We try to make a clear list of the best SD cards by comparing performance and evaluating them considering the price and performances. We start from the graphic performance in reading and writing speed.
This above is a graphical comparison of performance (or benchmark) of some SD cards run with CrystalDiskMark 3.0 * in sequential read and write. When we’re buying a new SD cards,we must consider the price and the writing speed , as it is important that the card is as fast as possible in writing the data of the pictures or videos we are recording from the device in order not to fill the buffer causing loss of data or slowing the sequential burst.
Please note that all SD cards in this article are Class 10 and UHS-I (the parameters that are used to classify the speed of SD cards, as we can see in the table below ).
Let’s ideally sort SD cards into:
– PRO (cards with read speed from 60 to 90MB/s or 600x speed)
– PLUS (cards with read speed up to 45MB/s or 300x speed)
– STANDARD (cards with read speed up to 30MB/s or 200x speed)
Which SD card to choose??
- PRO: for high-end dslr reflex, full frame cameras, for those who make sports photography, or generally those who use continuous shooting, timelapse . To shoot videos in FullHD resolution or higher , such as 2K or 4K UltraHD (if the card is classified UHS-I U3).
- PLUS: Adequate for the majority of non-professional purposes, such as reflex, fullframe, landscapes photography, portraits, street and every single-shot use. Movies up to FullHD (with UHS-I devices).
- STANDARD: sufficient for APS-C (not fullframe), compact cameras, movies at resolutions lower than FullHD.
