Frequently Asked Questions
What is a good price per GB for an SD card?
In 2025, a good price per GB for an SD 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+) offer better value per GB. Budget microSD cards can go as low as £0.04/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. For photos and general use, U1/Class 10 is usually sufficient.
What SD card do I need for my camera?
For casual photography, a U1/Class 10 card is fine. For burst shooting or RAW photos, choose U3/V30. For 4K video, use V30 minimum. For professional 4K/8K video, use V60 or V90. Check your camera's manual for recommended specs and maximum supported 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 card is ideal for most users. SanDisk, Samsung, and Lexar all make reliable cards. The official Nintendo-branded cards are just re-labeled SanDisk cards at a premium price.
