Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonGreat value for The money. Works exceptionally well. Fast transfer times in a small product. Compact and easy to use. And that's well, has great data integrity and security. The item is very light. Connects well to a computer with a USB C port. I highly recommend this item.
I clearly waited way too long to upgrade my storage as my flabbers are absolutely gasted at how fast things can transfer on a quality product like this one! Really.
I am a photographer as a side hobby and between that and just being a typical mom in 2026, my phone runs out of space extremely fast! Clearing out has always been an absolute pain...until discovering this.
It is incredibly convenient, as it plugs directly into my S25 Ultra.
It's really wild if I stop to think about it, it stores half a terabyte of data while being this tiny, super lightweight thing. It takes up nearly no space, so best to put a lanyard on it so as not to lose it.
I have run into no issues. It transfers even large files at a very fast rate. All files are transferred with no corruption, no interruption, no lag.
I will absolutely be buying this again when my next cleanup is needed.

I use my phone for video camera work. For context, I bought a 1TB phone specifically because of that. I may take 250-300GB of video in one weekend. MTP is far too pathetically slow method to transfer such large amounts of video from my phone to my PC, and Cloud methods are not really any better. So, for such situations I usually use a portable media device such as flash drive or external NVMe to do the transfer. Copy it from my phone to the flash drive, copy off of the drive onto my PC. Fastest method by far.
I have lately been using a NVMe USB enclosure for this purpose, but due to NVMe's (relatively) high power draw, I have to use a USB dongle with power input while making the transfer. Not the end of the world but far from convenient. In the past I have experimented with other USB-C drives, but they've all been far too slow in the write department to be realistic. You may have 300MB/s of read but if your write speed is a paltry 21-22MB/s, you're as good as useless for me. This was the case for the older Samsung USB-A flash drives, and even the newer USB 3.1 gray ones.
This one, by contrast, is still not amazing on writes which is to be expected for a traditional flash drive, but it is FAR better than any USB-C drives I have used in the past. On very large transfers (100+GB) it usually settles down to around 75-80MB/s within the first 30 seconds or so, and stays at that speed for the entire transfer. Doesn't get too hot (just warm) and works well.
Reads are excellent so far. On Windows I'm getting around 365MB/s continuously. The only real issue with this drive is on very large reads, it will overheat. It gets quite hot on these high speed reads and after around 75-80GB, mine disconnected and stopped the transfer. Thankfully Windows seems pretty good about file management and after it sits for a while and cools down, hitting Try Again seems to work reliably.
Overall very happy with this drive. It's pretty darn small for 256GB, and fast enough that I can deal with it for the convenience of not needing to use any dongles.

I purchased these so that I could use my existing USB-A flash drives with toy M5 MacBook Air which only has USB-C ports. They work well enough, my only issue is there is a slight gap that makes it longer with a flash drive plugged into it. Not sure if it could be engineered to reduce that gap and keep the total length when in use as small as possible. In any event, these allow me to use nearly 1/2 dozen USB-A flash drives that I have had for a while, as well as if someone else wants to share something on one of their USB-A drives. For what I use them for, I do not notice any speed issues. They are durable and easy to carry in my laptop bag.

I am really impressed with the Samsung Type‑C USB flash drive I ordered. The transfer speeds are excellent, and it works instantly with all my USB‑C devices. The build quality feels solid and durable, and the compact design makes it easy to carry. It’s perfect for backing up photos, moving files between devices, or expanding storage on the go. Highly recommend for anyone who needs a fast and dependable USB‑C drive. Great price too!!!
To say this thing is tiny would be an understatement, but it works amazingly well. Transferring data from my computer or phone is extremely fast and easy, and the amount of space allows for storage of huge amounts of data. I used one to back up my entire work laptop, and I use a second one to back up all the photos on my phone. If you're using an Android phone, it's as easy as plugging it into the port and it is immediately recognized as a storage device, especially on Samsung devices.
If I had an issue, it would be the tiny cap that comes with it. The entire package is tiny, and the cap is even smaller. There are small loop holes on both the item and the cap, but it's so small that not much will fit through it. I ended up using some thick hobby thread to tie the cap to the device so I won't lose the cap. Of course, it is probably fine to use without the cap.
A word on durability: I accidentally washed one of them in a pocket of my pants. It went through the entire cycles of the washer and dryer, and worked perfectly afterwards. While I would not recommend doing this to your important stored media, it is reassuring to know that liquids like rain or coffee spilled at your desk is unlikely to harm it.
Fast, small and works everywhere. Super redundant, super durable.
Gloriously tiny and so far no problems at all.
Very fast delivery.
Good packaging and safely delivered.
Small device and works perfectly with my Samsung phone.
