With increasing storage capacity and decreasing costs, solid-state drives (SSDs) are rapidly becoming the preferred choice for many users. However, when it comes to secure file erasure on an SSD, conventional methods may not be effective. Everything is retrievable and if you want to know how to permanently delete files from SSD, you will need to read what we have to say here.

Conventional Data Deletion Methods

In simple terms, deleting files using conventional methods only makes them invisible to your operating system. However, this doesn't actually erase the data itself. Here is what happens when any of the following three deletion methods:

• Send to recycle bin: Sending a file or folder to the recycle bin is not an effective way of permanently erasing it from an SSD. When you right-click on a file and choose 'send to recycle bin', your operating system merely stores the files in a designated area until they're manually deleted.
• Delete button: The 'delete' button on your keyboard serves the same purpose as sending something to the recycle bin - it merely moves the file or folder into storage, waiting for manual deletion.
• Shift + Delete: Compared to the other two methods, this one may seem more permanent, especially for those unfamiliar with data recovery software. However, even after using it and no longer accessing your file, its presence remains on the SSD until that specific memory block is overwritten by new data - a process that can take an extremely long time.

The key point to understand here is that none of these conventional methods can actually erase files from an SSD in a way that makes them permanently unrecoverable. With some basic knowledge or specialized data recovery software, it becomes possible to retrieve deleted files.

Data Deletion – SSD vs HDD

When it comes to deleting data, hard disk drives (HDDs) and solid-state drives (SSDs) use fundamentally different approaches due to their distinct architectures. In HDDs, data is stored in sectors, but the HDD can write over used areas of the disk whenever it wants. When you delete a file, the HDD removes that file from its tables and that is it. Anyone could retrieve that data by using recovery software.

In contrast, SSDs work in a completely different style. SSD storage consists of blocks and these blocks carry data in the form of digital signals. Whenever you delete data, the SSD removes the data from its tables but if a certain block contains both deleted data and something that you want to retain, the deleted data will remain accessible. This means that you do not have the ability to remove it until the whole block is empty.

How to TRIM Command to Delete Files on SSD

To ensure that permanently deleted data no longer resides on an SSD, the controller employs a feature called TRIM, which manages all stored data and optimizes its organization. TRIM ensures that deleted data is marked as available space, allowing it to be securely erased when needed. However, this process only occurs when the entire block containing the deleted file is cleared - if multiple items are stored in a single block and not all of them are intended for deletion, TRIM merely flags those files for future erasure.

How to Securely Erase Files on SSD

The most secure way to eliminate sensitive information is by utilizing file shredding software, like Qiling File Shredder, which irreversibly destroys data on an SSD. It comes with the following features:

Using the best file eraser tool is extremely easy and you can securely delete files on SSD with it permanently in just three steps.

1. Open the software and click the large "+" button in the middle to permanently delete files from hard drive.

2. You will see a file explorer option. Select the specific folder/partition/drive that you want to delete. Click the "Shred Now" button on the bottom right to start the deleting process.

3. Progress will show on the screen as the data is being shredded and deleted. Close the program when done, or start over again if you want to delete more data.

While deleting files from an SSD may seem straightforward, conventional methods are not sufficient for secure file erasure. To do it, you have to depend on professional File Shredder software. Download the software to have a try now!!!
