First of all, the complaining about the poor performance of the sticks: Take time AS-SSD and measures the sequential values of the sticks to (the supreme test in AS-SSD). You'll notice that the manufacturer does not lie in the sequential rate. The 32GB version reached me write 29MB / s and read 67MB / s, which is very close to the manufacturer's instructions That flash memory can cave in thousands of small files, is generally known. With USB sticks this is due to less severe Controller even more pronounced than in SSDs - but even the best SSDs break strongly in small files in the speeds a. HDDs do this by the way too! Sequential read and write values are therefore always measured with large files. If you want to copy large amounts of files on a flash drive smallest, it is always worth it, this pack in an archive in advance, so you can copy a large file.
The JetFlash 700 is in my opinion a very good stick, because it makes a good performance at a good price. There are faster USB 3.0 drives, but prices are rising in these quickly in ridiculous areas for which one gets a good SSD plus external housing - and that would be a better solution when it comes to a high absolute performance.
The JetFlash 700 has in any case a good size for your pocket, the design is simple and good, and the cap is firmly attached to the connector. That should, in principle, from any USB stick can expect that but unfortunately not all manufacturers provide.
