hello good people !
im gona pick this nvme for gaming Samsung SSD 990 EVO Plus 2TB NVMe M.2
then i want another storage for the windows system 500gb
should i get another nvme or normal ssd i feel like another nvme will put more heat out
the motherbred that i will get is Asus ROG STRIX B650-A GAMING WiFi
Just use that drive for Windows, otherwise you're going to be putting Windows on the secondary drive so you can have the 990 EVO on the primary slot, and depending on the drive and your CPU, that could slow it down a good bit. Unless your gaming earns you money and a half-percent performance difference that you might not see depending on your usage makes a difference, paying an entire separate SSD for it is ridiculous.
For mass storage, SATA works fine, but if there's a lot of back and forth of large amounts of data then NVMe will feel a lot better because you won't be waiting for such transfers to finish. An inexpensive DRAM-less PCIe4 drive is fine for both OS/apps and storage, and won't put out a lot of heat except during the longest data transfers, but that's not a huge amount compared to the rest of the system. Stick a heatsink on it and the case airflow should move the heat away from everything else and reduce any possible throttling of the drive. It's not going to make your GPU or CPU breach any sort of threshold even directly under it (if it does, those were already on the brink anyway and normal environmental variations could do the same).
If you're really just going to use the second drive for the OS and basic apps, then a 2.5 inch SATA drive will work fine generally, but noticeably slower than NVMe. It will take several more seconds to boot, apps will start up either just as fast or much more slowly depending on how much they have to load from disk, and you absolutely want to ensure you keep at least 25%, even 50% of it empty to ensure the caching algorithms have space to work with. Just make sure it's a good, well-reviewed drive in that capacity. However that's going to cost pretty much the same as an NVMe drive of the same size, and heat shouldn't really be a concern with the NVMe drive so I wouldn't even take that into consideration.
