I have had it here for two months. I use it as an external drive, having placed it in an external transcend case that connects to the mac mini via usb-c gen 1. I have stored various files on the drive, but at the same time, I have also installed some games on it (in order not to reduce the capacity of the mac mini's internal drive). Needless to say, the drive is fast, not just fast, but lightning fast even though it's not NVMe! I play the games that I have installed on it without it being noticeable that they are installed on an external hard drive. There is no delay in loading and no lag at all (of course, the games are not particularly demanding), as if I have installed them on the computer's internal memory. The main reason, of course, that I bought it was its price on the one hand (the cheapest 1TB SSD M.2) and the good reputation of crucial on the other hand. Its price compared to a classic 2.5-inch HDD is about 85 euros higher. I am fully satisfied with its price and its amazing speed. Of course, it is not an NVMe SSD, but for the work I need it for, it exceeded my expectations. I consider it to be the most value for money SSD, combined with the fact that it is a product of Crucial. Crucial has already upgraded its firmware twice (a very easy process through Windows, more complex on MacOS). I hope it also has durability over time.

UPDATE 5-3-2021: Two and a half years later, I confirm the good functioning of the drive. It has not disappointed me in the slightest and continues to work perfectly like the first day.
