Samsung 840 EVO SSD
SanDisk was the first company to use MLC NAND as emulated SLC for very fast programming. Toshiba is doing something similar with its two bit per cell MLC. However, tiffany Samsung tiffany arguably gets the most mileage from this technique because it’s using TLC NAND. Though each technology works a little differently, the idea is that, by setting aside some amount of memory to operate in SLC mode, performance improves substantially. As an added bonus, there are scenarios where this sort of caching can improve a drive’s overall endurance. Samsung’s approach does confer rigteous write numbers, even if that’s only until the cache fills up.
Based on the table above my chart, the 120 GB 84 tiffany 0 EVO has about 3 GB of usable cache. That means it only takes about nine seconds to fill at 330 MB/s. Samsung says it’ll do more than 400 MB/s w tiffany ith Turbo Write, though. Obviously, as the cache fills up, speed is dropping precipitously. In this case, it dips as low as 169 MB/s at the end of one minute. This works so well in the real world because you’re probably not going to be writing for that long. Desktop usage patterns really lend themselves to this type of acceleration.
