What the product is

The SanDisk Ultra CZ48 is a 16GB USB 3.0 flash drive with a read speed of 100MB/s. It uses a compact black housing measuring 5.7 x 1.1 x 2.3 cm and weighs 9 g. The drive transfers a full-length movie in under 40 seconds. It is built for everyday file transport between USB 3.0 ports.

Who this suits and who should look elsewhere

This drive suits users who need portable 16GB storage and faster transfers than USB 2.0 provides. Buyers who want more storage capacity should consider other options. Users requiring write-speed guarantees or hardware encryption will not find those features here.

The specification that decides fit

The USB 3.0 interface delivering 100MB/s read speed is the deciding specification. Your host port must support USB 3.0 to reach the advertised transfer rate. Without a USB 3.0 port the drive will operate at the slower USB 2.0 speed.

Questions about this item

How much space does the 5.7 cm by 2.3 cm body need in a USB port?

The drive measures 5.7 cm long, 1.1 cm wide and 2.3 cm thick, so it fits any standard USB-A socket without blocking the next port.

What is the correct way to plug in the USB 3.0 connector so the 100 MB/s speed is active?

Insert the blue USB 3.0 plug fully into a blue USB 3.0 port; a partial insert falls back to USB 2.0 speeds.

When should the 16 GB drive be replaced to avoid data loss?

Replace it if files fail to copy, the drive is not recognised, or after several years of heavy daily writes.
