RAID5 rebuild time

RAID 5 array vulnerability time

If a disk fails in a RAID 5 array, the array loses its redundancy. The "vulnerability window" does thus exist until the redundancy is restored. The process of recalculating the parity to restore redundancy is known as "rebuild". What is the minimum rebuild time if

  • There were three disks and a hot spare in the array, making a total of four disks. The disks are identical.
  • The array capacity is 120GB.
  • Sustained transfer speed of the member disk is 1.5 GB/min read and 1.0 GB/min write.
  • 20 minutes

    I am not tech savy at all... which is how I somehow reformatted the disc in my digital camera on the last day of vacation, and lost all my photos and videos. I came across this download and gave it a try. [...] I did have to refer back to the demo for guidance on selecting the right "physical device". The selections it gave me were unrecognizable to me. The demo helped me understand what I was looking for. All pictures are recovered, and I am grateful! The movies were recovered as pictures (large jpeg files). I can't figure out how to convert them back to movies. Regardless, I am thrilled to have my pictures back.
