128 GB USB 3.0 flash drive

The SanDisk Ultra Flair SDCZ73-128G-G46 is a 128 GB USB 3.0 flash drive with a Type A connector and a black metal casing. It provides portable storage for documents, media and backups. The drive includes 128-bit AES encryption with password protection for private files. It suits anyone who needs quick, secure file transfers on computers with USB 3.0 or USB 2.0 ports.

USB 3.0 interface limits

The drive uses the USB 3.0 standard, which is backwards compatible with USB 2.0 ports. On a USB 2.0 connection the transfer rate will fall to the older standard's maximum, so the advertised speed advantage is lost. The metal casing helps dissipate heat during sustained writes, but the drive has no active cooling and can throttle under continuous heavy load. No driver installation is required on modern operating systems.

128 GB capacity and headroom

The 128 GB capacity holds thousands of photos, hours of video or large project folders with room to spare. Sequential read speeds reach up to 150 MB/s, while the supplier notes up to 130 MB/s for typical transfers. Write speeds are lower and will vary with file size and host controller. Very large single-file writes or sustained bulk transfers may run into the flash memory's write-endurance limits over time.
