    write&read-back iops for DC S3500

    steveau

      I am testing my DC S3500 SSD. I found the write iops and read iops are all OK.

      AS SSD:

      4K bytes read 7K iops,       

      4K bytes write: 15K iops

      512 bytes read 18K iops    

      512 bytes write 18K iops    

       

       

      Mixed read /write still alright:

      Diskspd:

      random 4k bytes 50% read, 50% write: 6k iops.

       

       

      But when I tried write & read-back, i.e. random write but immediate read back from same position, I got terrible figure:

       

       

      random 4k bytes write then read-back:  1000 iops only.

       

       

      Is there anything wrong for write&read-back?

       

       

      Regards
