2GB writes per POH, too much for SSD?

I think you have to put it in context with the size of the drive. A month would add up up to 1.5 TB. You may want to check the numbers on the brand you have. How did you get too that 2 GB number ? Also, would it matter to you if instead of five years it only lasted three or four ?

IIRC the Intel G2 160GB with some little over provisioning can take well over 100TB. I have had one in a Lenovo W500 for a couple of years, W7, with a DB2 load on and off, inserting millions of rows, and I doubt I have put a dent on it at all. I cannot check the stats right now because it is off line due to machine upgrade to W520.
 
It's a 240GB Mushkin Chronos Deluxe, which has the 3x nm NAND, which should have higher write endurance than those newer 2x nm NAND chips.

It's still showing 100% health in SSDlife, 620GB writes, 300POH. 8 years estimated lifespan. I expect that estimate to change, once it shifts from 100% health, but I have no idea when that will be. Hopefully not too soon.

My 30GB OCZ Agility, under a similar load, was showing ~75% health, after like 5 months, and it had nearly 6TB writes.
Edit: The OCZ had the newest 1.7 firmware, which is supposed to help lifespan, by reducing WA.
 
From Xtreme Systems forums the 256GB Samsung lasted for 828TB before WMI went to 0.
60GB lasted Intel 520 419TB with compressable data.

Going by that your 240GB drive should be good for 600TB+ writes before MWI is exhausted. If your workload is more random it will be less though.

the datasheets I have seen (granted, Phison, not sandforce drives) typically state 10GB writes per day for 5+yrs
I think sandforce drives are better due to the low write amplification

I've also got a 64GB Micron C400 (aka Crucial M4) drive that has been doing constant write/erase endurance testing for a while now. The SMART values register that the drive is 178% used up!

Yea you can write way beyond the rated write cycles. The write cycle rating is the point where the drive should retain data for one year when left unpowered.
