Tim out in Washington state wanted to know the best drive choice for his PCs OS. SSD or a 10,000 or 15,000 RPM hard drive. First off future proofing in the PC world is a bit fools game. Technology changes so fast that you’ll be upgrading in 3 -5 years regardless of what you have installed. Now in terms of longevity SSDs are relatively new devices with little long term experience compared to traditional hard drives. However, SSDs offer incredible performance with low heat, low noise, and no moving parts.
