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

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.

For those of you who care about such things: the current version of the JetFlash 790 does *not* have an LED indicator, despite what the item description says. I have an older one of these that does have the indicator. Sustained writes on the one I just bought are around 20MB/s and reads are around 120MB/s.

Slider is too loose. It moves in and out on its own when in pocket.

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.

I picked this up to load isos and livecds to be my all-in-one boot device. I only picked this model because of price versus usb 2.0 drives but I am very disappointed in the 3.0 speeds. I wasnt expecting much coming from a sandisk xtreme doing insane write speeds but I was still sad to see usb 2.0 speeds. 11-15mbps write when it claims 45, Yeah right. Skip a few cups of starbucks coffee and get the sandisk. That being said, it works great otherwise. The kind of computers I pop this baby into doesnt have 3.0 ports only my home computer.

The size of 64 GB is good for collecting brief video records. But because the speed is not good enough, I am going to use this to store video clips and play on various PCs. If you want an USB stick of a large capacity and if youre going to write on it frequently, this one would be not so recommendable. Id like to recommend SANDISK Extreme USB 3.0 or SANDISK Extreme Pro USB 3.0 for frequent writing. They have decent speeds both in reading and writing. Ive been using various USB sticks over more than 15 years and found only SANDISK Extreme USB 3.0 / Extreme Pro USB 3.0 have suitable speed for their great capacity. This one would be recommended for temporary storage for a great volume of data with less frequent writings. SANDISK Extreme / Extreme Pro USB 3.0 are definitely the ones to go with if you can ignore additional cost. With this one, you can expect a great capacity but not a suitable speed to fill that capacity.

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.

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.

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.

This flash drive is great and for the price I paid for the capacity. I basically can carry around a few thousand songs and bunch of full HD movies in my pocket! Its amazing how much flash drives have advanced over the years. I used Black magic speed test to test the speeds. It clocked the read speed at around 120MB/s and the write at 80MB/s. To be honest it is pretty slower compared to my other drives but I will take that trade off because of the capacity.
