Capacity and interface

The SanDisk Cruzer Ultra SDCZ48 is a 16GB USB 3.0 flash drive designed for users who move large media files between computers. It provides enough space for HD videos, photo libraries and work documents while remaining small enough for a key ring.

Sustained transfer behaviour

Read speeds reach up to 100 MB/s when the drive is connected to a USB 3.0 port, and write speeds are up to five times faster than a standard USB 2.0 drive. Performance remains consistent during long file copies rather than dropping after an initial burst.

Thermals noise and power

The drive has no moving parts and draws power directly from the USB port, so it runs silently and adds negligible load to the host system. Its compact plastic body stays cool to the touch during normal operation.

Questions about this item

How much power does the 16 GB USB 3.0 drive draw when it is transferring files all day?

The drive is bus-powered from the USB port and consumes only the standard current allowed by the USB 3.0 specification, so it adds negligible load to a laptop or desktop running continuously.

What port must my computer already have for the SanDisk Cruzer Ultra to work at its rated speed?

A USB 3.0 Type-A port is required to reach the quoted 100 MB/s read speed; the drive will still function in a USB 2.0 port but at the slower 2.0 transfer rate.

Will the 16 GB USB 3.0 flash drive work reliably alongside my older USB 2.0 peripherals on the same hub?

Yes, the drive is backward compatible with USB 2.0 ports and hubs, so it can share a hub with older devices without causing conflicts or slowing down the other connections.
