LyCOM PE102R5 interface cards/adapter

2x RAID5 SATA II, PCI-E 2Ports 3Gbps SATA II PCI Express 1X host board to support NCQ, Port Multiplier, Raid5, Raid10, Raid0, Raid1 and JBOD!
RAID 0 (Striping), RAID 1 (Mirroring), RAID 0+1 (mirrored-stripping), 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.

FEATURES
- External SATA II (eSATA) Connectors
- 48 bits LBA can Break Capacity-Limit to Support HDD larger than 137GB
- Supports 1-lane 2.5Gbps PCI Express
- Hot-plug capability
- Supports SATA II transfer rate of 3.0Gbps
- Fully compliant with Serial ATA 1.0 specifications
- Supports two independent Serial ATA channels
- Independent Link, Transport, and data FIFO
- Independent command fetch, scatter/gather, and command execution
- Supports Legacy Command Queuing (LCQ)
- Supports Native Command Queuing (NCQ)
- Supports Non-zero offsets NCQ
- Supports Out of order data delivery NCQ
- Supports FIS-based switching with Port Multipliers
- 31 Commands and Scatter/Gather Tables per Port
- Two Pin headers on board for LED connection
- RAID 5 (Distributed Parity RAID) has Highest Read data transaction rate and Good aggregate transfer rate
- Raid 5 requires Port Multiplier and 3rd Drive
- JBOD is a virtual disk that combines all disk drives as one entire disk drive
- Provides RAID 0 (Stripping) 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 0+1 (Mirrored-Stripping) 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.
