Is this card fast enough for 4K video?

It is rated for 4K UHD capture on cameras that support UHS-I cards, but its write speed is modest. For sustained high-bitrate or high-frame-rate 4K, a V60 or V90 card is safer.

Does it work in a mirrorless camera?

Yes, it fits any camera with an SD slot and supports UHS-I. It is best suited to stills and moderate video rather than fast continuous bursts.

How many photos fit on 128 GB?

That depends on file size. Expect roughly several thousand JPEGs or a few thousand RAW files from a mid-range DSLR, plus hours of compressed 4K video.

No. It is a UHS-I card, so it will not reach UHS-II speeds even in a UHS-II slot. It is backward compatible with UHS-I devices.

The card itself. It carries Lexar's lifetime limited warranty.

Should I buy this or a V30 card?

A V30 card guarantees a minimum write speed suited to steady 4K recording. This card is fine for photos and lighter video but less predictable under sustained writes.

Our take on the Lexar BLUE Series High-Performance 800x PRO SDHC/SDXC UHS-I Card (128 GB)

The Lexar High-Performance 800x PRO is a UHS-I SD card rated for up to 150 MB/s reads, aimed at point-and-shoot cameras, mid-range DSLRs and HD camcorders. The 128 GB capacity holds a large number of photos and 4K UHD clips, and the card is sold with a lifetime limited warranty. It is a budget-friendly UHS-I option rather than a UHS-II or V60/V90 card, so it suits casual and enthusiast shooting more than sustained high-bitrate video or burst-heavy sports work.
