[Bio-Linux] Fresh install - partitioning?

[James Mategko]

Hi All,

   The following calculator is very helpful when planning arrays: 
http://www.raid-calculator.com/default.aspx

I use RAID 5 most of the time since I tend to work with my datasets in 
memory rather then write intermediate steps to disk. I'm planning on 
moving to RAID 10 when larger capacity HP ProLiant compatible HDDs/SSDs 
come down in price.

Best Regards,
- James
