And how do you plan to detect if your data is silently corrupted? Unless you're using some archive file format that includes checksums/hashes, you have no way of knowing whether your backups are any good until it's too late.
- jasode 10y agoYour tone makes it sound like silent RAID corruption doesn't happen. That's not true, even for NAS appliances like Synology.[1] If you meant that a filesystem like ZFS with checksum blocks is designed to protect itself agains corruption errors, one can use that without RAID. A single-disk ZFS is orthogonal to RAID. To point back to the OP's question, he's running Windows with Plex. In that case, a 10TB NTFS filesystem with periodic binary comparisons/checksums (or format the disk with the newer ReFS[2] that stores checksums similar to ZFS) is simpler than RAID5/6. He also gets the extra benefit of an offsite backup without paying for cloud storage. I'm not against RAID for all cases but a home media computer with just 10TB doesn't meet the threshold of dealing with its extra complexity. However, if one is wanting to consolidate 25TB+ of disk space -- or running a business -- or need aggregated io bandwidth, the cost/benefit drivers for RAID over JBOD would make more sense.
