Frequently Asked Questions
Is this listing for one card or two, and how much storage do I get?
It is a two-pack, with each card offering 128GB of microSDXC capacity. Note that rated storage counts 1GB as one billion bytes, so usable space is less.
Is this card fast enough to record 4K video reliably?
Kortrifess rates it U3 and V30, the grades associated with sustained 4K UHD capture. However, the listing publishes only an 80MB/s read speed and does not state a write speed.
What does the 80MB/s speed rating actually cover?
That figure is the read, or offload, speed used to move files to a computer. Kortrifess notes it requires a compatible device and may be lower depending on your host hardware.
How durable is this card for outdoor and travel use?
Kortrifess lists it as shockproof, IPX6 waterproof, X-ray proof, and magnet-proof, and rates it to operate across a -10°C to 80°C temperature range.
What devices is this card designed to work with?
The listing cites smartphones, tablets, drones, and action cameras, and highlights camera and drone 4K UHD and Full HD video recording as primary uses.
What is the A2 rating on this card meant to indicate?
A2 is an app performance class geared toward faster app-related read and write operations, one of several ratings Kortrifess assigns alongside Class 10, U3, and V30.
