DiskTT will measure a disk's 32-bit thruputs using Windows core read/write features.

Your actual disk perfomance under Windows is determined not only by the speed of your harddrive (as measured by most disk benchmarks) but also by factors such as the mainboard chipset, UDMA/PIO mode, RAID configuration, CPU speed, RAM size and the quality of drivers.

DiskTT simply tries to give you an indication of the amount of Megabytes per second read and write speed you get under your normal Windows 9x/ME/NT/2000/XP environment.

What's New in This Release: [ read full changelog ]

· New: selection of file caching options. In version 1 lots of people were testing
· their disks with file sizes that were less than the available RAM resulting in very high read thruput. In that particular situation the file is completely cached by windows in the first write action. After that the read tests are fully read from the file cache (eg RAM). You are then in fact measuring the speed of the internal memory through file I/O routines in stead of the harddisk.
· New: when an action is aborted (keyboard stroke or mouseclick) the results measured
· thus far are shown in a hint.
· Changed: set test file size from 10MB up to 100GB.
· Changed: set chunk size from 1KB up to 10MB (in KB).
