Sound Card: Gigabyte on board sound generator Memory: Corsair Vengenance DDR4 16gb (2 DIMM) System Manufacturer/Model Number: MFG by ME They are fine for the capacity of 250gb vs a 750gb.īottom line is that lower capacity and slower speed drives cost much less then the higher speed/capacity drives. This also applies to platters/media of lower capacity which are the same as those used in higher capacity drives, but contain more defects. However platters that can't be used for 7200 drives could be used in slower drives. Since all platters are not created equal there are fewer of them which raises the price. They cost more because they have to fly the heads closer to the media which requires a Platter surface to be smoother and less defects. The same reason applies to 7200rpm vs slower drives. The yield of platters/media for larger capacity are fewer and thus will cost more. Since the 2.5' is quite smaller physically vs the 3.5' drives, the media needs to be more perfect for 2.5' drives vs 3.5'. Media of all types and sizes are never perfect ie they all have defects/bad tracks and some more that others.

The cost difference is primarily caused by the media.
