Migrate RAID0 to RAID5 performance hit?

I have 3 mirrored disks (i.e. 6 disks in all) in one RAID0 set. all disks are 146GB.
I want to migrate to RAID5, but am concerned about the performance hit while the disks remap the 400GB of data.
How long will it take to remap, and what effect will it have on performance?
The system is a Proliant DL360 G4, Win2K3 Server connected to a MSA1000.
If anyone has any experience of a similar migration, your input would be appreciated.
Regards,
Peter

Hi,
this doc could help you:

migrate a logical drive - page 25, 53 (also the timing) and also the settings to speed up the migration/extension/rebuild processes
the pain is one part of the reality

Wow - 15 minutes per GB! = 100 hours. So it won't complete over the weekend...
Thanks for the info, might have to rethink the strategy!
