SSD Write Endurance 25nm Vs 34nm

You guys do realize that the Intel 320 series probably has over a thousand blocks it can use for reallocation. So, at the seemingly linear rate this test is currently moving, we could be well into multiple petabytes before the 40 GB 320 runs out of blocks it can use for reallocation. I mean, what's a page on a modern SSD, 8KB? The page size actually is exactly 8KB on the 320, IIRC? If I remember correctly, the block size on the 320 is 2MB, and we all know erases are done in blocks and not pages. How much spare area is there? 8-12 %? So, worst case, we're talking 40GB * 8% / 2MB = 1,525 blocks. Since, we're really most likely reallocating blocks and not sectors, I am not sure how to read the graphs to see where we're at in terms of reallocated blocks.
