One comment on “Dangers of RAID 5 Array with SATA Drives

  1. In our experience the most common type of RAID 5 failure is not due to the interface of the drive (ie. sata, SCSI, etc) but rather from one drive failing and the user not understanding what to do, or even worse looking online and attempting a do it yourself fix. Most RAID 5 failures that require data recovery are due to controller cards not being able to read the RAID configuration, corrupt operating systems, power failures, but mostly user error, users running RAID 5 in degrade mode without replacing the failed drive.
