Note that that was a QD3 test (3 queue depth), and there's where Samsung drive shine. If you compare just 1 queue depth random read, Toshiba is indeed a little better though no by a lot. When you have bunch of queued random read commands you can see Toshiba is falling behind.Toshiba: 1.65 MB/s 4k random read
Samsung:27.2 MB/s 4k random read
Will the end user notice the differences? Most probably no.
