Transcend 128GB Dual USB C Flash Drive, Photo Stick for iPhone/iPad/Mac, Windows/Android/Tablet/PC/Smart TV/Gaming Console, Up to 420MB/s, USB 3.2 Thumb Drive, Memory Stick with 2-in-1 Type C &Type A

I'm glad I pulled the trigger on this little 2TB Bad Boy. It's super-fast and just works. Depending on your use, you may get different results. First, don't pay any attention to the speed specs of any stick or SSD drives. They all base their exaggerated speed claims on best-case scenarios. That being said, I use mine for storage and playing movie files on my Samsung Smart TV as I no longer use disc drives. It plays a full 2-hour to 3-hour movie without getting very hot and without a hiccup. When transferring movie files to it, I regularly got 200 to 300 MB/s write transfer speed (my Samsung T-5 and T-7 SSD drives write at 30 to 35 GB/s). If I transferred 200 to 500 GB at a time, it would get very hot by the time it wrote 150 GB's or so. If I blew air on it while it was writing, it cooled down considerably. And after a hundred GB or so and hot temp, it would slow down to around 80MB/s speed for a while but pick back up in speed, especially if I blew air on it to cool it down. So, I would recommend transferring about 100GB at a time instead of half a TB at a time. But either way will work fine. Don't let the hot temp bother you. It's designed to operate at the extreme temp. My Patriot 500GB and 1-TB sticks gets super-hot as well and they have never failed me. So, this is not abnormal. I also love the USB "C" connection it has on one end. Now I can finally make use of my "C" connection on my laptop and keep the other 2 USB-3 ports open. I use this Transcend stick to play movie files and my Samsung 2TB T-7 as the backup SSD drive for my movie files. But the Samsung SSD movie file transfer speed is only about 35 GB/s while this Transcend stick writes movie files at 200 to 300GB/s. So, I'm definitely going to get another one of these Transcend 2TB sticks. The hot temps and occasional slow-downs are really not a big deal when you consider the small size, convenience and extreme speed of this stick. And the end caps fit on snug. No issue there. If you've been thinking about this little gem, just get it. You'll be glad and impressed.

I'm giving this the 5 stars it hugely deserves for price and capacity. I'm expecting longevity as well, since so far everything I've purchased from Transcend has been problem-free. If it doesn't last, I'll come back and grumpily remove some stars.I'm not using this for incessant daily transfers, but more as an exceedingly handy all-purpose storage bin. And it definitely requires 3.0 after it starts to fill up, or you'll be waiting longer than you are used to these days. I didn't love it laboring away on a 2.0 connection. But 3.0 is fine for my purposes.And I appreciate that it works without fuss with everything from an antique netbook to several laptops of various vintages and powers. When I do want to share something among my widely varied collection of this and that, it is a pleasure to have this wonderful capacity.Don't fool around with the all-important aspects of learning smooth connection and disconnection practices with this. Take care, don't yank and pull but go slow. You'll save yourself a lot of trouble by noticing precisely how this device wants to be connected and disconnected. (In the last 20 years, every USB device I ever bought was a little different than every other one--- and they all still work well. I'm certain it pays to be faintly obsessive about this part.)I keep all my uncapped USB drives in zipped cases to keep the dust out. Capped, uncapped, somewhat capped: it matters.Some years ago I accidentally sent a Transcend 64 GB flash drive through a washing machine cycle. Because it was securely capped it still works as well as before. So I'm just more careful where I take the slide-in varieties like this one.The real question is: how much in the way of educational material, cultural enjoyment, tech-tools and sheer fun would you like to carry around?

If you are connected through a USB 3.0 Hub and transferring large amounts of data, it can crash your system. I was transferring from my USB 3.0 HDD to the USB SSD, both are 2.0TB, when this kept happening. At first I thought it was a DELL laptop Or MS update, but it kept happening. Then I realized it might be the USB Hub, which is USB 3.0 compliant, causing a bottleneck. So, I swapped it with my USB HDD, which was connected to a port on my laptop. It copied a large amount of data without a crash. Then I copied smaller chunks of data, to be safe. It took most of the work day to do this, but the drive is working fine. I just wanted to put this out there for others who may experience the same issue and for people looking to buy this. Overall, I think the product will work well and there is a noticeable speed difference. I do a lot of math in my spreadsheets, which are also very large. So each spreadsheet ranges from 30MB to ~120MB. On a USB HDD, this is a very slow process. While I still have to wait on very large spreadsheets, the USB SSD is quicker, much in some cases, and therefore saves me some time. I have not tried transferring through the USB C connector yet. I am curious how well this will work for my phone.
