Did you not read the link? They use 96GB out of 160GB. 64GB is available to do all the write combining SSD needs to do. That test is not full span. Full span implies the full 160GB is used.

You don't seem to understand why what they are claiming is impossible. Even if what they are doing is absolutely the easiest workload imaginable for the Intel SSD (it isn't) and the write amplification is 1 (can't get below 1, unless compression is used which Intel does not do), then they claim to have overwritten each cell 25,000 times. This is 5 times more than the spec for 34nm MLC flash. No matter how magical you believe the controller to be, it can not do anything to increase the raw life of the NAND which is being used. The absolute best the controller can do is not waste any write cycles on unnecessary operations.

If the flash cells could withstand 25,000 writes and still operate, the manufacturers sure as hell would not be marketing it at 5k.
