Keep a working direct SSD connection, or compare Anker 332 and 555 when a hub solves a real port shortage. Check data rate, the data socket, accessory power and safe removal separately.

A8383 lists 10 Gbps data ports. Compare it when extra ports solve a real problem, after verifying drive power, host and cable requirements.
Skip it if: The direct connection already works, or the exact SSD/power arrangement remains unresolved. It is not a verified SSD compatibility claim.
View this model on Amazon Check manufacturer details ↗A8355 is the basic-hub route when its listed data limit and complete feature/power checks meet your task.
Skip it if: You require a 10 Gbps data path, an unsupported accessory power arrangement or features outside its specifications.
View this model on Amazon Check manufacturer details ↗A portable SSD does not need a hub just because your desk has one. Keep a supported direct laptop connection when it leaves enough ports for your other equipment. Consider a hub when it removes a recurring port shortage or simplifies a setup you actually use.
For a documented 10 Gbps USB data requirement, Anker 555 A8383 is the relevant candidate in our two-hub comparison; Anker 332 A8355 lists 5 Gbps. Neither label verifies a particular SSD’s power needs or promises a file-copy speed. Resolve those checks before ordering.

Check its USB data capability, not just the shape of the socket.
A8355 lists 5 Gbps; A8383 lists 10 Gbps. PD-IN is a separate charger input.
Verify the drive’s interface, cable and accessory-power needs.
Write down the laptop port, drive cable and intended hub data port. USB-IF treats data capability separately from connector shape. A USB-C plug fitting the socket does not establish the data rate of the complete connection.
Samsung’s T7 Shield manual is a useful example: it specifies a 10 Gbps interface for optimal performance, says lower interfaces can reduce performance, and includes both USB-C-to-C and USB-C-to-A data cables. It also identifies host UASP support as a performance factor. This illustrates why the drive’s own instructions matter; it is not a tested T7 Shield/Anker pairing.
| Your situation | Starting route | Main check |
|---|---|---|
| A direct connection works and leaves enough ports | Keep the drive and its supported cable | No hub purchase is needed |
| You need extra ports; a listed 5 Gbps ceiling is enough | Compare A8355 only after checking the rest of the plan | It does not provide a 10 Gbps data path |
| Your required data path is listed at 10 Gbps | Compare A8383, or keep a suitable direct port | Host, cable, drive and accessory power remain separate checks |
| Disconnects or a missing power specification are unresolved | Investigate the exact drive and connection first | A higher rate or laptop-charging headline is not a diagnosis |
A8355 and A8383 have different jobs assigned to their sockets. The USB-C PD input is for a suitable charging supply; it is not the SSD data connection. Use a documented USB data port and the drive’s supported data cable.
A8383 lists 10 Gbps USB-C data and USB-A data connections. A8355 lists 5 Gbps data connections. Their laptop pass-through charging specification describes the laptop-power route, not an accessory-power allowance for your drive. Do not infer that a 100 W input can supply a 100 W USB accessory.
A8355’s published accessory figures distinguish its two USB-A ports, which share a total 4.5 W, from its USB-C data output, listed at 7.5 W. Compare the exact drive’s requirements and everything else using the relevant ports; a per-route figure is not permission to add every port’s headline together.
A8383’s page says its data ports are not for charging use, without establishing a universal SSD power guarantee. That wording should not be turned into either “all bus-powered drives work” or “data ports supply no operating power.” If the drive and hub documents do not establish the arrangement, keep a supported direct route or obtain model-specific clarification before buying.
If you already have the drive and hub, compare a nonessential sample copy over the existing supported direct route and intended hub route. Keep the same source files and destination, and note the cable, selected socket and other active peripherals. A different file mix or source disk can change a copy result.
This is a suggested owner check, not a benchmark we performed. Do not publish a measured result unless you actually recorded it. If the hub arrangement has an unresolved reliability problem, do not buy a faster cable or replacement SSD simply because the rate labels look different.
Reserve space for the drive and cable exits rather than leaving the SSD hanging from a short lead. Check the drive’s supplied cable before adding a replacement to the basket. Keep any laptop charger needed by the chosen arrangement; an accessory data connection and laptop charging are separate jobs.
Before disconnecting the drive, use the operating system’s safe-removal process. Samsung explicitly requires eject/unmount/safely remove for T7 Shield. If a USB sharing switch moves the drive between computers, switching also disconnects it from the previous host; do not switch during a transfer.
Use the hub checklist to compare the data requirement alongside displays, cards, network and laptop charging. A feature match is a shortlist, not a drive-compatibility test. Keep working equipment, buy a hub only for a defined missing connection, and leave the drive model unchanged unless a separate storage need justifies replacing it.
