Churchill said "it is difficult to make predictions, especially about the future".
I will not try to do so. In this blog I just mention two approaches to solve the I/O bottleneck using Solid-State Memory in different flavors.
The Advantage of these approaches is that only the storage layer is changed and everything else - especially the applications - remains unchanged thus boosting performance of your oldest legacy code without modifications.
Kaminario offers a DRAM storage appliance called K2 which replaces the traditional disk storage "in one day". K2 keeps all your data in main memory. Data is mirrored onto hard disk for recovery. Kaminario claims up to 1.5 million IOPS for the K2, which proposes the K2 as a storage for IO intensive applications.
Of course there are also offerings that replace the hard disks with fast SSD discs as n you MacBook Air.
Teradata recently announced the Extreme Performance Appliance 4600.
Schooner Information Technology offer an MySQL appliance which uses SSDs instead of hard disks.
FUSiON-IO offers a set of ioDrive SSD solutions.
Violin Memory offers the 3200 Memory Array.
Texas Memory Systems offers several RamSan solutions.
