Using RAID

Go Up to Distributing I/O

You can achieve up to a ten times performance improvement by using RAID.

RAID (redundant array of inexpensive disks) is a hardware design that is intended to give benefits to performance and reliability by storing data on multiple physical disk devices. It is transparent for software applications to use RAID, because it is implemented in the operating system or at the hardware level. InterBase uses operating system I/O interfaces, so InterBase supports RAID as would any other application software.

Disk striping (included in RAID levels 0, 3, or 5) provides performance benefits by distributing I/O across multiple disks.

Hardware RAID is faster than software RAID or software disk mirroring. RAID implemented with software provides only protection from hard disk failure; it is actually slower than operating without RAID.
