SanDisk Extreme microSD Card vs Transcend microSD Card

Buy the SanDisk Extreme for action cameras, drones and any device that writes 4K video, because its A2 rating and much faster write speed keep bursts and long clips from stalling. The Transcend is the simpler pick for phones, tablets and casual cameras where write speed rarely matters. Owners rate both highly, but the SanDisk's larger rating base and tougher spec sheet make it the safer choice for demanding recording.

• Choose the SanDisk Extreme if you shoot 4K video, burst photos or use a drone or action camera that needs fast sustained writes.
• Choose the Transcend if you mainly need extra storage in a phone, tablet or basic camera and want a plain, reliable card.
