One day I decided to check out this utility called Slimdriver that scans your PC to make sure it has up to date drivers. It offered to download and install 'Intel Rapid Storage Technology' driver which I have never been offered by Windows update. Here is what is says about this driver, "Intel® Rapid Storage Technology offers greater levels of performance, responsiveness, and expandability than ever before. Whether you are using one or multiple serial ATA (SATA) or PCIe drives, you can take advantage of enhanced performance and lower power consumption from the latest storage technologies. Additionally, you can rest easy knowing you have added protection against data loss in the event of a hard drive failure." I've never used this driver in the past and it has a long startup delay so am wondering if it is good to have or not really necessary.
