A new solid-state disk went on sale this week that will vastly accelerate the performance of relational databases such as Oracle 10g, IBM DB2 and Microsoft SQL Server, returning important queries on business data much faster.

A solid-state disk is a storage device that contains no moving parts. It uses RAM memory boards, and its own processor to manage data storage, making it a lot faster than a conventional rotating hard-disk device. IT managers often use solid-state disks alongside enterprise storage systems from EMC, Hitachi, IBM and others.
Texas Memory Systems’ RamSan-400 has multiple 4Gbit Fibre Channel interfaces, and can sustain 3Gbytes a second of random data transfers, making it the world's fastest storage, according to the firm.
Claus Egge, European storage systems research programme director at analyst IDC, said, "This sort of device used to be used with mainframes and has more recently been applied to databases. It is massively fast."
Donald Burleson, president of the Burleson Consulting Group, said RamSan products had in the past provided database performance improvements of up to 300 times. Tests with Oracle 10g are under way, but he added, "We expect this new solid-state disk to be the fastest high-speed I/O device for Oracle databases anywhere on the planet.”
