Storage systems employ redundancy and recovering schemes to protect against device
failures and latent sector errors, as well as to enhance reliability. The effectiveness of these …

Today's data storage systems are increasingly adopting low-cost disk drives that have
higher capacity but lower reliability, leading to more frequent rebuilds and to a higher risk of …

A recent article on the reliability of RAID-6 storage systems overlooks certain relevant prior
work published in the past 20 years and concludes that the widely used mean time to data …

The reliability of disk storage systems is adversely affected by the presence of latent sector
errors. Disk scrubbing and intradisk redundancy are two schemes proposed to cope with …

The low-cost disk drives, which are increasingly being adopted in today's data storage
systems, have higher capacity but lower reliability, which leads to more frequent rebuilds …

Two schemes proposed to cope with unrecoverable or latent media errors and enhance the
reliability of RAID systems are examined. The first scheme is the established, widely used …

Detailed dependability models of various disk array organizations are developed taking into
account both the hard disk failures and transient errors. Various error and failure modes of …

Erasure-coding redundancy schemes are employed to ensure improved reliability of storage
systems against device failures. The effect of the lazy rebuild scheme on the Mean Time to …

Today's data storage systems are increasingly adopting low-cost disk drives that have
higher capacity but lower reliability, leading to more frequent rebuilds and to a higher risk of …

The reliability of data storage systems is adversely affected by the presence of latent sector
errors. As the number of occurrences of such errors increases with the storage capacity …
