It is fully compatible with HDD 2.5, so it is suitable for PS4. Difference to 860? Well, everyone is moving with the times and bringing out new models. It's a little faster and even a little cheaper. :-)
The Samsung 870 QVO SSD is a 2.5-inch model that has a SATA III interface. However, the Icy Box IB-3805-C31 enclosure is designed for 3.5-inch hard drives. Therefore, it is not possible to install the Samsung 870 QVO SSD directly into this enclosure as it is not the right size. You need an enclosure that is specially designed for 2.5-inch SSDs.
I use the SSD in a UGreen enclosure that was recommended for it (USB 3.2) and switch between iMac and MBP, works wonderfully.

I have a DiskStation DS620slim (6 x 2.5") and can recommend: https://www.synology.com/de-de/products/DS620slim
Has power and speed, is quiet and economical. Disadvantage: it's not cheap.

Hello,
thank you very much for your enquiry. For the Samsung SSD 870 QVO SATA III 2.5 inch, your device requires a SATA 6 Gb/s interface, although the SSD is also compatible with a SATA 3 Gb/s & SATA 1.5 Gb/s interface, as well as a free mounting bay in the 2.5 inch form factor. If in doubt, please check with the device manufacturer.
Kind regards from Schwalbach

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.
