SLC drives have around 100,000 write cycles. Most consumer SSDs are QLC now and those have less than 1,000 write cycles. They also tend to write slower than a mechanical hard drive when the write cache gets full. Some of those drives can be modified to run in pseudo SLC mode. That trades capacity for speed and write endurance.
Just buy a small, industrial CT scanner and scan your device. Compare the results to a device that you know hasn’t been tampered with.
