On the listing

An RGB USB 3.0 and USB-C port drive docking station with offline cloning for 2.5-inch and 3.5-inch SATA HDDs and SSDs, dual bay, taking 2 × 20 TB, with UASP support; RGB LEDs that blink quickly when a drive in the dock is working and change to a breathing pattern when the drives are idle or removed; offline cloning with no computer connection required; support for USB 3.0 and UASP for faster transfers, with hot-swapping supported; compatibility with almost all types of 2.5-inch and 3.5-inch HDDs and SSDs on the market; and a package containing the docking station, a user manual, a 12 V/3 A power adapter and a USB 3.0 Type-C data cable.

Twenty terabytes a bay, and three amps to run them

The two largest numbers on this shelf are on the same page, and they belong together.

The title claims 2 × 20 TB. The fifth bullet lists a 12 V/3 A adapter.

That pairing is the reason to take the capacity claim seriously. Two 20 TB mechanisms are the biggest, hungriest drives sold, and the moment they both spin up is the peak load a dock ever sees. An adapter chosen to just about cope is how a dock ends up dropping a drive halfway through a copy.

Two of the seven docks in this hub publish an adapter rating. This is the higher of the two, and it is on the dock making the largest capacity claim. The specification is at least internally consistent, which is more than can be said for the four pages here that state a capacity and never mention power at all.

The lights, explained

The first bullet describes two states: LEDs blinking quickly while a drive is working, and a breathing pattern when the drives are idle or have been removed.

That is a small piece of documentation doing real work. The commonest question with a dock is whether it has finished, and the commonest way of answering it is to stare at a light and guess. Two named patterns settle it from across the room.

What is not described is a failure state — one dock on this shelf publishes what a failed copy looks like — and no switch is named for turning the lighting off, which one other dock here offers.

The clone, in one sentence

The second bullet says the dock is equipped with offline cloning and that a computer connection is not required.

That is the whole of it. No press duration. No capacity rule. No note about what happens to the destination.

The other cloning docks in this hub do better: three of them state the capacity condition and two describe the button press. Here the function is named and the operation is left to the manual.

This site describes the function as duplication rather than as a way of keeping files safe. A clone is a copy of one moment on the same desk, and the rules that govern it — destination at least as large, everything on it overwritten — come from the maker’s own instructions, which on this page are not on the page.

No link rate.

Every other dock on this shelf publishes a figure, and every one of them says 5 Gbps or 10. This listing says USB 3.0 and UASP and calls the result faster, without a single number in gigabits per second.

USB 3.0 implies a five-gigabit class link, which is what the rest of the shelf publishes for the same designation. But implication is not publication, and this is the one page here that leaves it to be inferred.

Before ordering

Read the manual before the first clone, because the page does not carry the rules. Note there is no switch for the lighting if the dock is going in a bedroom. And take the supply rating as the reason to prefer this over the cheaper docks if two large mechanisms are going to run at once.

More drive docks

  • SABRENT flat docking station with an M.2 slot and a SATA drive bay

    SABRENT flat dock for M.2 NVMe and 2.5/3.5-inch SATA, USB-C at 10 Gbps, offline clone, M.2 heatsink

    The only dock in this hub that reads an M.2 module and a conventional SATA drive at the same time, which is exactly the pair of things a machine being retired usually contains.

    Bay count
    Two positions of different kinds — one M.2 slot and one SATA bay, described in the first bullet as supporting M.2 PCIe NVMe SSDs and 2.5-inch or 3.5-inch SATA SSDs and HDDs at the same time. The third bullet says it can be run in single-drive or dual-drive mode
    Supported drive sizes
    2.5-inch and 3.5-inch SATA drives, and M.2 modules — stated in the title and in the first bullet. The individual M.2 lengths are not published on the listing
    Supported drive interfaces
    M.2 PCIe NVMe, and SATA SSDs and hard discs — stated in the title and in the first bullet. Whether the M.2 position also accepts M.2 SATA modules is not published
    Solid-state slot support
    An M.2 slot with a heatsink and an integrated thermal pad — stated in the title and in the fourth bullet, which gives keeping the hardware cool and protected as the reason. It is one of two docks on this shelf with an M.2 position and the only one that pairs it with a SATA bay
    Offline cloning
    Stated — the first and third bullets both describe cloning offline between two drives, with the third adding that the dock can be operated in single-drive or dual-drive mode for transfers. No press duration and no capacity rule is published
    Interface standard
    USB 3.2 Gen 2 — stated in the second bullet, which adds that the dock is backward compatible
    Stated link rate
    Up to 10 Gbps with a suitable USB host port — stated in the second bullet. The host-port clause is the only condition of its kind published on this shelf, and it is one of three in the whole lot
    Connector type
    Type-C — stated in the title and in the first bullet, which calls it a USB Type-C flat docking station. No cable is named
    UASP support
    Stated — the second bullet names both TRIM and UASP, giving reliability and performance as the reasons
    Power supply
    Not published on the listing — no adapter, voltage or current is named, on a dock that accepts a 3.5-inch drive and therefore cannot run from a USB port alone
    Per-bay controls
    Not published on the listing as per-bay — the fourth bullet names LED indicators keeping the user informed during all operations, and no switch and no individual position control is described

    Stated link rate
    Up to 6 Gbps — stated in the title and in the first bullet against the USB C 3.2 Gen 2 port. Six gigabits per second is the rate of the SATA III standard the drive speaks rather than of a USB 3.2 Gen 2 port, and the listing prints the two against each other
    Connector type
    Type-C — stated in the title and in the first bullet, with the fourth adding that the 50 cm USB-C cable is detachable so that it can be tidied on a desk
    Power source
    From the lead — no mains adapter is named. The second bullet describes the drive being powered down after three minutes of inactivity, which is a power behaviour rather than a supply
    Case material
    ABS plastic with an internal EVA foam pad — stated in the third bullet, which credits the ABS with good heat dissipation and shock resistance and the foam with holding the drive and protecting it from scratches during installation
    Cooling
    Passive — the third bullet credits the ABS housing with good heat dissipation and names no fan and no vent. It adds a built-in protection system against overcurrent, overvoltage and overheating
    UASP support
    Stated — the first bullet names the UASP protocol and says it offers up to 70 % more speed than ordinary USB 3.0 when paired with a UASP-capable host controller. The second adds TRIM and S.M.A.R.T. support
    Tool-free access
    Tool-free — the fourth bullet says the tool-free construction makes fitting or changing the drive quicker and more convenient

    Bay count
    One — a single 2.5-inch drive, held by the internal EVA foam described in the fifth bullet
    Interface standard
    USB C 3.2 Gen 2, with a Type-A plug as well — stated in the title. The second bullet adds backward compatibility with USB 2.0 and 1.1
    Stated link rate
    Up to 10 Gbps — stated in the title and in the second bullet as the maximum data transfer rate, alongside UASP SATA III support. It is the joint highest figure on this shelf
    Connector type
    Type-C and Type-A — stated in the title and in the third bullet, which describes connection to laptops, desktops and all-in-one computers
    Power source
    From the lead — no mains adapter is named anywhere on the page, which is the ordinary arrangement for a 2.5-inch enclosure
    Case material
    ABS plastic with an internal EVA foam pad — stated in the fifth bullet, which credits the ABS with excellent heat dissipation and shock resistance and the foam with holding the drive and preventing scratches during installation
    Cooling
    Passive — the fifth bullet credits the ABS housing with heat dissipation and names no fan and no vent, adding a built-in multiple protection system against overcurrent, overvoltage and overheating
    UASP support
    Stated — the second bullet names compatibility with the UASP SATA III transfer protocol and claims it is 70 % faster than conventional USB 3.0. No condition on the host controller is published
