How long does a RAID 1 rebuild take?

Splendid. It takes about 1.5 hours to rebuild my RAID1, comprised of 2 WD 500GB, 2/3 full, using Intel Matrix Storage Manager.

How do I calculate RAID rebuild time?

You can calculate the best-case rebuild rate fairly simply: as rebuild is sequential, the needed time is capacity / transfer rate . For example, rebuilding a 10 TB disk with a 200 MB/s transfer rate needs at least 10000000 / 200 = 50000s = ~14h .

Can you recover RAID 1?

The RAID Recovery by DiskInternals works with all RAID types by connecting the array elements as couple of single disks. The recovery process is performed without the controller or array transferring. If you need it, the disk image can be recovered to be saved elsewhere.

How many drives can fail in a RAID 1?

Hot spares act as standby drives in RAID 1, RAID 5, or RAID 6 volume groups. They are fully functional drives that contain no data. A hot spare drive is not dedicated to a specific volume group. Instead, you can use a hot spare drive for any failed drive in the storage array with the same capacity or smaller capacity.
