which I've read is kind of risky because they're likely to kind of fail together. But also I'd rather put off buying extra disks until closer to their death date when it'll be cheaper and I can potentially upgrade the whole set. Thoughts?

@s0 hmm well, running RAID1 with 2 disks here my thoughts are that if something were to happen to one of the disks, it's degraded to the same security of just having one disk in the first place, so nah, i don't keep cold spares (and there's nightly backups too)
