Both of these are games, so they tend to sit with contents for longer. My boot SSD is 31TB in 6183 hours so quite a bit faster usage than those old drive but about half your rate. Its very workload dependent how long SSDs last. 16GB a month is extremely slow, much slower than my usage at 120GB a day. SSDs you could write their entire contents every day and they would still be working 5 years later but probably not 10.
