How often does flash memory fail?

I always thought flash memory was pretty reliable, but now I'm not too sure. I got a free 8 GB flash drive from Kingston for their 25th anniversary about a year ago. I didn't get to use it too much, maybe like 4 times. The next time I went to use it, it was already dead. Today I woke up to my SD card in my phone being shot. The phone was standing still charging all night, so I don't see anything that could have caused it. And it is the card. I tried a 1 GB card I had from forever ago. That one still works. But the one that broke was less than 2 years old and has never been taken out except once when I get a new phone. It's probably just bad luck, but I just want to check. And there aren't any tricks I can do to try to raise it from the dead are there?

One of my professors told me that newer flash memory is designed to last a shorter period of time to reduce cost.

You can't really "design" memory to last a year. Almost all computer parts are designed to last a long amount of time, usually 5-10 years. You can't really predict when it will fail, because it usually fails because of a defect, not because it hit it's end of life. I don't think I've ever used a computer part to where it actually reached it's maximum life expectancy, or anywhere close.

What you might be referring to is NAND memory, which is cheaper, but has good performance. People got all butthurt because the lifespan of the memory was much less than other types of memory, but honestly, I don't think I am going to keep an SSD for 5+ years, or any part in my computer.

I'm more referring to different kinds of NAND flash that store bits differently. Specific kinds that are used in Enterprise level drives last longer and have more writes than consumer level drives.
