What is RAID?
RAID, or Redundant Array of Independent Disks, is a method for storing data on multiple hard disks, then linking the disks so that the operating system on your server views them as a single entity. At GalaxyVisions, we offer RAID for both SATA and SCSI hard drives in 3 different configurations with our Dedicated Servers: RAID-0: This type of RAID uses a method of data storage known as striping. The technology divides the data into pieces, and places each piece on a different drive. For instance, data piece A may be stored on Drive 1, while data piece B goes to Drive 2, C heads to Drive 3, and so on. Because the data is divided, RAID-0 offers the top level of performance for disk IO. It is usually used for multimedia applications like video editing and for situations where data loss is not as much a concern as speed. RAID-1: This type of RAID uses a method of data storage known as mirroring. This refers to the fact that every piece of data is written to at least two disks. As a result,
RAID – Redundant Array of Independent Disks – is an evolving storage technology that offers significant advantages in performance, capacity, reliability, and scalability to groups of users that have requirements beyond those offered by a single PC. RAID systems provide high reliability and data availability through techniques such as parity checking. In this scheme, when the RAID controller writes information onto the disks, it also writes redundant information called parity bits. Should a disk fail, this parity information enables the RAID controller to re-compute the lost information as it is requested without degrading performance. Advanced RAID controllers will reconstruct the lost data onto a spare disk, so that the system can survive another disk failure. With increasing demands for mass storage performance, capacity, scalability and reliability, many companies are adopting RAID technology to complement their existing computer systems, enabling them to support demanding applicati
