How to Fix SSD Health at 99% [Full Guide in 2024]

This guide will lead you to know whether SSD health at 99% is normal or not. You can get the precise tool to check SSD health quickly and easily. Furthermore, you can get some tips to maintain your SSD performance.

SSD is an essential computer storage device. For SSD, its health status determines its life span and usage performance. Therefore, it is critical to check the SSD health percentage. Many users are curious if SSD health at 99% or 98% is normal. Don't worry. EaseUS will walk you through a detailed analysis of SSD 99% health status and how to detect and maintain the health of SSDs.

Overview of SSD Health at 99%: Is It Normal?

It is a common problem for SSD health ratios to become 99% or 98%. Many users have responded on the forums that their SSDs become 99% healthy after a period of use. The following is a typical case:

Every SSD has a certain amount of data, and SSD health is usually just the amount of writes subtracted from the total and shown as %. So is SSD health at 99% normal? Let's take a look.

Is It Normal For My SSD Health at 99%

Whether SSD health at 99% is normal or not depends on the specific situation:

• For a new SSD: If it's new and the SSD health is at 99% or lower, it is not normal. A manufacturing defect may cause it.
• For a used SSD: SSD health at 99% is normal. This is only a measured countdown to warranty endurance. SSD health drops because the storage cells in a solid-state device wear out during each write operation, and each cell can only withstand a limited number of overwrites.

In summary, if the SSD health within a few months will be 99%, 98%, and 96%, this is still an excellent SSD. However, if the SSD health is dropping fast, it is time to take notice. So how do you test the SSD health? Read on to find the best way to test the health of your SSD.

FAQs About SSD Health at 99%

This section has more questions and answers about SSD Health at 99%. If you also have these questions, please read on.

1. Is 98% SSD health good?

98% or 99% health is normal for SSDs. If it is a new SSD, 98% health should be the condition after using it for almost a year.

2. Why is SSD health decreasing?

This depends largely on the construction of the SSD. It will slowly wear out every time it reads and writes data. But don't worry. It usually takes several years to be completely worn out. Some external causes, such as SSD damage and high SSD temperatures, can also cause its health to decline.

3. Should I worry about my SSD at 88% health?

The health ratio of an SSD is based on the amount of data written (TBW) since the SSD was first run. For example, if you have a 300TB SSD, 88% of the running condition has only written 36TB of data. You still have 264TB of data left, so there is no need to worry about 88% health.
