DescriptionThis PCI-X card provides 4 fully compliant external SATA-300 ports capable of operating at up to 3 Gbps (300 MB/s). The ports are presented externally using a Multilane 4x external connector. Supports NCQ, port multiplier, Raid 5, Raid 1+0, Raid 1, Raid 0 and JBOD. (A 4x multi-lane cable - "Inifiniband cable" - is used to connect the card to the devices).
RAID 0 (Striping), RAID 1 (Mirroring), RAID 10 (1+0 mirrored-striping), RAID 5 (Distributed Parity RAID) and JBOD (Just Bunch of Disks) manage multiple disk drives to enhance I/O performance and provide redundancy in order to withstand the failure of any individual member, without the loss of data.

Raid - JBOD - A brief explanation
RAID 5 (Distributed Parity RAID) has Highest Read data transaction rate and Good aggregate transfer rate
JBOD is a virtual disk that combines all disk drives as one entire disk drive
Provides RAID 0 (Striping) to greatly increase the performance of data transfer by simultaneously writing data to multiple drives
Provides RAID 1 (Mirroring) to protect the data from a disk failure by writing identical data on 2 drives
RAID 1+0 (Mirrored-Striping) combine both Striping and Mirroring technologies to provide both the performance enhancements that come from Striping and the data availability and integrity that comes from Mirroring
