UHS-II Transfer Support

This dual-slot SABRENT reader supports UHS-II SDXC and microSDXC cards, with transfer speeds up to 312MBps. It can transfer through both slots simultaneously, which suits workflows that use standard and microSD media.
The integrated 6-inch USB 3.2 Gen1 Type-C cable avoids a separate cable, and the reader is bus-powered. It works with Windows 8+ and macOS 12+.
Check your computer’s operating system and USB-C connection, and remember that actual transfer speed depends on the card and host; the USB connection supports up to 5Gbps.
Best For: Photographers moving files from SD and microSD cards to a USB-C computer.
| Pros | Cons |
|---|---|
|
|
Choose this reader when your workflow uses UHS-II SD or microSD cards and your computer has USB-C. Its stated 312MBps ceiling is the highest among the compact card readers here, though actual throughput also depends on the card and host.
The integrated cable and dual-slot transfers simplify a desk setup. Before buying, check that your operating system is supported and that your card uses a listed SD format.
USB-C and USB-A Flexibility
SABRENT SD Card Reader USB C & USB A, Micro SD Card Reader, USB 3.0 Dual Slot Memory Card Adapter for Laptop PC Android (CR-BCA2)
The SABRENT CR-BCA2 combines USB-C and USB-A connectivity in one compact SD and microSD reader. Its dual slots cover SD, SDHC, SDXC, microSD, microSDHC, and microSDXC cards, making it a practical bridge between camera media and laptops or PCs.
The USB 3.0 interface supports speeds up to 5Gbps and is backward compatible with USB 2.0. It is plug-and-play on Windows, macOS, and compatible Android devices, with a built-in LED activity indicator.
Check that your Android device is compatible and that the card format is supported before using it for mobile transfers.
Best For: People who move SD and microSD files between newer USB-C and traditional USB-A devices.
| Pros | Cons |
|---|---|
|
|
This is a useful pick when your computers have a mix of USB-C and USB-A ports and your cards are standard SD or microSD formats. The dual connector approach avoids choosing between two host types, while its 5Gbps interface is ample for routine transfers.
If you use UHS-II media, the supplied details do not specify that support, so check the reader’s compatibility before relying on it for a UHS-II workflow.
Angled Connector for Mobile Setups
SMALLRIG SD/TF Dual-Slot Card Reader USB 4.0 312MB/s - 4870
The SMALLRIG 4870 reader has two slots for SD and TF cards and supports simultaneous reading and writing at up to 312MB/s. Its 90-degree USB-C elbow connector is designed to reduce cable clutter, and a built-in magnet lets it attach to supported phone backs for hands-free use.
Compatibility spans Windows, Mac, Linux, Android, and HarmonyOS, with a range of named phones, computers, and tablets. For Android or tablet transfers, allow the file manager to run in the background so the transfer process is not interrupted.
Check your exact device and card format before buying.
Best For: Mobile creators who want a compact SD and TF reader with an angled USB-C connector.
| Pros | Cons |
|---|---|
|
|
Pick the SMALLRIG if you want a reader that can sit directly on a compatible phone and keep the cable connection turned to the side. It combines two-slot transfers with a stated 312MB/s rate, but mobile compatibility is model-specific and Android transfers have a background-process requirement.
Confirm your phone, card type, and app behavior before planning to use it for field transfers.
Compact Dual-Slot USB-A Reader
SABRENT USB 3.0 Micro SD and SD Card Reader (CR-BYMS)
The SABRENT CR-BYMS is a compact, two-slot reader for SD and microSD cards, including UHS-I formats. It supports reading two cards simultaneously and lists transfer speeds up to 5Gbps over USB 3.0, with backward compatibility for USB 2.0 and 1.1.
An LED indicates power and activity, and its plug-and-play design avoids a driver installation. This is a straightforward choice for transferring camera or mobile-device files to a computer.
Its connector type is not specified in the supplied details, so confirm it suits your host before ordering.
Best For: Users who want a simple USB 3.0 reader for common SD and microSD cards.
| Pros | Cons |
|---|---|
|
|
This option fits a basic camera-to-computer workflow if your media is SD or microSD and UHS-I support meets your needs. Simultaneous reading and the activity LED are handy for routine transfers, while the USB 3.0 interface is backward compatible with older USB versions.
The connector type is not clear in the details, so verify it against your computer before choosing it over the USB-C/USB-A model.
Simple USB-Powered Multi-Format Reader
SABRENT SuperSpeed 2 Slot USB 3.0 Flash Memory Card Reader for Windows, Mac, Linux, and Certain Android Systems Supports SD, SDHC, SDXC, MMC/MicroSD, T Flash [Black] (CR-UMSS)
The SABRENT CR-UMSS uses a USB 3.0 connection and supports SD, SDHC, SDXC, MMC, microSD, and T-Flash cards. It is backward compatible with USB 2.0 hosts and draws power from the USB port, so no separate power supply is needed.
Plug-and-play operation also avoids driver installation. This makes it a straightforward reader for people working across several common card formats on Windows, Mac, Linux, or certain Android systems.
The Android support is limited to certain systems, so verify device compatibility before planning phone-based transfers.
Best For: Users who need one inexpensive reader for SD, MMC, microSD, and T-Flash cards.
| Pros | Cons |
|---|---|
|
|
Consider this reader if you need its mix of SD, MMC, microSD, and T-Flash support and your host can use its USB connection. USB power and plug-and-play setup keep the arrangement simple.
The details do not state a transfer rate or connector type, and Android support is qualified to certain systems, so check those points if speed or phone compatibility is central to your workflow.
Broad Legacy Card Format Coverage
SABRENT 75 in 1 Multi Flash Media Card Reader/Writer(with Power Cord) (CRW-UINB)
The SABRENT CRW-UINB is a six-slot reader that supports 74 different types of memory cards, including M2, XD, SD, microSD, CompactFlash, and Memory Stick formats. Some cards may require an adapter.
It also includes a USB 2.0 port and an internal power connector intended to provide sufficient power for external USB devices. This is better suited to a desk setup with a collection of card types than to someone seeking a fast modern USB-C workflow.
Check the exact card format and adapter requirement before buying.
Best For: Users with older or less common memory cards who need broad format support at a desk.
| Pros | Cons |
|---|---|
|
|
Choose this reader when your archive spans older formats such as XD, M2, CompactFlash, or Memory Stick alongside SD cards. Its broad coverage is the point; the USB 2.0 interface makes it a less suitable match for a workflow centered on fast transfers from current high-speed cards.
Identify the exact card format first and check whether it needs an adapter.
On-Device Playback Screen
Muddy CRV3 HD SD Card Viewer - Durable Water-Resistant Hunting Outdoor SD Card Reader/Viewer with 4.3" LCD Screen & Headphone Jack for Audio - Supports up to 32GB
The Muddy CRV3 is an SD card reader and viewer with a 4.3-inch color LCD screen, headphone jack, and 1080p video playback. Its intuitive menu is designed for direct viewing, which can be useful for checking media away from a computer.
The SD card slot supports cards up to 32GB. This is a specialized option for on-device playback rather than a general-purpose high-speed card reader: the details do not specify its computer connection or supported video formats.
Check that your card capacity and media files are compatible before relying on it in the field.
Best For: Outdoor users who want to view supported SD card photos or video without a computer.
| Pros | Cons |
|---|---|
|
|
This is the niche choice for outdoor use when seeing media on a built-in screen matters more than connecting to a computer. The 4.3-inch display, headphone jack, and 1080p playback make it a viewer as well as a reader, but the SD capacity ceiling is 32GB.
Confirm your card size and video format, and check whether it can also transfer files to your intended computer if that is part of the job.
How to Choose Memory Card Readers
How We Picked Memory Card Readers
This roundup focuses on distinct card-reader jobs: routine SD and microSD transfers, newer USB-C or mixed-port connections, UHS-II workflows, legacy card archives, and direct viewing outdoors. The included products cover those different needs without repeating the same SABRENT internal 3.5-inch reader model as a separate pick.
Card formats and host connections are the first checks. SD and microSD readers suit common camera media, while the CRW-UINB adds formats such as XD, M2, CompactFlash, and Memory Stick.
The CR-BCA2 has both USB-C and USB-A, whereas the USB-C-only CR-CSDM is aimed at newer hosts and UHS-II cards.
Comparing Memory Card Readers by Speed and Connection
The CR-CSDM and SMALLRIG 4870 both give a stated rate of up to 312MBps or 312MB/s, but they address different setups: the former has an integrated USB-C cable and UHS-II SDXC support, while the latter has a 90-degree connector and magnetic phone attachment. USB interface figures describe the connection ceiling, not a guaranteed card transfer speed.
The CR-BCA2 and CR-BYMS use USB 3.0 for common SD and microSD transfers. The CR-BCA2 is the more flexible fit for switching between USB-C and USB-A hosts; the CR-BYMS specifies UHS-I and simultaneous reading, but leaves its connector type unclear.
The CR-UMSS adds MMC and T-Flash coverage, with its Android compatibility qualified to certain systems.

Choosing a Reader for Camera Cards and Legacy Media
For current camera workflows, match the reader to the card type and the host port. UHS-II cards call for a reader that explicitly supports that standard, such as the CR-CSDM.
Standard SD and microSD users have several options, so port convenience and simultaneous slot access may matter more than an interface’s top rate.
A photo archive with older cards calls for a different checklist. The CRW-UINB has six slots and broad support for formats including CF, XD, and MS, but some cards may require an adapter and its host interface is USB 2.0.
Confirm the exact card type before choosing a multi-format reader; broad compatibility labels do not guarantee every card fits directly.
When a Memory Card Viewer Makes Sense
A screen-equipped SD viewer serves a different purpose from a compact computer reader. The Muddy CRV3 can show media on its 4.3-inch LCD and supports 1080p playback, with a headphone jack for audio.
Its slot supports up to 32GB, so check card capacity and file format before taking it into the field.
For phone-based use, pay attention to both the connector and device compatibility. The SMALLRIG 4870 lists specific phone families and a magnetic attachment, while the CR-BCA2 supports compatible Android devices through USB-C or USB-A.
Confirm your exact model, and on Android or tablet transfers with the SMALLRIG, allow the file manager to run in the background.
Who Should Buy Which Memory Card Reader?
Choose the CR-CSDM for a USB-C computer and UHS-II SD or microSD cards. Choose the CR-BCA2 if your devices switch between USB-C and USB-A, or the CR-BYMS if you want a simple dual-slot reader for common cards and UHS-I media.
For a phone-centered setup, consider the SMALLRIG 4870 after checking model compatibility and its background-app requirement. The CRW-UINB suits people working with a mixed collection of legacy formats, while the Muddy CRV3 is the specialized pick for direct outdoor playback.
The CR-UMSS fits users who need its MMC or T-Flash support and a USB-powered plug-and-play reader.
