SiSoftware Sandra is an information & diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software, and other devices whether hardware or software. It provides similar level of information to Norton SI, Quarterdeck WinProbe/Manifest, etc. The Win32 version is 32-bit and comes in both ANSI and native Unicode formats. The Win64 version is 64-bit and comes in native Unicode format.

Useless application. Provides incorrect (partially) information about your PC.

Needlessly complex for benchmarking. Annoying interface for same. All that installation crap should not be necessary either. Plus, it's extremely slow when you do execute the benchmarking sequence.
This feels like a very disjointed effort. It's an uneven patchwork.
Not a fan.

I only remember Sandra from a few years back. As I recall, it was quite a powerful set of utilities and my boss (yes, he had a paid license) used it to burn in every PC he built (installed then uninstalled of course). Yes, $35 plus is a lot of money for burnin software, but if it's as good as it was back then, it worth it if you make a living at evaluating and building PCs. No longer in the PC repair business (do some contract work now but it's more grunt PC related then repair) so things may have changed since 2010, but I'm pretty sure Sandra is still a good set of utilities but may be, as others have already mentioned, a little heavy for most folks use, but if you want a thorough test, it'll meet your requirements for sure. :)

A bit big for what it does & not cheap, try HW Info instead.
