That is usually called JBOD, or "just a bunch of disks".
kitamesume:
^ OH, found it instantly, thanks.
Edit: ok... comparing JBOD with RAID-0 and it looks like they don't have a difference, including the volume's contents dying when a part of the volume disappears except one that RAID-0 being faster.
well i thought it was like a "notebook" where ripping a page doesn't ruin the other pages and their contents.
Edit2: cant they make a software that makes a ghost drive and writes the files put on it on the drives assigned to the ghost drive? so that if the other drives dies the files would just go AWOL without touching the files written on the other working drives.
in layman's term, a secretary sorting your files on many drawers.

Uh, typical unix-like systems use a virtual filesystem. All files in all devices are seen by the user as a single hierarchy. Files saved on folders are written on whichever drive was mounted for that folder.
On windows, the closest ways I can think of is to use Libraries (in Win 7) extensively.
Pentium100:
You can mount drives as folders in an NTFS volume too (just like on Linux). To me, however, it does not solve the problem of having the free space divided into many drives (so I have enough free space for a new series, but I do not have enough free space on a single drive, so I have to write 2 episodes to drive 1, 3 episodes to drive 2 etc)
Anyway, if you use JBOD and one drive fails, it is the equivalent of a lot of bad sectors appearing on a single drive. You will lose all files that are in that drive (and all files that are partially on that drive). However, if the drive that failed, contained the filesystem information (MFT on NTFS), then you will lose all files.
However, I found FlexRAID. While the main function of it is o create a RAID of HDD image files, it also has a "flexraid-view" function, which creates a new drive letter, which combines all selected drives, that is, imagine I have two drives with these contents:
E:\anime\ep1.mkv
E:\anime\ep2.mkv
F:\anime\ep3.mkv
With flexraid-view I can create a new drive letter that combines these drives, so I get:
G:\anime\ep1.mkv
G:\anime\ep2.mkv
G:\anime\ep2.mkv
The only downside of it is IIRC that this is read only, if you want to write a new file, you have to find the drive with enough free space manually, otherwise flexraid will just write it to one drive and fail if that drive does not have enough free space.

@lupin
yea thats the problem, windows hardly has one.
@Pentium100
oh nice find, i'm looking into it right now XD.
