One disk drive strategy is to get a small 128 MB SSD that only holds Windows 7

One disk drive strategy is to get a small 128 MB SSD that only holds Windows 7 and the application programs and place the remaining data on another larger SATA drive. The Windows supports the Windows paging files and temporary file area. These areas are constantly used by Windows to store and retrieve data while you are working on the computer. Making that storage and retrieval process faster makes Windows more responsive. Word, Excel, Pictures and Music files stored on another slower drive do not make the Windows 7 computer less responsive because we expect some delay every time we retrieve one of those files. My computer uses a 128 GB SSD for Windows. It has a Windows experience Index of 6.8. All my Windows 7 Serial data is stored on 1TB SATA drives with a Windows Experience of 5.9. I have not tested 10,000 rpm drives as yet to determine their Windows Experience Index. The Windows Experience Index is not published for any drives because it depends in part on the motherboard and CPU to which the drive is attached.

We must also bear in mind that, not being validated software, there are Microsoft Windows 7 Key many supplements that are not going Windows 7 Product Key to install or upgrade and in the case of Windows pirates who allow these discharges, sometimes not Win 7 Ultimate Key properly installed, causing even more problems.
