Can RAID 5 survive multiple disk failures?
If a second disk in a RAID 5 disk array fails, the array also fails and its data is not accessible. If a second disk in a RAID level 5 disk array fails, you must replace the failed disks, then delete and recreate the disk array.
Can RAID 5 array be recovered if one of the disks fails?
RAID 5 protects the data with parity information distributed on all member disks. The data can be recovered from the remaining disks if one disk fails.
How many drives can I have fail at the same tie with a RAID 5 plus spare?
The system can recover from a single disk failure and during the recovery, process is vulnerable to second disk failure. Therefore, RAID 5 and RAID 5 with Hot Spare disk offer the same level of protection – single disk failure.
How many drives can you lose in raid?
A RAID set offers redundancy and can withstand the loss of up to two disks in each parity set. RAID 60 arrays are more reliable than RAID 50 arrays thanks to the extra parity disk in RAID 60. But when more than two disks in a single parity set are lost, the RAID 0 set breaks, and data recovery is needed.
