What type of Desktop Hard Drive Your Computer Needs!

It’s quite complicated for the people to figure out what sort of desktop hard drive will be suitable for their system to install in.

Installing a correct desktop hard drive in your system can improve its workability and performance instantly. A lesser disk space in your computer irritates you while performing your tasks quickly and it also dissatisfies when you are in need for playing games, frequent web surfing, freelance working and watching movies etc.

What is Interface?

There are usually two types of users, one who use the old system and the other use the advanced machines. Both types of technicalities are mentioned below.

1. ATA/IDE/PATA - 40-Pin Connector - For Old Systems

2. SATA (Serial-ATA) - For New Systems


First of all, the users need to have an understanding that the first hard drive interface is basically the IDE/ATA/PATA interface. The confusing part is that the same type of technologyis being referred by all these three terms for the users who just have started researching about the hard drives. The information provided below describes the full terminology for each of the three names.

All the three terms for this hard drive interface defined above contain certain values and references for the technology being used. To clarify it further, the guidance provided will insinuate to the interface via its IDE term.

Assimilation of the controller into the hard drive is signified by the Integrated Drive Electronics (IDE). Connecting hard drives with motherboards, this interface engages a 16-bit connection in similar tendency. Interfaces of Enhanced Integrated Drive Electronics (EIDE) work faster and comprehensively manage hard drives, having over 50GB storage as compared to the hard drives assisted by this interface of no more than 540MB. The matter of fact is the EIDE editions incorporated with the IDE technology are usually more costly than the outdated IDE. The cable lengths longer than 18 inches or 46cm are also not supported by the IDE interface.


(SATA) The Serial Advanced Technology Attachment interface is more advanced and latest technology than the IDE interface and it is also called Serial ATA. A desktop computer can be operated better with SATA, its cables are thinner and longer and provide airflow sufficiently. It integrates less pins and that produces minimum issues with electromagnetic interference. Hard drives having such type of interface are usually more noiseless than their IDE counterparts.

Furthermore, limited data transfer speeds and bandwidth are featured with IDE and EIDE. SATA comes with the speed of up to 1.5GB per second. The latest SATA 2.5 interface eventually provides higher speed that reaches to 3GB per second. The Native Command Queuing (NCQ) has also been incorporated with the 2.5 SATA devices, it helps hard drive systematize the read and write instructions that are sent to it and then initialize which ones will be carried out first. Comparatively the SATA interface provides longer cable advantage that goes up to 1 meter and on the other end IDE’s are manufactured with only 40 cm cable limit. The most interesting feature that comes with SATA is ‘hot swapping’, through that you can simply replace out devices within the computer while it is running.

First of all, identify your system’s interface that you are using from the above mentioned points whether you are a user with availability of old system or an advanced one. Once you have identified your system’s interface then try out to declare your working capacity, it would confirm you the required speed for your usage.

What Capacity do I have?

The same term goes here, there are commonly two kinds of users, the one who has a wide range for usage that includes downloading digital movies, music, software and playing games etc. The second type of user is the one who intends to use the system mostly for official purpose like online working or freelancing. The required capacity for both the users is mentioned below for a technical reference.

1. Movies, Music, Games - 1TB and more

2. Web Surfer, Freelancer - Less than 500GB

What Speed do I need?

The speed relates with both the points mentioned above, it totally depends on your usage and your system’s configuration. If you have a broader cycle of usage, you intend to use the system for entertainment purpose which includes the factors mentioned above then you need to have an upgraded version for your system and a definite need of high speed hard drive. If you fall in the next category mentioned above having normal usage most often for official requirement, you need a low-noise and low-profile hard drive that is energy saving at the same time easy on your budget. The approximate speed is mentioned below for both types of user, it will help you getting optimum performance out of your system.

1. Movies, Music, Games - 7200RPM OR 10000RPM (Maximum)

2. Web Surfer, Freelancer - 5400RPM
