RAIDs are a popular solution for achieving reliability and performance for mass storage systems. Different RAID levels can be used to achieve very different objectives. In a short paper, discuss the pros and cons of RAID solutions. Compare throughput of RAID level 5 with RAID level 1 with respect to read operations on single blocks and multiple read operations on multiple contiguous blocks. Compare the performance of write operations of RAID levels 1 and 5.

Articles by Patterson et al., A Case for Redundant Arrays of Inexpensive Disks (RAID) (1988), and Chen et al., RAID: High-Performance, Reliable Secondary Storage (1994), present these pros and cons in extensive detail. Chen et al. are succinct in stating the two driving forces behind the adoption of RAID: performance and reliability (p. 145). Patterson et al., in proposing the RAID solution...
