RAID Summary
RAID Level 0 (Disk Striping with Parity)
Use RAID 0 to combine smaller drives into one large virtual drive.
Best Read/Write performance of all the schemes listed here.
No protection from drive failure.
ADVICE: Buy very reliable hard disk drives if you plan to use this scheme.
RAID Level 1 (Mirroring)
Good read/write performance
Inefficient use of storage space (half the total space available for data)
Best protection from drive failure.
RAID Level 5
(Disk Striping with Parity)
Protection against single drive failure.
Use RAID 5 if you need to make the best use of your available storage space while gaining protection against single drive failure.
