Want to find the best internal hard drive of 2017? Ease your life and check our list of best candidates

Last updated: January 2, 2017

If you are looking for the best internal hard drive, then you have found the answer. I do realize that most of you have very busy schedules and have no time to read long reviews, and that is the reason why we made the list below. Our guide includes hard drives with the best price per GB ratio, combined with speed, warranty, reliability and customer reviews. So you can easily find the best hard drives for your needs, saving a lot of time and money at the same time.

Nowadays it can be very frustrating for a non-expert in hard drives and storage devices to find the best hard drive. After long hours of hard drive tests and research, we determined that the Seagate SSHD is the best hard drive for a laptop on the market, at the moment. It is Solid State Hybrid drive that offers both performance and capacity for a low price. In last years, our need for a bigger storage device is growing rapidly and drives must be much faster and more reliable to manage all that data. Solid State Drives, also known as SSD are the fastest ones, but they are also much more expensive and with lower capacity than mechanical hard discs.

It is very hard to determine top pick from 3.5-inch desktop hard drives, because of their vast diversity. Some of them are manufactured for NAS, some for backup or surveillance systems. To find the best 3.5-inch hard drive, you definitely must know where you will put it and use it. 

How to choose between SSD, SSHD and HDD?

It depends on your situation, purpose, budget and whether you have a Laptop or PC. No doubt, if you have a laptop, you need to look at SSD or SSHD if you don`t want to spend a lot of money then you should buy SSHD. Solid State Hybrid Drives are faster than mechanical hard drives, but they will cost you almost the same money as internal hard disc drives. If you don`t care so much about the money and it`s all about speed, then a Solid State Drive is for you.

For example, 1TB HDD or SSHD drives will cost quite below $100, but the price for a 1TB SSD will be more than $300, that`s a big difference. Also, you need to find out more about your laptop, because if your laptop uses IDE, then you need IDE to SATA. All SSD will work on any laptop that is using an SATA drive connection. On some laptops, you can install both HDD and SSD because they have a place for two drives. Combining both HDD and SSD is the best option to increase performance, capacity and to save as much money as possible. 

Use two drives – SSD and HDD on desktop computer to increase performance and capacity

The same applies if you have a personal computer, then you should combine two types of hard drives – SSD and HDD. You can install your operating system on the SSD and store all your movies, music and pictures on a much bigger HDD drive. By doing that, you will have the superior speed of SSD and plenty of capacity from the HDD. Overall you get faster boot times, faster program and game launches.

It is a good idea to read through Amazon customer reviews, where you can find a lot of very useful information about the drive you have chosen to buy. To find the most reliable internal hard drive in the long term we looked at Backblaze data and other similar sources. 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. In the list below you can see the top best internal hard drives, for both laptop and desktop computers.

What can be easier than buying a internal hard drive, right?

Even for a non-expert in computers it is clear that internal hard drive plays a critical role in improving computers overall performance. The hard disk drives are storing all data and their main purpose is to access it based on user`s request. By choosing a reliable and fast hard drive (also called as HDD) you can dramatically improve systems speed, decrease boot times and game loading times. Your computer will start up faster and you will forget about long waiting for browser, files or folders to open.

At first look choosing the best internal hard drive to buy may seem quite easy, just find the biggest hard drive you can afford and your`e done right? No, it`s no that easy, especially when you go deeper and start to look at spindle speed (5200RPM, 5400RPM, 7200RPM), cache size (64mb, 128mb recommended), seek time, latency and warranty.

Various capacities and models themselves can easily mess up your head because they are so similar to each other. For example WD Blue series, as Western Digital states on product page – models up to 1TB capacity can be both 5400RPM or 7200RPM and models that are 2TB and more all are 5400RPM. The same things happens over time, if the internal hard drive is manufactured a year ago it can be different from the one which is just month old. You get the point, buying a hard drive is not as easy as it may seem, there are many factors that most buyers don`t ever notice.

You may end up with many questions before you know that the right internal hard disk drive is choosed. How much storage space do you need? Is it worth paying more for bigger capacity? Which cache size and spin speed is the best? Will one drive be enough or maybe you need an SSD storage?

What makes a good internal hard drive? – Relibiality

Picking the best internal hard drive is not just about speed and capacity. With more than ten years of experience as computer technician I very well know that just considering those two factors won`t give you a great purchase. You must take other essential factors like – cost per GB, customer reviews (Others people experience is very useful and you can found out problems and solutions you could not even imagine), brand reputation into the considiration.

But the most important factor of them all is hard disk drive reliability, high hard drive failure rate can lead to very big expenses and data loss. Here hard drive failure rate kicks in, how to know which is hard disk brand is more reliable?
There are two main things which can help you with that, it`s customer reviews and data collected from data centres like Backblaze. Backblaze is cloud hosting company they have almost 50k internal drives running 24/7. What makes their failure rate data even more useful for consumers is that they mostly use consumer grade hard drives.

The most reliable hard drive brands?

Is one hard disk drive manufacturer more reliable than other? To which you should trust your data?
From my own experience i can say that there is no – the most reliable hard drive manufacturer, everyone can get a lemon. Every drive can fail, no matter if it is Toshiba, HGST, Seagate or Western Digital. All these companies are big players and sell millions of hard disks each year, and the number is only increasing, of course some percentage of them will be damaged. How to avoid that? 

Consumer wants what he pay`s for, best things to do i go for the drive with longer warranty, it`s quite big difference if your drive has one year warranty like Toshiba HDD 5TB or much longer 5 year warranty like WD Black. If you choose to buy the one with 5 year warranty you know that you will have a hard drive for at least 5 years, no matter what, because if it`s fails you can get another one. 

So of course if you can`t afford to lose your data you need to make backups. Best thing to do is backing up your computer to both external hard drive and cloud service, or at least two external drives if you have a highly sensitive data you can`t backup to cloud (There is always risk for our privacy and we can`t trust cloud storage companies for 100%). 

What hard disk drive speed you need?

The speed of internal hard disk drive is one of the most important factors you need to look at before buying a hard drive. If you are serious about improving your system overall performance, go for faster internal hard drive which also would mean higher price.

But what is hard disk speed? Hard disk drive speed determines how fast all the data is transfered and accessed between CPU and hard drive, both back and forth, so you could also call it as system responsiveness.

Though internal SSD drives are much expensive, they are also much faster than mechanical hard drives and can noticeably improve system performance. In SSD storage devices speed is determined by electric circuit board but in mechanical HDD`s speed is limited by RPM (Revolutions per minute), platter spin speed. For technical reasons, the bigger RPM hard drive has the less data it stores. That means that 5400RPM HDD can store a lot more data in the same space than 7200RPM or 10000RPM.

Is there difference between speed and performance?

After many hours of researching internet i noticed that many tech-geeks don`t truly understand the difference between two terms ‘Speed’ and ‘Performance’. After reading these articles many people starts to think that hard disk speed is the one and only factor that can improve systems performance, of course it can, but you just can`t ignore many other aspects. Searching for the speediest hard drive and ignoring all other technical factors is a very bad thing to do. I will try to explain the difference between hard drive speed and performance so you won`t make mistakes and understand that speed is not the only factor that determines quality of hard drive. After all the many things the two main we want in our best internal hard drive is quality and reliability.

In dictionaries Speed is defined as „The rate at whcih someone or something is able to move or operate”. So that means that internal hard disk drive that access and transfers requested data in short period of time can be called ‘Speedy’? Of cource yes, but what about the quality of transfered data?

Imagine that you have ordered two MacBook`s online but used different shipping companies for each MacBook. Let`s say one company delivers your MacBook just in one day but it is complitely destroyed, it`s garbage. But the other company delivers it after three days but in perfect condition. Now, if i aks you which shipping company is better? Your answer definitely will be that second shipping company is much better. The same idea applies on hard drives, one can possibly be very fast and on the same time very low quality, which will result in corrupted files and the whole computing process will fail. While other hard disk drive will be slower but on this one all sectors on platters will be high quality and drive will fully deliver the bytes stored on them.

On the other hand, performance is measured by how intact data is stored and delivered by internal hard disk. As i already explained before many tech-geeks describes hard disk speed as a measure of performance depending on broader vision for „Performance”. I hope you understand the whole idea behind it. I just wanted my readers to be careful and not pick any hard drive just because it is said to be „speedy”, but to look further also on other factors.

Within this article we are talking about hard drives with SATA (Serial ATA) interface, which is the most common, standard interface for desktop computers and most laptops. SATA interface was introduced in 2001, all consumer grade computers employ SATA interface. However, high-end workstations and servers are often using SCSI serial interface (Serial attached SCSI). The SAS interface is typically used by fastest 10000RPM drives like WD VeloCiraptor, they usually have smaller capacities and are more expensive compared to lower RPM hard drives. Now that we have SSD drives with capacity more than 1TB, for affordable price, SAS drives is a part of history. Also, SSD drives are becoming more and more popular, many people are now choosing SSD instead of HDD. With each year SSD drives are becoming more affordable and with bigger capacities. At the moment you can buy 2TB SSD (Like Samsung T3 Portable, Samsung 850 Pro) for about 800-900$, still much more expensive than HDD which would be about 60-100$.

The four most popular SATA hard disk drive speeds are: 5400RPM, 5900RPM, 7200RPM, 10000RPM, RPM – Rounds Per Minute, it indicates how fast the drive`s spindle will move or how fast the platters of drive will spin. The higher RPM drives has the shorter the latency and seek time will be. There are also possible other spindle speeds like 5200RPM, 4200RPM and 15000RPM. The first HDD`s spun at 1200RPM, and 3600RPM was a standard for many years. Nowadays most consumer grade hard drives has 5400 or 7200RPM.

As far as i know, the only SATA hard drives with 10000RPM are from WD Raptor series, with maximum capacity of 1TB which will cost you little over $300. We only recommend this drive if you have older computer (before 2011) with SATAII port, otherwise SSD would be a better choice. Read our Best SSD top list if you want to find out more about them.

Our recommendation is to go for 7200RPM hard drives, they will provide high speed and performance for affordable price. Yes, they are more expensive than 5400RPM and 5900RPM hard disks and also uses more power. My opinion is that 7200RPM hard drive is better investment in long term, they provide speed i need, and i don`t care about capacity for my personal computer. Even 200GB of storage is totally enough for me, because i don`t have tons of photos, all unnecessary files i delete regularly and my work is not related to video editing or gaming.

In last few years manufacturers have implemented many new technologies in their storage devices to dramatically improve the performance and speed, power consumption and many other factors. Seagate Enterprise HDD v4 was announced as the fastest hard drive of 2015, it runs at 7200RPM spindle speed, with new architecture it is even faster than the legendary VelociRaptor that runs at 10000RPM spindle speed.

For home desktop computer and small businesses we recommend to go for 7200RPM internal hard drives

Who should buy 5400RPM or 5900RPM internal hard disk drives? These two speeds are mainly used in power efficient and cost effective systems, like data-centers and backup systems. This type of internal hard drives are recommended for people who needs a backup hard drive. Both 5400RPM and 5900RPM drives are widely used in SSHD (solid state hybrid drives). They are a hybrid between SSD and HDD, that will cost somewhere close to HDD, but will be quite faster, excellent for Laptops if you don`t wan to spend a lot of money for SSD.

As for backup hard drive we recommend 5400RPM or 5900RPM hard disks

How much storage space do you need?

Our need for storage devices are increasing each year, now that almost all of us have smartphones, laptops and personal computers the amount of data is generated enormously. When you are searching for best internal hard drive brand, one of the most important things everyone will look at is hard drive capacity, but how do you need? Notice, that sometimes bigger capacity is cheaper than smaller.

Advice from computer experts usually will be to find out how much storage space you need at the moment, then double that number for growth and then again double it, to make sure you have enough storage space for next five years or so. It`s universal rule, which will make sense in most cases when you are building personal computer. For example, if you have 2TB hard drive right now, then you should look at 6TB or 8TB hard drives for your next PC.

You need to answer – How will you use the hard drive? Do you need it for PC, Xbox One, Backup, home media center or enterprise server? Everything depends on your purpose.

Just for backup you want to go your 5400RPM or 5000RPM internal hard drives with bigger capacity, or 7200RPM is the system need to work fast.

Gamers would need faster drives, to be honest, for gamers, architects, video editors and any other heavy-user, the best solution is to have both SSD and HDD or SSHD. Idea is to store operating system on SSD so computer will work faster and to hold all other files like videos, photos on HDD with big capacity.

There are hard drives like WD Purple, which is specially designed for surveillance system that works 24/7, or Seagate NAS HDD which is designed for network attached storage (NAS) like Synology DiskStation DS214+.

People who are running servers should look at big capacities, 6TB or 8TB. Drives like Seagate NAS 8TB or WD RED PRO 6TB are recommended, they are especially designed for hard work in RAID configurations. Hard drive like Seagate Archive 8TB would be better for large system backups.

For user, like myself who has just Microsoft Office, few other programs and a small collection of family photos a 1TB or 2TB internal hard drive is more than enough.

Most Reliable Internal Hard Drive Brands

There are three best internal hard drive manufacturers – HGST ( aka Hitachi GST), Western Digital (WD) and Seagate. They are considered to be the most reliable hard drive brands. Western Digital, Seagate and Toshiba are the most well-known and most popular hard drive manufacturers.

As for Toshiba, it`s high authority, well known manufacturer also in many other niches, but in last few years their internal hard disk drives are showing high failure rates and are not so recommended. Although Toshiba claimed the improvement in their hard drive reliability there can`t be found any proof for that in real world testing reported by a trustworthy publisher. Their new drives like Toshiba 5TB HDD has become quite popular and gained pleasant customer reviews, but overal rating of 4 out of 5 stars is lover than competitor hard drives. We cannot strongly recommned Toshiba`s hard drives until there are good reports from trustworthy IT experts, like Anandtech, but we have included one of their best internal hard drive in our list.

Earlier there were bigger competition between hard drive manufacturers, there was other brands such as Maxtor, Samsung and others, but all of them left hard disk drive (HDD) industry. Samsung now focus on SSD drives, and they are good, the Samsung 850 PRO and Samsung 850 EVO are the most popular consumer grade solid state drives at at the moment. Samsung beats the competiton because they are one of those who creates new technologies and manufactur all parts of SSD. Visit Wikipedia to see list of defunct hard disk drive manufacturers.

The HGST was totally owned by Western Digital (WD) in mat 2012. The drives that are manufactured after WD bought HGST now are the most reliable. Just make sure you buy hard drives with new HGST trademark. At the end basically there are two main reliable hard drive brands to choose from – Western Digital (WD) and Seagate.

How did we make our internal hard disk drive recommendations?

Main aspects in choosing the best internal hard drive are: Endurance, stability and speed which all together will create „reability” of your internal hard drive. No doubt, performance is one of the most important factor of internal hard drive, it`s the quality how data is transfered, recieved and stored on internal disk.
