Here is a report on several disk configurations that was done in 2009 using benchmark code bonnie++ (32-bit 2-CPU Athlon box):
which can be found in the Debian repositories.
Currently I use RAID10 with 4 SATA disks with LVM on top of the RAID on a virtual-machine server. I have not run the bonnie++ benchmarks on that system, but perhaps I will now that I see that there is some interest.
The only reason I would use RAID10 with less than 4 disks is practice (as with setup, etc), not for performance.
I am having some troubles with apt-get. I did an apt-get update and an apt-get upgrade. Some dependencies did not download, and so I had to do `apt-get -f install` to fix that. The thing is I get an error about /var/lib/dpkg/available

Hi,
another little question...
"sn" is an array whose elements can vary from about 55,000 to about 150,000 elements. Each element consists of an integer between 0-255, eg: ${sn} contain the value: 103 . For a decrypt-procedure I need scroll all the elements 4 or 5 times. Here is an example of... (15 Replies)
