Your average solid-state disk (SSD), will be able to last for many years under normal circumstances. Other components, such as your CPU or GPU, will be replaced long before the SSD fails.
The biggest worry (aside price) when flash storage was introduced to consumers as an option to traditional hard drives was its longevity. Although tech enthusiasts had an excellent idea about the reliability of hard drives in general, solid-state drives (SSDs), were still a mystery.

Unveiling the Fundamentals of SSD Lifespan
The market for SSDs is now mature and there’s a lot of data about data. SSDs are extremely reliable, and at least as efficient as hard drives when it comes to data retention and failure rate. Unfortunately, SSDs fail more frequently with age than with longer data writing.
This means you are less likely to lose your data with an all flash setup than with a regular hard drive. However, it is still important to have a backup of any vital files .
It’s important that we have a basic understanding of some terms related to SSDs before proceeding to the actual testing:
- SLC and Multi-level Cell memory, which is generally available on consumer-grade SSDs, are cheaper and more efficient than the faster SSD drives. The single-level cell memory found in enthusiast and enterprise-grade SSDs are faster and less likely to lose data.
- Memory block is a portion of the flash drive’s physical memory. Bad blocks are inaccessible to the computer or not accessible at all. This can lead to lower storage levels and possible write and read errors.
- TBW Terabytes written. This is Terabytes, the total data that has been written to and rewritten to drives over their lifetime.
Let’s now answer the question with that knowledge.
What’s the Average Lifespan of an SSD?
A typical SSD can withstand many years of normal home usage before it becomes seriously damaged. The drive’s data, age and ambient conditions will all affect how long the SSD lasts. According to our Experience, no SSD has ever died on them — even though we put way more mileage on our computers than most people. What data can we find out about the longevity of your new SSD?
The reliability of SSDs is often rated on the basis of three things: the standard age of the drives (like any warranty), the total Terabytes of data that was written over the time and how much data has been written to the drive in a specific time period, such as a day. These three standards can yield different results depending on the methodology. The fact that these three standards are very loose for measuring “wear” on digital components should be enough to show the user something: it is almost impossible to predict how long an SSD will fail. The maximum data retention point that can be given is only a rough estimate. After which, the drive could cause immediate data loss.
An app called CrystalDiskInfo can monitor the health of your SSD. This app will display the number of writes to your SSD over its lifetime and provide you with an indication as to how close you are from the manufacturer’s TBW rating (Terabytes Written).
Exploring the Latest Research on SSD Lifespan
Many studies have attempted to establish a longer lifespan of solid-state memories. Some of the most well-known are:
Google and University of Toronto collaborated in a study to examine the rate of data server drive failures. According to the study, the primary determinant of whether data retention errors will occur is how old the SSD is. This was not due to the frequency or amount of data being written. The study also found that SSD drives were replaced in Google data centers less frequently than traditional hard drives at a ratio of about one to four. However, SSDs were not all good news. They experienced more uncorrectable errors than normal hard drives and had to be replaced at an even higher rate over the 4-year test period. Conclusion SSDs are more likely to fail in high-stress environments that require fast reading. SSDs older than TBW and DWPD are less likely to fail completely.
On a different note was found,
Only the Corsair, Samsung and Kingston high-end SSDs survived after writing more than 1000 petabytes (1000 terabytes) of data. Other drives crashed at 700 to 900 TBW. The failed drives were Samsung and Intel. However, the Kingston drive was the exact same model that the one that survived. Its failures occurred using the MLC standard. Conclusion A 250GB SSD should be dead within a few hours. Although two or three of these models were able to exceed that limit, you can still plan for a contingency in the event your drive fails, even though it may use more costly SLC memory.
SSDs with larger capacities should be able to last for longer periods of time due to the fact that they have more sectors available and can use more data before it fails. If a 250GB Samsung 810 MLC drive fails at 900TBW, it is reasonable to assume that a 1TB SSD drive will last significantly longer.
Facebook published a report, including a link to a PDF file. It revealed an internal study about the life expectancy of solid-state drives.
These findings focused on environmental conditions in the data center itself. For example, extended exposure to heat can be detrimental to SSD lifespans. The study found that SSDs are more likely to survive than software-diagnostic software that is too cautious. Facebook’s study found that data read and write rates have a significant impact on the life expectancy of drives. However, it’s not clear whether this was controlling for physical age. Conclusion: SSDs will last much longer than expected, except in the case of an early total failure. Software measurement of data vectors such as TDW is likely to overstate their usefulness due to system-level buffering.
All of these studies focus on datacenter intensive applications. This level of usage is not possible for the average homeowner.
Backblaze, is a cloud storage company offering computer backup and server backup services. Backblaze has conducted a study that compares solid-state drives (SSDs) and hard disk drives (HDDs) as boot drives for their servers.
This is close to what the average user may put on their drives. The study that they conducted is very simple. How many boots drives fail each year? How many HDDs and SSDs fail annually? Conclusion: HDDs and SSDs die at the same rate the first three years. However, after this period, failure rates for HDDs start to rise rapidly, while SSDs’ failure rate remains relatively constant for at most 5 years. It is unclear if SSDs will reach a “failure threshold”, an age when many drives spontaneously stop working, but you can probably count on your SSD to work for at least five years.
Why You Can Trust Your SSD: Dispelling Concerns and Assumptions
What conclusion is possible if we take all this information into account? You might worry that your SSD could burst after just a few years if you look at all of these data simultaneously. Keep in mind that two studies focused on data centers of enterprise quality, where data was written and read almost continuously for many years. The consumer study, however, was designed to stress-test drives under constant load. To reach 1 petabyte, the consumer must use their computer continuously for at least 10 years, possibly even more, to achieve this level of data. The warranty limits the data that can be written to a drive by gamers and other “power users”. Backblaze’s analysis is more positive and shows that most drives in their portfolio are still performing well after being used professionally for five years.
Also, your whole computer will be upgraded before the SSD goes bad.
It is still possible that your SSD’s electronic parts can fail. The likelihood that your SSD will experience a data loss occurs the more it is used. It’s a good idea to back up your important data to an external drive, and if you can, to remote locations. If you use your SSD for long-term storage, make sure to always plug it in. Don’t be concerned if your SSD fails at any time or is less reliable than your old hard drive.
In conclusion, technology continues to shape our world in profound ways, revolutionizing how we live, work, and interact with one another. As we move forward into an increasingly digital future, it’s important to stay informed and engaged with the latest developments in our website “Fond of Tech”, as well as our reliable sources .
