Frequently Asked Questions: 2TB Hard Drives

Who should get a 2TB Hard Drive?

In principle, a 2 TB hard drive is suitable for anyone who wants to expand the storage capacity on a device. 2 TB hard drives are also suitable for storing and transporting data or video material.

These data volumes should therefore also be quickly available to the user without long transmission data and loss of device speeds. 2 TB hard drives are therefore well suited for films, backups of electronic devices and large amounts of data.

First of all, it is important that 2 TB hard drives exist as HDD and SSD, but that SSD 2 TB hard drives are not profitable for many users due to the high price. SSD hard drives are more robust and have shorter access times, but the price of the 2 TB hard drives is much higher.

On the other hand, users should inform themselves before buying a 2 TB hard drive whether the capacity of the hard drive is sufficient or even too high. The capacity has a direct effect on the price. So if you only want to save holiday photos, a smaller hard drive model may be sufficient.

For everyday use, such as saving photos or videos from your last vacation, inexpensive hard drive models are often sufficient.

Do I need an 2TB HDD or a 2TB SSD?

A HDD hard disk (hard disk drive) is a magnetic storage medium for computers that permanently stores data. In contrast to HDDs, SSDs are usually faster in terms of their performance.

HDD 2 TB hard drives are more attractive in price than their competitors. Good hard disk drives can be purchased for as little as 50 dollars. Thanks to their storage volume, HDD hard drives are also particularly recommended for storing large amounts of data and creating archives.

The use of a HDD 2 TB hard drive is often cheaper if you can do without certain functions in terms of speed and performance.

SSD 2 TB hard drives, on the other hand, have the advantage that they are much faster in their data transfer than the competition. The high access speed makes the SSD hard drive a good storage medium for operating systems. If you save systems on an SSD hard drive, they can be put into operation immediately, almost without waiting times, if you open them.

SSDs are also more robust because they consist of fewer moving parts. The SSD hard drives are usually only available as an internal hard drive model. External variants of the SSD hard drive can be found on the market, but they are a lot more expensive than the HDD hard drive model.

Types of 2TB Hard Drives

With the same connection and model, internal and external 2 TB hard drives have no difference in quality and performance. It is important to note the extent to which the portability factor plays a role and which functions the 2 TB hard disk should have.

  • Internal 2TB Hard Drive
  • External 2TB hard Drive

Internal 2TB Hard Drive: Advantages & Disadvantages

An internal 2 TB hard drive can be used as a storage medium for PC and laptops. The internal 2 TB hard drive is inserted into the housing of the PC or laptop and connected to the mainboard. So it is permanently built into the device.

The fact that the internal hard drive is permanently installed with the device means that important programs, such as the operating system and other software, are stored on the device for regular use. Other important information can also be stored on the internal 2 TB hard drive. These include, for example, cookies, Internet files and information, as well as histories that are stored in the daily work with the device.

Many experts therefore advise regular control of the data on an internal hard drive. During this check, the hard disk can be reformed or defragmented, and other important files can be saved as a backup.

A major disadvantage of an internal 2 TB hard drive is that it is part of the device in which it was built. In the event of technical problems or defects, it cannot be easily removed from some devices. Many dealers therefore offer an exchange or repair of the internal hard drive as a service.


  • Just regular use
  • Quickly open files


  • Permanently installed with device
  • Regular checks are necessary

External 2TB Hard Drive: Advantages & Disadvantages

An external 2 TB hard drive can be connected from the outside at any time to devices whose connection is supported. External 2 TB hard drives usually have a USB port, which is used to connect the hard drive to the device.

Internal and external hard drives don’t necessarily have to be mutually exclusive. Most of the time, external hard drives are also used to store a backup of an internal hard drive. The data from the internal hard drive is copied to the external hard drive, which can then be stored. This increases the performance and capacity of the internal hard drive again.

The biggest advantage of an external 2 TB hard drive is clearly its flexibility and mobility.

By using the USB cable, an external hard drive can be connected quickly and easily to various devices. Many 2 TB external hard drives are perfected in their weight and size for the consumer, so they can be easily carried with you.

Another important advantage is their compatibility. Many external hard drives have a USB port that can be connected to all commercially available models of computers and game consoles. For computer models from Apple there are also hard disks with a USB-C connection or suitable adapters.

When choosing an external hard drive, the user should pay attention to its robustness. If the external hard drive is always to hand with you, there is a risk of damage and loss. In addition, you should also consider the location of an external hard drive, since, for example, heat and cold can have negative effects.


  • Flexibility and mobility
  • Easy connection


  • Robustness and Loss
  • Outside influences

2TB Hard Drive: Purchase Criteria

In the following we will show you which aspects can help you choose the right 2 TB hard drive that meets your needs.

The criteria that you can use to compare the 2 TB hard drives are:

  • Compatibility
  • Usage
  • Size & Power Supply
  • Price-Performance

In the following paragraphs we will explain to you what is important for the individual criteria.


In terms of compatibility, a distinction must again be made between internal and external hard drive models. There are many different connections for internal hard disks (ATA, SATA, SCSI, SAS). It is therefore important that you find out exactly which connection you need when buying.

New SSD internal hard drives usually have a SATA interface, at least the cheap and affordable standard SSDs. There are also faster interfaces, but they are much more expensive than their counterparts. These new models can only be used by modern operating systems and thus achieve their full performance.

Generally applies to the SATA class

1.5 Gbs

SATA II (also Sata 2.x, SATA 300)
3.0 Gbs

SATA III (also Sata 3.x, SATA 600)
6.0 Gbs

Most PCs already have such a SATA interface. You can easily look up which SATA version is on the Internet. To do this, you enter the model and manufacturer names in the search and see which SATA version your mainboard supports. It is important here that the transmission speeds match.

SATA versions are backwards compatible. If a new SATA 3.0 or SATA 3.1 SSD is connected to an older SATA 2.x / SATA II mainboard, the transfer speed will be dragged, but it has no effect on the files.

There are also various programs that can help you find the right internal hard drive.

In the case of external hard drives, the connection is simply to be observed. The new models currently have a USB-3 connection. MacBook models already have a USB-C port. If it is an older computer model, Firewire 400 or Firewire 800 may still be available as a connection.

Each hard drive also has its respective connector. It is therefore advisable to find out exactly which connection the device has and whether an adapter is necessary before buying.

In principle: USB-3 is now standard for many new devices. USB-3 or USB-C are also much faster in transmission than their counterparts. Alternatively there is the eSATA connection, which can transfer data just as quickly.


External 2 TB hard drives are also suitable for storing and transporting data or video material. For most users, a classic HDD hard drive is sufficient. For example for backing up photo and / or video material. It is also interesting that if data is lost, it can usually be restored. This depends entirely or only partially on the situation.

Experts recommend buying a simple 2.5 inch HDD hard drive for the simple protection of video, music or photo material. Although they are slower than the larger models, they are more affordable and perfectly adequate for use.

2.5 inch hard drives are usually 5400 revolutions fast.

Size & Power Supply

In addition to the external and internal version, the 2 TB hard drive can also be distinguished in terms of size. Internal hard disks that are built into the PC are usually 3.5-inch. The 3.5-inch models can move in higher storage capacities without sacrificing speed. Therefore, these models are mostly found in built-in form.

2.5-inch hard drives are particularly advantageous as external hard drive models. They are easy to handle and fit in a jacket pocket. 2.5-inch models do not need their own power supply and are therefore more mobile in their use.

External hard drives with a USB connection are available in both sizes. Due to their higher storage capacity, 3.5-inch hard drives usually need their own power supply. Due to the power consumption, an external 3.5-inch hard drive would be less profitable for everyday use. These models can therefore be used as a storage medium for back-ups.

In addition, the 3.5-inch models are more unwieldy and simply heavier due to their size. But if you need a lot more memory, you should definitely use the 3.5-inch models.


In general, when it comes to the price-performance ratio of hard drives, attention is paid to how high the price per gigabyte is. With external 2.5-inch HDDs, our 2 TB model is comparatively best. For the 2 TB 2.5-inch hard drive, the price per gigabyte is around five cents.

When choosing the right 2 TB hard drive, the purchase criterion should be taken into account as a criterion, but not decisive.

Nevertheless, it is advisable that the price should be seen as the final purchase criterion or at least in relation to the other purchase criteria. Most of the time, many price ranges are already mutually exclusive when it comes to the intended use.

But you also have to be aware that more performance automatically means a higher price range. If you need a certain speed or a special feature, you have to pay extra accordingly.

Facts about 2TB Hard Drives

How do I properly format a hard drive?

Correct formatting of a hard drive can vary from operating system to operating system. In the following we explain the formatting process with a Windows (7/8/10) and an IOS operating system.

Caution: Formatting a hard drive will delete all data on it!


  1. Start the system: First you press the key combination Windows + E to open Windows Explorer. Opens the computer (Windows 7) or This PC (Windows 8/10).
  2. Select hard drive: Right click on the hard drive that you want to format. Now select the Format entry and enter a name for the data carrier in the new window.
  3. Start formatting: Click on the Start button to start formatting. Confirm the warning that appears in a new window with OK. Formatting will delete files, so the computer will ask for your consent.
  4. Complete formatting: After a short time, formatting is complete and all data on the hard disk are deleted. Now you can upload new files and data to the hard drive.


  1. Starting the utility: First, go to Applications and then Utilities. Then you go under the item Disk Utility. You can also use the shortcut Command + Shift + U for this.
  2. Beginning of formatting: Now mark the hard drive or partition that is to be formatted. When you press delete a pop-up will appear. Here you give the hard drive to be formatted a name and select Mac OS Extended (Journaled) from the drop-down menu.
  3. Complete formatting: If you now click on delete, another control question appears. After a short time, the formatting will be completed and all data on the hard drive will be deleted.

How do I connect my hard drive?

When connecting the hard drive to the device, we need to distinguish what type of hard drive it is.

  • External 2 TB hard drive
  • Internal 2 TB hard drive

When buying an external 2 TB hard drive, it is important to find out which connection you need beforehand. Therefore, check whether the device has the necessary and suitable connections. For example, fast hard disks usually run via a USB 3 interface or via eSATA. You can always find this information on the back of the packaging or in the information section for the respective article in the online shop.

The connection is then fairly easy. If all the necessary cables and connections are available, connect the 2 TB hard drive to the device in the port provided.

My hard drive is not recognized - what can I do?

Hard drives should always be automatically recognized by the PC and operating system. These are then automatically marked with a new drive name. If this is not the case, here are a few tips.

Problem 1: Drive Label

With operating systems it is important that the hard disk can be found in the directory as a storage medium. This is done by assigning a drive letter such as E. It can happen that the automatic assignment of a drive letter does not work. A simple solution to this problem is to assign the drive name manually.

Problem 2: Partitioning

A newly purchased hard drive is usually designed to be user-friendly and can be put into operation immediately. Nevertheless, it sometimes happens that some hard drives cannot always be used as quickly. Partitioning can be an important point of failure here.

Partitioning here means that the hard disk is divided into two or more separate storage areas. These partitions on a hard disk can then, for example, also be used by different users of the same device.

Nevertheless, it is good to think about the correct partitioning of the purchased hard drive and to adjust it if necessary. If you want to partition your hard drive, find out about the storage space required for the operating system. It is always an advantage to give the operating system its own partition.

Below we explain the most important steps to partition a hard drive with a Windows 10 operating system:

  1. Open Disk Management: Select the Disk Management menu item in the left column of the window. If you cannot find the menu item immediately, you can also easily find it using the search function.
  2. Beginning of partitioning: All partitions on the hard disk are now displayed. A new hard drive usually has only one partition. Now click on the system partition and select the Shrink Volume item. Now you can choose how much space you want to have for a partition and how many partitions you want to divide your hard drive into. Confirm this step.
  3. Finish partitioning: Windows will now show you a new window and start an assistant. The wizard helps to assign the given partitions with the corresponding number of mega-, gigabytes or terabytes.

Problem 3: Power supply and / or connection failure

If your hard drive is not recognized, external influences can also play a role. It is important that you first check whether the USB cable is correctly connected to the hard drive and is also plugged into the correct port on the device.

Incorrect removal of the external hard drive can lead to problems.

Furthermore, there may be errors in the detection, for example if the hard disk was not properly logged off after use. Here it is important to remove an external hard drive from the device using the “eject” function. Incorrect removal of the hard drive can damage files.

Another important factor is that you only use the attached cable for the connection of the external hard drives. Or at least a power supply that meets the demands of the hard drive. Wrong cables can lead to overvoltage and thus to defective electronics.
