Two internal SATA 3.0 ports

The sakose BT-PES322i adds two SATA 3.0 ports through a PCI Express 2.0 slot. It suits owners of older Windows systems such as XP, Vista or Windows 7 who need extra internal drive connections. The card supports SATA 6G, 3G and 1.5G devices and includes RAID 0 and 1 functions.

Low-profile bracket eases fit

A low-profile bracket is supplied so the card fits slim chassis without modification. Installation requires a free PCIe slot and the driver CD for the listed operating systems. Hot-swap and hot-plug work only when the connected drives and backplane also support those functions.

Sustained throughput limited by PCIe 2.0

Under continuous load the PCIe 2.0 x1 link caps total bandwidth at 5.0 Gbps, so two SATA 3.0 drives cannot both run at 6 Gbps simultaneously. Port multiplier support and NCQ help maintain steady performance across multiple drives, but the bus ceiling remains the bottleneck.

Questions about this item

How can I verify the BT-PES322i is running at SATA 3.0 speeds after installation?

Check the device manager or BIOS to confirm the SATA ports negotiate at 6Gbps, which indicates SATA 3.0 operation with connected drives.

What comes in the box with the sakose BT-PES322i and what must I provide?

The package includes the PCIe SATAIII 2-port card, a user manual and a driver CD; you must supply SATA data cables and a compatible PCI Express 2.0 slot.

Which version of the BT-PES322i should I choose for a Windows 7 64-bit system?

The card supports Windows 7 (32/64-bit) along with XP, Vista, 2003 Server and 2008 Server, so the single listed model covers that OS.
