Carry more of your photos, video and everyday entertainment
Samsung T7 microSD gives a compatible device a compact home for photos, recorded video, downloaded media and supported apps. Its microSDXC format and UHS-I interface suit everyday creative and entertainment use, with sequential reads up to 170MB/s when used through a suitable Samsung reader and host. Class 10, U3, V30 and A2 markings help match the card to the device's recording and application requirements.
This is removable memory-card storage for a compatible microSDXC slot. Choose around the files you use and the capacity the host accepts, then follow its formatting instructions. Transfer speed, supported video modes and whether an app can use card storage depend on the device, reader and operating system.

Key Features
More room for the content you carry
A compatible camera, phone or tablet can use the T7 card to extend its removable-storage space. Organise it around recorded clips, photo collections, downloaded entertainment and other files you want available away from a network. Before installation, check the host's supported capacity and file system. Use the device's recommended formatting method and keep another copy of important files before moving or reformatting a card.
Move captured files through the right reader
Samsung rates sequential reads at up to 170MB/s under its internal test conditions. The enhanced connection uses a compatible Samsung microSD reader; an ordinary UHS-I host may deliver lower throughput. The reader, computer connection and file workload all affect transfers. Choosing the right transfer arrangement helps you use the card's capabilities when bringing footage or a large photo collection back to a computer.
Match the recording mode to the speed class
U3 and V30 identify a minimum sustained sequential-writing class for suitable video-recording use. V30 specifies 30MB/s on the UHS bus, which can support compatible4K workflows when the camera's bitrate and card requirements match. Resolution alone does not define every recording requirement. Check the camera's approved card class and capacity for the actual video mode, especially when using high bitrates or extended captures.
Application-rated storage with host support
The A2 classification describes application-storage performance on an appropriate host. It does not make every phone or handheld install all apps and games onto a card. Whether files or software can use removable storage is controlled by the device and operating system. Select the card for equipment that supports its format and workload, then use the host's storage settings to manage supported content.
Choose the correct card interface for gaming
T7 microSD is a UHS-I card. It can suit gaming devices that support that interface, but it is not microSD Express storage for Nintendo Switch 2 game installation. That console requires Express cards for expanded software storage. Confirm the handheld's interface requirement before buying, rather than treating all microSDXC cards as interchangeable. Other supported cameras and mobile devices also need compatible capacity and file-system support.
Protection for everyday handling
Samsung publishes controlled tests for water immersion, temperature, magnetic fields, X-rays, drops and repeated insertion. These durability results help describe the card's intended portable use, with the individual test limits shown in Specs. They are not a promise that every accident leaves files intact, and protection ratings apply to the card rather than an adapter or reader. Keep valuable photos and work backed up separately.
Manage the card within its intended workload
Samsung Magician provides supported authenticity, card-health and management functions, depending on the operating system and connection. The card has a three-year limited warranty for supported use. Continuous recording in dashcams, CCTV, surveillance and other write-intensive applications is excluded, so choose a suitable endurance card for those workloads instead. Normal everyday storage and recording should still follow the host's maintenance and formatting guidance.
Summary
Samsung T7 microSD is a practical choice for compatible everyday photo, video and entertainment storage. Its UHS-I connection, U3/V30 recording ratings and A2 application classification give useful buying criteria. Match those requirements to your device, use a suitable reader for transfers and retain a separate backup.
Samsung T7 UHS-I microSDXC Memory Card
Samsung T7 microSD is a UHS-I microSDXC memory-card family for compatible everyday cameras, mobile devices and handhelds. U3, V30, Class 10 and A2 classifications help match video and application requirements, while transfer results depend on the card, host and reader. A suitable Samsung reader is required for the advertised up-to 170MB/s read performance. Dimensions and weight below describe the card itself, excluding retail and shipping packaging. It is not an Express card for Nintendo Switch 2 software expansion.
| Specification | Details |
|---|---|
| Storage and Performance | |
| Card / interface | microSDXC; UHS-I SDR104 and enhanced UHS-I DDR200 through a compatible Samsung microSD reader. Usable formatted capacity is lower than labelled capacity. |
| Sequential read | Up to 170MB/s under Samsung internal-test conditions using a suitable Samsung reader; actual results depend on the host, connection and card. |
| Sequential write | Advertised family maximum up to 130MB/s under Samsung test conditions. Performance varies with the selected card, host and reader; this is not a guaranteed writing rate for every card. |
| Video / application classes | Class 10, U3, V30, A2. V30: 30MB/s sustained video capture on the UHS bus. A2 classification minima: 4,000 random-read /2,000 random-write IOPS and 10MB/s sustained sequential write on a suitable host. |
| Measurement conditions | Samsung T7 microSD and Samsung microSD reader version 3.0 in a controlled environment. An ordinary UHS-I slot may operate below the advertised transfer speed. |
| Physical Specifications | |
| Card dimensions / weight | 15 × 11 × 1 mm (L ×W ×T); approximately 0.25 g, card only. Retail and shipping packaging are excluded. |
