    Trim command with SSD 400GB P3600




      I have an Intel SSD DC P3600 PCIe device. I use ext4 fs and kernel 3.16.0-34 from ubuntu 14.04.2


      I would like to ask two questions:


      1. What is the preferred way to enable trim on this device -- with the "discard"  mount option or using the scheduled "fstrim" command?

      Or  both?


      2. If I issue the "fstrim" command, it returns almost immediately. I suppose the SSD device continues discarding after the "fstrim" returns.

      How long (upper limit) can it take to trim 320GB or data, assuming that I did modified this data between discards?


      $ sudo fstrim -v /mnt/intel_ssd/

      /mnt/intel_ssd/: 322074972160 bytes were trimmed


      Thank you
