Transcend 32GB JetFlash 790 USB 3.1 Flash Drive (TS32GJF790K),Black

Great drive with speed of about 10 MB/s on a 2.0 port. This drive does not run hot. Great price too.. Right now the 32GB black costs about $13 and the white is about $10. Also bought a white one, and its 2.0 write speed is also very good. Large files transfer at about 10MB/s. Batches of smaller files naturally get written at about 8MB/s. Light behind the blue slide is very visible, and is always on. With the white case, blue glow fills the bottom of the drive. I bought another black drive. It is different: doesnt say USB 3.1 on the case and there is no light. Performance is the same I guess. I have many drives, so I like to buy different designs from many highly rated manufacturers so all my drives look different. Drives from this brand have never failed me. -Chris

When I initially got this drive to test it I was skeptical about its quality. Not only is build quality great, but so is the drive. Its about average for USB 3 drives speed wise and it has a good Silicon Motion controller in it. Not the PHISON crap some other cheap manufactures use. Would recommend, especially for the price.

This is a fantastic USB 3.1 flash drive, especially for the low up-front cost. I was able to create a Windows 10 boot disk from my MacBook Pro (Mid-2015) using Terminal in less than five minutes with this drive. In turn, I was able to perform a fresh Windows 10 install on my girlfriend’s Yoga 910 (with a new WD BLACK NVME SSD) in under ten minutes. If you need a low cost USB flash drive to successfully execute quick capabilities and tasks while not caring about looks, this USB flash drive is the product you’re looking for.

While doing an rsync with -v --progress, you will notice something. At first, these pretty much say, gimme, gimmie, gimme! Oh, heck...itll peak at over 100 megabytes per second, definitely USB 3 speeds. Then after a couple hundred megabytes, the transfer rate starts dropping. Then it will level off at a few megabytes per second. My testing indicates the best speed you will get is in the high twenties of megabytes per second, or pretty much USB 2 speeds. This doesnt seem to be a limitation of my system, because even spinning rust drives can sustain a minimum of 60 MB/s, and more usually around 80. So these have an adequate amount of capacity for the price, can read reasonably fast (over 100 MB/s), and can write fast in short bursts. But dont count on it for sustained high def video capture for example. Its much more suited for something like overnight backups. The case design is fairly good, no USB port cap, but instead a sliding design. But like a lot of others, its too easy to press on the retraction slider while inserting it into a USB port, so you just have to be careful how you grip it. Otherwise, the keep it open latch is adequate when the slider is not pressed. I would be willing to pay a little extra for a very visible status LED (on while plugged in, quickly flashing when reading or writing). But thats my bad for not looking for that in the description/specs.

Im giving this the 5 stars it hugely deserves for price and capacity. Im expecting longevity as well, since so far everything Ive purchased from Transcend has been problem-free. If it doesnt last, Ill come back and grumpily remove some stars. Im 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 youll be waiting longer than you are used to these days. I didnt 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. Dont fool around with the all-important aspects of learning smooth connection and disconnection practices with this. Take care, dont yank and pull but go slow. Youll 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. Im 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 Im 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?

No surprises here. Works as advertised. However, the transfer speed is something of a question given it is a USB3 drive. But no complains at this cost.

I wanted a reliable and USB 3.0 speed flash drive at around this price (64G@$25). The reliability remains to be seen, but I have had the Transcend 16GB USB3.0 for over a year and its good and this drive has a lifetime warranty. The problem with it so far is that it is advertised as 28MB/s write speed. I loaded 13.4 GB of data and it started out at 25MB/s for about the first GB but slowed to around 11MB/s for most of the write. It took about 20 mins and the average speed was 11MB/s. This is a USB3.0 speed but not as fast as I hoped. Maybe more expensive flash drives perform better, but I dont know and am not spending more money on expensive ones just to find out. For overall value of price/capacity/performance/reliability, this is a good drive.

The sustained read speeds of ~90MB/sec are not shabby at all but the sustained write speed of 70MB/sec really blew me away.

I just got a car with a USB drive reader and went into Windows Media and transferred all my favorite music to this stick. I still have a bunch of music in my iTunes, which I cant wait to get transferred over to this. The transfer is so fast that sometimes I didnt believe it had actually happened. I am able to select music by artist, album, playlist or shuffle. I am enjoying this so much. I just got home from a week that put almost 1000 miles on my car, and about half the time I was listening to my tunes, a lot of which Id never even heard. I cant believe how much room I have to spare on the stick.

I needed a drive with a lot of data for GIS that wasnt too expensive, and this is almost perfect. If I could give 4.5 I would. Pros: -inexpensive -fast -slider easy to slide back and forth -has a light to show its active -has key ring opening Cons: -drive opening not covered -slider does not click when you slide it out, so sometimes it wants to slide back closed
