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

Great deal!

These are always my go to SD cards for my drones and have never failed for data transfer for read/write speeds.

I use it for my drone. It works.

I purchased 3 of these cards. The first thing I did was test them with f3write and f3read at the bash console to verify their advertised capacities. Fortunately for the seller, the results of the tests confirmed that 60 GiB (i.e., 64 GB) were written and read from these cards. The capacity test is more revealing than the speed test since bogus cards have had their microcontrollers reprogrammed to report larger capacities than what they are capable of.

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.

This is a great solution to solving backups. Let’s say you have a server that has to backup every night at 1. It dumps into the cloud or onto a raid server for the backup.

Works as advertised.

Works great. No complaints

I needed more memory so that I can keep my

Great card the micro format has never let me down.
