How Long Does A Solid-State Drive Last

From large enterprises to small businesses to managed services providers (MSPs), storage needs across a wide range of industries are surging. In fact, an IDC report states we can expect the total size of worldwide data to grow 61% by 2025, when it will hit 175 zettabytes. As companies grapple with these daunting storage requirements, they will need to consider a diverse array of options to boost performance and use their resources as effectively as possible.

How long does a SSD last?

SSDs are fairly new to the market, meaning manufacturers are still trying to figure out how long they will last. Currently, vendors use three different factors to estimate SSD lifespan: the age of the SSD, the total number of terabytes written over time (TBW), and the drive writes per day (DWPD). Based on which metric you use, the answer to the question “How long do SSDs last?” will vary.

For example, the age of an SSD has proven to be a valuable determinate in its performance and longevity. Current estimates put the age limit for SSDs around 10 years, though the average SSD lifespan is shorter. In fact, a joint study between Google and the University of Toronto tested SSDs over a multi-year period. During that study, they found the age of an SSD was the primary determinant of when it stopped working. Researchers working on the study also found SSDs were replaced about 25% less often than HDDs.

How to measure the lifespan of a SSD?

Another way of measuring how long SSDs will last is the total number of terabytes written over time (TBW). TBW estimates how many successful writes you can expect a drive to make over its lifetime. If a manufacturer says their SSD has a TBW of 150, it means the drive can write 150 terabytes of data. After the drive hits that threshold, it’s likely you’ll need to replace it.

The final of the three metrics manufacturers might use when predicting the lifespan of their drives is the drive writes per day (DWPD). DWPD measures how many times users can overwrite the amount of available storage in the drive each day of its working lifespan. If an SSD has a capacity of 200 GB and comes with a five-year warranty, for instance, users can write 200 GB onto the drive every day for the warranty period before it fails. When in doubt, you can use an online SSD lifespan calculator to estimate the SSD’s lifespan.
