How to Calculate the Lifespan of Your SSD and Hard Drive

It’s important to understand that both hard drives (HDDs) and solid-state drives (SSDs) have a limited lifespan. This is more noticeable with SSDs because their lifespan is tied to the number of write cycles they can handle.

While SSDs are faster, smaller, and more efficient, this limitation is a downside. On the other hand, hard drives (HDDs) also have a set lifespan, but it’s more dependent on how long they’ve been in use and the number of hours they run.

If you’re curious about how much longer your drives might last, keep reading—we’ll explain it in detail.

Average Lifespan of an SSD

As mentioned earlier, the lifespan of an SSD is determined by the number of times data is written to it, since there’s a limit. Once that limit is reached, the SSD will eventually switch to a read-only mode.

This happens because of how SSDs are built. While they offer much faster speeds compared to traditional drives, the trade-off is a shorter lifespan.

However, the average user won’t need to worry about reaching this limit anytime soon. In fact, it could take several years for most people to use up all the write cycles on an SSD.

If you’re curious about how much time your SSD has left, it’s worth knowing that modern SSDs typically last for about 700 TB of written data over their lifetime.

Of course, this number is just an estimate. Your SSD could last longer or shorter, but it’s a good reference point to keep in mind.

Average Lifespan of an HDD

The lifespan of a HDD is not measured the same way as an SSD. Instead of counting the number of write cycles, the life of an HDD is estimated based on the number of hours it operates, similar to how other devices are measured.

On average, a typical hard drive can last around 20,000 hours of use. However, this is just an estimate—some drives may last longer, while others might not reach this limit.

This doesn’t mean the hard drive will suddenly stop working after hitting 20,000 hours. You’ll likely notice signs of wear and tear before that, such as an increase in corrupted files, unusual noises, slow performance, or even power issues.

Estimating Durability

To check how your SSD or HDD is holding up, you can use a program like CrystalDiskInfo, which is free and open-source.

While it won’t tell you exactly how much time your drive has left, it will give you an idea of its current health, helping you decide what steps to take.

Once you download and install CrystalDiskInfo, simply run the program and check the Health Status of your drive:

• If it says Good, there’s no need to worry; your SSD or HDD is in great condition.
• If it shows Caution, this means your drive is starting to degrade. It’s a good idea to back up your files, and you might want to think about replacing the drive soon, though it’s not urgent.
• If it says Bad, your drive is nearing the end of its life. You should replace it as soon as possible to avoid losing data.

For SSDs, you can also check the Total Host Writes (located in the top right corner), which tells you how much data has been written to the drive so far.

If you’re looking at an HDD, pay attention to the Hours On value, which indicates how long the drive has been in use. By comparing this to the average lifespan we discussed earlier, you’ll get an idea of how much longer it might last.

Trick to Estimate the Lifespan of an SSD

There’s a simple trick you can use to get a more realistic estimate of how long your SSD might last.

You can rely on the warranty information provided by the manufacturer when you bought the SSD. While this doesn’t guarantee the exact lifespan, it can give you a good idea of what to expect.

For example, if your SSD comes with a 5-year warranty or a 600 TB Total Host Writes (TBW), it will likely last around that period or amount of data written. Similarly, if the warranty states 3 years or 200 TB TBW, you can expect it to last close to those limits.

With this information, along with what we’ve covered so far, you should now have a better understanding of how to estimate the remaining lifespan of both your SSD and HDD.
