In a RAID 6 configuration, how many drives can fail without losing data?

1 drive
2 drives
3 drives
4 drives

The correct answer is: 2 drives

In a RAID 6 configuration, data is striped across multiple drives and distributed with parity bits to protect against data loss. With a RAID 6, two drives can fail without losing any data. Option A is incorrect because a RAID 6 can only withstand 1 drive failure, not two. Option C is incorrect because three drive failures would cause data loss. Option D is also incorrect because four drive failures would result in no data being accessible.
