Mirrors and RAID

Mirrored server hard drives are a great idea in the dental office. A mirrored hard drive also called a RAID array (Random Array of Inexpensive Disks) copies all the essential data instantly to a second hard drive. This gives you great protection against hardware failures.

RAID systems can be set up in five different arrays ranging from RAID 0 to RAID 5. In dentistry we do not need fancy (and expensive) SCSI RAID 5 systems. A simple (and inexpensive) IDE mirror works great.

Two vendors make IDE RAID controllers Arco form Florida and Accusys from Taiwan. An IDE system including two hard drives and installation should cost less than $500.
