This "Write Endurance" is the term for these NAND flash chips in SSD?? I wasn't sure if if was read, write or both.
(Sorry for the newbie questions)
Keep free, over the air television alive. Wireless services occupy enough spectrum already, they don't need any more. Free, OTA TV is what makes this country unique.
I've been toying with a new SSD as my current 60GB SSD (bought a couple of years back) has always been irritatingly small but probably going to stick with it as a larger one isn't going to be enough to fit my data on anyway and it forces me to keep data off the OS drive which makes reinstalling a lot quicker.

Correct. Write Endurance = number of write/erase cycles the NAND is good for.
45nm MLC NAND = 10000 w/e cycles per cell
32nm MLC NAND = 5000 w/e cycles per cell
2xnm MLC NAND = 3000 w/e cycles per cell
Seems like a drastic reduction, but even with the modern SSD's using 22nm flash (or 25nm), they are rated (due to spare area, wear leveling, etc.) for well over 5 years of normal use as mentioned by kent1146.
If you don't want to feel like a newbie anymore check out Anandtech's SSD anthology. It explains all of the basics in a way that is very easy to understand.
