The SanDisk Extreme Go 128GB USB 3.1 Flash Drive in Black — up to 200 MB/s reads and 150 MB/s writes, retractable connector, plug and play on Windows and Mac. Genuine SanDisk, brand new.
- ✓ USB 3.1 speed — gigabytes in seconds, fast writes too
- ✓ 128 GB — photos, 4K video and backups on a keyring
- ✓ Retractable connector — no cap to lose, pocket-safe
A flash drive only earns its keep twice: the moment you copy to it, and the moment you plug it into someone else’s machine. The SanDisk Extreme Go 128GB is built for both — up to 200 MB/s reads and 150 MB/s writes over USB 3.1, in the retractable black housing SanDisk has been refining for a decade. Brand new, genuine SanDisk stock.
Speed
200 MB/s reads, 150 MB/s writes
This is the difference between a coffee-break transfer and a blink. A 4K film, a wedding shoot, a project folder — USB 3.1 speeds move gigabytes in seconds, and the fast write side is what separates the Extreme Go from everyday drives that crawl when you copy TO them.
Capacity
128 GB in your pocket
Room for tens of thousands of photos, hours of 4K footage or a full working backup — enough that the drive lives on your keyring as a portable archive, not a shuttle you have to keep emptying.
Built to travel
Retractable connector, no cap to lose
The USB connector slides back into the housing when you are done — no cap rolling under the desk, no exposed pins collecting pocket lint. Plug and play on Windows and macOS, straight out of the box.
Right choice if you…
✔ Move big files often — video, RAW photos, project archives
✔ Want fast WRITE speeds, not just a fast-sounding read number
✔ Plug into many machines — USB-A works everywhere, no dongles
✔ Want genuine SanDisk, brand new
Consider something else if…
✖ Your laptop is USB-C only — browse our Type-C storage range
✖ You need it for a phone or camera slot — you want a microSD card instead
✖ You only shuttle documents — a standard drive does that for less

Frequently Asked Questions
Will I really see 200 MB/s?
Those are SanDisk’s rated peaks over a USB 3.1 / 3.0 port with large files. Many small files, or an old USB 2.0 port, will run slower — that is physics, not the drive. On a modern port with big files, it is dramatically faster than standard drives.
Does it work with both Windows and Mac?
Yes — it comes formatted to work with both out of the box, no drivers needed. Plug it in and it appears.
Is this USB-A or USB-C?
USB-A — the full-size connector that fits desktops, laptops, TVs and car stereos. If your machine only has USB-C ports, look at our Type-C storage range instead.
What makes it “Extreme Go” rather than a standard SanDisk drive?
Write speed. Standard drives read quickly but crawl when copying to them; the Extreme Go’s up-to-150 MB/s writes make it practical for 4K video and bulk backups, not just handing files around.
Is it genuine SanDisk?
Yes — brand new, genuine SanDisk stock in retail packaging. Counterfeit flash drives with fake capacities are common on marketplaces; every listing we sell is the real part.
