Manufacturer description
The TEAMGROUP S5 256GB flash drive is a Type-A USB 3.2 Gen 1 thumb drive built for people who move files between desktops, laptops, and older machines without thinking about drivers or software. Read speeds reach up to 140MB/s over the USB 3.2 Gen 1 (also labeled USB 3.1 and USB 3.0) interface, so pulling a folder of photos or a game install off the drive is faster than the USB 2.0 sticks it replaces. It is plug-and-play across Windows, macOS, and Linux machines with a standard Type-A port, with no bundled utility to install first. The body uses COB (chip-on-board) construction, which…
SpecPicks Verdict
SpecPicks scored TEAMGROUP 256GB S5 USB 3.2 Gen 1 Up to 140MB/s Flash Thumb Drive using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. TEAMGROUP's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
How fast is the TEAMGROUP S5 256GB flash drive?
TEAMGROUP rates it at up to 140MB/s over the USB 3.2 Gen 1 interface. A write-speed figure is not published, and real-world speed depends on your host port and file sizes.
Will this work in a USB 2.0 port on an older PC?
Yes. The S5 is a Type-A drive and USB 3.2 Gen 1 is backward compatible with USB 3.0, 3.1, and 2.0 ports, though a 2.0 port will limit transfer speed well below 140MB/s.
Does it work with Mac and Linux, or just Windows?
It is plug-and-play on any computer with a standard USB Type-A port, including Windows, macOS, and Linux desktops and laptops. No driver or bundled software is required.
What is COB tech and why does it matter?
COB is chip-on-board construction: the memory and controller are molded into one encapsulated unit instead of sitting loose inside a plastic shell. TEAMGROUP lists it as the drive's protection feature.
