Great USB at great price
Needed a fast reliable usb stick at affordable price, and Argos was the best place to purchase the one u was looking for.

Very fast, lots of storage,compatibility is good
I bought this to store movies and tv series, it works well with my mobile phone(samsung) and television(lg). When moving files it is very fast to transfer and with 512gb holds plenty of movies and tv. I would recommend this item as I have purchased 2 and both work great.

Faster then expected, good quality, and high capac
This is a neat compact high capacity USB-C flash drive. I bought it to see what would happen if I filled it with music and plugged it into the car. My usage idea flopped, but because of the car, not the flash drive. What did surprise me were the transfer speeds, which peaked at over 1GBs (not Gbs) and even when transferring multiple small files managed around 100MBs - so faster than I'd expected for *real world* use. Because my usage scenario did work out, this is now spare, but it's the first decent capacity/quality USB-C flash drive I own, so I expect it'll get enough use to make it worth while. ***No TrustPilot review of the store/pickup as I no longer trust TrustPilot!***

Easy setup worked out if the box once formatted
Manufacturers own flash drive. Set up very quickly. All good and compatible with Samsung TV
Nomisthewise, 55 - 64, Bridgwater
Ideal for a Macbook Pro
I have several of the Samsung drives, different capacities. They are physically small with a protective end cap and good performance. They can be directly pliugged into a Macbook without an adapter.

Initial thoughts only as not had it long, but hope it lasts. Does what it says on the tin, what more can you say!

Hey JB,
I can advise that this is plugged directly into a USB-C port.
Thanks for using Q&A.
Thanks for this question, Jimmy.
The Type-C™ USB Flash Drive doesn't come with an adapter for a TV, which would need to be purchased separately.
We hope this helps.

Hello RJ,
I can advise the following for the Samsung 400MBs USB-C Flash Drive - 512GB:
This will depend on the phone and its supported USB capabilities, but can be done, yes.
Thanks for using Q & A.
Hello There,
The Samsung 400MBs USB-C Flash Drive - 512GB can record from your television, provided your TV supports USB recording. This flash drive offers fast transfer speeds and ample storage, making it suitable for recording TV shows and movies.
Regarding watching one channel while recording another, this feature depends on your TV's capabilities. Many modern smart TVs, including some LG models, come with a twin-tuner feature that allows you to record one channel while watching another. However, not all TVs support this functionality, so it's essential to check your specific TV model's specifications.
Thank you for using Q&A
