Dat Optic's eSATA_PCIe21 2 Port eSATA PCI Express Host Adapter brings server-class features to the desktop, with support for up to ten SATA II drives via Port Multiplier technology.

Suports RAID levels 0, 1, 5, and 10
With Dat Optic's eSATA_PCIe21 base on SiI 3132 comes with drivers for the Windows, Linux and Novell Netware operating systems for both RAID and non-RAID operations. Software RAID 0 (striping), RAID 1(mirroring), RAID 1+0 (mirrored stripe), and RAID 5 (parity stripe) functions are supported through Silicon Image's SATARaid™ RAID management GUI software utility.

Designed for optimum performance
Multiple commands for each port are loaded into on-chip memory eliminating the need for host CPU intervention and minimizing PCI bus usage. Command execution engines dramatically reduce latency between commands, ensuring that drives stay fully loaded with queued commands.

PCIe Saturating Speeds
The SATA 2nd Generation standard offers speeds of up to 3Gb/s, which is plenty of bandwidth to saturate the Single Lane PCI Express connection speed of 2.5Gb/s.
