Any recommendations for a NAS that will likely only be used for a backup? I've worked with a Synology and I'm a fan of it, but I'm fairly limited in how frequently I've worked with NAS'.
Along those lines, what type of Raid do people recommend. I'll be using Raid 10 on my servers, and I'm sure Raid 10 would be great on the NAS, but my concern there is the amount of storage you lose. Is a Raid 5 sufficient for backup purposes?
