RAID Level 1 - Page 23

segments — or stripes — of data sequentially across the physical drives to create a large virtual drive. Data striping allows one of the drives to read data while the other drive is searching for and reading the next block. Another advantage of a RAID level 0 configuration is that it utilizes the full capacities of the drives. If you have two 120-GB drives installed, you have 240 GB on which to store data. RAID Level 1 RAID level 1 uses a data-redundancy storage technique known as "mirroring." When data is written to the primary drive, the data is then duplicated — or mirrored — on ..

Setting Your Computer to RAID-Enabled Mode - Page 24

Because data is striped across the RAID configuration, as it is in a RAID 0 configuration, it can be quickly accessed. Also, because of the parity data, if only a single drive fails, that drive can be rebuilt using the parity data on the other drives. The amount of storage space available to three 120-GB RAID level 5 drives is 240-GB on which to store data, since the equivalent of one drive is set aside for parity data. A minimum of three drives is required to create a RAID level 5 configuration. Configuring Your Computer for RAID At some point you may want to configure your computer for RA..
