JetFlash 780 256 GB USB 3.0 drive

The Transcend JetFlash 780 is a 256 GB USB 3.0 flash drive built with MLC NAND for high endurance. It targets users who need fast portable storage for large files and frequent transfers. The drive works with any USB 3.0 or USB 2.0 port and requires no external power.

Transcend Elite software and checkerboard casing

The bundled Transcend Elite download adds backup, encryption and restore tools for managing data on the drive. The checkerboard-pattern housing provides a distinct grip and resists fingerprints during daily handling.

Questions about this item

Will the MLC flash memory in this TS256GJF780 need replacement after heavy daily writes?

The drive uses MLC NAND which endures more program/erase cycles than TLC, so the memory itself should last years under typical workloads; no user-replaceable parts exist.

Does the 140 MB/s write speed hold steady during long transfers or does it drop?

Sustained write performance will fall below the 140 MB/s peak once the SLC cache fills; the exact floor depends on file size and host controller.

How warm does the metal casing get and does it draw extra power when running all day?

The USB 3.0 interface supplies all power — no external adapter — and the aluminium body acts as a heatsink, so it stays warm but within normal operating limits during continuous use.
