I've had SSDs die on me; my first SSD was a Samsung 64GB SLC; that worked for about 2 days? Right after I installed everything I needed, it went and died on me.

I've tried a couple off-brands and those haven't all been flying colors either.
 
My Kingston SSD NOW V 300 120 Gb died on me too

A couple of days ago I bought an SSDNOW V300. Attached it externally to my MBP, I formatted alright and cloned the internal HD with SuperDuper. Suddenly the SDD died, and there is no way to see or mount it. Called Kingston and am waiting now for a replacement. I wonder how common this is. Is it safe to migrate from and old-and-trustworthy (until now ;-) FUJITSU MHW2120BH to a flashy Kingston SDD ?
 
Kingston SSD V300 240 GB

Yep. Same here. Bought a new SSD. Tried to clone from my HDD. Cloning procedure went flawlessly. But I could not boot from it no matter what. Spent the whole day installing and reinstalling drives... Finally inserted my SSD as the primary drive and made an internet recovery. Installed after waiting for about 12 hours (slow internet connection). Worked like a charm at first. Then it froze. Had to reboot with the power button. Very slow boot, tried in single user mode. The console was stuck for a very long time on "still waiting for root device" but still boot after a while. After a few hours it went dead completely. Took it back to the shop, still waiting for their diagnostics.
 
I read an article in which the endurance of SSD were tested. After 200TB of data written on them, they are still going strong. So yours definitely seems premature.

Maybe try the HyperX SSDs or Intel SSDs.
