Flash-based Solid State Drive (SSD) has been productively shipped and deployed in large
scale storage systems. However, a single flash-based SSD cannot satisfy the capacity …

Solid-state disks (SSDs), which are composed of multiple NAND flash chips, are replacing
hard disk drives (HDDs) in the mass storage market. The performances of SSDs are …

SSDs exhibit very different failure characteristics compared to hard drives. In particular, the
bit error rate (BER) of an SSD climbs as it receives more writes. As a result, RAID arrays …

While the move from SLC to MLC/TLC flash memory technology is increasing SSD capacity
at lower cost, it is being done at the cost of sacrificing reliability. An approach to remedy this …

The move from SLC to MLC/TLC flash memory technology is increasing SSD capacity at
lower cost, but at the cost of sacrificing reliability. An approach to remedy this loss is to …

With the explosive growth in data volume, the I/O bottleneck has become an increasingly
daunting challenge for big data analytics. Economic forces, driven by the desire to introduce …

Solid-State Drives (SSDs) are about to radically change the way we look at storage systems.
Without moving mechanical parts, they have the potential to supplement or even replace …

In this paper, a partial parity cache and data cache management method is presented for
reducing the parity updating cost of a solid-state disk (SSD) based redundant array of …

Redundant array of independent disk (RAID) offers a good option to provide device-level
fault tolerance for solid-state drives (SSDs). However, parity update with either read-modify …

Solid-state drives (SSDs) have been widely deployed in desktops and data centers.
However, SSDs suffer from bit errors, and the bit error rate is time dependent since it …
