LaCie is a name to be reckoned with computer hardware systems and they have upheld their good name for ages now. The company name is synonymous with cutting-edge engineering techniques and aesthetics of design in the field of optical drives, hard disks, network and RAID solutions. They have been successful in providing solutions for providing back up for all your computer needs that they have almost set the standards for 4big Quadra range in Redundant Array of Independent Disks (RAID) technology. RAID technology is the most secure way of protecting data because it is able to heighten performance level and increase the capacity level. RAID helps users to customize the device to suit their requirements. Data duplication or division is made possible with the help of which there is a backup of files in case one hard drive fails. The success of a business lies in the choosing of a reliable storage device or backup solution. This paper documents the different basic RAID levels used in LaCie's storage devices and familiarizes one with important RAID terms like striping, mirroring and fault tolerance. The standard levels of RAID are described in the paper, they being RAID 0, RAID 1, RAID 3, RAID 3+ Spare, RAID 5, RAID 5+ Spare, RAID 6, RAID 0 +1 and RAID 10. The levels of Concatenation and JBOD are identified where concatenation means linking together two character strings by bringing together and JBOD just means a bunch of disks where the data is stored.
