RAID Config
I have 6 physical harddisks on my server. If I configure all HDD (total 5)to be RAID 5 including system disk (WIN2K OS) and with 1 HDD to be hot standby, will my OS crash if 1 of the HDD crashes in future?
TQ

Re: RAID Config
Side note .. why not setup RAID1 (100% redundancy) on 2 drives as your OS drives and the rest RAID5 (only need minimum 3 disks) as data disks ?

Re: RAID Config
Rather than use all 6 drives in a RAID-5 setup (or RAID 0+5/6), dedicate 2 drives to RAID-1 (mirroring) and use those for the OS. That still leaves you with 4 drives, more than enough for RAID-5, that you can use for data.

Re: RAID Config
I don't understand how some people still question RAID technology - it's been out for *years*. Thousands and thousands of production systems boot from RAID every day.
RAID-5 or RAID-1 does not matter. They both protect against single drive failures.
RAID-1 with only 2 drives is only margianlly more reliable than RAID-5 with 5 drives. Reliability should not be your determining factor here - but performance may be. RAID-1 will perform slightly better if your system swaps heavily. If not, the RAID-5 should perform the same or better than RAID-1.
Good luck!
