Manufacturer description

The TEAMGROUP S5 256GB flash drive is a pocket-size Type-A thumb drive built for people who move files between machines all day rather than archive them. It runs on USB 3.2 Gen 1 (backward compatible with USB 3.1 and 3.0) and is rated for read speeds up to 140MB/s, so a folder of photos or a portable app library transfers in a fraction of the time a USB 2.0 stick would take. There is no software to install and no external power to connect: plug it into a computer, laptop, desktop, or PC and it mounts as plug-and-play storage. TEAMGROUP builds the S5 with COB (chip-on-board) construction…

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. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for external storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

How fast is the TEAMGROUP S5 256GB drive?

TEAMGROUP rates the S5 at up to 140MB/s over its USB 3.2 Gen 1 interface. That figure is the read ceiling; real-world speed varies with your port, file sizes, and host system.

Will it work in an older USB 2.0 or USB 3.0 port?

Yes. The USB 3.2 Gen 1 interface is backward compatible with USB 3.1 and USB 3.0 ports, and the Type-A connector fits standard legacy ports, though older ports cap throughput below 140MB/s.

Does it work with a USB-C MacBook or tablet?

Not directly. The S5 is a Type-A drive, so a USB-C port requires a USB-A to USB-C adapter or a hub. It is listed as compatible with computers, laptops, desktops, and PCs.

What is COB technology and why does it matter?

COB (chip-on-board) mounts the memory and controller directly on the board and seals them in one molded body. TEAMGROUP cites it as comprehensive protection, which suits a drive carried loose in a bag.

Is 256GB the only capacity available?

TEAMGROUP lists the S5 line with multiple storage options; this listing is the 256GB version. Check the product listing for other capacities and for current warranty terms.
