SSD Write Endurance 25nm Vs 34nm

[Ao1]

As the V2 unthrottled drive has now written around the same amount of data before the V3 became throttled I thought I'd show a comparison. (I don't want to start a debate on the issue, but thought it was worth showing the comparison).

• The V2 dropped to MWI 87% whilst the V3 only dropped to 92% to write the same amount of data
• On avg the V2 dropped a MWI point per 2,420GB of data
• On avg the V3 dropped a MWI point per 3,752GB of data
• Reduction in writes between the V3 & V2 per MWI = 35%

The V2 = 32nm Hynix
The V3 = 25nm Intel

I doubt the V3 controller is that much better at reducing wear or that Intel's 25nm is that much better than the 32nm Hynix, so I'd guess that the MWI is linked in some way to LTT and the V3 was reporting the MWI "incorrectly". By this I'd guess more P/E cycles were depleted than indicated on the MWI, but LTT had not had a chance to correct the situation and bring P/E back in line with the MWI.
