The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

GeneralC++ & Thinking about SSD & wear level Pin

I was thinking about the SSD in my wife's laptop. 120GB and it's been running for 4-5 years.

Kind of fell down a rabbit hole...

A Windows App?: Not really
I started looking for apps to tell me the situation.

Found an article that explains some things:
Find out how much longer your SSD will last - CNET[^]

The article mentions this app: Crystal Disk Mark -- not great[^]

All Comes Down to Reads & Writes
Basically the article tells you that most likely it will take you 15 years to wear a good SSD out so don't worry too much.

Found Some Sample Code
Then I found a sample program that makes some API calls and tells you how many bytes you've read and written since the OS was started.

Here's the output for my wife's computer that has been running for over 16 days without rebooting:
http://i.stack.imgur.com/3jTsD.png[^]

Compare those read/write bytes to mine that has only been running[^] for a little over 2 hours.

Here's the code (alterations by me) from c++ - How to get global Windows I/O statistics? - Stack Overflow[^]

NOTE: hard-coded to check only the C:\ drive
Update: Updated method to display the number of days computer has been running.
C++
#include <windows.h>
#include <iostream>
#include <locale>
#include <sysinfoapi.h>

std::__cxx11::string displayValue(LONGLONG);
void getOsRunTime();

int main() { 
    HANDLE dev = CreateFile(LPCSTR("\\\\.\\C:"), 
        FILE_READ_ATTRIBUTES, 
        FILE_SHARE_READ | FILE_SHARE_WRITE, 
        NULL, 
        OPEN_EXISTING, 
        0, 
        NULL);

    DISK_PERFORMANCE disk_info { };
    DWORD bytes;

    if (dev == INVALID_HANDLE_VALUE) {
        std::cerr << "Error opening disk\n";
        return 1;
    }

    if (!DeviceIoControl(dev, 
            IOCTL_DISK_PERFORMANCE, 
            NULL, 
            0, 
            &disk_info, 
            sizeof(disk_info), 
            &bytes, 
            NULL))
    {
        std::cerr << "Failure in DeviceIoControl\n";
        return 1;
    }
    //std::cout << (disk_info.BytesRead.QuadPart).Type() << std::endl;
    //displayValue(disk_info.BytesRead.QuadPart );
    //std::cout.imbue(std::locale(""));
    //std::cout.imbue(std::locale::global(std::locale("")));
    std::cout << "Bytes read: " << displayValue(disk_info.BytesRead.QuadPart) << "\n";
    std::cout << "Bytes written: " << displayValue(disk_info.BytesWritten.QuadPart) << "\n";
    getOsRunTime();
}

std::__cxx11::string displayValue(LONGLONG byteCount){
   auto s = std::to_string(byteCount);
   int n = s.length() - 3;
   while (n > 0) {
      s.insert(n, ",");
      n -= 3;
   }
   return s;
}

void getOsRunTime(){
    ULONGLONG milli = GetTickCount64();
    //3600000 milliseconds in an hour
    long days = milli / (3600000 *24);
    milli = milli - (3600000 *24) * days;
    long hr = milli / 3600000;
    milli = milli - 3600000 * hr;
    //60000 milliseconds in a minute
    long min = milli / 60000;
    milli = milli - 60000 * min;

    //1000 milliseconds in a second
    long sec = milli / 1000;
    milli = milli - 1000 * sec;
    std::cout << "OS has been running " << days << " days " << hr << " hours " << min << " minutes " << sec << " seconds " << milli << " ms." << std::endl;
}
