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

    Our customers say

    My brother has a smart media card which was taken by an old digital camera. He could not get pictures downloaded nor print them directly from the camera (he can see them on the camera screen) and photo shops in Japan had no success either. Well, I told him that I can try here in the U.S. I could see files but downloaded files looked corrupted. I took it to a professional photo shop but they could not do anything with it and, [...] A friend of mine pointed me to this site. What a heck..nothing to lose. Well, to make a long story short, the software worked beautifully and I was able to recover 167 pictures in the matter of minutes. Thanks and my brother thanks too.
