Methods and apparatuses for optimizing the performance of a storage system comprise a
FLASH storage system, a hard drive storage system, and a storage controller. The storage …

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 …

Current FTL schemes have inevitable limitations in terms of memory requirement,
performance, garbage collection overhead, and scalability. To overcome these limitations …

Random writes significantly limit the application of Solid State Drive (SSD) in the I/O
intensive applications such as scientific computing, Web services, and database. While …

Mobile devices use low-cost SSDs such as microSD cards and eMMC devices for persistent
data storage. However, The controllers of low-cost SSDs are optimized for reads and for …

Large-scale search engines use hard disk drives (HDD) to store the mass index data for
their capacity, whose performances are limited by the relatively low I/O performance of HDD …

Solid state disks (SSDs) can potentially eliminate the I/O bottleneck for many conventional
applications. However, they have a very unique characteristic of erase-before-write, which …

Random writes limit the application of SSDs significantly because of their poor latency and
high garbage collection overhead. Traditional page-based and block-based buffer …

Random writes significantly limit the application of flash-based Solid State Drive (SSD) in
enterprise environment due to its poor latency, negative impact on SSD lifetime and high …

Recently, NAND flash-based solid state drives (SSDs) have emerged as revolutionary
storage media. Numerous studies have been carried out to employ SSDs in database …
