Solid-state drives (SSDs) have changed how we store and access information on our computers in the age of digital technology. 

SSDs have become popular for many people who want a green and reliable way to store their data because of how quickly and well they work. However, the fact that the operating system’s display of actual available space doesn’t always match the SSDs’ advertised storage capacity is something that users frequently find confusing. 

This article aims to clarify the mystery behind this hard-to-solve problem by explaining what causes the difference between what your SSD shows as space and what is advertised.

Why Does My SSD Show Less Space?

Operating systems calculate storage potential using the binary system, where 1 kilobyte equals 1,024 bytes, whereas producers use the decimal machine, where 1 kilobyte equals 1,000 bytes. This discrepancy results in a slight decrease in the SSD’s displayed capacity.

Capacity Differences

One of the main reasons your SSD may show less available space than expected is that manufacturers and operating systems measure storage capacity differently.

Manufacturers say that 1 gigabyte (GB) equals 1 billion bytes, but operating systems see it as 1,073,741,824 bytes. So, if you buy an SSD that says it has a certain amount of space, like 256GB, the running device will show a slightly smaller amount of space is available.

Let’s think about a 256GB SSD to show how this works. When you translate this ability into your device’s language, it comes out to about 238.4GB. The 17.6GB that isn’t there isn’t lost. Instead, it’s because different measurement standards are used. So, the difference you’re looking at is just a count of how capacity is measured and reported.

File System Overhead 

The file system overhead is another thing that makes an SSD have less space than a hard drive. When you format an SSD, the working device makes a document device that organizes and handles the data on the drive. This method only uses a small amount of the space needed to store important device papers, metadata, and indexes.

Formatting Type

Depending on the file system you use, such as FAT32 or NTFS on Windows or APFS on macOS, the amount of space the file system uses can vary. Also, the cluster size picked during formatting can affect how well storage space is used, which could cause small files to waste space. Even though these overheads are necessary for the file to work correctly on the device, they take up room on the SSD.

Hidden System Files and Partitions

Operating systems often create hidden machine files and partitions on hard drives for various reasons. Most people don’t see these files and walls, but they still occupy some of the SSD’s spaceThe Windows Recovery Partition, the macOS Recovery Partition, the sleep record, and the page record are good examples.

Device recovery, caching, and managing virtual memory all depend on these files and folders. But they add to the feeling that your SSD has less room than you thought. You can use disk management tools or check the powerhouses on your system to see if hidden device files are taking up a lot of room.

Why Is My SSD Full When There Are No Files?

It is because of the reserved space for system restore, temporary files, hidden files, and page or virtual files. By taking care of these things, you should be able to get some of the space back on your SSD. But your SSD’s health is low if you are still facing this.

System Restore Points

System Restore is a feature of Windows that lets you take your machine back to a time before it was in its current state. When this option is turned on, Windows makes repair factors and saves them on your SSD.

These fixes take up room in your storage and could make your SSD work better. To free up room, you can change how System Restore works or delete unnecessary restore points by hand.

Temporary Files

Different tools and methods on your computer can be used to make temporary files. These papers are meant to be temporary, so they are often deleted. But in some cases, even short files can take up a lot of room. You can remove temporary files on your SSD with disk cleanup tools or software from a third party.

Hidden Files and Folders

Some systems hide certain system files and folders by default. These secret files are most likely taking up much space on your SSD. You could change the settings for your operating system’s document viewer to show hidden files and folders so that you could see them.

Page File or Virtual Memory

The web page report, also called “digital memory,” is a system file that the computer uses to make up for low RAM (random access memory) when running low. The page report can take up a lot of storage space on your SSD. To free up room on your SSD, you can change the size of the page record or move it to another drive.


Several factors can account for the discrepancy between the SSD’s displayed space and marketable capacity. First, the differences in measurement standards between manufacturers and operating systems play a significant role.

Operating systems calculate storage capacity using the binary machine, where 1 kilobyte equals 1,024 bytes, whereas producers use the decimal machine, where 1 kilobyte equals 1,000 bytes. This discrepancy causes the SSD’s displayed capacity to decrease slightly.

In addition, the file overhead, which consists of essential device documents, metadata, and indexes, occupies some space on the SSD. When formatting an SSD, the document system allocates a small amount of storage for these purposes, reducing the space available for user data. The choice of report device and cluster length during formatting can also affect space utilization.

Hidden machine files and partitions created by the operating system also contribute to the concept of less available space on the SSD. These files, which include the recovery partitions and virtual memory documents, are crucial to the device’s functionality but consume storage space.

In addition, certain elements can make your SSD appear complete even if no documents are present. Machine maintenance points, temporary documents produced by various computer programs, and hidden files and folders can all occupy common storage space. Adjusting device restore settings, removing unnecessary restore factors, cleaning up temporary files, and exposing hidden files and folders can help recover some SSD space.

It is important to note that if you have followed these steps and are still experiencing limited storage capacity, it may indicate a decline in SSD health. In such cases, it is advisable to consider replacing or enhancing the SSD to ensure superior performance and storage capacity.
