Overview
A 256GB microSDXC card rated for reads up to 160MB/s, aimed at phones, action cameras, and drones that need steady 4K recording rather than one headline speed number.
Four separate ratings sit on this card: A2 for app performance, V30 and U3 for sustained video bitrate, and C10 for a speed floor, together pointing to steady 4K capture rather than raw burst speed. Lexar notes that the advertised 160MB/s peak needs one of its own USB 3.1 readers to reach, so real-world speed in a phone or camera slot will run lower. It ships with a full-size SD adapter, which matters for gear that only accepts that format.
- 256GB, UHS-I, rated up to 160MB/s read
- Includes a full-size SD adapter
- 10-year warranty, lifetime Lexar Recovery Tool access
Who it's for
Suits anyone filling a phone, tablet, dashcam, or drone that shoots 4K and needs to avoid dropped frames from a slow card. Not the pick for someone chasing the fastest possible transfer speed off the card itself, since that ceiling depends on Lexar's own reader.
Pros and cons
- V30/U3 rating supports sustained 4K recording
- 256GB fits long clips or a large photo library
- IPX7 water resistance and shock rating for field use
- 10-year warranty plus lifetime recovery tool access
- 160MB/s peak needs a specific Lexar reader, not typical slots
- Capacity is billed in decimal gigabytes, so usable space reads lower
- No performance claims for write speed on its own
Performance notes
UHS-I signaling and the A2 rating are what let a phone load apps off the card quickly, while V30 and U3 guarantee a minimum sustained write speed so 4K footage does not stutter or drop frames mid-recording. The 160MB/s figure is a best-case read number reached only with Lexar's matched reader; an ordinary phone, camera, or laptop slot will read and write slower than that.

Frequently asked questions
Will this card really hit 160MB/s in my phone?
Only with Lexar's own 2-in-1 USB 3.1 reader; speeds in a phone or camera slot will be lower.
Is 256GB enough for 4K video?
The V30 rating guarantees a sustained write speed built for 4K capture, so clips should record without dropped frames, though total footage length still depends on your camera's bitrate.
What if I accidentally delete files from the card?
Lexar includes lifetime access to its Recovery Tool software to retrieve deleted or formatted data.
