I am currently rebuilding a 28 x 1 TB RAID 5 volume that is based on the
SurfRAID TRITON 16S3 with a JBOD unit. It is 16.6% complete after 2 1/2
hours.
I am rebuilding before copying the data and returning all the Seagate 1
TB drives. Replacing it with Hitachi 2 TB drives and RAID 6.
The combination of a large number of drives in RAID 5 and/or Seagate 1
TB drives is not to be recommended.

Hello,
Has anyone here seen any numbers, or tested themselves, the rebuild
times for large raid arrays (raid 6 specifically)?
I can't seem to find anything concrete to go by, and I haven't had to
rebuild anything larger than a few TB. What happens when you loose a
2TB drive in a 20TB array for instance? Do any hardware raid solutions
help. I don't think ZFS is an option right now, so I'm looking at
Linux and/or hardware raid.
