What is a RAID Array?
A RAID array is a technology that allows two hard drives to look like one to the computer. The operating system will assign one drive letter to the drives yet spread the data across both/multiple drives - either doubling the throughput of the system or providing a "mirrored" drive (or perpetual backup) in the case of hard drive failure. There are many types of RAID arrays - the most common use in DAW's are RAID 0 and RAID 1.

RAID 0 Specs:

  • RAID 0 uses two hard drives as one with minimal overhead.
  • RAID 0 implements a striped disk array, the data is broken down into blocks and each block is written to a separate disk drive.
  • I/O performance is greatly improved by spreading the I/O load across many channels and drives.
  • Very fast, but requires separate backup strategy

RAID 1 Specs:

  • RAID 1 provides fault tolerance as all writes are duplicated on both drives. 
  • 100% redundancy of data means no rebuild is necessary in case of a disk failure, just a copy to the replacement disk.
  • Transfer rate per block is equal to that of a single disk.
  • Highest disk overhead of all RAID types (100%) - inefficient but safe.

So what does this mean for my DAW?

A DAW configured with a RAID 0 array and 150 MB/Sec. Serial ATA Drives (like our SATA machines) can provide up to 300 MB/sec. throughput under optimal conditions and blow away typical ATA 100-based systems in testing. Throughput numbers can reach very close to a high-end SCSI based systems' peak performance with minimal overhead.  If you're using your DAW for tracking, mixing, editing, or all of the above, you need this technology to reach maximum track counts with minimal problems. RAID 0 SATA will speed up all data transfers, whether during tracking or session backups and loads. You can also partition a RAID 0 into 2 logical drives for easy backups and defrags so you get great performance and easy backup capabilities. 

A RAID 1 based DAW duplicates all writes on both drives to provide an online backup or "mirror" of session data. Therefore, your performance will actually be lower than a single non-RAID 1 configuration. The trade-off is recovery from a failure is much faster. This configuration is not recommended for DAW's unless 100% reliability/zero downtime is more valuable than the performance of the DAW. 

Is this technology reliable?

Yes. The mean time between failure for the drives we use in our RAID 0 array-based machines is upwards of 5 years of constant use. They are as reliable as your typical ATA 100/133 7200 RPM drive. The performance gain for the price cannot be beat. Just be sure to backup your data on a regular basis to the supplied removable/swappable backup drive(s) to ensure your sessions are safe.
