Question about Samsung 870 QVO

According to the Acer website, the Acer Nitro 50 - N50-610 is a desktop computer with two M.2 slots. If you have never upgraded the PC before, only one of these two M.2 slots should be occupied by an SSD. This means that you can install another M.2 SSD. (However, I do not know which type of M.2 SSD will fit, as there are also differences here).

SSDs with an M.2 interface are much faster than SSDs with a SATA III interface (like the Samsung 870 QVO is). I therefore recommend buying an M.2 SSD instead of the 870 QVO, unless you absolutely need 8 TB of storage space or want to be able to take the SSD with you, as M.2SSDs are only available at reasonable prices for private customers up to 4 TB and are usually permanently installed in the PC (however, there are also external housings for them, in which case they can no longer fully utilise their speed advantage over SATA III SSDs).

Two more notes on the service life and speed of the Samsung 870 QVO:

This SSD uses QLC NAND cells (Quad Level Cells), i.e. 4 bits are stored per cell. This means that it is slower than SSDs with TLC NAND cells (Triple Level Cells: 3 bits per cell), MLC NAND cells (Multi Level Cells: 2 bits per cell) and SLC NAND cells (Single Level Cells: 1 bit per cell). However, it is cheaper. However, their average service life is also shorter, as each NAND memory location only allows a certain number of write cycles and, due to the storage of 4 bits per cell, each cell is naturally subjected to more stress than with TLC, MLC or SLC SSDs.

The Samsung 870 QVO with 8 TB has a so-called SLC cache of "only" 78 GB. When data is written to the SSD, this cache is filled first. This happens very quickly because it consists of SLC NAND cells (see above). If the SSD has nothing else to do, the data is then copied to the slower QLC NAND cells in the background, freeing up the fast SLC cache. Thanks to this SLC cache, the write speed is fast (max. 530 MB/s, the SATA III connection is the bottleneck here). But if you write more than 78 GB at a time to the SSD, the write speed drops drastically (to only approx. 160 MB/s). SLC caches and DRAM caches are frequently used in SSDs. The QVO 870 is therefore not an outlier in this respect. The only special feature here is that the SSD is relatively large, but its SLC cache is relatively small in comparison.
