These are my preferences. You don't have to agree with me.
Memory chips aren't used solely as SSDs. That also includes RAM and USB thumb drives.
And if you did read my 1st reply, i actually praised Kingston over their USB thumb drives and RAM. While Kingston SSDs are both good and bad (just read the reviews i linked).
Western Digital actually does manufacture their own flash memory. WD does it as a joint venture with Kioxia. And WD has been in business for a long time, specializing on storage media (mostly known by the HDDs they make). Heck, WD even bought Hitachi/HGST, where once 4 big HDD manufacturers (Seagate, Toshiba, WD, Hitachi) ended up as 3 big HDD manufacturers (Seagate, Toshiba, WD).
Big names in flash memory manufacture, starting from the highest market share, are: Samsung, Kioxia, Western Digital, SK Hynix, Micron. And then come other smaller ones.
Kingston makes flash memory thanks to their stake in Kioxia. And Patriot doesn't manufacture flash memory at all. Only thing that Patriot manufactures, are flash-based SSDs.

Everyone has problems. Nothing new there. And if you're not willing to pay premium for great performance, reliability and durability, no-one is forcing you to go with Samsung. There are plethora of "budget" options as well.
In the end of the day, read a reputable review to know how a specific product fares.
