Frequently Asked Questions: 500GB SSD

What is a 500GB SSD?

The term SSD means “Solid State Drive”. An SSD is an electronic storage medium with different storage capacities for your computer or laptop.

The use of the SSDs is to store and read data. In contrast to “hard disk drives”, called HDDs, your data is not written to a magnetic “disk” with a write head, but digitally stored on the storage medium, similar to USB sticks or memory cards. This enables the SSDs to have fast access times and work quietly.

In addition, the SSDs have a robust construction that makes the memory insensitive to vibrations. For this reason too, SSDs are becoming increasingly popular in mobile devices.

SSDs can be differentiated between internal and external SSDs. The internal SSD is permanently installed in an interface of your computer or laptop. The external one, on the other hand, is portable and is connected to your device via a USB cable.

The 500GB SSDs have a storage capacity of 500 gigabytes. Which usually offers enough space for games, photos, videos, documents, operating settings or even for your operating system. It’s also clear: the larger the SSD, the more it can store.

Is a 500GB SSD big enough?

As a rule, 500GB SSD is sufficient for every user and is comparatively cheap. Nevertheless, we present you with key decisions that the buyer of a 500GB SSD should consider.

The 500GB SSD must be large enough to store your current data, which you have on your computer, laptop or other storage medium, for example. Plus the data you will continue to accumulate over the next few years. Media files are large and take up a lot of space on your 500GB SSD.

If you are someone who takes a lot of photos and videos and also stores this data on an SSD, then a 500GB SSD will be tight. The same goes for those who must have every new computer game. The fuller the 500GB SSD, the weaker the performance that can be provided.

The largest SSD available is an advantage, but what use is it if you only use half of it? SSDs that are too large are a waste of money.

Therefore, you should be clear about what your SSD is used for and whether the right amount of storage is available.

500GB SSD Alternatives

There are different alternatives to the 500GB SSD as a storage medium. Each alternative has its advantages and disadvantages. In the following section we will give you a brief overview of the HDD and SSHD.

Hard Drive Disk “HDD”
Often referred to as a hard drive, it consists of a magnetic storage medium and a write head. The write head writes the data on the surface of the rotating platters.

Solid State Hybrid Drive “SSHD”
Is a hybrid hard disk, which consists of a hard disk, like the HDD and a flash memory, like the SSD. The flash memory is supposed to ensure shorter reading and writing speeds.

The alternatives also have their advantages. Nevertheless, the SSD has been an integral part of the end customer market since 2007.

Types of 500GB SSDs

Basically, the 500GB SSD can be divided into two different types of products:

  • internal 500GB SSD
  • external 500GB SSD

But the two products can hardly be distinguished in terms of their performance and their service life. Depending on the area of application, an internal or an external 500GB SSD offers advantages and disadvantages. In the following section we would like to give you reasons for the internal or external 500GB SSD so that you can make a decision.

Internal 500GB SSD: Advantages & Disadvantages

The internal 500GB SSD is characterized by its fast read and write speed. This means that the data can be called up after a short time. The internal 500GB SSD can be used by everyone who wants more performance and shorter loading times for their computer or laptop.

The robust construction, which contains no moving parts, makes the internal 500GB SSD insensitive to vibrations. In addition, the SSD consumes little power and therefore needs little cooling.


  • Fast read and write speed
  • Robust and small design, makes it light and insensitive to vibrations
  • Digital storage, reduces noise emissions


  • The 500GB SSDs can only be written to once
  • A free interface is required, which is often only available in computers
  • Not suitable as a portable storage medium

The required free interface gives the internal 500GB SSD additional security, as it is permanently installed in your computer or laptop.

In most cases, free interfaces are only available in computers, since every centimeter is built into the compact laptops. If an interface in your laptop is still free, it is often very tedious to install the internal 500GB SSD.

No cable is required for the internal 500GB SSD as long as an additional interface is available.

An internal 500GB SSD is suitable for those of you who have a free interface in your computer and rely on permanently installed storage media.

External 500GB SSD: Advantages & Disadvantages

The technology of the external 500GB SSD is the same as that of the internal 500GB SSD. Therefore, the two types cannot be distinguished in terms of their performance, their structure and their service life.

The external 500GB SSD is connected to a free USB port on your computer or laptop via a USB cable. With the connection via the USB cable, no free interface is required, just a USB port. This makes the external 500GB SSD a mobile alternative to the internal 500GB SSD.


  • Fast read and write speed
  • Robust and small design, makes it light and insensitive to vibrations
  • Digital storage, reduces noise emissions
  • Mobile by connecting to a USB port


  • The 500GB SSDs can only be written to once
  • Expensive alternatives in the lower price segment
  • Risk of loss as it is not an integral part of your computer or laptop

The external 500GB SSD is suitable for those of you who own a laptop or who do not have a free interface in the computer. The external 500GB SSD is also a sensible alternative for people who work from anywhere.

500GB SSD: Purchase Criteria

In the following section we will show you which aspects you can use to decide between the multitude of possible 500GB SSDs.

The criteria with which you can compare the 500GB SSD with each other include:

  • Read & Write Speed
  • Lifespan
  • Dimensions & Weight
  • Connections

In the next few paragraphs we will show you what to look for in the individual criteria.

Read & Write Speed

As already mentioned, the read / write speed of 500GB SSDs is significantly higher than in comparison to other storage media. This allows the user better performance and shorter loading times.

Information on the speed can be found in the technical data and is in most cases given as the data rate in combination with the output and input operations per second.

The higher the data rate, the faster large amounts of data can be stored or accessed. If the device is in operation for a long time, the output and input operation decreases with increasing use.

There are differences in read / write speed between the internal and external 500GB SSD in the various price segments.

In the lower price segment, internal 500GB SSDs have a read speed of 560 MB / s and a write speed of 530 MB / s.

In the upper price segment, the internal ones have a read speed of 1100 MB / s and a write speed of 700 MB / s

Favorable versions of the external 500GB SSD have an approximate read speed of 540 MB / s and a write speed of 500 MB / s.

Depending on the manufacturer, the expensive alternatives to the external 500GB SSD achieve read speeds of up to 2800 MB / s and write speeds of up to 2600 MB / s.


As with other devices, you get a warranty of 2 to 5 years for a 500GB SSD, depending on the manufacturer. However, the warranty doesn’t say very much about the actual lifespan of a 500GB SSD.

In the technical information you will find information about the stamina of a 500GB SSD in the form of write cycles that can be achieved. The most common specification is the TBW (terabytes written) value. The value is closely related to the storage capacity.

Otherwise, the MTBF (Mean Time Between Failures) value is in the technical data, which indicates the mean operating time for repairable devices. The operating time is the operating time between two successive failures.

An expensive internal 500GB SSD has an MTBF of 2,000,000 hours.

The expensive alternative of external an MTBF of 1,500,000 hours.

Dimensions & Weight

In addition to the technical data mentioned above, the dimensions and weight are also important purchase criteria.

Technically, both variants are between 40 and 200g in weight. Cheap variants are usually lighter than their expensive competitors.

The internal and external 500GB SSDs can differ in size. Depending on the size of the interface, the 2.5 inch version or the 3.5 inch version can fit into your device.


The last important purchase criterion for us is the connections.

The internal 500GB SSD is available in two forms. Either as an M.2 plug-in card that is placed in an M.2 slot or as a 2.5 or 3.5 inch housing that is installed in the appropriate frame on the mainboard. In addition, the M.2 plug-in cards can be connected either as NVMe / PCIe or as SATA.

Significantly higher amounts of data can be transferred via the NVMe / PCIe connection than with SATA.

With the external alternatives of a 500GB SSD, which can be bought as either a 2.5 or a 3.5 inch housing, the USB cable is included. This allows the external 500GB SSDs to be attached to all devices with a free USB port.

In order to achieve the maximum performance of the external 500GB SSD, the connection type plays an important role. The latest devices have a USB3.1 connection, which must be supported by the end devices, be it computer, laptop or television.

Facts about 500GB SSDs

How to install an internal 500GB SSD?

The following section explains how to install an internal 500GB SSD. Basically, the storage capacity of the internal SSD is unimportant because the installation works in the same way for all of them.

In order to be able to install the internal SSD without problems, you should check your computer for three things:

  • Power supply: To supply the SSD with power, it needs a connection to the power supply unit
  • Mainboard connection: There are different connections depending on whether it is an M.2 plug-in card or a 2.5 or 3.5 inch housing. The housing needs a SATA connection. The card, on the other hand, has an M.2 slot.
  • Insert: The 2.5 or 3.5 inch housing needs a suitable insert in which a frame provides support.

The installation is carried out as follows:

  1. Before opening the casing of your computer, be sure to unplug the power cord from the socket.
  2. Loosen the screws on the housing to remove the side panel.
  3. Place the computer open-side up on a flat surface.
  4. Find the power connection to which five cable cores lead and the SATA connection to which only a visible ribbon cable leads. (If you have problems finding the connections, orientate yourself on the already installed hard drives)
  5. Connect the internal SSD to the appropriate connectors.
  6. Install the frame of the hard disk bracket to fix the SSD in the computer.

How do I initialize a 500GB SSD?

First, you should know in which cases you need to initialize your 500GB SSD. There are 3 main cases that cause users to initialize their SSD:

  • New SSD is not displayed: Your new SSD will not be displayed after you have connected it. The initialization makes the SSD visible.
  • SSD is not recognized: The error occurs frequently in Windows 10/8/7. Initialization solves the problem.
  • LDM cannot access this SSD: The case occurs when your file system is not GBT or MBR. The disk must be initialized before you can access it.

To solve the problems, there are two possible solutions for you.

Solution 1: Initialize your SSD through disk management.

  1. If you press the Windows + R key, the window opens with “Run”
  2. There you enter “diskmgmt.msc” and press OK.
  3. Disk management opens. There you have to find the data carrier to be initialized and right-click to select the data carrier initialization.
  4. Then set the file system to GBT or MBR, restart the computer and access your SSD.

Solution 2: Initialize the SSD using Diskpart commands:

  1. Press the Windows + R key and open the “diskpart” program. Confirm with Enter.
  2. Then you type in “list disk” and press Enter.
  3. Type “select disk G” and press Enter (replace G with the drive letter of the uninitialized hard drive).
  4. Then “clean” is entered and confirmed with Enter.
  5. Then enter “convert gpt” or “convert mbr” and press Enter.
  6. Type in “create partition primary” and hit Enter.
  7. Enter “format quick fs = ntfs” and confirm with Enter.
  8. Type “assign” and hit Enter.
  9. Type “exit” and hit Enter.

How do I clone a HDD to a 500GB SSD?

  1. First, you have to download and install the free tool “Partitation Wizard”.
  2. An HDD usually has more storage space than an SSD. It is therefore important to clean up the hard drive beforehand and to create a backup.
  3. Connect your SSD to a USB-SATA adapter on your computer and open the Partition Wizard.
  4. Then click on “Wizards” and then on “Migrate OS to SSD / HD Wizard” and select your SSD as the target network.
  5. Next, you can adjust the size of the partitions.
  6. In the final step, click “Next” and then “Finish” to complete the process. Then the HDD is cloned to the SSD.
