Hi all,
I just ran some Xbench tests on my old 2011 MBP + a samsung 840 evo SSD, but the random read numbers look suspiciously low.
I'm wondering if these are just odd for this particular benchmark, or if the 840 evo has trouble with OSX. FWIW, the drive is attached to my primary (SATA6) port, and TRIM is enabled.
Xbench here if you could please post your results and your machine specs (just need the disk test):
