10 Best Internal Hard Disk in India | Buyer guide and review

If you’re looking to supersize your storage, then upgrade your PC or NAS drive with our pick of the best high-capacity HDDs

The ever-decreasing price of SSDs means that traditional hard disks are less universal than they once were. However, as media libraries grow larger, and 4K video becomes commonplace, there’s still very much a role for affordable, high-capacity storage.

The question is, which hard drive should you buy? Does performance matter, or should you just go for the cheapest model? Here’s our verdict on the five major hard disk models from the two industry giants (namely Western Digital and Seagate).

How to buy the best hard disk for you

Should I buy an HDD or an SSD?

Nowadays, if you’re buying a hard disk it’s most likely as secondary storage for a desktop system. Under all circumstances we’d recommend using an SSD as your system drive: the performance difference is simply too good to miss out on.

What if you’re using a laptop, or a compact PC that only has space for one drive? In that case, your best bet is to equip it with the largest SSD you can afford. Or, go with a modest solid-state system drive and use an external hard disk, NAS drive or cloud storage for your personal files. In this feature we’ll focus mostly on high-capacity 3.5in desktop drives.

How many terabytes do I need?

A terabyte is a hell of a lot of storage – it’s enough to store around 285,000 songs in MP3 format, or around three million Word documents. There’s a good chance that if you tot up all the files on your computer, and tucked away in various cloud storage services, they’ll come to much less than a terabyte.

That doesn’t mean you’ll never need more, however. Big collections of digital photos and media libraries are eating up space, especially with the rise of 4K video – and as working from home becomes more popular you might end up with big document archives to look after as well. You might also want to keep backups of your downloaded installers, now that games and applications no longer come on physical media.

So it makes sense to give yourself plenty of headroom, and make sure that you won’t have to go through the hassle of expanding your storage again in a year or two. As a rough guide we’d suggest that 2TB ought to be enough to cover modest storage needs for the foreseeable future: more hardcore users should consider going up to 4TB.

It’s very hard to determine a single best top pick amongst all internal laptop and desktop hard drives, because of their vast diversity. Some of them are manufactured for NAS, some for backup or surveillance systems. For more options, go to our separate best internal hard drive top list, or check out the fastest internal HDD list for the best-performing consumer hard drives currently available.

To find the best internal hard drive, you definitely must know where you will put it and use it, which is why we built our list from what we consider to be the best 2.5-inch and 3.5-inch drives for various uses. We focused on the fastest and most reasonably priced drives for each category, so most drives on this list are 7200RPM hard drives. You’ll find all of the important specifications for all hard drives on our top list, as well as an explanation for all of those specs after the list.

How we picked the best HDDs

Customer reviews on major retailer sites represent reliability via real-life user experience rather than just numbers provided by the manufacturer. This was the first step in picking the best internal hard drives for our list as all other characteristics become irrelevant if the drive breaks a day after its warranty ends.

We also looked at Backblaze data and other similar sources to determine the most reliable brands and drives. Cloud backup companies can offer a massive amount of hard drive reliability data because they have thousands of hard drives running non-stop all the time.

We looked at various benchmarks from users and other reviewers, but our main focus was UserBenchmarks. Their benchmark results, aggregated from hundreds if not thousands of users, are more objective than separate speed measurements, and they also give us a unified platform on which to compare the drives to one another. A thing worth noting is that UserBenchmarks’ results are usually lower than those of separate benchmarks.

​Sequential read/write speeds of fastest capacity model in series

Internal hard drive performance

The speed of HDD data transfer is one of the most important factors you need to look at before buying a hard drive. Capacity is displayed upfront and you can at least roughly tell how much you’ll need but transfer speeds and even spindle speeds often remain as under-the-hood characteristics. Regardless, to improve the overall performance of your PC/laptop, you need a fast hard drive, since your whole system is almost always as slow as its slowest component and that component is often times the hard drive.

But what exactly do we mean by speed and how does it affect how fast a computer is? Well, there are two main speeds that can be attributed to HDDs, them being spindle speed and data read/write speed.

Hard drive spindle speed, 5400RPM, vs 7200RPM

This is the most basic core characteristic of a hard drive’s performance. It describes how many Revolutions Per Second (RPM) the drive’s platters can achieve. This correlates to how quickly the mechanical parts (drive platters and read/write needle) can interact to locate the data you want to read and how quickly data will be written on the drive platters (more on that later).

The two most widespread spindle speed standards are 5400RPM and 7200RPM, both of which have a respective data transfer speed range you can expect from such a drive. You can find various other standards, like 5900RPM and 10000RPM but these are much rarer than the previous two. The price difference between the two spindle speeds is much smaller than the RPM difference – you can expect to pay $10-20 on average more for a 7200RPM drive than a regular 5400RPM one.

Because of technical reasons, like aerodynamics, centrifugal forces, etc. faster spinning drives can hold fewer platters, so finding 2.5-inch 7200RPM drives with higher capacities is more difficult than finding 3.5-inch ones. What might also concern you is the extra energy needed to spin the platters at higher speeds, meaning 7200RPM drives will always use more energy than 5400RPM drives, and will more likely than not be a bit noisier. However, the extra energy usage might add less than a dollar to your yearly energy bill, so whether this is an important enough trade-off is up to you to decide.

Hard drive data transfer speed

This is the much more complicated performance metric of a hard drive that depends on many smaller and larger factors. Data transfer speeds or read/write speeds represent the amount of data that a hard drive can deliver to the computer via its interface. These speeds are usually measured in megabytes per second (MB/s), not to be confused with megabits per second (Mb/s, Mbps). Both values represent data speeds, however, 1 byte = 8 bits, so the same measurement in megabits will result in an 8-times larger number (like the math between inches and feet).

In a magnetic hard disk drive, a read/write needle has to seek out the place on the drive’s platters where data has to be either read from or can be written to. The read/written data is sent to/from the computer through the drive’s controller, which decodes signals from both sides so that the HDD and the computer can “understand each other”. The seeking, decoding/encoding, and many other forms of latency add up, making, let’s say, one megabyte of data to be transferred more slowly. The time it takes for it to be transferred can be measured precisely by sending set amounts of data in a controlled manner and measuring how long it takes to transfer them.

You may have heard about sequential and random (4k) read/write speeds being mentioned here and there, but what are they exactly?

Sequential speeds determine how quickly a long, continuous (sequential) string of data can be read/written.

​Random read/write speeds represent how quickly tons of randomly placed, small (usually 4 kilobyte or 4k) files can be read/written.

The difference between the two is huge – sequential speeds are usually measured in hundreds of megabytes, while random speeds of even 7200RPM hard disk drives rarely exceed 5MB/s. This is because moving the mechanical parts between multiple positions is much more time-consuming than having them move in one “line”. Random speeds correlate to loading games or operating systems, where tons of smaller configuration and source files have to be loaded, while sequential speeds are equal to moving large movies or documents to/from the hard drive.

Although the former will likely be the more accurate representation of real-life performance, there are many more minuscule factors that can add up and drastically change this speed between different benchmarks. However, in broad strokes, if a drive has high sequential speeds, it will most likely have fast random access as well. Seeing how random speeds of HDDs are much more difficult to pin down to a certain number, we, as all other reviewers, will focus only on sequential speeds.

As we mentioned before, you can generally expect100-130MB/s from 5400RPM drives and 150-200MB/s from 7200RPM drives, but these values can vary a lot between different computers, different software, and even different units of the same drive. Most of the time manufacturers won’t display any estimates since real-life benchmarks can differ a whole lot from idealized benchmarks. These speeds are often displayed on newer OSs when you paste large amounts of data on a drive but are measured much more precisely and reliably via third-party benchmark software, like CrystalDiskMark.
