Add SATA III ports via PCIe x1

The StarTech PEXESAT322I adds two internal and two external SATA 6.0 Gb/s ports through a single PCI Express x1 slot. It uses the ASMedia ASM1061 chipset with 48-bit LBA support and port multiplier capability. A low-profile bracket and SATA cable are included for compact builds. Drivers cover Windows XP through Windows 8 on 32-bit and 64-bit editions.

Practical limits of the PCIe x1 interface

The x1 lane caps total throughput well below the combined 6 Gb/s per port, so four drives cannot run at full speed simultaneously. SATA revision 3.0 compliance ensures backward compatibility with SATA I and II devices. Optical drives are supported alongside hard disks and SSDs. The card fits low-profile chassis without extra clearance.

Replaces add-in cards limited to SATA II

Upgrading from a 3 Gb/s controller or a single external port restores 6 Gb/s internal and external connectivity in one slot. The jump is worth it when a system lacks native SATA III ports or needs eSATA for external arrays without occupying additional expansion slots. Legacy operating systems down to Windows XP remain supported.

Questions about this item

Should I use the two internal SATA ports or the two external eSATA ports on the PEXESAT322I?

The card provides two internal SATA 6.0Gb/s connectors and two external eSATA connectors; choose internal ports for drives inside the chassis and eSATA ports for external enclosures.

What does the 6.0Gb/s transfer rate mean for my drives?

The controller complies with SATA revision 3.0 at up to 6Gb/s, so each connected drive can operate at the full SATA III link speed supported by the drive itself.

Will the PCIe x1 interface limit the 6Gb/s SATA ports?

The card uses a PCI Express x1 slot and the ASMEDIA ASM1061 chipset; the single-lane PCIe link sets the aggregate bandwidth ceiling for all four ports combined.
