As everyone knows, the problem of SSD is that a memory cell can not be rewritten any number of times. Without going into the technical, TLC memory is less expensive but also less endurance than MLC memory that powers the vast majority of SSD. The only user was previously Samsung, and voila joined by Sandisk. However, it is relative, after all testers, MLC or TLC, there is a good chance that the SSD is no longer used long before the memory loss is not felt. We're on the life time of more than 5 years, and it is already a small eternity in computer science (especially with the current obesity pictures (minimum 8Mpixels for photos of smartphone, 8GB for a movie in Full HD) . That leaves a 240 GB SSD that works very well. An SSD is to deprive one of the most important checks on a PC (or a Mac). It's give new life to an aging PC and unleashing the potential of a modern PC, depending of course on what you want to do, but even for a game, the contribution of the SSD can be significant. The most caricatural is the sims 3 with loading time is absolutely - ABSOLUTELY - extraordinary. With an SSD, it becomes feasible (it falls below 3-4 minutes charging). As I just bought another SSD (the crucial MX100), I could do some tests. 1) When I copy a large file from my HDD to my SSD, I get a rate of about 60 MB / s 2) when I copy to SSD SSD, I turn to 210 MB / s. It is far from 500 MB / s promised, and I do not know why. In theory, I should be at 3Gb / s, that is to say to 375 MB / s. What matters anyway, is that we will 4 times faster. 2a) focus, initially, I had put one of the drives on a PCI SATA III card 6Gbs, and there, I got a rate twice as low. I do not know why again, but this shows that it is better not to try too hard to optimize. 3) when I make copies of small files, the difference is less sensitive, since I only have a 2.5-fold acceleration (40 to 100 MB / s). Do not complain, it's not bad, and it is very sensitive in practice.
Anyway, there are a lot of tests on different sites that allow specialists to gain some pougnèmes microseconds. In practice, SSDs of this range is probably worth. They allow anyway to upgrade one of the best that we can imagine on a PC. Single point, be prepared to reinstall your PC. The solutions to clone your disk is not perfect, far from it. In the case of this SanDisk, anyway, none is provided.
