The best 40GB hard drives come from brands like IBM, Axiom Memory, Kingston, Western Digital and Hitachi. SATA and IDE/EIDE are the interfaces used to transfer data between computer and these hard drives.

You can pick a 40GB hard drive for your laptop or desktop according to the form factors which are 2.5 inch and 3.5 inch respectively. This much capacity is sufficient to store small amount of important data but not for saving large files of your arts and graphical work.

Faster access to data depends on the spindle speed of these hard drives. It is advisable to go for a 7200RPM hard drive for better performance. Caching would also contribute to the hard drive performance so you should go for at least 8MB of buffer size.

You can get a warranty period up to three years on buying 40GB hard drives. The list below shows the best 40 GB hard drives of 2013.

    Frankly speaking, it is not easy to name the winner of this test session, but the second-generation Intel X25-M deserves this title more than anyone else.

Being somewhat inferior to its predecessor at writing very small random-address data blocks, the new X25-M delivers excellent and very stable results under server loads.
