Best microSD Cards that are 4K UHD Video Capture Ready

With today’s smartphones, DSLRs and action cameras capable of capturing 4K videos, you need high performing microSD memory cards with high write speed to match.

Not all flash memory cards are created equal.

Most manufacturers advertise the read speed, typically around 45 to 150 MB/s. This is great but when capturing video, you need the write speed to be high and cards with high read speed come does not necessarily come with high write speed. Some have with very slow write speeds of between 10-20MB/s.

Typical write rate for microSD flash memory cards that support 4K Ultra HD video capture is between 60MB/s to 90MB/s or higher.

The only way to tell them apart is from the UHS Speed Class Rating. More common speed rating of U1 is given to cards capable of recording Full HD videos at 1080p or 1920 x 1080 pixel resolution.

MicroSD cards capable of capturing 4K videos or Ultra HD 3840 x 2160 pixel resolution compatible with today’s high end smartphones and premium action cameras have UHS Speed Class 3 (U3) rating.


These cards are 4K Ultra HD ready and will capture 4K Ultra HD resolution videos on your device with no drop frame and not just watch them.

Make sure you choose the right microSD card for your next 4K Ultra HD Home Video ‘Blockbuster’.
