Memory cards and card readers
Memory cards and card readers include microSD cards, SD cards and devices for accessing stored files, with brands such as Kingston, Intenso, Imro and Transcend. They suit people storing photos, recording video or transferring documents. Choose a card by the format, capacity and speed class supported by your device, and a reader by its supported card formats and computer connection.
Memory cards and card readers provide storage for photos, videos and other files, alongside a way to access and transfer that data. The range covers microSD memory cards, SD memory cards and card readers. Brands include Transcend, Sandisk, Intenso, Lexar, Kingston, Philips, Imro and Goodram. Some microSD cards come with an SD adapter for use in a suitable slot.
How to choose memory cards and card readers
Check the exact device model for its supported card format, maximum capacity and required speed class. Then consider whether the card will mainly hold photos, record video or move files between devices. Advertised read speed and speed class describe different aspects of performance, so a single speed figure should not determine the choice.
- Card format: microSD and SD cards have different physical sizes. Choose the format that matches the device slot rather than selecting by storage capacity alone.
- Storage capacity: consider the number of photos, length of videos and size of other files you expect to store. Higher capacity provides more storage when supported by the device.
- Speed markings: product descriptions include Class 10, UHS-I, U1 and V10 markings. For video recording, consider the required write-speed class as well as any stated read speed.
- SD adapter: selected microSD cards include an adapter for an SD slot. Check the individual product contents to establish whether an adapter is supplied.
- Card reader: match the reader to the card format and the connection available on your computer. A reader is useful for accessing stored files and transferring them.
The microSD memory card, SD memory card and card reader subcategories separate the main product types. For everyday photo storage, video recording and file transfers, base your choice on storage needs, recording requirements and how you intend to access the data.
