RAID Tips 6 of 10 - Software RAID

Do not underestimate the software RAID.

  • Software RAID would typically provide the same, of not better reliability than an entry-level server hardware RAID controller.
  • Software RAID is easier to move around from server to server. It does not require an identical replacement controller in case of a controller failure, which is sometimes a hinderance with server hardware.
  • In RAID 0, RAID 1, and RAID 10, the hardware RAID controller does not provide any computational power benefit because there is nothing to offload.
  • Most modern SOHO and small business NAS devices, like Synology, QNAP, or NetGear, use the software RAID (Linux/mdadm).
