Whichever technology of SSD you choose it is important to note that one can't just drop in a SSD in place of a HDD. Even at 100,000 write cycles rating the SSD will be 'used up' in very short order (months in many cases) if the common (and default) Windows practice of using the disk for the Windows swap file is not disabled. This usually necessitates providing enough extra RAM to either provide space for a virtual drive or to make swap file use unnecessary. There is a place for SSDs in industrial applications, expecially where hard service like vibration kills HDDs quickly, but like any other component they must be applied sensibly and with regard to their limitations. Also, the comments on expected lifetimes of HDDs are interesting. It seems that as HDDs grew in capacity they aslo declined in longevity. We have some machines in the field using old 10 and 20Gb HDDs in datalogging operation with continuous use 24 hours a day that are over 20 years old. Now with new HDDs we recommend that customers plan on replacing them least every 5 years to avoid unexpected system failures, and sometimes they don't last even that long. It seems that PC components, even those used in 'industrial' computers are built for the disposable desktop market where the norm seems to be to replace the PC every few years. There is a definite but admittedly small market in industrial applications for smaller HDDs (or SSDs) with manufacturers' lifetime ratings meaasured in decades of continuous use instead of yesrs .
