Super important if you invest in a raid: get a battery backup for power. I had a drobo go down on my from a brownout and lost some photos. Now i have battery ba

  I've been using Synology NAS devices for some time now and I'd definitely recommend them too. They have great support, even for their 'budget' systems, and provide many years of software updates and fixes. Their main web interface doesn't suck, and they also support SSH and command line management of the devices too. I've not invested in backup power, but this is one area that I'm a little skeptical of... nowadays all filesystems are supposedly advanced (log-structured records, etc) so in the event of power loss, in 'theory' you should only be losing at most a few minutes of work, depending upon caching. i.e. stuff that hasn't yet been written to disk might be toast, but everything else should be safe. Or can worse corruption still happen? (quick edit to add: I'm not saying that backups are a waste of time, not at all, just that I'm questioning having a short battery power-supply backup)

    Corruption can always occur if the moons and sun don't align for you on the day of the power outage. Battery backup is usually req'd if you want to use write-caching on your RAID. You can also use flash backed RAID controllers, it's prolly better than a battery backup today. Ultimately, keep things in perspective. The battery backup option might be the same cost as a decent UPS. You can also always build your own or get a decent zfs appliance.
