I recently purchased an ASUS G75 from Best Buy and I'm preparing to upgrade the primary drive to an SSD drive. I have an older 500GB 7200rpm drive, which is about 2 years old and I have the original 1TB 5400rpm drive that came with the ASUS.
The problem I'm having is that the 500GB 7200rpm drive "SHOULD" be much faster...but it's about 50% slower. I looked at the specs for each drive and the 7200rpm drive is also Sata 3.0GB, 16MB cache vs 8MB on the 5400rpm drive, and obviously a faster speed...so why is it slower?
