Review on Sleek and Powerful: Samsung 860 EVO 500GB SSD - Boost Your Device's Performance! by Adam Kowalski ᠌

On the used disk, the steady speed of writing large files is about 60 Mb / s. I decided not to measure the disk speed with special software sponsored by disk manufacturers, but made my own software, since modern programming languages ​​allow you to make such software in a couple of hours. If you are a programmer, you can make similar software yourself and compare the results. The algorithm is simple - first, the entire disk is clogged with files whose size is randomly selected from the options 4kb, 8kb, 16kb, 32kb, 64kb, 128kb, 256kb, 512kb. Then a randomly selected 25% of the files are deleted. This is a simulation of light disk usage. Large files are continuously being written to the freed space. When there is 10% free space, the speed is measured. For this disk, the resulting figure is 60 megabytes per second. This is the speed that should be expected in the future. I can't say that the speed is low, because the main operations with the disk take place not in large files, but in blocks of about 100kb, and when working with such blocks, this disk is on average 10 times faster than a conventional HDD. I can’t say that the speed is low also because the other SSD I tested was 4 times slower. But I would rely on the advertised 500 + Mb / s only when it comes to reading operations. I think that you can take a disk for most household tasks, but I don’t see any reason to jump for joy.
