Question about Mx500 - 495153

I looked again. The Acer also seems to have a small M.2 SSD. (The description says 1000 GB HDD and 128 GB SSD) This smaller disk cannot be replaced by this Crucial.
You would have to check how it is connected. It is a plug-in card.

Since the Acer was equipped with an HDD according to the description, this SSD must fit. HDDs have long used the SATA connection, just like this SSD. Also, 2.5 inch are installed as standard. In the meantime, there are also NVME connections in laptops. These are small plug-in cards. But this is not possible with an HDD, the laptop would then be equipped exclusively with an SSD.
So the Crucial fits and is a good choice! Advantage: it is insensitive to shocks. Unlike HDDs with rotating magnetic disks. And it is much faster than the HDD.
