My clueless "IT innovation manager" got two relatively cheap TwinMOS HyperSSD H2 128GB Ultra. One is working more than one year now. The other one I tried to use to make an office colleague's PC faster. It kept freezing so I put in an MX100 128GB in his PC and that is working great. Used the "Hyper"SSD as a scratch drive. Didn't last one month and failed completely. Went to the shop where it was bought and got it replaced as it was still under warranty. Second unit was also crap and didn't last long after a single Windows installation on it. Now it's a useless paperweight.
The only SSD I had that suddenly stopped working was a Sandforce based Corsair F60. It would show the folders but if I tried to access them, it would lock up. Kept it connected to my PC one day for a few hours and its controller managed to recover the SSD to full working condition. By then, I had switched to an Intel SSD already so it's still in my collection, with the original data, unused.
These are the only SSD failures I've experienced. I prefer WD and Crucial is also a good brand. Haven't used Samsung that much. Crucial MX500 is supposed to have power loss protection so that would be a good option for desktops. NVMe, I would prefer to stay with P31, SN850 or Crucial P5. Any other brands, no matter how cheap, I don't want to use them for anything critical.
Another thing: if you have a QLC SSD, keep a backup! It's bound to fail much sooner than later.
