How to Choose a Hard Drive for a Computer or Laptop


The arduous drive is the most well-liked storage machine right now. Its predominant benefits over opponents are giant capability and low worth. Even although quick SSDs are on the rise, they’re nonetheless too costly for excessive volumes. Therefore, it’s too early to write off conventional arduous drives. Here is what you need to listen to when selecting them.

Does the producer matter?

Previously, info was not so accessible, and gadget manufacturing applied sciences may fluctuate enormously from firm to firm. In the fashionable world, manufacturers compete intently with one another and produce merchandise which can be comparable in parameters. Therefore, in our opinion, it’s not so essential which producer you select: Seagate, WD, or Toshiba. 

Seagate stays some of the well-liked HDD producers. Almost all of their present fashions have a median buyer score of 4.5 factors.

Form issue

There are a few choices right here – 2.5 and three.5 inches. Laptop homeowners merely haven’t any alternative: as a rule, solely 2.5-inch arduous drives are appropriate for laptops. In idea, you possibly can set up any on a PC, however once more, most frequently these arduous drives are 3.5 inches. If solely as a result of, when it comes to a unit of reminiscence, they normally value lower than 2.5-inch ones. 


Almost all fashionable HDDs have a SATA interface. The solely distinction is within the launch model. There are solely three of them, 1.5, 3, and 6 Gb/s. Versions are backward suitable. That is, a SATA 6 Gb/s arduous drive can work in units for all different releases, however not vice versa. As you may guess, the throughput of the disk relies on the discharge. If your motherboard helps SATA 6 Gb/s, you possibly can ignore all of the others. And to discover them in our time, frankly, is kind of problematic. 


Perhaps it’s from this parameter that you need to construct on. 500 GB and 1 TB drives are appropriate primarily for workplace computer systems. If you might be an energetic person who commonly downloads films and installs video games, we might advocate paying consideration to fashions with a capability of two TB or extra. Why not 1? It’s easy: some fashionable AAA video games take up 200-250 GB. 4 video games, and the arduous drive is full. 

In the present realities, the development of accelerating arduous drive house won’t disappear and can solely speed up within the coming years. Graphics are getting higher. Resolutions are getting increased. Game worlds are getting larger. Hence it seems that a terabyte is eaten up by simply a couple of tasks.

When it comes to information storage (for instance, backups or archives {of professional} pictures and movies), take an HDD of at the very least 4 TB. Options from 6 TB are nonetheless costly (when it comes to 1 TB of reminiscence).selecting the best hard drive

Spindle pace

This is the primary parameter that impacts the pace of the arduous drive to the utmost extent. Today, there are two predominant varieties of HDD: with a spindle pace of 5400 and 7200 rpm. There are fashions with up to 15,000 rpm, however they’re very costly and uncommon. 

We advocate 7200 rpm drives as a result of they’re on common 1.5 occasions quicker than 5400 rpm. However, 5400 rpm is best for a laptop computer as a result of it generates much less warmth and fewer vibration. In addition, low-speed HDDs are thought-about extra dependable due to much less put on and tear on parts.


It appears that every one arduous drives are the identical. That is, they’re appropriate for writing any information. But there are additionally specialised options – specifically, for use in video surveillance programs, servers, RAID arrays. How are they totally different from “regular” arduous drives? Preparedness for particular working circumstances. For instance, HDDs for video surveillance are designed for round the clock operation with fixed load. As a rule, they’re extra dependable and last more.

Cache dimension

Many customers suppose that the pace of the arduous drive relies upon solely on the dimensions of the first stage cache, however this isn’t so. Speed ​​indicators are the cumulative results of many parameters. The cache is simply a small partition with a excessive information switch charge. Yes, it actually hastens the HDD, however solely barely and never in all operations.

Therefore, you shouldn’t concentrate on the quantity of cache within the first place. In basic, the extra the higher, however generally the dimensions of the cache relies on the dimensions of the arduous drive. And additionally, an essential function is performed by software program optimization, details about which is sort of unattainable to discover. Often, HDDs with a giant buffer are server options, which, on the similar time, can lose to comparable fashions when it comes to pace and a priori value greater than them.

What different choices?

Those who don’t want to put up with the low pace of arduous drives in contrast to SSDs can have a look at hybrid drives (SSHD), which mix applied sciences for storing information on a arduous drive and NAND reminiscence. Such options are costlier than traditional HDDs however considerably outperform them when it comes to pace.

In some circumstances, not an inner however an exterior HDD could also be helpful. This can be utilized as backup storage: join if mandatory and retailer at the very least in one other room.
