We clicked the Graph button on the Function menu, which opened an interesting feature that creates graphs displaying disk information via a tool called Flot. Clicking a small arrow in the corner of these entries called up that drive's information in the main view. A ribbon along the top of the interface displayed all our system's disk drives with their color-coded status, temperature, and drive letter. A large, color-coded Health Status display indicated our PC's health was Good, while a similar window below it displayed the drive's temperature in Celsius, the cool blue color indicating at a glance that all was well.

It displays a lot of information, including SMART data for compatible disks, firmware version, RPM, power on count and hours, and even advanced options such as Automatic Acoustic Management/Advanced Power Management (AAM/APM) settings.Ĭrystal Disk Info's properties-like interface opened with our selected drive's name, model number, and capacity in gigabytes prominently displayed. Crystal Disk Info Portable is a fully portable version of a compact, free disk information utility.
