Can I restore my SanDisk Extrem SSD's performance?

“I have one 480 GB SanDisk Extreme SSD installed on a Dell desktop running Windows 7. It is fact that SSD owns better performance than HDD. But, recently, both the program loading speed and system booting speed are becoming lower and lower. It seems that the performance of SSD has gone down after being used for long time. I have formatted my SanDisk SSD, but there is much help. Should I purchase a new SSD to replace it or is there a way to recover my SanDisk Extreme SSD lost performance?”

You need to securely erase SanDisk Extreme SSD

There is no need to replace your existing SanDisk SSD with a new SSD. Have knowledge of the reason for SSD's lower performance and you will have an idea about what to do. Written cells on SSD have to be erased before new data is stored; therefore, if there are no new written cells to store new data and cells are be reused, the performance of SSD will degrade. That is to say, if you want to make SSD at original status, you need to totally erase the written cells, which is beyond the ability of format. In such a case, you can securely erase data on SanDisk Extreme SSD to reset it to factory value and restore its peak performance rather than just format SSD.

Securely erase SanDisk SSD via SanDisk SSD Dashboard

SanDisk Dashboard is a SanDisk SSD tool that can be installed on Windows Vista/7/8/8.1 (32bit or 64bit). This tool owns various functions such as “create bootable USB drive”, “Secure Erase” and “update firmware”. To make SanDisk Secure Erase, you have to download SanDisk Dashboard from official website. Then install and fire up it. When you run this application, it will automatically scan for SanDisk SSDs. Then you can do as follows:

1. Choose the corresponding SSD that you need to securely erase.

2. Choose “Secure Erase” on left panel under “Tools” menu.

3. Click “Erase Now”. Then SSD will be erased and present in the form of an unformatted space.


▪ If your SanDisk SSD is not showing up in the SanDisk SSD Dashboard, you can reconnect it and click on refresh.

▪ When your SanDisk is the boot drive, create a USB drive with SanDisk Dashboard. What I want to notice you is that the file system of USB must be FAT or FAT 32.

If so, you can make a clean install on it and put it into use. If not, you can throw up it as SSD secure Erase has deleted all the data on it permanently.
