Not a really critical problem, more of a question out of curiosity. Couldn't really find any information about this on google.
So I own two idenctical 16 GB Corsair Voyager flash drives and i tested their performance with CrystalDiskMark 3.0.1. My first Corsair gave 29,9/6,3 as the sequential speed and the second one gave 34,2/14,4.
BTW: i used 50MB as the test size.
So my question is... Why do they differ so much? Does aging lower the performance of a USB flash drive in general?
