Mount your disk (/mnt/) and try the following command(taken from the previous output):
dd if=/dev/zero of=/mnt/small.file bs=512 count=2050 oflag=direct
How much time does it take?
Best Regards,

hi,
I am using HDD : Toshiba 7200 RPM, Data transfer Rate 150MB/s, Interface 6Gb/s.
But Hyper-converged configuration stopped with error msg: Disk latency is very high,
time taken to copy 1M file is > 10s
Please help me to stop this error.
