Frequently Asked Questions: 1TB SSD

Who should use a 1TB SSD?

A 1 TB SSD hard drive is suitable for anyone who wants to expand their storage space on a PC or laptop.

Depending on whether you work mobile or not, the shape of the SSD hard drive can be part of the purchase decision. If you need a lot of storage space, a hard drive with more storage space may be more suitable.

Because SSD hard drives are very light and only have a small size, they are very handy and are very suitable when your own memory runs out to create more space to store more data.

1TB SSD Alternatives

An alternative to the 1 TB SSD is a hard disc drive. This is also available in larger storage capacities than SSD hard drives. There are HDD and SSD models with different storage sizes, so that the right capacity is included for you.

Different storage sizes for SSD and HDD are offered.
If you are looking for a mobile way to access your data, numerous providers also offer online storage, for example Google Drive or the Apple Cloud. The advantage of online storage space is that it can be accessed from anywhere with the Internet. The disadvantage is that you can only access the relevant files via the Internet.

Therefore, online storage expansion is not very suitable, for example, to speed up your computer or to outsource programs, but this is quite possible with SSD hard drives.

An internal hard drive, however, is more expandable than the SSD hard drive and works with moving parts, therefore not mobile

Types of 1TB SSDs

A basic distinction is made between two different types of 1 TB SSDs:

  • internal 1 TB SSD
  • external 1 TB SSD

Both options offer advantages and disadvantages, which are primarily determined by your own PC equipment and the intended use. This includes factors such as mobility, or whether your own PC is a fixed PC or a laptop.

Internal 1TB SSD: Advantages & Disadvantages

If you install a 1 TB SSD internally, you have the great advantage that you have no external devices around you. This is not annoying with a fixed PC, but as soon as you have a laptop and it is always necessary to carry a 1 TB SSD with you, it can quickly become annoying.

Another great advantage of installing your hard drive directly into your PC or laptop is the read and write speed. While a hard drive can often be slowed down with a USB connection, the direct connection can result in significantly higher speeds.

In addition, internal SSDs allow more write cycles and thus have a longer service life than similar competing models. However, it can also be difficult if your SSD hard drive breaks because you have to remove it first. You also have to take the whole PC with you if you want to take it with you


  • Everything compact in one place
  • Very fast reading and writing speed
  • Long service life due to more write cycles (compared to the external SSD)


  • Not easy to expand
  • Bulky because you have to take the whole PC with you
  • More difficult to install than an external SSD

External 1TB SSD: Advantages & Disadvantages

The storage space of your computer is full again and you are overwhelmed with error messages? So you’re looking for a short-term solution to expand your storage space? Then an external 1 TB SSD hard drive is just right for you!

It is installed in just a few simple steps and connected to your computer using, for example, USB. So you have a terabyte of storage space for videos and media in just a few minutes!

The big plus is the mobility of the 1 TB SSD, for example if you have to change your location from time to time because you sometimes work in the home office and sometimes in the office, you can easily take all the important data with you.

However, you should make sure that your computer has at least a 3.0 USB port, because when connected to this, data transfer is up to ten times faster than with a USB 2.0 port.


  • Can be easily connected via USB
  • Portable so you can take it with you wherever you go


  • Slow if you don’t have a USB 3.0 port
  • Often slower than internal hard drives

Purchase Criteria: 1TB SSD

Do you want to buy an SSD hard drive? In the following we would like to show you the criteria you can use to evaluate 1 TB SSD hard drives and make a decision. This makes it easier for you to choose a specific product.

In summary, these are

  • Connection type of 1 TB SSD
  • Size and height of 1 TB SSD
  • Read and write speed of 1 TB SSD 
  • Design for 1 TB SSD hard drives (external)

Connection Type

1 TB SSD hard drives can be connected to the computer in a variety of ways. How the connection is established depends primarily on whether you want to connect an internal or an external 1 TB SSD hard drive.

Connection types for internal 1 TB SSDs

If you have chosen an internal 1 TB SSD hard drive, you can connect it to your computer in three different ways. To do this, you either have to open the case of your computer or the case of your laptop. If you are not familiar enough with it, you should hire a professional:

  • SATA
  • PCIe
  • m.2

Connection types for external 1 TB SSDs

External 1 TB SSD hard drives can be connected in two different ways:

  • USB
  • Thunderbolt

It should be noted, however, that at least one USB 3.0 port is available, because the data transfer for USB 2.0 is about 10 times slower than with the newer version. Many applications are therefore not possible with the old version.

To connect the 1 TB SSD, you can simply use the corresponding Thunderbolt or USB cable.

Size & Height

The size and height of 1 TB SSD hard drives varies with the different models. A basic distinction must be made between the internal and the external hard drive.

In the case of the internal 1 TB SSD, the size is more important, because even minor deviations can no longer fit into the housing of your laptop or computer. For internal 1 TB SSDs, you can basically choose between 2 sizes

  • 2.5 inch form factor
  • M.2 form factor

External 1 TB SSD

  • 2.5 inches
  • 3.5 inches

Read & Write

The read and write speed of 1 TB SSDs is standardized between 500 MB / s and 560 MB / s, there are no major differences here. The speed differences mainly depend on how your 1 TB SSD is connected to your computer or laptop.

If you need a fast connection, you should pay attention to the connection type of your 1 TB SSD hard drive when buying.

Design (External SSDs)

Of course, only external 1 TB SSD hard drives have a relevant design. Since you build internal 1 TB SSDs directly into your PC, the design does not really matter here.

However, if you should opt for an external SSD hard drive, you have a wide range of different designs. It is best to pay attention to awards such as water resistance and dust resistance, so that nothing happens to your hard drive during transport.

Facts about 1TB SSDs

How do I install a 1 TB SSD?

How you install a 1 TB SSD hard drive is particularly important for the internal hard drives, because you only have to connect the external 1 TB SSD with the Thunderbolt or USB cable.

To install internal 1 TB SSD hard drives, you must first check whether your device still has enough space. Depending on whether you have decided on an M.2, PCIe or SATA connection, you should connect the 1 TB SSD hard drive with an appropriate cable.

Most of the time, the corresponding cables are included with the purchase, but be sure to pay attention to them before buying, because most of the times all cables are already assigned in a pre-assembled PC or laptop. So buy a cable with a suitable connector if necessary.

You should then connect the cable to the computer’s motherboard to establish a connection. If this worked, the additional 1 TB SSD hard drive should be displayed in your Finder the next time you start your device. Then you can close the case of your device again.

However, when positioning your 1 TB SSD hard drive, make sure that the hard drive is securely positioned to avoid free play. This is particularly important in the case of portable devices such as laptops.

What does the abbreviation SSD mean?

The term SSD stands for “Solid State Drive”.

This is in contrast to its sister, the HDD hard drive. This term stands for “hard disc drive”. In contrast to this, the SSD hard drive does not work with moving parts.

What should you watch out for with an SSD?

In general, you should take good care of them and defragment them regularly. This helps to remove unnecessary files from the drive and ensures a longer life for your 1 TB SSD hard drive.
