Intel Matrix Storage Manager Quick Guide for Acer Selected Veriton PC V1.15/212. RAID Technology and SelectionRAID (a redundant array of inexpensive disks, also later known as a redundantarray of independent disks) is a system that uses multiple hard drives to shareor replicate data among the drives. Depending on the version chosen, the benefitsof RAID are one or more of the following: greater capacity, reliability,protection of data, and/or speed compared to a single drive.RAID0 (striping)• RAID0 splits data evenly across two or more disks with no parity informationfor redundancy.• Multiple files can be read (and written) simultaneously and transfer timeis improved dramatically, thus increasing throughput.• RAID0 volume capacity = number of (HDDs) x (capacity of smallest HDD)• RAID0 can be created with disks of differing sizes, but the storage spaceadded to the array by each disk is limited to the size of the smallest disk.For example, if a 120 GB disk is striped together with a 100 GB disk, thesize of the array will be 200 GB.B lo c k 8B lo c k 7B lo c k 6B lo c k 5B lo c k 4B lo c k 3B lo c k 2P h y s ic a l d is k1 2 0 G BP h y s ic a l d is k1 2 0 G BL o g ic a l d is k2 4 0 G BP h y s ic a l d is k s L o g ic a l d is k sB lo c k 7B lo c k 5B lo c k 3B lo c k 1B lo c k 8B lo c k 6B lo c k 4B lo c k 2B lo c k 1D is k 1D is k 2 R A I D 0
