Before you judge it strictly, you must do it with all the criteria first of all the price close to 20€, the price as much as a USB stick. Speed according to its use, small files low speed, large files normal speed, of course much higher than a similar 7200rpm. Data security is a very critical criterion, the disk is not responsible for data loss in any case but the user who has not backed up to another storage medium, but in any case, like all devices, it is consumable. SSD technology has cost amortization, that's why such a low price is logical and it is natural for its capacity and reliability to increase. Whoever wants the best disk takes the Samsung Pro with a 10-year warranty, but still, it doesn't mean they don't want another medium for important files. As a system disk, it removes stress from the mechanical disk, resulting in lasting longer over time.
