Dual-connector utility

The SanDisk Ultra Dual USB Drive 3.0 provides 128GB of storage with both USB-A and micro-USB interfaces. It suits users who move files between computers and Android devices without cloud sync. The drive is new and weighs .01 pounds.

Sustained throughput

Sequential read and write speeds are each rated at 150MB/s over the USB 3.0 connection. Large transfers hold this rate longer than burst-only designs. The lightweight build keeps latency low during extended copy sessions.

Thermals and power

The compact enclosure measures 1.44 L x 0.78 W x 0.43 H inches and draws power directly from the host port. No active cooling is present, so surface temperature rises under continuous load. Operation stays silent in normal use.

Questions about this item

Does the 150 MB/s read speed generate noticeable heat during all-day transfers?

The drive weighs 0.01 pounds and measures 1.44 by 0.78 by 0.43 inches, so it stays cool to the touch even during sustained 150 MB/s read or 150.0 MB/s write activity.

What host port do I need to reach the 150 MB/s read and 150.0 MB/s write rates?

A USB 3.0 Type-A port is required; the drive plugs directly in with no extra cable or power adapter.

Will the USB 3.0 interface slow down if I keep using my older USB 2.0 hub?

Yes, the 150 MB/s read and 150.0 MB/s write speeds drop to USB 2.0 limits when connected through a 2.0 hub, but the drive remains fully functional.
