    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):

    My results:

    XBench hasn't been updated since 2006. Its from before the days the general population could even buy an SSD.

    Compare with Blackmagic, or something similar

    XBench can still show semi-accurate results once averaged, but only for the disk tests. Most else it does is rather skewed.

    If anyone's curious, I was near an Apple store today so decided to run the test on 2 macbooks:

    (1) 2013 Macbook Air

    Pretty similar performance to my old macbook w/ an 840 evo.

    (2) 2013 Macbook Pro 13"

    Killer sequential speeds, but you can see 4kb random read speeds are similar for all of these.
