I'm curious about the key differences between premium SSDs and more budget-friendly options. For example, what do I give up if I go for a 2TB Lexar NQ780 M.2 instead of a 2TB WD Black SN850X? Are there specific features or performance aspects that are significantly different?

When it comes to budget vs premium SSDs, reliability and quality assurance are also key factors. Premium drives often undergo stricter quality control, giving you more peace of mind down the line.
One of the main things to consider is sustained speed. Budget NVMe drives often come with older controllers, lack DRAM, or use cheaper chips that have lower endurance. If you’re mainly gaming, you might not notice much of a difference. However, if you’re handling large files or doing heavy I/O tasks, a premium drive could be worth it. Also, definitely check out reviews and comparisons! For most people, something like the Lexar NM790 was previously well-rated, but prices can vary and stock might be limited.
Budget SSDs usually utilize QLC cells, which have lower endurance compared to the TLC cells found in premium drives. For example, a 4TB M.2 SSD with QLC might have around 800 TBW (terabytes written), while premium options can go as high as 2400 TBW. Premium models will likely include dedicated DRAM, which improves performance, especially in random 4K speeds, though this is becoming less crucial. Speed is important, but a horrible random speed is more of a concern than just overall speed.
