1) I am considering spanning 3 x 3TB Seagate Barracudas (ST3000DM001). I am NOT looking for performance gains since i don't want a lack of redundancy. it would be purely video/backup/archive and the ease of not having to copy/paste from the individual drives as well as not having one drive full with say video editing material and another of backups being half empty is what appeals to me. I want to know if one drive fails can i still access the data on the others? Would that be via windows or using recovery software like reecuva; i heard somewhere that even span/jbod means you loose one drive you loose it all since the MFT? data for all drives is stored all on one drive?

2) Also could i add more of the same drives to the array in the future without having to rebuild the array or any other issues? I would have course keep fair backup normally and more or less full backups before doing this procedure.

3) Is this drive span/jbod/raid compatible; any issues with software raiding a drive with smart align technology? Thanks
 
Are you ever going to utilise 9TB of data, though? :/ I would personally just use 3TB for downloads, 3 for installs and 3 for important backups....

I don't think spanning is completely fault tolerant. Mirroring would be the way to go especially if you have 3x3TB......
 
With JBOD you have no redundancy. Assuming NTFS, if the MFT is on disk 2, and disk 2 fails, then you're pretty much screwed. Also if disk 1 fails you'll lose the location of the MBR - you could potentially recover from this though by scanning the other disks.

I can't really think of a use case where JBOD is going to be better than RAID0, unless of course you're doing it all in software.

This would be a software raid spanning/JBOD in windows 7; does that still mean that if one drive fails i could loose it all? Seems kind of silly if that's true. Thanks
