SSDs are excellent for long-term storage, though that depends on what you consider long term. Theoretically, the NAND memory cells, which are voltage traps, could leak over time and become unreadable, but in the decade or so that SSDs have been in heavy use, we've not seen this type of degradation. Short answer, a couple of decades, yes; a couple of millennia, perhaps not.
The benchmarks don't lie! These are the best PCIe 4.0 SSDs… Note that in normal use, as a drive fills up, performance may decrease due to less NAND for secondary caching, as well as other factors. This issue has abated somewhat with the current crop of SSDs utilizing more mature controllers and far faster, late-generation NAND.
… PCIe 5.0 is even faster -- up to 15GBps with storage. NVMe: Non-Volatile Memory Express technology takes advantage of PCIe’s bountiful bandwidth and the unique properties of NAND such as multiple lanes and caching to create blisteringly fast SSD performance. …
… Note that in normal use, as a drive fills up, performance may decrease due to less NAND for secondary caching, as well as other factors. This can be less of a factor with the current crop of SSDs with far faster late-generation NAND. …
… Rather than upgrade your internal storage -- add a speedy external SSD. Not only will you have a lot more fast storage for your games, you can use it on any system you wish. …
… Note that due to the current global NAND storage the first of one of the many "benefits" of AI , SSD prices have skyrocketed, which renders some of the prices mentioned below and in the referenced review articles out of date. …
… It’s performance lends much credence to the theory that thermal design is important when it comes to high-speed external storage, or for that matter — high-speed storage in general. …
