What are the features you should look out for?

Drive Size

This is a very subject topic. It depends on what you need to do. If you simply need to transfer a limited number of files then a smaller drive would suffice. But if you want to back up your entire computer and several other computers or you want to use it as a storage for large amounts of video and audio files then you will want a larger Hard Drive size. New models range from several hundred GB (gigabytes) to several TB (Terabytes). Year by year storage sizes has been increasing with new and improved technology.

Drive Speed

The spin speed or RPM (rotation per minute) is what you need to pay attention to. The faster a disk spins, the faster your computer will process and find what you are looking for. So, a 7,200 RPM hard drive would be faster than a 5,400 RPM hard drive. However, you will rarely find any difference between the two unless you are working with large files and applications.


The recent trend is that SSD (solid-state drives) are replacing HDD (hard disk drives) due to the high-performance capacity of SSD. It gives faster access times and lower latency. Although SSD is becoming popular the HHD is still used more due to the higher cost of SSD and the faster speed of SSD might not be needed by many. However, more devices are starting to be shipped with SSD instead of HDD as it is more reliable and stable especially for laptops.


The way a Hard Drive interacts with a processor has undergone several changes over the years. Each new change has drastically improved the transfer speeds and ease at which the motherboard handles the drive. The current standard interface is SATA (serial advanced technology attachment).


You will notice that there is a wide range of hard drive prices for devices and it is very hard to tell them apart. So, it’s up to you to decide which factors are most relevant to you.

There is one way to determine value which is to divide the drive’s price by its storage capacity to get its price-per-gigabyte.
