Reformatting Drive for Music Production?

Any reason why you want to use RAID? Does your external drive even support it?

When you say “storing the project” do you mean you are building the project on the external drive, or just backing up?

There is no particular reason, but it is an option from where I must choose from those 3 settings I mentioned above and also the RAID Block size. Remember I am formatting for Mac usage not PC. Building the project on external drive for building the project.

RAID is no replacement for regular backups. If you don’t absolutely have to create a RAID on this disk, don’t do it. It is not commonly used in music production, where data read and write is generally more linear than random, and data loss is a very bad thing.

Mirrored is slower than a single disk for writes, Striped is dangerous (you double the chance of disk failure), same problem with concatenation.

“The Mac OS X 10.4 implementation – called a “Concatenated Disk Set” – does not leave the user with any usable data on the remaining drives if one drive fails in a concatenated disk set, although the disks otherwise operate as described above.”
