The Crucial P5 Plus did impress us quite a bit in terms of performance and we were quite surprised that the controller remained at acceptable temperature levels even when writing continuously to the drive. You will have to expect the usual performance fluctuation when SLC gets filled up but in most usage scenario there won’t be any issues even when downloading very large games off Steam. Our tests were conducted inside a well-ventilated computer case but expect the situation to change if your enclosure does not feature active cooling or is installed inside a laptop.
