I am pulling in a few articles from my other site which are better suited here.

Well, I have been planning to launch this site for a while now. A place to pay homage to the all mighty terminal in all of its glory.

So what kind of performance should people expect from a disk or raid?

How long should it take to create 100G file?

time dd if=/dev/zero of=mako1 bs=65536 count=163840

A customer of ours is using this to create a 10G file and its taking about 20 minutes to create the file on a 12 drive raid 5 with 3ware. After setting ra again (in case the customer did not) and I got about 18 minutes on the same command.

The customer says we should be able to create that file in about 10-20 seconds. ref (http://t2.unl.edu/ce-changelog/dcache04-performance)
