For a certain brand of indellix drive I calculated the life span in the following way. Based on the maximum sustained write speed of the drive and the size of the drive (256GB by the way) it would take 9 months to over write the entire drive 10000 times at 100% busy writing.

Did you consider the 'write amplification' factor? For example, if the SSD uses a 4K erasure block but only one 512-byte sector is updated per write? Tiny writes can wear out the SSD much faster than bulk write rates would suggest.

Just some food for thought.

More food!

The MLC drives seem to usually have more write latency than the SLC drives.
