Capacity and interface

The SanDisk Ultra CZ48 provides 32GB of storage and connects through a USB 3.0 port. It is suited to students, office workers and photographers who need to move documents, photos or media between computers quickly. The small black casing fits easily in a pocket or bag. Buyers who require more than 32GB of space or a USB 3.1 or 3.2 connection should look elsewhere.

Sustained transfer behaviour

The drive is rated for a read speed of 100MB/s, allowing a full-length movie to be transferred in less than 40 seconds. Write speeds are lower and will vary with file size and host controller, so very large batches of small files take proportionally longer. The USB 3.0 interface delivers up to ten times the throughput of a USB 2.0 drive during extended copies.

Deciding specification

The single figure that determines suitability is the 100MB/s read speed combined with the 32GB capacity. If your workflow demands faster sustained reads or a larger single volume, this model will not meet the requirement.

Questions about this item

Does the CZ48 get hot or draw much power when I leave it plugged in all day?

The SanDisk Ultra CZ48 has no moving parts and draws power only during active transfers, so it stays cool and uses minimal bus power during continuous use.

What port must my computer already have for the CZ48 to reach its 100MB/s read speed?

Your computer needs a USB 3.0 port; the drive will work in USB 2.0 ports but will be limited to slower speeds.

Will the CZ48 work reliably alongside the USB 2.0 flash drives and older peripherals I already use?

Yes, the CZ48 is backward compatible with USB 2.0 ports and hubs, so it operates alongside your existing drives without conflicts.
