How important is Rotation Vibration Safeguard
Looking at getting a readynas ultra 2 for home data backups (critical data will be kept in several places, not just NAS) and media serving.
I've looked a little about what RVS is all about, but im wondering (after seeing the 'shouting at disks' video) whether RVS is important for data safety/integrity or whether it just affects performance?
I don't mind if the i lose a little write/read speed if it needs to realign or re-write data occasionally, but i am concerned about actual damage to the drives or corruption of data.
So how much of a difference does having a hard drive with RVS make, and is it worth it for a home setup, or is it only really worth the extra cash in a situation where performance/data integrity is critical like a business?

- It's good for 6-bay NAS units and rackmount units. It's vital for 12-bay rackmount units. With lots of disks there's a fair bit of vibration and without disks can drop like flies.
However on a 2-bay unit and possibly 4-bay unit probably doesn't matter too much. I don't even worry too much about it on a 6-bay unit though it is a nice feature to have.
Drives without RVS would not have been approved for your model if they weren't fine for use keeping your data intact. NetGear extensively tests drives before approving them.
Having said that if you primarily store important data on the ReadyNAS you should backup that data regularly. See Preventing Catastrophic Data Loss
There are problems like both your disks failing at once that RAID can't protect you against.
