According to Platypus, these RAM-based drives achieve throughput of up to 110MB per second (compared with up to 35MB per second for disk-based drives), and 15,000 to 20,000 I/O transactions per second (compared with 200 to 300 for mechanical drives).
Therefore, they're ideal for speeding up Web sites, databases and proxy-cache servers, and for delivering streaming data and obtaining maximum virtual-memory "swap space" performance of the sort that users of Adobe Photoshop rely on.
The QikDrive's storage subsystem and controller subsystem are located on a single PCI card. The list of supported operating systems includes Mac OS, Windows NT, Windows 2000, Linux and Free BSD; this list is growing.
Despite being internal to the host computer, the QikDrive has its own power supply, for data security.
In Australia, QikDrive1 (with a maximum capacity of 1GB) and QikDrive8 (which holds up to 8GB of data) are distributed by Express Data. Suggested prices vary according to configuration. A 512MB unit costs $2,500 Australian (about $1,538 U.S.), and a 4GB drive costs $16,000 Australian (about $9,840 U.S.). The company, which is based in Crows Nest, New South Wales, also has sales offices in Woodstock, Vt., and Hungerford, England.
