My understanding is that that Backblaze handles data integrity at a higher level and just treats the disks as JBOD, so I would expect the "SAN/RAID" situation across all their disks to be roughly the same. Their storage pods have always had little more than SATA controllers and port multipliers and in later iterations, direct-wired drives w/ no port multipliers.
