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

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.

I bought this Transcend Flash Drive on Amazon in 2015. I gave up on it for years, because I could not use it to store more than 32 GB of photo files. The label on it says 64 GB. I run Windows 10 Pro computers here. When I plug in the Flash Drive, select it in Windows File Explorer and right-click my mouse to see the drive properties, it says 32 GB. At the very least, this is misleading. At the very worst, it is false. The average user of a Flash drive should not have to resort to any formatting or change of file systems on the drive, in order to try and get 64 GB. It should perform as advertised, which I believe is a prime directive in product sales and advertising.

The actual write speed I got was 15 MB/s. I transfered small and large files. It works very well with a phone/tablet with android 5 by formatting the drive using the exFAT file system. With NTFS the drive was not recognized by android. It does not have a solid construction but if you are careful it will have a long life in your possession. The price is very good for the given capacity and it saved me some space on my laptop. I would buy it again. I will also try their encryption software one day.

I am a fan of Transcend brand USB Flash Drives. As a matter of fact, every flash drive that I own is Transcend. I have never had one fail on me yet and I use all of them all the time. I put music on them for the car and movies to watch. I format and reload. Never have an issue. I like that they are retractable so I can put them in my bag with my laptop and dont have to worry about them getting broken. Great brand; I am very satisfied and will be purchasing more.

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.

I purchased 2 of these flash drives and both perform ~ equal to USB 2 speed. USB 3.1 real world speed is rated at 3.2 Gb/sec and both drives perform at 0.2 Gb/sec. USB 2.0 real world speed actually a little faster at 0.32 Gb/sec. Frankly, I wont be buying any more of this product. Finally, the description claims that there is a LED activity indicator on each flash drive. I cannot see one anywhere on it. This is one of the reasons I chose this drive.

This is the second one for me. Hangs on my key chain and always available. Push out lock stops working after a while...I guess it wears out.

My computer shows a 117 GB capacity for this 128 GB storage device. Thats a big chunk to be doing without. The speed of writing was nothing like what was described for a USB 3.0 device. Example: writing a 3.7 GB folder from my hard drive to the Transcend 128 GB JetFlash 790 (using one of my Dell desktops USB 3.0 ports). The speed wavered wildly. At 35% completion the slow transfer simply ground to a halt for 5 minutes showing a completion estimate of 45 minutes. Finally it started up again and finished at just shy of 11 minutes. I then deleted the folder and repeated the test, which took just over 4 minutes. I deleted the folder again and repeated the process on my HP Spectra x360 laptop. It took 5 minutes, 20 seconds with speeds wavering wildly from 0 bytes/s to 42 MB/s. The practical upshot of this is that I never know how long of a wait I am letting myself in for.

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.
