My 2TB AGI NVMe SSD has been causing serious problems for several days. During large downloads or installations, it often reaches 100% active time, response times become extremely high, downloads drop to zero, and the entire PC can feel unusable even though the rest of the system is fairly powerful: an Intel i7-14700F, RTX 5070 Ti 16GB, 32GB of DDR5, and a Gigabyte B760M C V3 motherboard.
I mainly use the computer for gaming, large Steam and Game Pass downloads, mods, Windows, and everyday tasks. I suspect the AGI drive may be defective or simply unable to handle sustained writes properly. I'm considering a 2TB Samsung 990 Pro, possibly the heatsink model, but I'm not sure whether its premium price is justified.
My target budget is around $150–$250 for a 2TB PCIe 4.0 M.2 NVMe SSD, although I could spend more if there is a meaningful reliability or performance advantage. Reliability, a good warranty, and consistent performance during downloads and installations matter more to me than benchmark numbers. I'm also open to using the motherboard's heatsink instead of buying a drive with one.
Would the 990 Pro be a sensible choice for this system, or would a less expensive 2TB TLC NVMe from a reputable manufacturer perform essentially the same in gaming and everyday use?

I would not move games and large installs to a hard drive just to save money. A SATA SSD would be preferable to an HDD if you needed a cheaper secondary drive, but a modern 2TB NVMe is the better fit for this system. Before replacing the drive, check its health, temperature, firmware, and whether the issue follows the drive to another slot or system.
The 990 Pro is excellent, but it’s probably more than you need for gaming. A reputable PCIe 4.0 drive from Kioxia, SK hynix, Crucial, Micron, Kingston, ADATA, XPG, PNY, Lexar, or Seagate should feel virtually identical in games and normal desktop use. I’d focus on the specific model rather than buying the cheapest drive blindly, and avoid obscure brands with questionable support.
The 990 Pro is a solid, reliable option if the price is competitive, and there’s nothing wrong with choosing it. I just wouldn’t pay a large premium for it because gaming load times and everyday responsiveness are usually very similar on good midrange PCIe 4.0 drives. Put the savings toward a higher-capacity model or keep it as a backup fund.
Older pricing made the 990 Pro easier to recommend, but current prices can make other established brands much better value. Compare warranty, NAND type, endurance, and reviews for the exact model.
The biggest improvement may come from replacing the problematic AGI drive, not necessarily from buying a flagship model. Look for a 2TB PCIe 4.0 TLC SSD with a DRAM cache or strong controller, a five-year warranty, and a reasonable endurance rating. The motherboard heatsink should be enough as long as it makes good contact and has proper airflow.
For sustained installs, I’d also check that the drive uses TLC NAND rather than QLC. TLC generally maintains write performance better once the cache fills.
