Real-time SMART drive monitoring, so for instance you can see the current temperature of any SMART-compatible drives. Low-level Windows data like volume GUID names. There are specific reports on your USB and SCSI drives. And live file system statistics, so you can see which drives are being accessed the most. There's geometry data (the number of cylinders, tracks, sectors and more).
Like pointers to your various drive types, manufacturers, serial numbers and controllers.
What you actually get is much, much more. To take an example, when you launch the program you'll see a button called Volumes, and so you might think this would lead to a screen that lists your PCs drives, their free space and so on. SIV is an extremely comprehensive system information tool that tells you everything you could ever want to know about your PC.
