Here is the deal with reliability. The big names in the industry do no cut corners. Samsung, Intel, Micron/Crucial, SK Hynix, Toshiba and SanDisk are the fab companies. They make the flash and they also get first pick when from the production. These companies also know about features in the memory to enable or disable to increase reliability, performance and so on. Most of the extra switches have to do with the ECC (linked to reliability).
I kill SSDs all of the time. It happens so often that I don't even think about it when it happens. Many of the companies send me early drives to test with pre-release firmware. I would estimate that 2 our of every 5 die during testing. Retail products have a much higher success rate. I may kill one in every 60 or so. My testing goes well beyond what anyone would consider normal use so don't let the high percentage take away from buying a new SSD.
When a product review goes live that isn't the end of my testing. At any time I'm developing 3 to 5 new tests for consideration in SSD or NAS reviews. Every once in awhile you will see one of these tests in a regular review to show a corner case problem.
With that said, it's rare for a fab company SSD to fail. I'm not saying they never fail, just the rate is much lower than products from smaller companies. I have around 300 SSDs (maybe more) dating back to 2007 so we are not talking about a small sample size.
Last but not least, I've been in 4 test labs. Two of the companies were fab companies and two were not. The difference is night and day between what the big names in the industry do compared to what the smaller companies do.
That is not to say that I would never use SSDs from smaller companies. I do use them in my lab but when it comes to systems I keep valuable data on, I use fab company drives.
