Samsung Type-C 512GB USB 3.2 Gen 1 Flash Drive, 400MB/s, External Memory and Storage for Computers, Mobile Devices, MUF-512DA4/AM, Gray, 2024

Great 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.

While more affordable Type-C flash drives are readily available on the market, I chose Samsung based on years of brand experience and a proven track record of reliability. This decision is particularly important given my specific use case — storing footage from a dashcam or in-vehicle security camera that operates in a parked car exposed to direct sunlight daily. Under these conditions, the drive is subjected to extreme heat on a regular basis, which can significantly shorten the lifespan of lesser-quality storage devices. What makes this choice critical is the nature of in-vehicle security cameras — they typically provide no alert or notification when a flash drive fails or becomes corrupted. You simply would not know it stopped recording until the moment you need the footage most. In high-stakes situations like these, reliability is non-negotiable, and Samsung has consistently delivered on that front over the years to me. The compact form factor is another notable advantage, as it fits discreetly and seamlessly within the interior cabin of my vehicle without drawing attention or obstructing anything. As for storage capacity, 256GB is more than sufficient for continuous recording needs. To put it in perspective, 64GB is typically the standard entry-level option, while 128GB serves as a common upgrade — making 256GB a future-proof choice for those who prioritize uninterrupted, long-term recording without frequent data management.

This flash drive is beyond incredible. After going through 6 cheaper USB Flashdruves on Amazon with great size GB’s and really good reviews. Had over 50,000 pics and videos that I wanted to back up from my iCloud. They all started great and were impressive only to about a 1/4 in they would either stop writing or give me an error message. 2 of them even showed them being transferred only to find out hours earlier that they didn’t transfer . The cheaper ones also took such a long time to transfer files even though I legan to transfer a small batch at a time . I finally gave up and decided to pay a higher price for this Samsung drive. My goodness. This drive is incredible. So fast at transferring and it allowed me to do bigger size batches . I transferred all my 50-60,000 pics and videos probably within 1-2 hours. I kept checking on them as it was going so fast that I thought something wasn’t right but, all the pictures and videos were transferred correctly with plenty of space left. I wasted over a week and a half of over 8-10 hours a day with those other lower priced usb drives and with this one, o accomplished everything in 1-2 hours. It’s mi d blowing how awesome this drive is . I recommend it without a doubt . Spend a little more on this and save yourself the wasted time and frustration that those other lower priced ones cause

Very fast delivery. Good packaging and safely delivered. Small device and works perfectly with my Samsung phone.

no good
