Three USB rates printed, with the unit letters not matching

smartQ C368 multi reader, USB 3.0, CF, SD, MMC and Memory Stick families, four cards at once

The longest format list on this shelf, from CompactFlash down to Mini SD and the Memory Stick family, on a page that prints three USB rates and gets their unit letters into three different shapes.

smartQ C368 black multi-card reader with CompactFlash, SD and Memory Stick slots

smartQ C368 multi reader, USB 3.0, CF, SD, MMC and Memory Stick families, four cards at once

The longest format list on this shelf, from CompactFlash down to Mini SD and the Memory Stick family, on a page that prints three USB rates and gets their unit letters into three different shapes.

Host interface standard
USB 3.0 — stated in the title. The first bullet names three tiers rather than one: Super-Speed, High-Speed and Full-Speed, which are the class names of three USB generations
Stated link rate
Printed as Super-Speed (5 Gpbs), High-Speed (480 MBps) and Full-Speed (12 MBps) in the first bullet. The spellings and the unit letters are the listing’s own and they do not follow one another: the first reads as gigabits, the second and third carry a capital B where the class figures they name are bit rates. All three are quoted here exactly as the page prints them, and none is converted or corrected
Connector type
Not published on the listing — neither Type-A nor Type-C is named in the title or in the four bullets. The title states only that power is drawn over USB
Internal or external form
External and powered over USB — stated in the title, which names USB as the power source. No bay mounting and no internal header is described
Slot count
Not published on the listing as a number of slots. The third bullet gives a working limit instead: up to four different cards can be accessed at the same time. It is the only reader on this shelf that never states a slot count
Formats accepted
CF, SD, SDHC, SCXC, MMC, MMC Micro, RS MMC, Mini SD, Micro SD, MS Duo, MS Pro, MS Pro Duo and MS Pro HG Duo — the second bullet’s list, quoted in the order and the spelling the listing uses, including SCXC where the format family is normally written SDXC. It is the longest format list published on this shelf
Simultaneous slot access
Up to four different cards at once — stated in the third bullet as simultaneous access for simultaneous downloads
Stated protocol support
Not published on the listing — no UHS-I and no UHS-II mode is named anywhere, and no card-side standard is quoted. The page describes formats and never the bus modes behind them
Cable arrangement
Not published on the listing — no lead and no length is described. The title states that power comes over USB, which describes the supply and not the connection

  • The longest format list on this shelf, reaching back to MMC, RS MMC and Mini SD
  • Four cards accessible at once, stated as a working figure rather than implied
  • The three rates are printed with unit letters that do not agree with one another

Best for: A box of legacy cards — CompactFlash, MMC, Mini SD, Memory Stick Duo — that no modern two-slot reader will touch.

On the listing

A SmartQ C368 USB 3.0 multi-card reader, plug and play, compatible with Apple and Windows machines, powered over USB and supporting CF, SD, SDHC, SCXC, MMC and MMC Micro among others; data transfer speeds given as Super-Speed (5 Gpbs), High-Speed (480 MBps) and Full-Speed (12 MBps); support for most standard memory cards including CF, SD, SDHC, SCXC, MMC, MMC Micro, RS MMC, Mini SD, Micro SD, MS Duo, MS Pro, MS Pro Duo and MS Pro HG Duo; simultaneous access to several cards for simultaneous downloads, up to four different cards; and plug-and-play operation with no software required.

Three rates, three shapes of unit

The first bullet is the one that needs quoting exactly, because tidying it would be inventing.

It reads: Super-Speed (5 Gpbs), High-Speed (480 MBps), Full-Speed (12 MBps).

Those three names are the standard class labels for three generations of USB, and the numbers beside them are the figures those classes are defined at. What does not follow is the notation. The first is written with its letters transposed; the second and third carry a capital B against figures that name bit rates. Read literally, the three units are not the same unit.

This page reports all three as the listing prints them. Correcting a maker’s printed figure is how a report quietly becomes a rewrite, and the shelf already carries one listing that prints the same number in two different units within a single page.

What the three tiers do communicate accurately is the fallback behaviour: this reader connects at whatever class the socket provides, and an older port produces an older class.

The format list, which is the reason to buy this

Thirteen names in the second bullet, and several of them have not appeared in a camera for fifteen years.

CF and SD and Micro SD are the modern part. MMC, MMC Micro, RS MMC and Mini SD are the middle era. MS Duo, MS Pro, MS Pro Duo and MS Pro HG Duo are the Memory Stick family, which lived and died inside one manufacturer’s cameras and camcorders.

That list is the longest on this shelf by some distance, and it is the whole argument for this reader. A modern two-slot SD and microSD unit will not touch most of it.

One entry is worth flagging as printed: the list includes SCXC, where the format family is normally written SDXC. The page quotes the list in the maker’s spelling.

Four cards at once, and no slot count at all

The third bullet gives simultaneous access to up to four different cards.

What it does not give — and what no line on this page gives — is how many slots the body actually has. Every other reader in this hub states a number: two, four or seven. Here the working limit stands in for the physical count, and those are not the same thing. A body may hold more slots than it can address at once, which is precisely the arrangement two other readers on this shelf publish.

So the honest reading is: at least four slots, four usable together, and the total unstated.

The bus modes that are never mentioned

No UHS-I. No UHS-II. No SD version number.

For the legacy formats that headline this listing that is irrelevant, since CF and MMC and Memory Stick do not use UHS modes at all. For a modern SDXC card it matters, because a slot with no UHS mode negotiated falls back to the older, slower bus, and the page gives no basis for expecting anything else.

Two readers in this hub name UHS-I and one names UHS-II. This one takes far more formats than any of them and says nothing about the modes behind any of them.

Before ordering

Buy this for the breadth of the format list rather than for a rate, because the rate section is the weakest part of the page. Expect the older bus mode on modern SD cards. And note that the connector shape is never named, so what plugs into the machine has to be confirmed with the seller.

  • Suejezt aluminium multi-card reader with seven slots and an attached USB Type-C lead

    Suejezt 7-in-1 aluminium reader, USB-C 3.1, seven slots and five cards at once, 5 Gbit/s stated

    The Type-C answer to a seven-slot desk reader, in an aluminium shell the maker credits with carrying heat away, and the only listing on this shelf that publishes no manufacturer reference at all.

    Host interface standard
    USB 3.1 — stated in the first bullet as a USB-C 3.1 multi-card reader and again in the second and third, which describe a 3.1 reader on a Type-C 3.1 cable. No Gen 1 or Gen 2 suffix appears
    Stated link rate
    Up to 5 Gbit/s — stated in the title and in the second bullet, which puts it at ten times USB 2.0 and gives that class as 480 Mbit/s. No megabyte figure appears and no condition is attached to the rate
    Connector type
    Type-C — stated in the title and in the first, fourth and fifth bullets. The fifth names it as a reinforced Type-C 3.1 cable
    Internal or external form
    External, on an attached lead — the fourth bullet lists MacBook, iMac, iPad Pro, Surface and Chromebook machines with Type-C sockets as the hosts. No bay mounting is described
    Slot count
    Seven — stated in the first bullet as one CF slot, two SD, two TF (microSD), one MS and one XD. The five-card working figure sits two below the slot count and the listing does not explain the difference
    Formats accepted
    CF, SD, SDXC, SDHC, microSD, microSDXC, microSDHC, TF, MS and XD — stated in the third 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 repeated in the title. The second bullet adds an independent green LED on each slot and a steady green light for normal operation
    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. The page lists card formats and never the bus modes behind them
    Cable arrangement
    A reinforced Type-C 3.1 cable, attached — stated in the fifth bullet. No length is given. The same bullet names a built-in smart chip guarding against overcurrent, overvoltage, short circuit and high temperature, and credits the aluminium housing with carrying heat outwards
    Amazon reference
    B0CD6NYP8B (same reference on 6 Amazon marketplaces)
    EAN
    0671891482604
    • A Type-C lead, which is the plug most recent laptops have and which four readers on this shelf never name
    • An aluminium housing, named with heat dissipation as the reason for it
    • No manufacturer reference published anywhere, so there is no part number to search on

    Best for: A recent laptop with only Type-C sockets, faced with a bag of cards from three different cameras and no adapter to hand.

  • 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

  • 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

  • Xespis network tool kit with crimping tool, cable tester, stripper and punch-down tool in a zipped bag

    Xespis Twelve-piece network tool kit with a three-in-one crimping tool and a tester

    The cheapest way onto this shelf: a bag holding a three-in-one crimping tool, a continuity tester, a stripper and a punch-down tool — described in a bullet that the listing then prints again, word for word, at the bottom of the page.

    Connector positions supported
    The connector families are named and the position counts are not: RJ-11, RJ-12 and RJ-45 appear in the second bullet alongside CAT5, CAT5e and TIA-568A/568B. The 8P8C, 6P6C and 4P4C notation that would say what the dies hold is not printed
    Pass-through capability
    Not published on the listing — the tool is called a three-in-one crimping tool throughout and nothing says whether it trims conductors flush at the front of a plug
    Ratchet action
    Not published on the listing — no ratchet, lock or release is described, and the bullets discuss the contents of the bag rather than the mechanism of the tool
    Integrated stripper
    Not published on the listing as part of the crimping tool — the three-in-one is never broken down into its three jobs. What is stated is a separate stripping tool supplied in the same bag
    Integrated cutter
    Not published on the listing for the same reason — the three functions of the crimping tool are never named, and no cutter is described on the tool itself
    Replaceable blades
    Not published on the listing — no blade is described as removable, and no spare is listed among the contents
    Punch-down tool included
    Yes — an insulation-displacement insertion tool is listed in the first and fifth bullets. No blade type is named for it
    Kit contents
    Three-in-one crimping tool, network cable tester, stripping tool, punch-down tool, 10 RJ45 plugs, 10 protective boots, a crosshead screwdriver, a flat screwdriver, a yellow mini knife, instructions and a tool bag — stated. The same list appears twice, as the first bullet and again as the fifth

    Yavinane Pass-through kit with twenty Cat7 and Cat6a plugs, tester and LSA Plus punch-down tool

    The only kit here whose supplied plugs match the capability of its tool — twenty pass-through plugs given a category and a plating thickness — with a punch-down tool named by its blade family rather than left generic.

    Connector positions supported
    8P8C, 6P6C and 4P4C — stated in the second bullet, alongside RJ45, RJ12 and RJ11. It is one of two kits on this shelf to print the position notation
    Pass-through capability
    Yes — stated in the title and in two bullets, where the pass-through design is credited with letting the wiring be checked twice and with preventing accidental contact between conductors
    Ratchet action
    Not published on the listing — no lock, ratchet or release is described anywhere in the five bullets
    Integrated stripper
    Not published on the listing as part of the crimping tool — the tool is called a three-in-one crimping tool without its three jobs being named. A separate stripping tool is supplied in the bag
    Integrated cutter
    Not published on the listing for the same reason — a separate wire cutter is listed among the contents, and no cutting function is described on the crimping tool itself
    Replaceable blades
    Not published on the listing — no blade is described as removable and no spare is included
    Punch-down tool included
    Yes — an LSA Plus punch-down tool is listed in the first bullet, named by its blade family rather than described in general terms
    Kit contents
    One RJ45 crimping tool, 20 pass-through plugs stated as Cat7 and Cat6a, 20 boots, one stripping tool, one wire cutter, one LAN tester, one LSA Plus punch-down tool and a zipped bag — stated. The third bullet gives the plug contacts a gold plating of 50 microns

  • BENFEI black dual-bay drive docking station with a clone button and a power switch

    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
