Two-Port SATA2 ExpressCard Adapter

The CoolGear SS-2EXP is a 34 mm ExpressCard/34 adapter that adds two external SATA ports to a notebook. It uses a Silicon Image SiI3132 controller compliant with ExpressCard 1.0 and supports both 1.5 Gb/s and 3.0 Gb/s SATA2 devices. An onboard ROM BIOS enables booting from attached drives larger than 137 GB. The card also works with SATA2 port multipliers for expanded connectivity.

Suitable for ExpressCard Notebook Users

This card suits owners of laptops equipped with an ExpressCard/34 or ExpressCard/54 slot who need to connect external SATA hard drives or SSDs. It is not for systems that lack an ExpressCard interface, nor for users who require internal SATA connectors or transfer rates beyond the 3.0 Gb/s SATA2 limit.

SiI3132 Dual-Channel SATA2 Controller

The onboard SiI3132 chip provides two independent SATA2 channels, each capable of 3.0 Gb/s throughput. Legacy Command Queuing support helps maintain performance with multiple attached devices. This controller choice determines compatibility with SATA2 drives, port multipliers, and boot-capable BIOS implementations.

Questions about this item

Does the CoolGear SS-2EXP ship with any cables or do I need to buy eSATA cables separately?

The product data lists only the card with two external SATA ports; no cables are mentioned, so eSATA cables must be purchased separately.

The card is labelled ExpressCard/34mm but the specs also mention ExpressCard/54 — which one should I choose for my laptop?

The SS-2EXP is a 34 mm card; it fits both 34 mm and 54 mm slots, so choose this model if your laptop has either ExpressCard form factor.

What real-world throughput can I expect from the 3.0 Gb/s SATA2 ports once the card is installed?

Each port runs at up to 3.0 Gb/s (SATA2 speed); actual transfer rates depend on the attached drive and system overhead but will not exceed the 3.0 Gb/s link limit.
