First impressions very positive. In USB 3.0 that I tested so far, it has satisfactory speeds. TL;DR

In benchmark we have ~ 200/130 read/write MB/sec in NTFS (150 write in one test in exFAT format)

In file transfer ~ 11 GB we have:

Average read speed = 150 Mb/sec
Average write speed = 105 Mb/sec

So it may heat up after a while and temporarily decrease performance.

In terms of features, it is a bit large but OK.

It has a blue light that is not bothersome for indicating operation.

When opened, it gives a very nice feeling (I hope the mechanism will hold up)

Finally, in terms of quality, it is plastic so it will show over time.

Overall, quite satisfied, we'll see how reliable it will be over time. I am curious to try the pro model as well.

Very good USB stick, one of the fastest I have tried for file transfer, although personally I bought it to have music in the car. Just keep in mind that if you want to connect it to the car's source, you will first need to convert it to FAT32 from a computer, as most car sources only read FAT32 files. First try it out and if you see that the source gives you an error and doesn't read it, then convert it to FAT32. Also, if you have anything on it that you don't want to lose, make sure to back it up because formatting is done on the USB stick during the conversion to FAT32.

With one month of use, my experience with this specific USB is very good.
P.S.: I have another Sandisk 32GB USB 3.0, an old one, and it hasn't had any issues for 6 years, that's why I bought Sandisk again!

Well, the stick is awesome, simply fast and efficient. For DJ use, it needs to be formatted in FAT32 for Pioneer products.

I bought it mainly for my car to fill it with music, but the problem is that it doesn't read certain music files for some reason that I don't know and I have to convert them, they said. However, when I have 5,000 songs, I won't sit down to do it. So I wasn't very pleased with the purchase because I have it and it sits there

In linux RHEL 7, exfat, copying a 25 GB file from an SSD disk to a t480 laptop, the write speed is 160 MB/sec. The nmon showed a peak of 300+. For 20 euros, it's perfect.

I am very satisfied! In port 3.1, transfers have a write speed of 140mb/s and a read speed of 190mb/s. Now, durability will show over time! Anyway, at the price of 20 euros that I bought it for, in the 64gb capacity, it is a very good price, I believe.

It is a sturdy construction. It was tested for data transfer from a USB 3 port and the speed on a file of size 1.74GB was 138MB/s. It is worth buying and its price is reasonable.

It is clearly faster than the Ultra Flair, which is the tiny and at the same time Good Value of Sandisk, but also noticeably more expensive and much bulkier. If you are not interested at all in reading speed (and less in writing), go for the Ultra Flair and with the same money you get double the capacity. If you want speeds that really remind you of USB 3.0, and the large size does not bother you, prefer this one.

I have 2 of the 32gb ones and recently bought one of the 64gb ones for 17€. Excellent in terms of speed, I don't like their size and the blue power light on one of the three because it only shows in the dark.

Wonderfully fast product! I manage to reach speeds of 140mb/s in transferring individual files, of course in a USB 3.0 port. I recommend it to everyone I know with my eyes closed! The best value for money flash drive product I have seen so far!

Καλή απόδοση (μπορείς π.χ. να τρέξεις VM από αυτό), αλλά όχι στα επίπεδα του παλιού SanDisk Extreme USB 3.0. Σχετικά καλή ποιότητα κατασκευής, αλλά θα προτιμούσα να είναι πιο στιβαρό.
Συνοπτικά, προσφέρει καλή απόδοση και για 60€ πιστεύω πως είναι καλό value for money. Προσωπικά, είμαι πολύ ευχαριστημένος.

The fastest USB stick on the market after the Sandisk Extreme Pro :P
I have it since it came out and I am 110% satisfied with the speeds! Format in less than 15 minutes!!

Update 2019.
With the 960 Evo Pro (m.2), formatting literally takes 90 seconds (1 and a half minutes) EXACTLY! GOODBYE!
