Frequently asked questions
What is a good price per GB for a memory card?
In 2026, a good price per GB for an SD or microSD card is around £0.05–0.10/GB for standard cards and £0.10–0.20/GB for high-speed UHS-II or V60/V90 cards. Larger capacities (256GB+) usually offer better value per GB.
What do SD card speed ratings mean (Class 10, U3, V30)?
Speed ratings indicate minimum write speeds: Class 10 = 10MB/s, U3 = 30MB/s, V30 = 30MB/s, V60 = 60MB/s, V90 = 90MB/s. For 4K video, use V30 minimum. For 8K or high-bitrate video, use V60 or V90.
What memory card do I need for my camera?
For casual photography, U1/Class 10 is fine. For burst RAW or 4K video, choose U3/V30 or higher. Check your camera manual for supported formats (SD, CFexpress, etc.) and maximum capacity.
What microSD card should I buy for Nintendo Switch?
Nintendo recommends UHS-I cards with transfer speeds of 60–95MB/s. A 128GB–512GB microSD is ideal for most users. SanDisk, Samsung, and Lexar are reliable choices.
What is the difference between SD, microSD, and CFexpress?
SD cards are used in most cameras and laptops. microSD cards are smaller and common in phones, drones, and Nintendo Switch (with an adapter for SD slots). CFexpress and CompactFlash are professional formats for high-end cameras and fast burst/video work.
How much does a 1TB microSD card cost?
A 1TB microSD card typically costs around £60–120 depending on brand and speed class. Use our comparison table to find the current cheapest 1TB options.
