As solid state drives (SSDs) become cheaper, many consumers will choose SSDs when replacing or upgrading PC and laptop hardware since SSD performance is much better than traditional hard drives (HDDs). These SSDs are inevitably replaced by even faster SSDs. This article will discuss how to properly dispose of old SSDs at a time when information security risks are becoming more and more prevalent. Whether personal privacy, videos, passwords, or business secrets, you do not want your information stolen after replacing an SSD. Thus, you need to consider how to safely clear SSD data.

The structure of an SSD is completely different from that of a HDD. HDDs rely on magnetic materials to store data on rotating disks, while SSDs use flash memory technology to store data in fixed storage blocks. SSDs employ an important technology called wear-leveling which evenly distributes the load of data writing throughout the storage block to prevent excessive wear of specific blocks. In addition, there are technologies such as block-sparing and SLC caching, all of which are used to extend the life of the SSD and improve reliability and durability.

What’s the difference between how SSD and HDD store data

Many people mistakenly believe that deleting data or formatting a hard drive means that data will be permanently erased. However, these actions only indicate that the marked memory block in flash memory can be rewritten with data. In fact, the data still exists on the SSD and can be recovered using professional tools. Conversely, erasing data uses a variety of technical means to ensure that data cannot be recovered and permanent erasure achieved.

What is data erasure of SSD and HDD

Here are several ways to erase data for your reference.
1. Use drive erasure software (such as SSD Toolbox) to perform "secure erasure."
2. Use a hardware erasure device (depending on whether the SSD supports H.W. Security functionality).
3. Physically destroy the device.
"Securely Erase Drive" refers to the process of completely erasing all data on the drive so that deleted data cannot be recovered, even those blocks that have been reallocated due to wear-leveling. Therefore, before erasing SSD data, please remember to create a backup. There are a variety of secure erasure software tools on the market. This article introduces how&nbsp;<a href="https://www.adata.com/en/support/downloads/" target="_blank" rel="noopener">ADATA SSD Toolbox</a>&nbsp;can be used to easily erase data.
1. Open <a href="https://www.adata.com/en/support/downloads/" target="_blank" rel="noopener">ADATA SSD Toolbox</a>, click the Utility item on the left menu to perform Security Erase and please read the message prompt carefully.

Several methods for secure data erasure

2.&nbsp;Once you click Start, you will be prompted again that all data will be removed.

3.&nbsp;You must confirm this operation a second time because, once data is securely erased, it cannot be recovered.

4.&nbsp;The Security Erase Complete message box pops up, indicating that all data in this SSD has been completely erased and returned to factory specifications.

Finally, if you still have doubts regarding the secure erasure process, the only remedy is to physically destroy the Flash IC components inside the SSD.
