From what I understand these were cherry picked parts from
a normal production run. Has anyone heard if this is a new
production process or a new concept in SSDs? BTW - Samsung
has reported 500K rewrites from cherry picked parts.
I thought the Samsung parts were actually a production run (low yield).
I hadn't heard that they had done a cherry pick on the existing process.
If they are cherry picked, then it's not really a turning point
in SSDs. It also bothers me that a normal production run can
have parts with rewrites at 100K and 1M. Sounds like there
are some variabilities that can't be controlled.
Similar things happen with RAM.
Don't forget that 100K rewrites are SLC products and MLC's
are general 10K. Although the Intel drives state 100K with
MLC (and pretty decent performance). I'm not sure of the

I can't find the Intel P/E cycle, but the Ridata units are 2x10^6 (2E+6).
