Will our Protools backup scheme work?
Speed and reliability are mutually exclusive goals. This translates to mean that you will need to pay more to get both. I’ll give you a concrete and simple example: RAID 0 and 1 mirroring. RAID 0 joins two smaller drives together into one “virtual” drive that sits on your desktop. Because there are two drive controllers, data is split up and written to the two drives much faster than to one physical drive. The downside is that should one drive in this arrangement fail, the data on both drives are lost. RAID 0 is how you find most disk enclosures sold to the digital musician and video crowds, because it is an easy way to add speed. RAID 1 takes two drives and mirrors the data on each. Data you write to one drive is written to the other. Writes take pretty much twice as long. Reads are generally not affected. If you’re doing a lot of multitrack recording (writing) then this is an issue. On the other hand, if one drive suffers a hardware failure, the other drive takes over transparently a
