Comment on Data HDD with SSD catch drive

The cool thing about rsync is that it goes ”BRRRRRRRRR!” like a warthog… the plane… and it can saturate the receiving drive or array depending on your network and client. And getting 180 with rsync… on a SATA drive, can’t really hope for more.

And you can run a quick n dirty test is using dd

$> dd if=/dev/zero of=1g-testfile bs=1g count=1

Thx. Ive seen dd commands in guides how to test drive speed, but I’m not sure how can I specify what drive I want to test. I see I could change “if” and “of”, but don’t trust myself enough to use my own modified commands before understanding them better. Will read more about that. Honestly I’m surprised drive speed test is not easier, but its probably just me still being noob xD

  Let’s say you want to test a drive that is mounted on /tmp… you just cd into that directory and you can use my example.
  
  You can use
  
  $> df -h or $> mount
  
  to check how your drive is mounted in the OS Most ”default ” installations will have 1-4 partitions and / being partition 3 or 4.
  
  So if you look at the mount command and / is /dev/sdX3 (where X can be a-z depending on how many drives you have connected) and no other mounts are in the output then every directory under / is on that drive… so you can run my example from your home-directory if you fancy that.

    Thank you a lot for being patient with me :D
    
    dd if=/dev/zero of=1g-testfile bs=1G count=1 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 4.62269 s, 232 MB/s
    
    This HDD is obviously working fine and much faster than I thought it can. I guess I have to find bottleneck elswhere
