Day 1

Today there was nothing suspicious going on. The drive was working the way it is expected to be working. So far we've managed to write 5500 Gigabyte. If we check "Total Host Writes" and compare them to "Total NAND Writes" we can make a different assumption. I looks like this makes the actual "Write Amplification Factor" of the drive visible. Since the host writes stand for the actual amount of usable data that has been written, the "Total NAND Writes" show how much data acutally had to be written in order to store that amount of data. Let's dived "Total NAND Writes" by "Total Host Writes" and we might have a good approximation of the actual write amplification factor of this drive. In this case there appears to be a WAF of 1.46. Since this value is somewhere in the between 1 and 2 it is really good.
