Names its power supply and its switch, which most docks never do

BENFEI dual-bay SATA dock, USB 3.0 at 5 Gbps, offline clone on a three-second press, 12 V/2.5 A supply

The dock that publishes the two things most of this shelf leaves out — a 12 V/2.5 A supply rated for two spinning drives, and a power switch to protect them while they are fitted.

On the listing

A USB-C dual-bay drive docking station with offline cloning for 2.5-inch and 3.5-inch SATA HDDs and SSDs, USB 3.0, 5 Gbps, UASP, tool-free; parallel reading, writing and transfer between two drives, offered for backups, migrating a system to a new drive and expanding storage; offline cloning at the press of the CLONE button held for three seconds, transferring all data from the source to the destination without a computer, with a note that the destination must be equal to or larger than the source; USB 3.1 Gen 1 transfer at up to 5 Gbit/s with UASP claimed to speed transfers by up to 20 % against conventional USB 3.0; a dedicated 12 V/2.5 A power supply giving a stable supply to both bays even with two demanding 3.5-inch hard discs, with an integrated power switch protecting the drives during connection and removal and an instruction to switch off first; and an 18-month warranty.

Twelve volts, two and a half amps

Five of the seven docks in this hub never mention how they are powered. This one gives both numbers and says what they are for.

Two 3.5-inch mechanisms spinning up simultaneously is the peak load a dock ever sees, and it is where an inadequate adapter fails — not with a bang, but with a drive that disappears mid-copy or a device that works with one disc and not two.

The fourth bullet gives 12 V and 2.5 A and names that exact case: reliable operation even with two demanding 3.5-inch hard discs. It is the higher of the two current ratings published on this shelf.

That is a claim a buyer can check rather than trust, which is the whole difference between a specification and an adjective.

The switch, and the instruction with it

The same bullet describes an integrated power switch and then tells you when to use it: switch the unit off before connecting or removing drives.

A SATA connector mated under power is the moment things go wrong, and every dock user has done it because there was no switch and no reason given. Publishing the instruction alongside the hardware that makes it possible is the useful version of a safety note.

Three seconds, and the capacity rule

The second bullet covers the clone in one line: hold CLONE for three seconds, and the destination must be equal to or larger than the source.

Both halves are worth having and one of them has a sting. Equal or larger is the condition; what follows from it, and what the bullet does not say, is that everything already on the destination is overwritten.

This site describes the function as duplication rather than as a way of keeping data safe. The first bullet uses the word backup for it; a clone is a copy of one moment on the same desk, and it survives none of the events a backup arrangement exists for.

Two names for one interface

The title says USB 3.0. The third bullet says USB 3.1 Gen 1.

Both are printed and both describe a five-gigabit link — they are two naming conventions for the same class, adopted at different times. Nothing on the page reconciles them, so both are reported here rather than one being tidied away.

Twenty per cent, and seventy

The third bullet puts the UASP gain at up to 20 % against conventional USB 3.0.

The same maker’s 2.5-inch enclosure, on the enclosures shelf of this site, puts it at 70 %.

Both figures are the maker’s own and both appear where they appear. The gap is a reminder of what such a percentage is: the result of one measurement in one set of conditions, not a property of the protocol. UASP is worth having either way, and the number attached to it should be read as a claim rather than a constant.

Before ordering

Note that no capacity ceiling is published anywhere on this page, unlike four of the other docks here, so a very large drive is a question for the seller. Ask what cable is in the box. And use the switch: the listing tells you to, and it is the reason it is there.

    FIDECO dual-bay SATA dock, USB 3.0 at 5 Gbps, offline clone on a five-second press, 2 × 12 TB

    The cheapest dock in this hub, and the one that tells you exactly how the copy is started: hold Clone for five seconds until the light blinks, with no computer attached.

    Bay count
    Two — stated in the third and fourth bullets, which describe two drives put into their respective slots and two drives supported at the same time
    Supported drive sizes
    2.5-inch and 3.5-inch — stated in the title and in the fourth and fifth bullets, which describe the flexibility of connecting two drives of either size to a computer
    Supported drive interfaces
    SATA I, II and III, hard discs and solid-state drives — stated in the fourth bullet, with the first adding that only SATA drives and SSDs are supported
    Solid-state slot support
    Not published on the listing — no M.2 position of any kind is named. Solid-state drives are supported in the two SATA bays and no separate slot exists
    Offline cloning
    Stated — the third bullet says two drives are put in their slots and the Clone button held for five seconds until the LED blinks, and that the copy is completed without a computer. It is the only listing on this shelf to publish both the duration of the press and the signal that confirms it
    Interface standard
    USB 3.0 — stated in the title and in the second bullet
    Stated link rate
    Up to 5 Gbps — stated in the second bullet as a very fast data transfer speed over USB 3.0
    Connector type
    Not published on the listing — no socket and no cable is named in any bullet
    UASP support
    Not published on the listing — UASP is not named anywhere. Fourteen of the nineteen listings in this lot publish it, so the silence here is worth noticing rather than assuming
    Power supply
    Not published on the listing — no adapter, no voltage and no current is named, on a dock that accepts two 3.5-inch drives at once and cannot run from a USB port
    Per-bay controls
    Not published on the listing — no power switch and no per-bay light is named. The third bullet describes a single LED that blinks when the clone starts

  • GRAUGEAR M.2 docking station with a top slot and a cooling fan

    GRAUGEAR single-slot M.2 dock for NVMe and SATA, RTL9210B, 2230 to 22110, active fan

    The one dock in this hub with no SATA bay at all: a single M.2 slot with active cooling, the only listing anywhere in this lot to accept a 22110 module.

    Bay count
    One — a single M.2 slot. No 2.5-inch or 3.5-inch bay exists, which makes it the only dock on this shelf that will not take a conventional drive at all
    Supported drive sizes
    M.2 modules only — the third bullet names all common M.2 formats from 2230 to 2280 and adds 22110, which no other listing in this lot mentions
    Supported drive interfaces
    NVMe M.2 SSDs in M-key and SATA NGFF SSDs in M+B key — stated in the second bullet, which credits the RTL9210B chipset with the dual support
    Solid-state slot support
    The whole device is one — the M.2 slot is the only position, and it accepts both the NVMe and the SATA protocol. Every other dock on this shelf has SATA bays and, in one case, an M.2 slot alongside them
    Offline cloning
    Not published on the listing — no clone button and no copy function is named in any of the five bullets. With a single slot there is no second drive to copy to
    Interface standard
    USB with the RTL9210B chipset — stated in the second bullet. The USB generation is not named in words; the first bullet gives the rate instead
    Stated link rate
    Up to 10 Gbit/s for a PCIe 3.0 x2 NVMe SSD, and up to 6 Gbit/s for a SATA SSD — both stated in the first bullet, which is the only listing in this lot to publish a separate figure for each protocol
    Connector type
    Not published on the listing — no Type-C, Type-A or cable is named in any bullet
    UASP support
    Not published on the listing — UASP is not named anywhere. Fourteen of the nineteen listings in this lot publish it
    Power supply
    Not published on the listing — no adapter, voltage or current is named. An M.2 module and a small fan are a modest load, and the page does not say whether the dock runs from the lead
    Per-bay controls
    Not published on the listing — no switch and no indicator is named. The third bullet supplies an acrylic cylinder for storing and protecting an M.2 drive, which is a case rather than a control

    4260746550467
    • A fan inside, which nothing else in this lot has
    • Accepts 22110 modules, the only listing here to name that length
    • No SATA bay at all, so a 2.5-inch or 3.5-inch drive will not go near it

    Best for: A desk where M.2 modules are read and imaged one after another and the drive has to stay cool while it happens.

    The dock with the biggest bays and the biggest supply on this shelf — two 20 TB drives and a 12 V/3 A adapter — and lights that say which of those two states the drives are in.

    Bay count
    Two — stated in the title as a dual bay docking station taking 2 × 20 TB drives
    Supported drive sizes
    2.5-inch and 3.5-inch — stated in the title and in the fourth bullet, which says the product is compatible with almost all types of 2.5-inch and 3.5-inch HDDs and SSDs on the market
    Supported drive interfaces
    SATA hard discs and solid-state drives — stated in the title. No SATA revision is named
    Solid-state slot support
    Not published on the listing — no M.2 position is named. Solid-state drives are supported in the two SATA bays and no separate slot exists
    Offline cloning
    Stated — the second bullet says the docking station is equipped with offline cloning and that a computer connection is not required. No press duration, no capacity rule and no failure signal is published
    Interface standard
    USB 3.0 — stated in the title and in the third bullet, which adds UASP support and hot-swapping
    Stated link rate
    Not published on the listing — no figure in gigabits per second appears in any bullet. The third bullet says the dock supports not only USB 3.0 but also UASP, which it credits with even faster transfer speeds, and gives no number. It is the only dock on this shelf that publishes no rate at all
    Connector type
    A USB 3.0 Type-C data cable is listed in the fifth bullet as part of the package. The socket on the dock itself is not described
    UASP support
    Stated — the third bullet names UASP alongside USB 3.0 and hot-swapping. No percentage and no condition is published
    Power supply
    A 12 V/3 A adapter — listed in the fifth bullet as part of the package. It is the highest current rating published on this shelf
    Per-bay controls
    Not published on the listing as per-bay — the first bullet describes RGB LEDs that blink quickly when a drive is working and change to a breathing pattern when the drives are idle or removed. No switch and no individual bay control is named

    Connector type
    Type-C — stated in the second and third bullets, which name a USB-C cable and say a Thunderbolt 3 computer is compatible with it
    Power source
    From the lead — no mains adapter is named, which is the ordinary arrangement for a 2.5-inch enclosure. The fourth bullet calls it a way of adding storage without opening a laptop
    Case material

    The 3.5-inch enclosure that says in capitals that no drive is included, then lists everything that is: a 12 V/2 A adapter, a USB 3.0 lead, a manual and a service card, for drives up to 20 TB.

    Supported drive size
    3.5-inch and 2.5-inch SATA I, II and III drives up to 20 TB — stated in the first bullet, which opens in capitals to say that this is an enclosure only and contains no drive or SSD, and that a 3.5-inch SATA drive must be bought separately
    Supported drive height
