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 I'm getting ridiculously slow write speeds of 150KB/s! Kilobytes! Read speed continue at around 60-70MB/s, but I just can't get why the write speed is so abysmally, deficiently and spectacularly slow. Practically can't 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.

Not the fastest drive in the world, but for the price its pretty good. Exterior construction seems maybe a little flimsy, so its probably not the best drive to have hanging from your keys at all times, but I'm sure it would be fine in a laptop bag or something like that (what I'm doing with this drive) it would be fine.

Does exactly what it is suppose to do. Works well. I like the light that indicates it is fully engaged in the socket. The light also blinks to indicate when data transfer is taking place.

I ended up buying two of these--the black 32 gig USB 3.0 version first. I had initially ordered another Transcend USB drive along with it but the write speed was half what this one is so I returned it and ordered this one again in white. So far so good with read/write speeds. They are as advertised which when I compared them to other drives in this price range is pretty good. 32 gigs for under 12 bucks was unheard of just a year ago. I like the fact that the USB connector draws back inside the plastic housing so its protected. When you need to connect it, its locked into place so you dont have to hold the button down to make the connection. The light is a nice touch. Yes, you can live without it, but having an indicator to let you know if the drive is busy can save you from pulling out the drive at the wrong time thus corrupting the data. Transcend memory cards have been very good to me in the past. Its all I'll use in my high end digital camera. Here's hoping these USB drives also continue to impress me with their performance and longevity.

Pretty fast, but a good example of why benchmarking software isn't much of a guide. Here's 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 used this flash drive on both my 2010 and 2014 Macbook Pros. It was plugged into a 2.0 USB Hub and a 3.0 USB Hub without any issues. Recommended.

This is an excellent flash drive. It seems very well made and does hold a lot of information. I have all of the Game of Thrones discs for all 5 seasons, and I was able to fit all the episodes on this flash drive. This makes it so much easier instead of always having too change discs when I'm binge watching. I just plug it into my tv and go. And for the large amount of videos I put on the drive, it transferred the videos very quickly compared to some other flash drives I have. I definitely will be purchasing more of these.

This isn't the best flash drive out there in terms of speed, but with that in mind it is quite fast and it is probably the best flash drive out there on this price.
