I believe every file system was designed not to fail.

As a digital photographer with terabytes of RAW and JPG2000 photos archived over the years, I began to realize that NTFS isn't as bitperfect as I used to believe. A common phenomenon with JPG2000 and some lossless image compression file formats was distorted stripes in stored images over the years. I wouldn't believe it unless I experienced it myself. It seems like some additional ecc layers are needed for long term storage and from my reading it appears the self healing function of REFS is approaching this. I am on RAID5 after losing a lot of good work but it has it's own inherent vulnerabilities (write hole) which from my reading it appears storage spaces entirely circumvents.

This is very informative thank you for the overview, there is surprisingly little good information on REFS on the web. Will the self healing feature of REFS function when it is used on a removable device? Is there any benefit to running REFS on a raid5 array, or would that be entirely redundant? It seems that the storage spaces parity is in some ways superior to RAID in fault tolerance minus the performance. Thanks
