I have a RAID 5 on my hard disks on my new computer but one time Ithe system crash and needed to force a reset there is no problem with that the problem is when windows logon again appear a messsage saying A volume initialization is in progress and takes hours and hours and not advance really 1% each hour or less. What can I do to avoid this? Maybe skip, because each bad reboot is needed to do this each time?
Thank you

I solved the issue I can increase the speed of the hard disk enabling write cache on intel storage software but your answer help me to understand the whole thing with raid configurations.

Well enabling the WC will make the rebuild go faster, but actually it increases probability of data loss.  I expect, however, your hands are tied, so back up often, and if you can, go to RAID1.  Your data is reasonably safe in that config as this is a tested configuration.

Do you like your data?  Do you want to keep it?  Then don't do RAID0.  Ignoring that ... if this is where you plan on putting the O/S, then most of the time overall performance will drop with RAID0.
RAID0 is good for sequential large block I/O.

Unless you are spending most of your time doing video streaming / editing on your PC, avoid it.

I see perfect raid1 then only thing is if I have 1.5tb on 3 hard disks of 500 gb each my final space after raid1 will be 750gb right?

The intel matrix can only do RAID1 with 2 disks, so if you have 3 x 500GB, then you would use 2 of them, for total of 500GB usable.  The 3rd disk could (and should) be in an external controller and used for archiving/backup purposes.   Attach when you want to backup. Detach, and store the backup somewhere else, like home or office.    RAID is no substitute for backing up.

(But do data compression to get you more usable space if you want)
