Guys, I'm thinking about installing a new NVMe SSD on my computer. Is PCIe 4.0 or 5.0 more reasonable? Is cooling important, or is it standard in every model? Also, up to what capacity should I go for? What software aspects should I check? What do you recommend?
What should I look for when buying an NVMe SSD?

Here’s the translation:
You can compare PCIe 4.0 and 5.0 like this: PCIe 4.0 is already fast enough for most gamers and regular users—you barely notice the difference in most games anyway. PCIe 5.0, on the other hand, is more future-proof, expensive, and only offers advantages in rare applications right now. If you're constantly gaming or editing videos, a PCIe 4.0 model (e.g., WD Black SN770 or Samsung 980 Pro) is the smarter choice—it balances performance and price well. As for cooling, standard heat spreaders are usually enough for PCIe 4.0 models, but for high-heat PCIe 5.0 drives, active cooling—like models with dedicated fans or metal heat spreaders—makes sense.
For capacity, starting at 1TB and scaling up based on your needs is best—games and applications can eat up space quickly. On the software side, each brand offers its own tools to monitor SSD health and status (e.g., Samsung Magician, WD Dashboard), so it’s worth using them to keep an eye on drive health. If you already have a motherboard that supports PCIe 3.0 or 4.0, jumping to 5.0 is an unnecessary expense since you won’t be able to reach full speed. Always keep these details in mind when evaluating price-to-performance ratios.
