HDD Buying Tips for Laptop and Desktop

Without a storage device, our computer system is just a dumb terminal who can’t even save or remember any single file or information in it. There are a lot of different kinds of storage devices are available in the market, but HDD still holds the strength to find a place in most of the new computers.

It all about its decent speed which comes with the pretty cheap price tag;

And not just like the SSD, it doesn’t come with the fixed write cycles. But before purchasing any storage device for your computer system, it always important to know every bit about the drive’s characteristics. And of course, take a moment to see who suits you better.

In case if you’re looking for something like 20 times better performance with 20 times or even more higher prices, then HDD isn’t the thing for you and you should need to go for an SSD (Solid-State-Drive).

#So, Lets See How to Buy A Hard Disk Drive:

Buying a perfect hard disk drive for laptop and desktop computers isn’t that simple how it looks like. You’ll need to understand the basics, and your storage needs, and your computer’s needs, and not just that, understanding the performance is the whole another story.

But let me make it easier for you, and get started with the first sub-topic name;

1# – Choosing the drive type

Mainly there are two types of hard disk are available in the market and those are:

  • Internal Hard Disk Drive An internal hard disk drive is the primary storage unit of a computer system, it used in desktops, laptops, Gaming Consoles, Servers, CCTV Cameras and etc. and comes in a variety of sizes just to fit in anywhere you wanted.
  • External Hard Disk Drive – External disk drive is the combination of two different computer hardware which is an Internal HDD and SATA to USB Casing. Which means that you can use any of your OLD HDD as external by using a simple product called HDD Enclosure. But now we don’t need to collect some other 3rd party item just to make our new hard drive portable because most of the manufacturers are making some beautiful drives with some great features like the External WI-FI Hard Drive by WD and a lot more.

It all depends upon you to choose which one. But if you’re willing to buy an external Hard drive for yourself then this article isn’t for you and you should need to check out my this article about: How to Buy an External Hard Disk Drive?

2# – Choosing the right storage size

Hard drive discs not only come in variations of physical sizes but also it differentiates from one another in terms of data it can store. This section discusses the storage size suitable for your system.

Storage size, also called as capacity is denoted through GB/gigabytes or TB/Terabytes. The variations might be possible between the size mentioned in the label and the size as calculated by your operating system.

  • Huge capacity drives: Huge capacity drives also offer better performance. Anything over and above the size of 2 TB is said to be high storage drives. They offer a lower cost per gigabyte and also high data transfer speeds.
  • Low capacity drives: Though they are affordable than the former variety, it comes at the cost of glitches in performance. Less flexibility in operations, lower storage, glitches are the signs of lower capacity drives. The data transfer speed in this storage is lower and also costs high per gigabyte of storage.

The decision between deciding larger or smaller drives has to be made considering the usage. If the usage is said to be high, it calls for the latter HDD drives. A small failure of HDD will cost a lot in terms of loss of files. However smaller drives come at the cost of increased maintenance of multiple discs while compared to larger HDD where a few may serve the purpose.

While using HDD it should be kept in mind that a drive failure might happen unexpectedly. Thus, it is essential to have a backup of all the data to avoid potential loss and stress. And if you are not a collector then having a 1 or 2 Terabytes hard drive is actually enough for every normal user.

If you are looking for a hard drive for a new computer then I think you can compromise the price for the big storage drives and invest that money into the smaller size SSD for your system. In my computer, I’m using a single 256 GB SSD for my active task and used the other single 4TB HDD for my ‘movies, games, and ISOs collection’.

By doing that you can fix the storage bottleneck from your computer because the CPU and Memory won’t do much until you install some fast data access storage. To know more >> Do I need HDD or SDD & What’s The Difference?

3# – Paying for the right performance

Hard disk drive’s performance is the only thing which matters the most because that’s the thing who decides how that hard disk drive will going to perform while processing the data.

Whatever it’s the Operating System or a software install in the OS, everything you use is saved in your computer’s hard drive;

And that’s the reason why the low-performance hard drive is a bad dream of every computer because it can bottleneck the whole performance and not any latest generation desktop or laptop can achieve its full efficiency.

That’s why the hard drive is the third most crucial hardware for the performance after the RAM and CPU.

So, an HDD do need some good figure specification on its box/datasheet in order to perform perfectly. And here are some couple of things what you’ll need to have looked over on the specification’s page for the future hard drive reference:

  • RPM Hard disk is mainly made up of a disk motor with some rewritable disks and the reader or a writer who process all the incoming and outgoing data. The whole performance of a hard drive depends on how fast that motor runs. That’s why there are different RPM motor types HDD available in the market. RMP means round per minute of the disk rotation of a hard drive and if a hard disk’s specification shows 7200 RPM, which means it will be able to run the disk at the speed of 7200 round per minute while processing the data. And make sure you look for the higher RPM number because it’s better.
  • Cache HDD cache or you can say disk buffer both are the same things and mainly use to process current processing data and the only thing what you have to remember is, the higher the cache size is, the higher the performance will be.
  • Speed in MB/s Most of the time you won’t be to find the actual speed of a hard drive on its specification page so you can tell the difference like SSD. And that’s where the benchmark website came in, you can look on the internet and find some HDD benchmark website which can tell you the real-time performance of any popular drive.

4# – Compatibility Check-up

Compatibility is the next big thing while buying an HDD, so make sure don’t forget to read this suggested article about >> Check Hard Disk Drive (HDD) Compatibility with Laptop or Desktop Motherboard

It’s all upon you to buy which one, in case you need some extra help. Here is a list of articles which I update monthly just to make your shopping more worthful;

  1. It is very much important to check for the perfect HDD suitable for the device you are using. if the configuration of the HDD doesn’t match with the configuration of the device, it is going to hamper its performance and will not allow the computer or the laptop to store the data in the HDD.
