Pros & Cons

Pros

  • ✓ Dual USB-A and USB-C connectors built in, no adapter or cable needed
  • ✓ Up to 400MB/s read and 360MB/s write, roughly 4X faster than USB 3.0
  • ✓ Metal housing shields both connectors and survives pocket and keychain carry
  • ✓ Free Lexar App on iOS and Android handles photo and video backup

Cons

  • ✗ No iCloud content backup support in the Lexar App
  • ✗ 256GB fills fast if you shoot 4K video or RAW photos
  • ✗ 400MB/s trails NVMe-class portable SSDs that hit 1000MB/s or more
  • ✗ Speed claim comes from Lexar internal testing, so real transfers may run slower
