    Hi, rekan-rekan DWH dimari.
    Saya punya Managed DS di Kabel Pohon.
    Saya kurang puas sama speednya.

    dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync

    Saya running command diatas via Root.

    Test 5X.

    1 : 131 MB
    5 : 99.X MB

    Rata2 100MB-an.

    Apa pengaruhnya signifikan I/O ini?

    Terima kasih.

    Kalau bukan SSD atau SAS, nilai itu sudah wajar.

    1 SSD (Intel S3500 120GB) untuk Storage utama.

    500GB HDD buat backup, bonus Coupun Code.

    Berarti ada yang tidak pas. Mestinya SSD setidaknya bisa 300MBps. Coba infokan 'fdisk -l; cat /etc/fstab'

    1. Partition terlalu banyak. Kalau saya, biasanya cukup / (root), /boot (kadang ditiadakan) dan /swap. Terlalu banyak partition bikin tidak efisien dalam pemakaian
    2. Biasanya IO size adalah 4096
    3. mount disk lambat akan mempengaruhi kecepatan keseluruhan
