SSD Write Endurance 25nm Vs 34nm

[Ao1]

For the 520 NAND writes (249) = 1iGB increments. For host writes (241) a value of 1 = 32GiB, so in the example below 2,656 = 83GiB for host writes vs 80GiB nand writes.

The threshold for the media wear out indicator is 0, unlike non Intel SF drives, which have a threshold of 10.



For the SF2xxx NAND writes (233) = 1GiB increments. For host writes (241) a value of 1 = 1GiB



For the SF1xxx NAND writes (233) = 1GiB increments. For host writes (241) a value of 1 = 1GiB



For the X25-M NAND writes are unknown



For the Samsung 830 host writes (241) 1 raw increment = ( 1 * 512 ) / 1073741824 = GiB.

Medial Wear Out Indictor =
Wear Levelling Count (177)
Raw value /5,000 *100 = x ( 100- x) = % remaining life
10/5000*100 = 0.2 (100-0.2) = 99.8%
