Ubuntu's performance : how to speed up ?

[Behrang Saeedzadeh]

You can also bundle two HDDs in "hardware" RAID-0 configuration to get
about twice the peformance of a single HDD system.

In RAID-0, for example, when you want to save a 10meg file, half of it
will be stored on one of the disks and the other half on the other
one, simultaneously, so you double the peformance. This is also the
case for reads.

You can also consider RAID-5 ;) It offers you three times the
performance of a single HDD system plus data backup :) Having said
that, I've never heard RAID-5 setup on desktop PCs or workstations.
