Hard Disk Drives are an important component of any laptop and desktop. This is a permanent data storage where data doesn’t vanish off after switching the device off. The hard disk drives rely on magnetic storage and use one or more rotating discs.

Unlike SSD which have no mechanical part and works like a USB storage. HDDs become famous these days but there are people who still prefer traditional HDDs. Because HDDs can store more data than SSDs (as compare to price ratio) and always work extremely well and you can actually rely on them.

If you are going to buy a new device with an HDD or you are thinking of upgrading your old HDD you should be careful in choosing one. You need to find the good product and don’t take it carelessly as they are one important component. There are various specifications you need to know before buying an HDD.

Firstly, the form factors for HDD basically is the height of the hard disk drive, transfer rate, capacity. So, you need to check the compatibility of your device with a hard disk drive through the height of HDD.

The brand and interface are really crucial as well. Also, the rotational speed, the rotational speed defines the speed of rotation of the disk. So, you should always go for an HDD with more rotational speed. Then next is latency which is how quickly the HDD can read a sector, lower the latency better the HDD.

Also, the data transfer rate and buffer are two important components. One more important component is the storage an HDD provides. Nowadays in the market, there is a hard disk drive which generally offers minimum 500GB storage.

  1. Is there any specific reason why you haven’t included WD blue 4 TB HDD in this list? Is it bad?

    I read the ratings on for this hard disk and to my surprise it’s rated only 3 stars. 30% of people have complained it to have failed on them in just couple of months…. which is honestly not expected from a company like Western Digital whose reputed for making long lasting Hard drives.

    as for Seagate, it has failed on me twice! (7200.11 and 7200.12 both) So I will never buy a Seagate HDD :/

    I am confused. I want the best 4 TB HDD for home usage on my desktop. No NAS or server usage like the ones mentioned above.

    Kindly guide me to the best 4 TB HDD to buy which will last me at least 5-10 years.

  2. You can go for Buffalo Mini-station Extreme NFC which came to the top in 2018 best hard disk. Western Digital My Passport 4 TB this will be the 2nd preference if you like WD. I will always go for WD because it is the best company that give long lasting Hard drives at low range.
