    Raid 5 - Slow Write Speeds


    I am trying to setup a raid 5 using 3 4tb HDD. Once I create the array I am only getting about 60MBps writes, while each drive is capable of about 200MBps. I have enabled write cache on all drives. Any ideas?

    Slow write speed of transfer

    My dell 7577 core I7 1050ti model has a slow transfer speed. I transferred a 5 gigabyte file to an external USB 3.1 Kingston DT50 and I got write speed of 8 MB/s. and the read speed was capped at 21 MB/s although
    I used to get at least 80 MB/s read speed. Please help!
