I have a Seagate 2tb spindle hdd a bit under 2 years old. It was noisier than expected from the start, but performed fine. Now, not quite 2y later, there is slow performance in real world as well as very poor crystaldiskmark results vs a much older Seagate 2tb. The newer one is a lower profile (thinner) drive than the old. Both 3.5" so otherwise very similar drives. I am wondering if there is anything on the software side that could cause 2 drives to perform so differently, or if I should return this drive under warranty, if this sounds like a dodgy drive. I never thought of the sounds it makes as a problem, but it's noticeably louder than the old drive and most other I've had. Crystaldiskmark results are attached. Test was default setting, hitting "All" button. D: is the newer drive. Z: the older (about 5y maybe more)
