I got it along with some other JetFlash because the JetFlash 770 32 GB USB 3.0 is the only flash drive of mine that has lasted over five years. From the benchmarks, it seems to be the same device in a different shell, so I will give it the same rating. On the other hand, many stores sell it as USB 3.1, which may not actually be true. Unfortunately, I did not keep the packaging, and there is nothing written on the device.

Just got it the day before yesterday, seems good so far.

Until today it held up, but then it broke down completely. It is no longer recognizable at all. Therefore, I changed my initial evaluation.

I have it for about 3 years and I use it almost daily. It is durable and fast both on usb2 and usb3.

A very good USB stick that won't disappoint. It's not fast enough for me because I use it on a USB 2. The reason I chose it is the reliability of the company, having several products from them, and the price in relation to the GB.

I have had it in my possession for over 3 and a half years.

When it comes to files, even though the transfer seemed fine, when I tried to open them on another computer, they were damaged. Until today, when I spent 4 hours trying to figure out why I couldn't install Windows on a computer, it has "betrayed" me so many times that I am disgusted.

This is not the first time I have been disappointed with a Transcend flash drive. Never again with this company.
I have used simple series from Adata, Patriot, Kingston. No problems, no corrupted files.

I don't know if I am just unlucky, but I wouldn't recommend them to anyone, they can't handle regular use.

It's not bad, quite the opposite. It just has its issues from time to time. It probably has some design flaw where there is a small buffer that constantly drops to 0 during transfer/write and then goes back up, resulting in slow performance when dealing with large files (movies over 10gb). In terms of speed on a USB 2.0 computer, it writes at 12-15mb and reads lightning fast anywhere, especially on the television. Honest and good construction.

Very fast USB stick, reached read 110.3 and write 57.21 on a USB 3 port and of course the positive is the lifetime warranty from Transcend!!!!

I have it for several years, 2-3 maybe even more, I don't remember exactly, but I am not satisfied because the usage I gave it was minimal, apart from 2-3 times while I had it, and there were periods where I didn't use it, maybe even 6 months, until it burned yesterday. I wouldn't buy it again

It broke and I got another one with a warranty.
It's positive that it has a cap.
The USB starts to shake after a while of use.

I have two high-quality durable LED flash drives with a transfer speed of approximately 110 mb/sec from the stick to the PC and 24 mb/sec from the PC to the stick, in USB ports with NTFS formatting

I bought the first one 2 years ago and overall I wasn't bothered by it.
6 months ago I bought 2 more and there I found out that although they are the same model,
they have a slight difference in speed compared to the first one (unfortunately slower) and they have also removed the blue LED indicator, so you can't see when it's in operation.
Some things, instead of improving, worsen in pursuit of profit.

A flash drive to do your job... don't expect anything special, it's not terribly fast even though it's usb3.0. After years of use, it has gotten stuck and doesn't allow me to change the file type from FAT32 to NTFS, but it definitely made its money worth.

Reliable & fast flash drive. Very frequent use for 2 years, no issues. The price is also good. Prefer it.

For the past 9 months that I have it, it hasn't presented the slightest problem! It is fast and has a very good blue LED

Very good, I bought it after researching the best on the market. It is USB 3.0 with quite good speeds, small and convenient but the cap needs attention not to get lost.

I have had it for almost 2 and a half years and I use it every day. It has never given me any problems, but mainly it is simple and user-friendly and very fast. Despite the usage, it remains very fast unlike other USBs I have tried. I think it is better than many more expensive USBs as it is quite cheap for its quality.
