HDD Test: The best HDDs 2021 in comparison
The big HDD hard disk guide – Everything you need to know before buying!
In this section, we clarify different questions on various topics related to HDD. Here you will learn how HDDs actually work and learn more about the technology behind HDDs.
We also give you valuable tips for evaluating hard disks before you buy them, so that you can select, buy and install the best hard disk for your personal requirements in your system!
What is a HDD and how does it work?
HDD stands for“Hard Drive Disk“, the magnetic storage medium in all HDD hard drives. In HDDs, data is written to a hard magnetic surface coating on the rotating disk(i.e., the actual hard disk) by magnetizing the surface without contact.
The data is thus stored in the form of the remaining magnetization of the hard disk and can be retrieved when the stored information is read by scanning the magnetization with the help of a sensor on the hard disk surface.
HDD hard disks can only store information in data blocks, which have a fixed size depending on the hard disk – for example 4096 bytes. So the total storage size of the disk depends on the number of blocks and the size of the blocks.
The further apart the storage blocks are, the higher the read speed of the HDD. Typical sizes of hard disks are for example 2.5 inch and 3.5 inch, whereby in the 2.5 inch segment rather laptop HDDs are represented which have to meet size requirements.
Briefly summarized: HDD hard drives work with magnetic storage disks on which various data is stored and retrieved by magnetization without touching. There are different sizes of HDDs, and their read and write speeds can vary significantly.
How much will an HDD cost me?
We have examined both internal and external HDDs in our HDD comparison and found that there is practically no price difference between the two variants. Both types of hard disks are available at a price of just under 34.99 $ with a size of one terabyte and about 7200 revolutions per minute, which may be good for the write and read speed.
Fast hard disks with two terabytes are available for purchase on the Internet from around 59.99 $. For about 89.99 $ you can also buy good hard disks with four terabytes, which have many revolutions and the SATA connection. If you are looking for a powerful and large hard disk with a lot of memory, then you should invest about 50 – 60 $ in order to have a lot of joy with the new hard disk for a long time.
HDD hard disk test – Useful accessories for your new HDD
If you are looking to buy a new HDD, there are also a lot of accessories on the market that you can use with your new HDD. These include data cables, which you need to connect your hard drive to the mainboard.
Or even adapters, such as a SATA to USB adapter, which allows you to connect your hard drive via a USB interface.
SATA: What does that mean?
The abbreviation “SATA” stands for Serial AT Attachment and is a computer interface for hard disks to exchange data. The normal SATA standard can transfer data at speeds of up to 6 Gbit/s, while SATA Express hard drives connect to a computer via the PCIe connector and can achieve data rates of up to 16 Gbit/s.
The net data rate of conventional SATA connections is 600 MB/s, Express hard disks manage up to almost 2000 Mb/s. SATA Express hard disks are also significantly more expensive.
SATA is simply a computer interface for hard drives. This is differentiated between SATA standard and SATA express. The difference is simply in the speed at which data is transferred.
HDD or SSD hard disk? – The main differences, advantages and disadvantages
Should I upgrade to a simple and inexpensive HDD or go for the faster and more expensive SSD? If you ask yourself this question, you must of course determine your personal requirements for the new PC system and decide on one of the two hard disk variants on the basis of this decision.
Nevertheless, we would like to note down all the important differences between HDD and SSD hard disks for you here again. The clear advantage of SSD hard disks is the non-mechanical mode of operation, which makes an SSD hard disk significantly faster than an HDD hard disk.
On the other hand, SSDs have an overall shorter lifespan, less storage for the same money, and therefore a higher total cost of ownership. HDD hard drives are inexpensive and have plenty of memory, which smart PC wizards use to store files they don’t need to access frequently. All in all, one can already say that both types of hard disks are most worthwhile at the same time.
For the operating system and frequently used (multimedia) applications, the SSD hard drive is suitable; for less required data and information, you can confidently use an HDD.
How large should the memory of my HDD be?
If you decide to buy a new HDD and ask yourself how much storage it should offer, the only thing that really matters is the budget. If you’re willing to spend around 50-60 $ on your new hard drive, you can upgrade to mid-range models that are quite fast for HDDs and have plenty of memory.
But there are also cheaper HDDs with about two terabytes of storage space that you can order for very little money on the Internet – of course, there are also more expensive HDDs, which then cost up to 150 $ and more, but provide a lot of memory.
What is a Hybrid Hard Disk Drive (SSHD)?
Hybrid hard drives(SSHD, Solid State Hybrid Drive) are a combination of the HDD hard drive and the more powerful SSD hard drive(Solid State Disk). They are supposed to combine the advantages of both types of hard disks: a low price and high performance. This works because SSHDs have internal flash memory that enables fast data transfer rates.
In addition, SSHD hard drives consume less power than SSD hard drives because the mechanical read and write head does not always have to be activated thanks to the flash memory. This also leads to an increased lifetime compared to normal SSD hard disks – SSHD hard disks are thus a good compromise between HDD and SSD hard disk variants.
New hard drive? This is to be considered with the purchase!
What should be important to me when buying my new hard drive? If you are asking yourself this question, you should definitely read this section. When buying a new hard drive, you should of course always plan and set a certain budget before you start looking for a new hard drive.
This way you can be sure that you didn’t end up spending more money than you originally intended. Once you’ve set a budget, you can begin a thorough search for your new HDD hard drive.
When buying a HDD, you should pay attention to the price-performance ratio and the number of revolutions per minute if you really want a good hard disk. You can simply divide the price of the fallen hard disk by the number of gigabytes offered and thus calculate the price per gigabyte and compare different manufacturers.
Of course, branded goods are always a bit more expensive than no-name products, but usually the investment in hard disks from Seagate, Crucial and Western Digital as well as others is worth it.
Install HDD hard disk: This is how it works!
- Step 1Before you install your new HDD, you should first shut down your PC and unplug the power cord from the power outlet. To avoid accidentally damaging a circuit board with the electrostatic charge of your body, you should ground yourself first. You can do this quite simply by touching a radiator.
- Step 2Now you can loosen the screws of the PC case and remove the side panels. Then you should carefully disconnect the 2 cables from your old hard drive and remove the hard drive. Once you have done this, you can start looking for a suitable slot for your new HDD.
You should make sure that there is enough space between the drive and other components. Now connect the 2 cables to your HDD and make sure that the HDD is firmly installed in the case.
- Step 3Now you’re almost there! Now just check that all the cables are connected correctly and then screw the side panels back onto the case. Now plug your computer back in and check if it boots up as usual. If that’s the case, you’ve done everything right…!
HDD hard disk drives test: Conclusion
Now you know everything you need to know about HDDs to make a good decision when buying your new hard drive. You can explain what SATA means, how mechanical HDDs work and know the differences between HDD and SSD hard drives.
You’ve also been introduced to SSHD hard drives, which aim to create a good compromise between the two types of construction.
Now it’s up to you: Choose your new hard drive and benefit from more storage space on your computer soon!
