How many drives can fail in a RAID 5?
The downside to RAID 5 is that it can only withstand one disk drive failure. Thankfully, RAID 5 is hot-swappable, meaning one disk drive can be replaced while the others in the array remain fully functional.
Can you use 2 drives RAID 5?
Raid 5 requires at least 3 disks.
Which RAID configurations can tolerate 2 drive failure?
RAID 6: Because of parity, RAID 6 can withstand two disk failures at one time. This can be simultaneous failures or during a rebuild another drive can fail and the system will still be operational.
How do I replace a failed RAID 5 drive?
RAID5 is easy to work with, especially since you know exactly what disk is dead. All you need to do is power down the array, replace the dead drive, then power the array back on. The parity info spread across the drives will start re-creating the data on the new disk.
