Five Internal SATA III Ports

The Vantec UGT-ST655 adds five internal SATA III 6Gbps ports through a single PCIe x4 slot. It connects SSDs, HDDs and optical drives simultaneously. No drivers are required for Windows 11, 10, 8 or 7, and Linux is also supported. Standard and low-profile brackets are included in the box.

Suits Builders Needing Extra Drive Bays

This card suits desktop builders who have run out of motherboard SATA headers and own a free PCIe x4 slot. It does not suit systems that lack a PCIe x4 lane, nor buyers who need external eSATA connectors. SATA cables are not included, so purchasers must supply their own.

PCIe v3.0 x4 Interface Requirement

The card requires a PCIe v3.0 x4 slot to deliver full 6Gbps bandwidth across all five ports. Installing it in a smaller lane width will reduce available throughput for simultaneous drive access. Verify that your motherboard provides an x4 electrical connection before purchase.

Questions about this item

What comes in the box and do I need to buy SATA cables separately?

The box includes the 5-Port SATA III 6Gbps PCIe x4 Host Card, a Quick Installation Guide, and both standard and low-profile brackets. SATA cables are not included and must be purchased separately.

Should I choose the standard or low-profile bracket for my case?

Both brackets are supplied, so you can fit the card in a full-height chassis using the standard bracket or a slim 22 mm low-profile chassis using the included low-profile bracket.

What does the 6 Gbps SATA III rating mean when all five ports are used at once?

Each of the five ports supports SATA III 6 Gbps, and the PCIe 3.0 x4 host link provides enough bandwidth for all ports to read and write simultaneously at that speed.
