    1. this is Intel DC p3520 according to serial number it is not a speedster (how other mentioned too)

    https://ark.intel.com/content/www/us/en/ark/products/93188/intel-ssd-dc-p3520-series-450gb-2-5in-pcie-3-0-x4-3d1-mlc.html

    It allready exceed the 4k random write specifics at IOPS (19000)

    600MB Write and 1200MB Reads speed are for sequential - click on question mark at Intel Site

    Sequential Bandwidth - 100% Read (up to)
    Speed with which the device is able to retrieve data that forms one contiguous, ordered block of data. Measured in MB/s (MegaBytes per Second)

    Sequential Bandwidth - 100% Write (up to)
    Speed with which the device is able to record data into one contiguous, ordered block of data. Measured in MB/s (MegaBytes per Second)

    You can test sequential speed with dd

    (Home PC drives are faster as they use large ram buffers and do not have power loss protection) ...

    2 Centos is not Ubuntu and do not execute trim weekly... with great probability drives are never trimmed
