SiSoft Sandra 2001 Performance Index
Sandra shows results similar to those of the Disk WinMarks. Using two drives will increase your overal storage performance, while anything beyond that makes a smaller impact.
Windows 2000 support for stripeset media proves to be a mighty utility. Depending on the amount of drives, you can boost data transfer rates up to the limit of the PCI bus (133 MB/s in theory). In systems with 64 Bit PCI, you can even reach much faster performance - provided that more drives and more controllers are deployed. Many applications are programmed in order to run most of the source code in the processor cache or the main memory, so the hard drive performance becomes secondary.
Software stripsets are just perfect for high-performance temporary storage required by demanding applications. You could, for instance, use stripeset drives for Windows swap files or for data that tends to remain static and are frequently backed up (e.g., software that is regularly installed over a LAN). It is not recommended for data storage, since the data is at a much greater risk than with single drive configs or redundant drive arrays, so don't go storing large databases and other important files on striped drive arrays.
