How much data can be written to a SSD before it fails?

As we all know, writing too much data to a SSD can kill it. So my question is, what's that number (approximately)? Or does that number depend on the time of Flash in the inside of the SSD?

2 1/2 megabyte.

Around 100 Terabytes would be a good estimate, which translates to a pretty long lifespan on normal use even if your temporary files are on it, although it's better to move them off.

Edit: I'm talking about 'consumer' grade 126/256GB ish SSDs!

Don't worry bro. It's enough for you to write all of your pr0n to.

On a serious note, multiple terabytes like FloRolf said.

I like the color scheme of Noctua fans. Deal with it. Forget about the bad memories of the past.

Forget about the bad memories of the past, take the good ones along with you through the present, and look forwards to the good things that will come in the future.

My 4K porn collection is already filling my two 3tb drives. I am using the SSD as an overflow currently

Entirely depends on the type of flash used in the drive, the firmware of the drive, and the size of the drive. Most consumer drives can take a few hundred TB, but write-oriented enterprise drives can usually handle somewhere in the double digit petabytes.

 

Edit: It also depends on the workload of the writes. Random writes kill SSDs faster than sequential writes because random writes incur an entire block-erase, meaning an entire block of flash is erased (say 64k) to update only a single page (say 4k). This is just a limitation of NAND flash itself. This phenomena of more bytes of flash being written than bytes of data actually written by the user is called write amplification.
