Stripped mirroring RAID architecture
2000
Journal of systems architecture
Preserved Fulltext
The disadvantage of RAID-1 lies in excessive redundancy, while the write performance of RAID-5 is only 1/4 of that of RAID-0. ...
In this paper, we propose a high performance and highly reliable disk array architecture, called stripped mirroring disk array (SMDA). It is a new solution to the small-write problem for disk array. ...
Modeling and performance evaluation In this section we present a utilization-based analytical model to compare the I/O access performance of RAID-0, RAID-1, RAID-5, RAID-10 and SMDA. ...

In this paper, we propose a Hybrid Parity-based Disk Array architecture, HPDA, which combines a group of SSDs and two hard disk drives (HDDs) to improve the performance and reliability of SSD-based storage ...
In HPDA, the SSDs (data disks) and part of one HDD (parity disk) compose a RAID4 disk array. ...
Menon [37] proposed a log-structured array (LSA) that combines LFS, RAID, compression and non-volatile cache to improve the write performance of RAID5. ...
