This is ridiculously fast.  I was upgrading to Window 8.1 and decided might as well update my hard-drive with the SSD over the decent 7,200rpm disc hard-drive.  Well Window 8.1 installed in around 10 minutes compare to like aalmost an hour.  Boot time i sa few second, faster then my tablet.  I also have another sony vaio laptop with a ssd, this one is faster then that one by a little (this one has a faster processor too). 

Question: How is the speed of the thing?
Answer: 7,200rpm
