Ok, I just defrag last night. What a difference it made in performance. Windows popped up really fast. I've been noticing a trend that my hard drive need to be defragged at least once every 2-3 weeks. I ran the analyzer button and it said that the volume need to be defragmented.
Also, we're getting a new hybrid hard drive in 2006 did you guys here? Samsung and Microsoft join partnership to create a new kind of hard drive that uses a 1GB OneNAND flash chip inside it, which will serve as a write buffer and as a solid-state boot disk for Windows.
The process is like this: The act of writing data to the hard disk, such as user files or cached images while web browsing, would instead be intercepted by the hard disk. Only when the flash memory's "write buffer" was full would the hard disk be spun up, minimizing the time and power that would be spent keeping the drive's rotating media spinning.
