Disk speed test Linux

Just recently I was wondering what my quickest disk on my laptop was to store some files. I ran across a nice Linux tool that is worth sharing here: hdparm
Accessible as root (or sudo).

There are many options (just run it without any params to see them), but what I used was:

hdparm -tT /dev/sdb1

with this result:

/dev/sdb1:
 Timing cached reads:   12622 MB in  2.00 seconds = 6315.83 MB/sec
 Timing buffered disk reads:  76 MB in  3.05 seconds =  24.92 MB/sec

The above results are from an USB disk, but I also ran it on my internal disks.

For the fun some results.

USB strick
/dev/sdd:
 Timing cached reads:   10842 MB in  2.00 seconds = 5424.47 MB/sec
 Timing buffered disk reads:  38 MB in  3.02 seconds =  12.57 MB/sec

USB disk
/dev/sdc1:
 Timing cached reads:   15708 MB in  2.00 seconds = 7860.72 MB/sec
 Timing buffered disk reads:  74 MB in  3.02 seconds =  24.47 MB/sec

SATA disk
/dev/sda3:
 Timing cached reads:   13126 MB in  2.00 seconds = 6568.08 MB/sec
 Timing buffered disk reads: 258 MB in  3.01 seconds =  85.83 MB/sec
