array using RAID 1. The two mirrored arrays are then grouped as a striped
RAID 0 array using a two tier structure. Higher data transfer rates are
achieved by leveraging
TwinStor and striping (64K, 128K, 256K, 512K or 1M) the arrays. RAID 10
is available on the four, eight, and twelve port Escalade ATA RAID
Controllers

Figure 3. RAID 10 Configuration Example

RAID 5 arrays optimize performance, fault tolerance,

high capacity and storage efficiency

The RAID 5 configuration features the data striping of RAID 0 combined
with the parity of RAID 4. Using a simple parity (exclusive OR) function,
RAID 5 can tolerate the loss of one drive. Parity information is distributed
across all drives rather than being concentrated on a single disk (see Figure 4).
This avoids throughput loss due to contention for the parity drive. You can use
hot spares to rebuild a failed drive “on-the-fly”.

RAID 5 capacity = size of smallest drive

×

(number of drives - 1). In addition,

the array’s storage efficiency increases with the number of disks; from 66.7%
for 3 drives to 87.5% for 8 drives: storage efficiency = (number of drives -1)

÷

(number of drives).

Unlike all other RAID configurations that offer data striping, except for RAID
1, RAID 5 stripe size is limited to 64k.

Note:

BIOS will reject the creation of a RAID 5 array having less

than 3 drives.
