Lexar 128GB SDXC UHS-II V90 Card

This Lexar Professional SDXC card provides 128GB of storage for photographers and videographers capturing high-resolution images and 4K video. It carries UHS-II U3 and V90 speed class ratings to sustain the write performance demanded by professional camera workflows. The full-size SD form factor fits standard slots in mirrorless, DSLR and cinema cameras.

Installation And Compatibility

Insert the card into any SDXC-compatible UHS-II slot; the interface is backwards compatible with UHS-I devices at reduced speed. A mechanical write-protect switch on the casing prevents accidental data loss during handling. Performance drops to UHS-I limits if the host device lacks UHS-II support, so verify your camera specifications before critical shoots.

Capacity And Speed Headroom

Rated read speeds reach 300MB/s and write speeds up to 260MB/s, allowing extended 4K recording sessions and rapid buffer clearing for burst photography. The 128GB capacity holds thousands of RAW files or hours of high-bitrate footage before offload is required. Sustained V90 performance guarantees minimum 90MB/s write throughput for uninterrupted capture.

Questions about this item

How do I confirm the card is delivering the advertised 300 MB/s read and 260 MB/s write speeds after setup?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-II reader; sustained sequential results near 300 MB/s read and 260 MB/s write indicate the card is performing as specified.

Does the package include the SD reader mentioned in the title or must I buy one separately?

The CYU bundle includes a Lexar USB 3.0 SD reader; no separate reader purchase is required for full UHS-II speed.

Should I choose the 128 GB 2000x V90 card or a lower-capacity version for 4K video work?

The 128 GB capacity combined with V90 and U3 ratings guarantees sustained 90 MB/s write for 4K recording; smaller capacities with the same speed class offer less recording time.
