UGREEN grey 2-in-1 card reader with a USB Type-A plug, a Type-C plug and SD and microSD slots

UGREEN 2-in-1 reader, USB-A and USB-C, SD 3.0, two slots read at once, 5 Gbps and 170 MB/s stated

The reader on this shelf that qualifies its own headline number in the same breath as printing it: 170 MB/s, and a note saying you get it only if the card can do it too.

Host interface standard
Not published as a USB generation — no 3.0, 3.1 or 3.2 designation appears in the title or the bullets. What the title does name is SD 3.0, which is the card-side standard rather than the host one, and the second bullet gives the host link as a rate instead: up to 5 Gbps
Stated link rate
Up to 5 Gbps — stated in the second bullet, with up to 170 MB/s named for use with a UHS-I card. The same bullet carries the maker’s own note in brackets: the 170 MB/s figure holds only where the SD or microSD card supports that speed as well. It is one of two listings on this shelf to attach a written condition to its own figure
Connector type
Type-A and Type-C on one body — stated in the title and in the first bullet, which describes connecting a memory card to a computer or a phone through either interface
Internal or external form
External — a compact body that plugs straight into a socket. The fourth bullet describes it as a direct plug-in adapter with no lead, and the fifth names low weight and portability as the point
Slot count
Two — stated in the first bullet, one for full-size SD and one for microSD
Formats accepted
SD, SDHC, SDXC, microSD, microSDHC and microSDXC — stated in the first bullet, with cards of up to 2 TB named. No CF, MS or XD support is claimed anywhere
Simultaneous slot access
Both slots at once — stated in the first bullet, which says the two slots allow two cards to be read at the same time. It is written as a capability rather than left to be discovered
Stated protocol support
UHS-I — named in the second bullet as the card mode the 170 MB/s figure applies to. No UHS-II mode is claimed, and the title names SD 3.0 as the card standard
Cable arrangement
No cable — the reader plugs directly into the socket, stated in the fourth bullet as doing away with tangled leads and bulky multi-function adapters. The third bullet adds a practical caveat: a case on a phone can stop the Type-C plug seating properly, and the maker recommends removing it

On the listing

A 2-in-1 card reader with a USB-A and a USB-C interface, joining a memory card to a computer or a phone; two slots taking SD, SDHC, SDXC, microSD, microSDHC and microSDXC cards up to 2 TB, with both readable at the same time; data transfer of up to 5 Gbps through a high-performance chipset, and up to 170 MB/s in combination with a UHS-I card, followed by a bracketed note that the 170 MB/s figure is reached only when the card supports that speed too; a compatibility list running from recent iPhones and iPads to Galaxy, Xiaomi, Surface and Dell machines, with a warning that a phone case may prevent the Type-C plug from seating and a recommendation to remove it; plug-and-play with an eject mechanism holding the card firmly in its slot; and a small, light body meant to be carried.

Five gigabits, a hundred and seventy megabytes, and the sentence in brackets

The bracket is the most useful thing on this page.

The second bullet prints two figures — up to 5 Gbps for the link and up to 170 MB/s in combination with a UHS-I card — and then adds, in its own words, that the 170 MB/s figure holds only where the card supports that speed as well.

That is the rule this whole shelf turns on, written by the maker rather than inferred by a reviewer. A card reader sits in the middle of a chain: the card, the reader, the plug, the socket. The slowest of the four settles the outcome, and no figure printed on one link says anything about the other three.

Five of the seven readers in this hub print a rate with no such note. Reading the qualification here is not a criticism of the product; it is the reason to trust the number.

The host side, named by rate rather than by generation

The title names SD 3.0. That is a card standard — it describes what the slot speaks to the card — and it is not the same as the host link.

For the host link the page gives a rate, up to 5 Gbps, and no generation. There is no USB 3.0, no 3.1, no 3.2 anywhere on the listing. Six of the seven readers in this hub name a generation outright.

The practical consequence is small but real: to know what socket to look for, you have to work from the rate rather than read a familiar label off the box.

Two slots, two cards, at the same time

The first bullet publishes something several readers leave implicit. Both slots work at once.

That means a card in each is presented as its own volume, and a copy from the microSD to the SD is one operation rather than two with a swap in the middle. The alternative arrangement — slots that share a controller and take turns — is common and is rarely admitted to on a listing.

Alongside it the bullet names the formats and the ceiling: SD, SDHC and SDXC on one side, microSD, microSDHC and microSDXC on the other, up to 2 TB. No CF, no Memory Stick, no XD. This is a two-format reader and it says so.

A body with no lead, and a warning about phone cases

The fourth bullet makes the case for the shape: plugged straight into the socket, no cable to untangle, nothing bulky. The eject mechanism is named as what keeps the card seated.

The third bullet carries something unusual — an admission. If your phone has a case on it, the maker writes, the Type-C plug may not click home, and taking the case off is recommended for a stable connection.

That is a real limitation of every short, capless Type-C plug and almost no listing mentions it. Publishing it costs the seller something and saves the buyer a return.

Before ordering

Look at the card first: a UHS-I card that is rated well below 170 MB/s is the ceiling of the job, whatever the reader is capable of. Then look at the socket, since 5 Gbps needs a port of that class to mean anything. And if the Type-C end is meant for a phone that lives in a thick case, take the maker’s own warning at face value.

  • Yeemie Pro black multi-card reader with seven slots and an attached USB 3.0 lead

    Yeemie Pro 7-in-1 reader, USB 3.0, seven slots and five cards at once, 5 Gbps stated, LED per slot

    Seven slots and five of them usable together, each with its own green light, on a reader that publishes the gap between those two numbers without ever explaining it.

    Host interface standard
    USB 3.0 — stated in the title and in the first, third and fourth bullets. The third adds backward compatibility with USB 2.0 and 1.1
    Stated link rate
    Up to 5 Gbps — stated in the title and in the third bullet, which puts it at ten times USB 2.0 and gives that older class as 480 Mbps. No megabyte-per-second figure and no card-side rate appears, and no condition is attached to the 5 Gbps figure
    Connector type
    Not published on the listing — neither Type-A nor Type-C is named. The fifth bullet describes a reinforced USB 3.0 cable and a robust heat-resistant connector without giving its shape
    Internal or external form
    External, on an attached lead — described throughout as a reader connected to a computer by its own cable. No bay mounting and no internal header appears
    Slot count
    Seven — stated in the first bullet as one CF slot, two SD, two TF (microSD), one MS and one XD. Seven slots against five cards readable together is a gap the listing prints and never accounts for
    Formats accepted
    CF, SD, SDXC, SDHC, microSD, microSDXC, microSDHC, TF, M2, MS and XD — stated in the second bullet, which names the complete XD-Picture series including Olympus and Fujifilm cards of 1 GB and 2 GB
    Simultaneous slot access
    Five different cards at once — stated in the first bullet as reading and writing five cards at the same time, and again in the title. The third bullet adds that each slot carries its own independent green LED showing its working state
    Stated protocol support
    Not published on the listing — no UHS-I and no UHS-II mode is named, and no SD version number appears. The page lists formats and stops there
    Cable arrangement
    A reinforced USB 3.0 cable, attached — stated in the fifth bullet alongside a robust, heat-resistant connector. No length is published, which is the figure that decides whether a desktop reader reaches the machine under the desk

  • Hama compact 6-in-1 card reader with an SD slot, a microSD slot and a direct USB plug

    Hama 6-in-1 reader, USB 3.0, two slots, SD and microSD families, card-to-card exchange, LED

    A pocket reader whose title counts six and whose bullets count two, with an LED, a direct plug and a card-to-card copy function — and not one speed figure on the page.

    Host interface standard
    USB 3.0 — stated in the title, with the third bullet adding support for USB 2.0 and USB 1.1. The fourth bullet gives the operating systems: Windows 10, 8, 7, Vista and XP, or Mac OS 9.x and later
    Stated link rate
    Not published on the listing — no figure in gigabits per second and none in megabytes per second appears anywhere in the title or the five bullets. It is the only reader on this shelf with no rate of any kind
    Connector type
    Not published on the listing — the second and third bullets both name a direct USB connection requiring no cable, and neither says whether the plug is Type-A or Type-C
    Internal or external form
    External — a compact body with the USB plug built into it, described in the first bullet as small and ideal to carry
    Slot count
    Two — stated in the second and third bullets, both of which call it a 2-slot solution. The title calls the reader 6-in-1, and the six is the number of card formats named rather than the number of slots. The listing prints both figures and never says which is which
    Formats accepted
    SD, SDHC, SDXC, microSD, microSDHC and microSDXC — the six named in the second bullet, which is where the 6-in-1 of the title comes from. No CF, MS or XD format is claimed
    Simultaneous slot access
    Stated indirectly — the third bullet says the reader allows data to be exchanged directly from one memory card to another, which is an operation that needs both slots live at the same time. The words “simultaneous access” are not used
    Stated protocol support
    Not published on the listing — no UHS-I and no UHS-II mode is named, and no SD version number is quoted
    Cable arrangement
    No cable — stated twice, in the second and third bullets, both of which name the direct USB connection as the reason no lead is needed. No length is given because there is nothing to measure

  • Lexar Multi-Card 2-in-1 card reader with an SD slot and a microSD slot in a compact body

    Lexar Multi-Card 2-in-1, USB 3.1, SD and microSD, UHS-I and UHS-II, 312 MB/s stated

    Two slots, two figures and two bus modes: the only reader on this shelf that names UHS-II, and the only one whose two published rates describe two different classes of card.

    Host interface standard
    USB 3.1 — stated in the title and in the sixth bullet, which calls it high-speed USB 3.1 technology. No Gen 1 or Gen 2 suffix appears, and those two differ from each other by a factor of two
    Stated link rate
    Up to 312 MB/s — stated in the sixth bullet against the USB 3.1 interface. A second figure of up to 170 MB/s appears in the fourth bullet, attached there to backward compatibility with SD and microSD UHS-I cards. Both are printed on the same page and the listing does not reconcile them; both are reported here as written
    Connector type
    Not published on the listing — neither Type-A nor Type-C is named in the title or in any of the seven bullets
    Internal or external form
    External — the third bullet describes a compact, portable body, light and space-saving, meant for maximum mobility. No bay mounting or internal header is named
    Slot count
    Two — an SD slot and a microSD slot, stated in the first and second bullets
    Formats accepted
    SD and microSD — stated in the first bullet, with the seventh naming UHS-I and UHS-II cards of both shapes. No capacity ceiling is published, and no CF, MS or XD support is claimed
    Simultaneous slot access
    Both slots at once — stated in the second bullet, which describes transferring files from the SD and microSD slots to the computer at the same time
    Stated protocol support
    UHS-I and UHS-II — stated in the seventh bullet, which names support for SD and microSD cards in both modes, and in the fourth, which gives backward compatibility with UHS-I cards up to 170 MB/s. It is the only listing on this shelf that names UHS-II
    Cable arrangement
    Not published on the listing — no lead is described and no length is given. The third bullet sells the body on being compact and space-saving and does not say how it reaches the machine

    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.

    Bay count
    Two — stated in the title and in the first bullet, which describes reading, writing and transferring in parallel between two 2.5-inch or 3.5-inch drives
    Supported drive sizes
    2.5-inch and 3.5-inch — stated in the title and in the first bullet
    Supported drive interfaces
    SATA hard discs and solid-state drives — stated in the title and in the first bullet. 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 CLONE button is held for three seconds to transfer all data from the source drive to the destination without a computer, and notes that the destination must be equal to or larger than the source
    Interface standard
    Two designations are published: the title says USB 3.0 and the third bullet says USB 3.1 Gen 1. Both are printed and neither is withdrawn
    Stated link rate
    Up to 5 Gbit/s — stated in the title and in the third bullet
    Connector type
    Type-C — stated in the title as a USB-C docking station. No cable is named in any bullet
    UASP support
    Stated — the third bullet names UASP, the USB Attached SCSI Protocol, and claims it speeds transfers by up to 20 % against conventional USB 3.0. The same maker’s 2.5-inch enclosure on the enclosures shelf of this site puts the figure at 70 %
    Power supply
    A dedicated 12 V/2.5 A adapter — stated in the fourth bullet, which says it gives a stable supply to both bays and reliable operation even with two demanding 3.5-inch hard discs. It is the higher of the two current ratings published on this shelf
    Per-bay controls
    A single integrated power switch is stated in the fourth bullet, described as protecting the drives while they are connected and removed, with an instruction to switch the unit off before fitting or removing a drive. No per-bay switch and no per-bay indicator is published

    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

    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

    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
