Transcend JetFlash 350 4GB USB 2.0 Drive

The Transcend JetFlash 350 TS4GJF350 is a 4GB USB 2.0 flash drive built for everyday file transfer and portable storage. Its compact black casing measures 2.4 inches long, 0.7 inches wide and 0.3 inches high. Weighing just 0.30 oz, it suits students and office workers who need a lightweight way to move documents between computers.

Sustained Write Behaviour on USB 2.0

As a USB 2.0 device, the drive reaches its maximum throughput ceiling quickly during large transfers. Sequential write speeds will settle at the bus limit rather than peaking briefly, so copying multi-gigabyte folders takes consistent time per megabyte. The controller manages wear levelling across the 4GB capacity without thermal throttling during extended writes.

Thermals Noise and Power Draw

With no moving parts, the drive runs silently in normal use. Power is drawn directly from the USB port, keeping consumption low enough for laptop ports and unpowered hubs. The small plastic body stays close to ambient temperature even after prolonged read or write sessions.

Questions about this item

Does the TS4GJF350 generate noticeable heat or noise when left plugged in all day?

The drive has no moving parts and draws power only during active transfers, so it stays silent and barely warm even with continuous use.

What host port is required for the JetFlash 350 to function?

A standard USB 2.0 Type-A port supplies both the 5 V bus power and the data connection the drive needs.

Will this 4 GB stick work reliably alongside older USB 1.1 hubs or ports I still use?

Yes, the USB 2.0 interface is backward compatible, so the drive enumerates at low speed on USB 1.1 hosts without extra drivers.
