How can you securely delete information from a hard drive or an SSD?

If you want to securely delete information from a SSD, then there are some things that you need to know.

– SSDs use something called blocks and pages to store data and these two components work together to determine how quickly the SSD can write new data.

If you overwrite a block that is already mapped out by an existing file, then the SSD is not going to be able to simply overwrite that block with the new information, but rather it has to move all of the existing information on top of a different block in order for it to be able to write the new data.

– When SSD manufacturers talk about how long an SSD will last they are not taking into consideration how many times you have been overwriting data from one singular block, because due to how SSD technology works when you overwrite a block that is already mapped out, then your SSD is going to experience a decrease in performance until you actually clear out some space by writing over other blocks with real data.

With this being said you should simply go ahead and use a secure erase tool in order to get rid of any information that you no longer need.

– A secure erase tool basically retraces all of the blocks on an SSD in order for it to be able to delete all of the data from those blocks. If you want to securely delete information from SSD, then a secure erase tool is the only way to go.

This allows SSD manufacturer specifications about how long SSD will last as false as possible as you can overwrite blocks that have been already mapped out by files, making SSD performance decrease.  In order to avoid this outcome just buy an SSD drive and use a secure erase tool any time you need to delete information from SSD.

EaseUS is one of them it’s recommended that you use a secure erase tool in order to make sure all of your data is gone for good.  

If you don’t want to take the time to actually learn how SSD technology works and how it makes SSD securely erase information, then buying an SSD is not going to be worth your money because there are so many SSD manufacturers on the market today and some SSD manufacturers offer SSD drives that might be cheaper than other SSD drives, but they offer less capacity and will result in you having to buy another SSD drive very soon if you plan on keeping your computer for over 5 years.

SSD performanec Decrease

An overprovisioned SSD does not show signs of poor performance until the SSD has gone through several hundred thousand erase cycles, which can take years to occur, but you will eventually notice that SSD performance is being affected because of information on SSD blocks is not being erased.

This does not mean you have to go out and buy a new SSD drive so quickly though because if you do some research on SSD technology then you will see that there are SSD manufacturers with SSD drives that allow you to disable blocks on your SSD in order for it to be able to speed up the performance again.  

If you do this then just don’t forget how many times or how long ago was the last time that you had written over a block before enabling it again because there is nothing worse than SSD performance is so poor that you have to spend up to a week waiting for SSD information deleted.

– You can do this by going to the SSD manufacturer’s website and checking their track record of SSD drives, but it does cost money in order to get an SSD drive with a longer warranty and better SSD technology because SSD makers spend more money on research and development than they do on advertising, making some SSD drives very expensive even though you are just buying a storage device.  

In the end, if you want to securely delete information from SSD you just need to go out there and buy an SSD drive with high speeds like 400 MB/s or one that allows you to disable blocks in order for your SSD to be able to perform better while SSD manufacturer specifications about how long SSD will last as false.
