I want to upgrade internal HDD space by combining an external HDD via win8 buil-in feature called 'pool' (aka Storage Spaces).Now the problem is in "Resiliency Type" there's an option 'two waymirror' it says that it will make two copies but how it'll duplicate a file being written on it.Because it has to rename both files different such as for example I save a file named "Docula.txt" then it has store two like one "Docula.txt" and other with "Docula(1).txt" it can't just place them with the same name(Correct me here if I'm wrong).

Although I've also heard about this 'RAID' what I know that its a combination of HDDs with different levels that is 0,1,5,6 etc.So the question where RAID is premarily used.And why people mostly avoid it because when I asked a few people about 'RAID' they mostly replied that "Don't go with it unless you're experienced".Some said don't combine your HDDs just use them seperately via USB ports.

Thanks for your consideration.

RAID 0 - If you want to combine two drives for faster response. No backup or redundancy. If either drive, or the RAID controller fails, all is lost. 2 x HDD in RAID 0 is still slower than a typical SSD

RAID 1 - Mirrored data between two or more drives. If you need absolute uptime. Say if you were running a webstore. 1 drive dies, and the system is still running until you can replace the bad drive. Downtime = lost money.
It is not a backup. Any reputable business that runs their system on a RAID 1 also has an actual backup.
Yes, it is a mirror between two drives. It also faithfully mirrors any deletions, accidental or otherwise, any corruption, viruses, whatever.

There are other levels, as referenced above.

Well, if you choose the "two way mirror", thats exactly what it does. Same files on two drives, for a theoretical resiliency.
Not sure how Storage spaces handles the same file name, but it should be simply two copies of the exact same file and filename. Just mirrored on two drives.

I'll do it.Thanks for your contribution.Premarily I want to know that where this 'RAID' is usually used.Apparently,I guess that it is used by remote servers or cloud services.But what's your idea anyway?
