So you’re saying the SSDs tend to experience issues being used as the boot drives? If so, why is it that many people consider them being more reliable than HDDs? Doesn’t the fact that they contain no moving parts make them more reliable?

As for running the OS on the RAM, since the data is only unloaded to secondary storage during a shut down, doesn’t that mean a sudden power off would lead to data loss? Since the pc didn’t get the time nor did it know that it had to unload the data.

It is well know that SSD are not reliable as HDD when talking about data storing. We use SSD as boot devices because THEY ARE FAST thanks to their flash-nand technologies. HDD can't compete because they use a technology based on cylinders and sectors that are read by a mechanical arm.

Every SSD sold comes with an assurance of I/O operations called TBW: for example my KINGSTON A400 120GB SSD has an assurance of 40TB of writable data!
That's a lot but when you exceeds that number you can except problems comings soon.

A 480GB SSD has a 160TB assurance!

Regarding running OS from RAM... you are right, when the OS preload ALL the data on RAM and then an unexcepted shutdown happens all the data will be lost. But you can also configure your distro you preload on RAM only system & applications file meanwhile your data partition is simply mounted and accessible from your USB.
