Following a HDD crash where i lost most of my data i am building a new PC and am considering using RAID for data redundancy.
I read through the FAQ and other online materials but still have some questions on what's the best RAID setup for me.
Core i5 4670k
Asus Z87 Pro mobo
Win7 ultimate on SSD
1 WD 2T Red HDD with pics, videos, personal docs (will get more HDDs to setup RAID)
I would like to use RAID only for my personal data on the HDDs and not for the SSD where Win7 and my programs reside (it's only about 50GB so i can create a bootable back up image easily).
Q1: Can RAID be configured to only mirror the HDD data and ignore the SSD where the OS is?
Q2: i already have data on the HDD. If i set up RAID5 or RAID1, will this erase the existing data? I will do a clean install of the OS on the SSD but would like to keep (and duplicate) the data on the HDD.
Q3: I like that RAID5 uses less HDDs and still provides redundancy. The Z87-Pro motherboard supports HW RAID5 but Win7 doesn't support SW RAID5. If i set up HW RAID5 through the motherboard, will it create issues or limitations when i use it in Win7? Would you recommend using HW RAID 5 in Win7?
Thanks for your help.
I'm assembling a PC for the first time so RAID is really pushing the limits of the technical expertise
A safer bet is simply another copy of your important data, on another drive. Say an external. Even safer is two externals, one off-site. Rotate weekly.
RAID can only protect so much. It will faithfully reproduce accidental file deletions, viruses, file corruption, etc.
A disconnected drive still has a copy of your original file, no matter what you do to the working copy on your PC.
It's great for constant access if a drive dies. Not so much for data integrity and backups.
