I have several Samsung SSDs connected via a SATA cable, and one PCIe SSD drive that is connected directly to the logic board using PCIe slot.

(But keep in mind that a single logical drive, or a volume, INFO: To get drive number from a logical drive letter, check this method: Having done some research and using the info from the answers on this page, here's my implementation using C WinAPIs for Windows 7 and later: //Open drive as such: "\\?\PhysicalDriveX" where X is the drive number In Windows, using C++, is there any way to get whether the main system drive is an SSD or not? I thought that I could somehow generate a large fine (500MB), and then time how long it takes to write the file, but however other system variables can easily influence the result. I've also seen Is there any way of detecting if a drive is a SSD?, but the solution only applies to Linux.
I've seen (v=vs.85).aspx, which is a way of determining if a certain drive is a HDD, CD ROM, DVD ROM, Removable Media, etc, but it STILL can't detect whether the main system drive is an SSD. With HDD, I want my gameserver application to load only the essential objects and entities in each map, with no external objects loaded.With SSD, I want my gameserver application to load each map fully, with all objects in order to maximize performance.I would like to change the performance and behaviour of my C++ application, according to whether the system drive is an SSD or not.
