The article reports on companies' use of self-healing storage systems to keep data residing on Serial Advanced Technology Attachment (SATA) disk drives viable and accessible. Self-healing storage systems use heuristics, journaling, read parity correction and distributed data resiliency in conjunction with Redundant Arrays of Independent Disks (RAID) 6 for higher levels of performance and data protection. According to Arun Taneja, consulting analyst and founder of the Taneja Group, companies need to ask themselves whether RAID alone is an adequate level of data protection when it comes to SATA.
