Simple System Info - The One Liner - Powershell

This Powershell script boils down essential system information into 1 line for a post, quote or tweet. 

Example outputs; 

  1. Microsoft Windows 10 Pro 1803 (10.0.17134.81), Intel Core i7-2760QM CPU @ 2.40GHz * 4, 32GB RAM, 1TB HD @ 7,158 RPM
  2. THINKPADW530 [42763JZ], Microsoft Windows 10 Pro 1803 (10.0.17134.81), Intel Core i7-2760QM CPU @ 2.40GHz * 4, 32GB RAM, 1TB HD @ 7,158 RPM
  3. Microsoft Windows 10 Pro 1803 (10.0.17134.191), Intel Core i7-4600U CPU @ 2.10GHz * 2, 8GB RAM, 128GB SSD

No more cobbling this together, let's adopt a universal standard. 

Bonus: Detects SSD size and HD RPMs.

.SYNOPSIS
   Detects if the passed Physical Disk Id is a Solid State Disk (SSD) or a
   spindle disk. Returns true for an SSD and false for anything else.

.DESCRIPTION
   Use Get-PhysicalDisk to get the Physical Disk Ids for the system you wish
   to test. This script supports values being passed throught the pipeline.
   
   The methods used for detecting are by reading the Nominal Media Rotation
   Rate and Seek Penalty. These values are measured through method calls
   into the Kernel32.dll. If either of the Win32 DLL calls return true then
   the script will return false. If an exception occurs in either of the
   Win32 DLL calls, the return value will be dependant on the remaining call.

.PARAMETER PhysicalDiskId
    The LUN based physical disk id.

.EXAMPLE
   Get-PhysicalDisk | Select-Object -ExpandProperty DeviceId | Test-SSD

   This example will test all the disks on the local computer.

.EXAMPLE
   if (Test-SSD -PhysicalDiskId 0) { $delay = 0 }

   This example will change the delay variable on a script if the
   first physical disk is an SSD.
