    Pár teszteredmény a BPI M2U lapról.

    eMMC:

    root@bpi-m2u:/mnt# flash-bench

    Nem a leggyorsabb eMMC, pár s905 box ráver.

    SATA HDD:


    root@bpi-m2u:~# hdparm -I /dev/sda | more

    root@bpi-m2u:~# hdparm -t /dev/sda

    /dev/sda:

    root@bpi-m2u:/media/Nas# flash-bench

    Ezen azért látszik hogy nem USB-n lóg.

    A kissé módosított Raspberry Pi Benchmark ezeket mérte:

    AikonCWD's rpi-benchmark completed!

    A hálózaton másolás azért már nem hozta az x86 alapú pc szerverek 100 mega feletti tempóját.
    Ebben a mérésben, NFS fájlrendszeren 1 giga jött át.

    Mint18 ~ # mount 10.1.1.1:/media/Nas /mnt
    Mint18 ~ # dd if=/mnt/test.img of=/dev/null bs=1M
    1024+0 beolvasott rekord

    1073741824 bájt (1,1 GB, 1,0 GiB) másolva, 28,1975 s, 38,1 MB/s

    Végül hálózati tempó, itt a bpi volt a server, a pc a kliens, itt megvan a gigabit.
