Hi-Fi H170S3H / Hi-Fi B150S3H

RAID 10 combines the advantages (and

disadvantages) of RAID 0 and RAID 1 in one

single system. It provides security by mirroring

all data on a secondary set of disks (disk 3 and

4 in the drawing below) while using striping

across each set of disks to speed up data

transfers.

Features and Benets

• Drives: Minimum 4, and maximum is 6 or 8, depending on the plaorm.

• Benets: Opmizes for both fault tolerance and performance, allowing for automac

redundancy. May be simultaneously used with other RAID levels in an array, and allows

for spare disks.

• Drawbacks: Requires twice the available disk space for data redundancy, the same as

RAID level 1.

• Fault Tolerance: Yes.

A RAID 5 array can withstand a single disk

failure without losing data or access to data.

Although RAID 5 can be achieved in soware,

a hardware controller is recommended.

Oen extra cache memory is used on these

controllers to improve the write performance.

Features and Benets

• Drives: Minimum 3.

• Uses: RAID 5 is recommended for transacon processing and general purpose service.

• Benets: An ideal combinaon of good performance, good fault tolerance, and high

capacity and storage eciency.

• Drawbacks: Individual block data transfer rate same as a single disk. Write performance

can be CPU intensive.

• Fault Tolerance: Yes.
