SMUGDESK Dual eSATA + USB Power to Dual SATA Adapter Card 2.5

SKU CH-40K5-33PY2

Converts two internal SATA ports to dual power-enabled eSATA for 2.5" drives

  • Converts internal SATA to external power-over-eSATA for 2.5 drives
  • Delivers data and power through a single eSATA connection
  • Supports two independent SATA channels for simultaneous drive operation
  • Compact PCB design mounts inside the chassis for external access
  • Plug-and-play with Windows and Linux without extra drivers

Dual eSATA Adapter for 2.5" Drives

This adapter card converts two internal SATA ports into two external power-over-eSATA ports. It enables direct connection of 2.5" SATA hard drives and SSDs without separate power adapters. The design supports external storage backup and desktop disk expansion.

Power Integration via USB

The card combines eSATA data transmission with USB power delivery on each port. This arrangement removes the need for external power bricks when operating 2.5" drives. Two independent SATA channels provide stable high-speed data transfer for each connected device.

Verify Internal SATA Ports

Check that your motherboard or controller has two free internal SATA ports for the adapter headers. Ensure a spare internal USB header or port is available to supply power to the eSATA connectors. Confirm your chassis has a suitable bracket opening for the external ports.

Questions about this item

Will the USB power supply need upgrading if I connect two 2.5" SSDs?

The card draws USB power for both eSATA ports, so a standard motherboard header or rear USB port typically supplies enough current for two 2.5" drives.

Which interface caps throughput first during long transfers?

The SATA III channels set the ceiling; each port tops out at the SATA III line rate, so sustained reads and writes cannot exceed that limit.

Does the adapter generate noticeable heat when running all day?

The compact PCB has no active cooling, but power draw is limited to two 2.5" drives over USB power, so temperatures stay low inside a ventilated chassis.
