Hard drives

A hard disk drive, often abbreviated hard drive or HDD, is a magnetic storage device used for storing data. Data is written on the surface of a rotating disk that is coated with magnetic material and magnetized according to the recorded information. One of the main advantages of hard drives is the low price for capacity. The biggest drawback is its mechanism, which is fault-prone and slower than flash memory. Hard drives are ideal for storing or streaming large amounts of data.more

im pretty sure 2.5" form factor is normed and should be identical for all drives except height which can vary but is either 9.5mm or 7mm so yes absolutely it should fit just fine. do you really need the 1Gb capacity? if not might i suggest a 2.5" SSD instead should improve your performance considerably.

Height 0.95cm is equal to the 9.5mm thickness. So yes it should fit with no problem.
But like said before, maybe you could consider a SSD, they are typically 7.5mm thick so should fit with no problem and are silent and a lot faster than HDD ;-)

The search options and descriptions could be better. If I use the filter, I can select 1000-1999 and 3000 and up, but then I do not get the 2000 GB. And I cannot search for thickness. The bigger disks get listed as notebook, but is 1.5 cm thick. And in description, some are listed in mm and others in cm.
The search should cover all range of size in GB and thickness!
