HowTo: Measuring hard disk performance with linux and ‘hdparm’
Nov 5th
Measuring sequential disk performance with linux is easy – most distros (like ubuntu) come with a tool called hdparm , that is mainly used for tuning and optimizing hard disk parameters, but luckily it also includes simple benchmark functionality – for example the following command sudo hdparm -t /dev/sda gives me the following output: /dev/hda: Timing buffered disk reads: 176 MB in 3.01 seconds = 58.55 MB/sec Of course you need to substitute /dev/sda with the name of your raw disk device (for example, it might be /dev/hda for non-SATA disks) . Its impossible to get higher transfer rates that that from your disk.

So far so good, but what about all those thousands of customers that already bought an eeePC 1000H before? Are they doomed to use one of those ugly external USB 3G modems – a threat to your eeePCs health if you drop it accidentally and the USB stick destroys the USB port it was sticking in (if not even more)…
