I have an old OCZ Vertex 4 256GB drive. I am trying to see how much life the drive has left. It is ~9 years old, but seems to run well.

Here is the smartmontools output under Linux Mint 20.2

Code:
sudo smartctl -a /dev/sda

Solution
Lifetime writes on that drive seems to be a sector (512B) in size. 11198350898/1024/1024/2 = 5340GB = 5.34TB written, if I'm correct.

The Vertex 4 I believe uses Intel's 25nm planar 2-bit MLC. I think this was rated for 5k PE cycles, which for a 256GB drive would be around 1.28PB, not accounting for write amplification, ECC, etc.

You won't be wearing out the flash, it will die from something else.

Don't worry about life time or writes left, it's completely arbitrary, it may die next minute or last way past any estimates. What manufacturer states as TBW is just for warranty purposes. More than often in normal use and if nothing goes wrong, they will last way longer.
