SSD Write Endurance 25nm Vs 34nm

[Ao1]

I’ve just been trying to figure out the Samsung 830 data.

I’ve assumed:

• 5K P/E cycles.
• Host writes = F1*512/1,073,741,824 = GiB
• B1 RAW = P/E cycles count

It seems strange that the Host Writes per P/E cycles ratio remained consistently wrong until the theoretical P/E cycle count had expired. Once the theoretical P/E cycle count had expired the WA came out at; Avg 3.93.

It would be interesting to see how these results compared to another 64GB 830, however it seems it is possible to calculate host writes and approximate the MWI/ NAND Writes & WA using the basic SMART data that is provided. W/A is quite savage, but then again so are the sustained write speeds (at least until you get to MWI = 0).

Did anything come of the 470 autopsy? Is the 320 still going?
