Software RAID5

["Jean-Luc Coulon (f5ibh)" <jean.luc.coulon@gmail.com>]

Hi,

I've a system with a software raid1 on 2 sata drive 80 GB
I've all my system on LVM on this underlying raid.

For performances reasons (video editing), I'm thinking if a RAID5.

Is there somebody with some experience with raid5:
- performances
- behaviour in case of a crash

Is there an easy process to migrate from raid1 to raid5 without  
reinstalling everything?

Regards

Jean-Luc
