I have heard that SSDs have shorter lifetime, than normal HDDs. And last time I have a suspicion, my SSD came to it's end. Symptoms include unexplainable BSODs, and program disappearing.
How could I ensure, that SSD is ok or not?
SMART gives no any signs:

That SSD has an endurance rating of 80 TB of writes and you have almost 73. It is definitely reaching then end of its rated lifespan.
Even with TRIM, that is a large amount of writing especially since the drive has a 10 year warranty (Meaning they don't expect you to write that much within that timeframe).
To answer the question about SSDs with higher endurance, there are more "write-oriented" drives and improvements to flash technology is constantly improving lifespans. However, it seems the issue here is an over-use of the SSD. Typically people put the OS and a select few programs with long loading times on the SSD, and everything else on slower mechanical disks. This lessens the amount of writing it has to do.
As a comparison, my SSD has a power on hour count on 5204 (I've had it in use almost every day for almost year) but only 5 TB of writes (Most were before I redirected my AppData folder to my NAS homefolder).

This drive was a system drive in a home computer, only operating system was on it. Pagefile, internet cache and My Documents were on other drive. How could I reach such value? – Dims – 2016-11-28T05:33:56.180

How do you know that (80Tb)? – Dims – 2016-11-27T21:31:25.577

Endurance statistics pulled from a review on Anandtech. SanDisk doesn't post that information on their product page.

How full is this disk - if is too full, there is no enough space for relocating the blocks? Maybe you have to disable auto defrag in Windows - it is killing the disk unnecessarily . Also what is memory usage - if you are low on memory it pages to the disk more frequently. Figure out which are the most disk active apps (writing mostly). – jet – 2016-11-27T22:35:14.273
Drive has approx 20 Gb free, page file is not located on it, and I have 32Gb of RAM – Dims – 2016-11-28T05:35:14.720
Wow, according to these values, I wrote at a speed of 7 gigabytes each hour!!! – Dims – 2016-11-28T05:36:53.283
