What are two types of RAID
Hardware and Software RAID
RAID ____ is not fault tolerant. Main benefit is speed
RAID 0
Most popular RAID level
RAID 5
What RAID level carries out mirroring or duplexing were the data on the disk is copied onto one disk or a pair of disks
RAID 1
Which RAID level writes two parity blocks to help data recovery process
RAID 6
Combines fault tolerance with increased performance/speed by relying on striping with distributed parity
RAID 1+0/10
