Our latest eS3_PCIe21 - A two 6.0Gb eSATA 3 PCI-Express controller in one-lane PCI Express V2.0 (.5.0Gb/sec) with two 6.0Gb eSATA 3 ports that brings the latest SATA specification, features to the desktop, support up to TEN SATA II thru Port Multiplier SPM-3726, RAID-PM, SPM393 and our Hardware raid bridge SPM394.

Our eS3_PCIe21 base on Marvell 88SE912x 3132 supports PCI Express V2.0 (5.0Gbps) and the SATAIII transfer rate of 6.0 Gbps (600 MB/s). The eS3_PCIe21 is fully compliant with the all SATA specifications including V2.6. Including Native Command Queuing (NCQ), Hot swap, hot plug, SATA port multiplier (WIndows only) with FIS-based switching, which enables the execution of commands and transfer of data to multiple drives concurrently for un-equalled data throughput over a single SATA linkof 6.0Gbpsc.

In addition, our eS3_PCIe21 fully supports ATAPI commands, making it suitable to high speed optical drives applications such as CD/DVD/BD Duplicators.

Here are the test result in our lab.

Set up Mac Pro PCI Express V1.0, test HDD Hitachi Deskstar 2.0TB 7200 rpm

Both card test under PCI Express V1.0 on MACPro OS 10.6.3 - SATA 3 would perform faster on read about 17% faster and write about 19.2%

eSATA_PCIe21 - SATA II host controller Write @ 95.8MB/sec - Read @ 111.3MB/sec

eS3_PCIe21 - SATA 3 host controller Write @ 114.2MB/sec - Read @ 130.2MB/sec
