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

Needed a flash drive for my Yamaha DGX-670 keyboard and this was a great value for the money. Works just fine...recommend!

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.

It saved everything I needed and was speedy. I bought another brand at the same time and that one failed and had to be redone while this one was efficient and worked as needed. The only negative was plugging it in to tight spaces on different equipment made the head slide in. I dont like the way it slides in and out. Because of tight spaces and other cables, I couldnt have two fingers on it when plugging it in so it would slide and I couldnt put pressure on it to plug in. Others Ive used I can just push in from the back end but that makes this one close up. You have to hold the slider open on the sides. Its hard to describe, but it made some applications difficult. When I was just using it on the front of my PC, it performed very well. Just transferring the info to other equipment was difficult.

UPDATE: After many days of having issues, I tried to reformat a couple of times with the same results, but then I used the SD Card Association formatting tool, and after it properly partitioned the drive, I got acceptable write speeds (60MB/s average) all over again with any kind of files (a lot of small files, big files, ...). OLD: First days everything was fine, however now Im getting ridiculously slow write speeds of 150KB/s! Kilobytes! Read speed continue at around 60-70MB/s, but I just cant get why the write speed is so abysmally, deficiently and spectacularly slow. Practically cant write anything more, so, in practice it is now a read only drive. This is very weird, I usually like Transcend products a lot, particularly their SD cards and readers, but this situation makes me very sad. I have tried a couple of machine, different operating systems, USB 2.0 and 3.0 ports. Nothing, it just keeps at that speed. Meanwhile I can use a 64GB SD card with a Transcend reader, and get amazing read and write speeds, so this drive is the faulty link on this issue.

I bought this thinking it was just another jump drive. Turns out that USB 3 series can interfere with wireless keyboard IF plugged into desktop next to wireless keyboard/mouse widget. Basically the mouse wont work and keyboard is sporadic. Something about wireless interference. I bought a dongle to plug this into and then plugged the dongle into back of desktop away from wireless widget. That seemed to solve the problem.

nice product and came quickly, I like it, even though the insert key is quite hard to put in sometime cuz it kinda unstable abit but overall is okay for this purchase.

I like the flash drive since it has really quick transfer speeds. You dont need drivers it just works even on Linux which is my daily driver.

Pretty fast, but a good example of why benchmarking software isnt much of a guide. Heres what Crystal Disk Mark has to say (and the photo shows a transfer of two video files on Windows 10, with an SSD source and this drive plugged into a fast USB 3.0 port that lives up to the 3.0 standard): Sequential Read (Q= 32,T= 1) : 102.911 MB/s Sequential Write (Q= 32,T= 1) : 97.646 MB/s Random Read 4KiB (Q= 32,T= 1) : 6.301 MB/s [ 1538.3 IOPS] Random Write 4KiB (Q= 32,T= 1) : 0.262 MB/s [ 64.0 IOPS] Sequential Read (T= 1) : 105.711 MB/s Sequential Write (T= 1) : 87.028 MB/s Random Read 4KiB (Q= 1,T= 1) : 5.113 MB/s [ 1248.3 IOPS] Random Write 4KiB (Q= 1,T= 1) : 0.231 MB/s [ 56.4 IOPS] Please see the photo of an actual transfer- it slows to about 23MB/sec after 150MB are transferred.

This drive saved me.. We had a complete system crash but we had set up a back up set with Norton and used this drive. It put everything back where it belonged.....

I bought four of these Transcend 32 GB JetFlash 790 UB 3.1 flash drives to create bootable Windows 10 drives to install or upgrade computers to Windows 10. I had been using some old USB 2.0 flash drives. I use a program called Rufus to transfer the Windows 10 ISO to the flash drives. The first transfer I did seemed to go really fast so I decided to time them. I timed the transfer to the 2.0 drives and then to these 3.1 drives. The 2.0 drive took about 7 minutes and 30 seconds to transfer. The 3.1 drive that I timed with a stopwatch took about 3 minutes and 25 seconds which seemed slower than the first 3.1 drive I used. Theoretically, USB 3.1 should be about 20 times faster than 2.0 (3.0 is about ten times faster), so the transfer to the 3.1 drive seemed a lot slower than it should have been. Ill be setting up more drives when Win 10 build 2004 comes out, so Ill time the transfers again and see if it differs much. Overall, though, Im happy with these drives.
