Q: What does this product do? How does it work?
A: This expansion dock connects to your computer via a single USB4 40Gbps port and expands it into two independent PCIe x4 slots. Two PCIe-to-4-port SATA expansion cards are pre-installed inside, converting the dock into an 8-port SATA 6Gbps storage expansion solution. You can connect up to 8 SATA SSDs or HDDs for use as a high-speed external storage array, media library, video editing cache pool, or data backup system.
Q: What is the upstream interface? Which host devices are compatible?
A: The upstream interface is USB4 40Gbps, compatible with Thunderbolt 3, Thunderbolt 4, and Thunderbolt 5. It works with Windows 10/11, macOS, and Linux systems that have a USB4 or Thunderbolt port. A 40Gbps USB4 cable is included in the package.
Q: What SATA speeds are supported?
A: The SATA ports comply with the Serial ATA 3.1 specification and support communication rates of 6.0 Gbps, 3.0 Gbps, and 1.5 Gbps, automatically negotiating with the connected drive.
Q: Does it support hot-swap?
A: Yes. The dock supports both hot-plug and hot-swap, allowing you to swap drives without restarting your system.
Q: How are the 8 SATA ports connected? What cables are included?
A: The dock uses SFF-8088 multi-lane connectors internally. One SFF-8088 to 4×SATA breakout cable is included in the package, providing 4 SATA connections. To use all 8 ports, a second SFF-8088 to 4×SATA cable (not included) is required and must be purchased separately.
Q: Does it support NCQ (Native Command Queuing)?
A: Yes. NCQ is supported, which improves drive performance by optimizing the order in which read/write commands are executed.
