Transcend16GB JetFlash 790 USB 3.1 Flash Drive (TS16GJF790K) Black

Transcend ESD310C 1TB SSDIt's only a couple of weeks old, but so far it's as good as any SSD/flash/thumb drive I've owned. Probably better than any.It's used for backup, a little drive that can easily be carried in a pocket. It replaces an old SP drive of the same capacity that has been failing and is now landfill.The first test of this new drive was to copy a single 350 GB encrypted file to it from another SSD. According to Windows, the copy speed was about 425 MB/s. Is that actual MB/s or really MiB/s? Only Microsoft knows for sure. Whatever, the drive sailed right through the copy without slowing down.That is unusual. Typically a new drive would transfer data at a lower speed, perhaps around 300 MB/s and still might get warm while receiving a file of that size. If so, it might reduce the transfer speed to avoid overheating.The rest of the backup process involves dozens of files, from 2 bytes to 28 GB. No problems.There is a discrepancy with the serial number. The box and the drive itself show the same 10-character string, but CrystalDiskInfo shows a 20-character string which includes most of the string shown on the drive and box.It is Chinese, but it's from Taiwan, the guys I trust.

Excellent performance specs with 90 MBS read and 45 MBS write in a well made package. The slider to extend the connector moves smoothly and locks securely. I also like the fact that this flash drive is made in Taiwan by a Taiwanese firm rather than China.The only issues I have are minor and are with the ad & packaging. The Amazon ad states "Hardware Interface USB 3.0". The product packaging includes states "USB 3.1 Gen 1 flash drive". USB 3.0 and USB 3.1 are essentially the same thing and have the exact same performance specs so other than being confusing to some not an issue - just a little sloppy. The info on the product on the back of the packaging was too small to read.

I bought the JetFlash 790 3.1 Gen 1 USB 256 GB version (225 GB usable). Blazing fast until you hit the temperature limit, then slows down. (But, I won't hit the limit again after the initial big load.) Great price, so I am happy.

I purchased this drive to store and play music in my new Mazda. My vehicle requires a thumb drive to be formatted in FAT32. Fair warning, Windows explorer will not format anything over 32GB in FAT32. I tried alternate methods using the cmd prompt, but was unsuccessful. I finally had one of my daughter's friends reformat it, and she was successful. I did contact the manufacturer, who would only confirm that "it could" be formatted in FAT32, but never answered my queries on methods.In the end, it is now working, and as I do not like MP3's, I am putting all of my favorite CD's, in wav format, on the drive for in car use. I bought the 1 TB drive, and so far have 76 albums loaded so far. Based on the space still available, I estimate I can store approximately 1750 albums total, in wav format. That is amazing.

very handy

This drive is spacious, cool and super fast. The attached figure shows the speed of this drive when connected via USB-C. USB-A speed is hindered by USB 3.2 (USB-A port) speed and runs about half. I not only have a 1 TB model, I have the 512 GB version as well and It's just as fast. Transcend has a huge winner on it's hand with this model. I guarantee that when I need another drive, I'm sticking with Transcend. Highly recommend this manufacturer and model

Exceptionally fast speed, much more than expected. This is very very good. This is now my go-to USB stick with speeds resembling directly connected SSD‘s.

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?
