SanDisk Extreme Pro Micro SDXC UHS-I U3 A2 V30 Memory Card (256GB)

fast shipping and works fine on 4K

My test might have been maxed out by my USB card read/writer. Still comparing it to a Samsung EVO 128gig (which cost less than this 64 gig) the only benefit is the sequential Writes are about 50% better. Random was bout the same.

Not sure if big difference with extreme version but has held up so far.

No concerned with read speed much. Im a fpv 4k drone user and Ill update how it looks compared to my old onn one. My father saw some inconsistencies with it so Im pretty sure this with be better at 130 140 write speed. This test was done on an ASUS ROG STRIX 2021 G513QY......

This works perfect for my Brave 4 4k action camera...

I bought the SanDisk Extreme Pro MicroSDXC UHS-I U3 A2 V30 256GB Memory Card to use with my GoPro Hero9 Black. So far, Ive been EXTREMELY SATISFIED with its performance.

Great Card...Great Capacity for the price too. Will always look to SanDisk for my video and photo work

Great card the micro format has never let me down.

I bought this for my drone 4K video and 48 megapixel photos. Good, high quality and fast transfer speeds.

Its a scan disk what else is there to say
