Re: Everything is for the Best in this Best of All Possible Worlds
This has nothing to do with disk performance of different computers.
This is about the differing performance of disk stores vs memory stores on the same computer, whether lightning fast SLC SSD or a 5400rpm slow laptop HDD. The speed of even the fastest SSD available pales in comparison to memory, it is an order of magnitude or more difference, with spinning rust being a further 1 or 2 orders further back.
At least, that is the consequence of Chrome's fix.
Therefore this issue already exists in multiple browsers from multiple vendors (i.e. Chrome, Firefox, probably others). Chrome has attempted to fix it with this fix, but this article is pointing out that this doesn't fix the existing issue. Or rather, it fixes the existing mechanism used to detect incognito, but introduces a new mechanism that is a little harder to use to detect incognito.
