What to know before buying

Usable space may be below the stated capacity after formatting. Devices must support external storage above 32GB. The listing says formatting on a device without that support can limit the drive to 32GB, with partition recreation in a computer's Disk Management offered as the recovery method.
The listing describes security software with 256-bit AES encryption, but explicitly does not guarantee complete protection from unauthorised access or data loss.

Listing details to confirm

The stated maximum read speed is a claim, not a guaranteed transfer rate. Lexar says performance varies with the host, interface and usage. Its full 5Gbps requires USB 3.2 Gen 1 support on both the computer and cable, while USB 2.0 falls back to 480Mbps.

Who is it for?

A good fit for

People who need a small USB-C drive for files or photo backup on compatible phones, tablets and laptops.
Buyers who can use a USB-C connection and want a stated capacity of 64 GB.

Less suited to

People needing USB-A connectivity, which is not listed for this drive.
People who require confirmed iCloud backup or guaranteed transfer speeds.
