Using multiple drives for audio production
1) System drive (SSD): This one should hold your program application
2) Samples and Libraries (SATA3-7200RMP): This one holds your packs, samples and sound libraries (SSD recomended)
3) Audio Recording and Caching (SATA3-7200RMP): This is especially key if you are using higher bit rates for your audio recordings (SSD recomended).
4) Backup (Any type): This is to have a backup of your files etc (deons’t have to be SSD).
