The Best & Fastest Internal Hard Disk Drive (HDD) Brands | 2015

Mechanical hard disk drives (HDD) have remarkably evolved in the past few years to become a more reliable and sustainable solution for most types of users, ranging from mainstream-class level up to enterprise. With the new technologies implemented in their manufacture they could successfully work around many reliability issues their former generations went through, most significant is speed and stability. As far as speed is concerned, the biggest portion of the focus and efforts of hard drive manufacturers is directed to internal storage space. That’s why, as of the time of writing these words, the best and fastest hard drive solutions out there are just internal drives and are released in 3.5-inch form factor (i.e. Desktop Hard Drives).

Important Notes:

• If you’re looking for the fastest hard drive no matter how much it costs, we strongly recommend you to obtain a solid-state drive (SSD) instead.

• if you aim by seeking the best internal hard drive to use it as an external storage solution, we would highly recommend that before you continue reading this article to first view our best & fastest external hard drive list, where we gather the most reliable branded drives there.

The Fastest Hard Drives (HDD) Only

High Speed
There’s a consensus among IT professionals that the main culprit for the slowness modern computers undergo is the primary storage device, represented often by a mechanical hard drive. As a computer technician myself, I’ve found that most of the sufferings computer users experience come from their slow hard drives, and seeking the fastest internal hard drive as a replacement for your current drive is a very wise step to take. Because usually there is no complaint against processor speed, and the graphics card performance is impressive, and the only thing that gets on nerves is the slow responsiveness of the computer, especially when you try to store/transfer huge files, load resource-demanding games, launch heavy applications, or even just try to boot-up a machine with an operating system stuffed with many applications. These all justify finding a speedy solution to cut down on the time wasted in waiting.

Capacity That Matters

Desktop PC sales might be down, but our storage needs are increasing at a rather fast pace. When building a PC many experts often tell people to find out how much storage space they need now, then double that number for growth and then double that number again as you don’t know what the future holds. Hard drive manufactures likely love that advice, but in all honesty it’s not a bad way to ensure that you don’t run out of space. So, if you have 1TB of data on your PC now, you might as well look at 3TB, 4TB or even 6TB hard drives for your next system build or secondary storage drive.

A Fast Hard Drive (HDD) Or An SSD?

I have written this article assuming that you are already aware of the existence of the flash-based solid state drive (SSD), which is undoubtedly a much faster and a more reliable solution than any spinning platter-based hard drive available. [Check out our fastest SSD list.] Yes, there are still strong and valid reasons for picking up a traditional hard drive instead of an SSD, mainly capacity and price, as the SSDs that are being used in desktops today do not have the capacity to store the tremendous amount of media we all use and store today. So a hard disk drive is still necessary because it provides a much larger storage capacity and just as importantly, affordably so. But I have been always recommending obtaining them both in a combination where the SSD takes care of the operating system and user’s favorite files and applications, while the hard drive is dedicated to backup, file transfer and storage. [Read if you wish: “The Best To Do: Get an SSD and Keep Your HDD“]. That’s if you want to build a new rig and can afford the expenses of both, otherwise you can still find in premium hard drives what meets most of your requirements.

That being said, obtaining the fastest internal hard drive can be a good idea if your budget is limited and you only want a single drive for your machine for all purposes.

But stop here, does “fastest” necessarily mean “best”?

Actually not, because reliability (with which we gauge “best”) has a few factors and speed is one of them. A hard drive may be very fast, yet suffers from failure and instability, which makes it a real bad choice. On the other hand, a stable hard drive may be slow and will waste lots of your time. That’s why; the best hard drive must feature the highest speed and longest stability. [For more details on these factors, you may want to read: Performance characteristics of a good hard disk]

The Most Reliable Internal Hard Drive Manufacturers

If your priority in internal hard drives is quality, your choices will narrow down to the drives released by three most prominent high-authority manufacturers; HGST (aka Hitachi GST), Seagate and Western Digital. These manufacturers are well-known to produce the most reliable hard drives.

As for Toshiba, it’s a great manufacturer when it comes to external hard drive segment, but it’s notorious in the internal hard drive industry due to the high failure rate their drives suffered in the past. Add to that, although Toshiba claimed the improvement in the reliability of their new drives, we couldn’t find a real-world testing report released by a trustworthy IT professional regarding this manufacturer’s internal hard drives, therefore we have decided to omit its drives from our list.

In the past there were many hard drive manufacturers that compete with these three guys, such as Maxtor and Samsung, but all of them vanished and left the industry. For more information about the defunct hard drive manufacturers, visit this page.

In May 2012, HGST was totally owned by Western Digital, and the announcement of that is published on WD’s official website here.Therefore any drive found in the market stamped with the old traditional HGST trademark is produced before that date, and we are unlikely to present these drives in our list, as we only include the latest produced hard drives with the newest technology. Just make sure your HGST drive has this new trademark:

This trademark indicates that the hard drive models formerly produced by HGST are being now under the development of Western Digital, this is to distinguish them from other hard drive lines originally manufactured by WD.

So now your choices of 2015 are confined between two manufacturers: Seagate and Western Digital.

What Do You Need From an Internal Hard Disk Drive (HDD)

Before taking the decision of purchase and going for any internal hard disk drive (hdd) listed below, you have to gauge your needs first and see what type of user you are and for what purpose you want a new hard drive.

If you are an extreme gamer or a professional video editor who use high-end and complex programs that consume lots of the system resources, and for that reason you need a strong and very reliable hard drive, I suggest you go for Seagate Enterprise Capacity V4 or Western Digital Black Improved Version. They offer unparalleled performance and outstanding reliability, and they come with 5-year limited warranty.

Or you can go for a regular hard drive [see below] as a secondary storage, and use a solid-state drive (SSD) as the main boot drive, and connect them both in hybrid mode [Read: Do It Yourself: Combine SSD With HDD In Hybrid Mode]. That way you will guarantee high speed and large capacity for a reasonable price.

Regular User
If you are just a regular computer user who don’t have any professional, heavy resource-demanding application to often work with, particularly high-end video games that consume lots of system resources, or a complex graphics design/video editing software, then a regular/mainstream hard drive must be pretty much sufficient.

In terms of performance, I suggest for this type of users to go with Seagate Barracuda Internal Hard Drive. It offers a very good performance for the price and with a 2-year limited warranty. It’s top-notch version comes in 6TB capacity, so this is supposed to be the best deal if you look for a combination of capacity and performance.

If your main concern is capacity, and you need a hard drive mainly for backup and storage purposes with a very decent price, and performance, although important, comes second in your priorities, then I strongly suggest you to consider Western Digital Green Desktop Hard Drive. We have not included it in our list because it spins at 5400RPM, and that’s below our minimum standards in determining the best hard drives.

How Did We Make Our Recommendations?

Our factors in determining the best internal hard drive are: Speed, stability and endurance, and they all form the word “reliability”. Speed and stability both feature “performance”, while endurance features “longevity”. We base our verdicts mainly on IT professionals’ reviews of each item listed below, alongside with the users’ ratings. That way we make sure that these drives are the top-notch of their class based on our standards of determining reliability.

You’ve to note though that only if you see the testimonials of IT professionals quoted in the details page of a particular drive, it means we considered the IT professionals’ reviews when choosing that drive. Otherwise we would just depend on users’ ratings on

The Seagate Enterprise Class 3.5 HDD V4 6TB is an exceptional performer, shaming all the 7200 RPM drives that preceded it. According to and others, this drive in its 6TB capacity is currently the fastest drive in the world. [Read their testimonial below in the testimonial section]

Hot Hardware:

The Seagate drive’s average read/write speed of 164MB/s is the fastest we’ve ever seen from a drive with rotating platters, even besting the former champ, WD’s 10krpm Velociraptor by a hair. The fact that the Seagate drive is faster despite its slower rotational speed shows you just how much of an advantage areal density can be.

Tweak Town:
The Seagate Enterprise Capacity 3.5 HDD v4 delivers a big jump in density, impressive performance gains, and even increased power efficiency. With its five-year warranty, class-leading performance, and host of enterprise class features, it earns the TweakTown Editor’s Choice Award.

Overclockers Club:

Well, I think it is safe to say that the Seagate Enterprise Capacity 6TB 3.5 HDD v4 is indeed a BEAST. I think I’ve said “beast” quite enough times throughout the review, often more referring to the size of this drive, but along with its large capacity is some rather large and impressive numbers to go with it.



If you find this drive expensive and you cannot afford its price, consider the following hard drive. although its first release date is in October 2013, it still performs great according to today’s standards, and with adequate price compared with the above.
