CHAPTER 4: USING YOUR DESKTOP

RAID Level 0

CAUTION: RAID level 0 provides no redundancy. erefore, a failure

of one drive results in the loss of all data. Perform regular backups to

protect your data.

RAID level 0 uses data striping to provide a high data access rate. Data striping

writes consecutive segments, or stripes, of data sequentially across the physical

drive(s) to create a large virtual drive. is allows one of the drives to read data

while the other drive is searching for and reading the next block.

RAID 0 uses the full storage capacities of both drives. For example, two 2 GB hard

drives combine to provide 4 GB of hard drive space on which to store data.

NOTE: In a RAID 0 conguration, the size of the conguration is equal to

the size of the smallest drive multiplied by the number of drives in the

conguration.

RAID Level 1

RAID level 1 uses data mirroring to enhance data integrity. When data is written

to the primary drive, the data is also duplicated, or mirrored, on the secondary

drive in the conguration. RAID 1 sacrices high data-access rates for data

redundancy.

If a drive failure occurs, read and write operations are directed to the remaining

drive. A replacement drive can then be rebuilt using the data from the remaining

drive.

NOTE: In a RAID 1 conguration, the size of the conguration is equal to

the size of the smallest drive in the conguration.
