[Bio-Linux] Fresh install - partitioning?

Thu Oct 16 13:26:39 EDT 2014

They make a bit a confusion between RAID 10 (1+0) and RAID 0+1 (Mirror of
stripes).
Main difference between RAID 10 vs RAID 01

   - Performance on both RAID 10 and RAID 01 will be the same.
   - ...
   - So, given a choice between RAID 10 and RAID 01, always choose RAID 10.
