The idea that SSDs are fragile snowflakes that will melt under the white heat of data is a bit of a mistake.
Many tests have been done where drives have been torture tested - tech report did one with last generation drives and basically its PRETTY hard to kill a modern SSD by excessive writes.
Bit of a disclaimer. SMART needs careful interpretation and will tell you something can go wrong. Not that it will. SSDs may have different smart attributes based on brand. Look up the documentation for your drive. I primarily own samsungs at the moment, so my answer references the drives I have and the software for them.
People have put SSDs through workloads significantly worse than what they have been rated for and they have survived. Treat them like any other storage. Back them up, of course, but they arn't typically going to die that fast.
There's a few factors to SSD endurance - process size (the larger the better but not always), bits per cell (slc is better than mlc is better than tlc) and so on. However most modern drive have impressive endurance,
However, most drives have a certain amount of 'spare' cells (aka overprovisioning) that should help mitigate dead/worn out nand. Amusingly, the best drives (enterprise class SLC) and worst consumer level TLC drives both have a lot of this. In short, the drive handles this so you don't have to.
Interestingly SSDs use the same SMART standards as any other drive, and either your manufacturers tools or your favourite SMART information tool will tell you the raw values. However the attributes may differ.
Annoyingly these standards are not too standard and interpretation is as much as art as a science. I just tend to rely on the little green health status label to tell me everything's fine. That said, samsung has a rough guide on interpreting the values and suggest except for total LBA's written, the raw values should be indicative of what's going on. Check your specific manufacturer to be sure,
Practically speaking, unless you're hitting the bathtub curve of premature death, or a wierd bug, your drive is at least going to live as long as the warranty.
