Hlygrail,
I will not talk from expertise, because I do not have any, other than my understanding of flash memory is that there are only so many read and writes that you can do to a bit of memory before you can do no more. Perhaps that has changed.
I also cannot comment beyond what was quoted about using consumer flash. I don’t know, and is worth a look.
However, what is clearly evident, is that PSTG’s products meet enterprise standard reliability, even for the most critical functions. There is no issue regarding PSTG’s products quality or reliability, and I fact, the company has the highest, by far, customer satisfaction rating in the industry, part of which is because PSTG uses the cloud to predict, before it happens, any storage failure, and is on the scene before hand to prevent it. 6 9s of reliability or such.
PSTG storage is used basically anywhere you can put an EMC or NTAP system without concern of reliability. No, PSTG does not have the product diversity of these larger companies, but in any area that these companies do compete against PSTG, the quality of the flash is not an issue in regard to reliability.
