SSDs have replaced the older HDDs as the standard storage component in devices like laptops and consoles, and it’s easy to see why. They are faster and more reliable because they do not rely on mechanical components such as spinning disks or spindles and instead use chip-based NAND technology. This makes them more reliable for a longer period of time, although you still need to take measures to protect your SSDs from sudden data loss.
However, nothing lasts forever and SSDs, like old flash drives, have a limited lifespan and eventually die. This means you need to manage the health of your SSD to track its performance and take precautions to protect your data when that day comes. It’s also worth knowing how SSDs work and what their expiration date is, so you can make the right purchase decision and never have to stress about data loss. Here’s the overview of your SSD’s expiration date and ways to keep it in tip-top condition for longer.
What is NAND memory?
Chip-based data storage
You need to know how NAND memory works to understand why SSDs have an expiration date. Older HDDS stored data on magnetic media, but SSDs use NAND chips instead. Each chip contains billions of tiny cells that hold an electrical charge. To work, SSDs push electrons into a cell, where they are trapped behind an insulating barrier and stored for later use. In simple terms, your data is stored as trapped electrons in the cells.
These cells eventually degrade with frequent erasures and rewrites until they can no longer hold a charge. That’s why modern SSDs include built-in controllers that manage wear and fix smaller issues to extend its lifespan.
How long will my SSD last?
Many variables to consider
It’s hard to say because every SSD is different and will experience different wear and tear depending on how it’s used. Most SSDs should last about five to ten years of regular use and withstand about 20 to 40GB of data transfer per day. Reputable brands include various metrics on their SSDs to provide an idea of their durability. Here are two of the common metrics used to determine your SSD lifespan.
Terabytes Written (TBW): This is the total amount of data that can be written on the SSD in its entire life before its performance suffers. For example, Samsung’s 4TB Evo Plus has a TBW rating of 2,400. It means that the drive can write up to 2,400 terabytes in its lifetime with regular use.
Reputable brands include various metrics on their SSDs to provide an idea of their durability.
Mean time between failures (MTBF): This is measured in hours and is an estimate of the average uptime without failure across many drives. For example, the same Samsung 4TB Evo Plus has a 1.5 million hour MTBF rating, which in theory means it can run for many years without problems. However, it is worth taking this rating with a pinch of salt as it is based on estimates and does not reflect guaranteed performance.
Most SSDs from quality brands show these ratings. You also get a manufacturer’s warranty, measured in years, as a guarantee of its build quality and durability. Keep in mind that SSDs vary in quality, and you’ll get better life from an enterprise-grade model than from budget-friendly options.
How can I extend my SSDs life?
Basic housekeeping tips
Now that you know how SSDs work, you need to follow some best practices to ensure that yours performs at its best. These are some basic maintenance tips to keep your SSD in top condition.
Use the software to monitor his heather: Most SSDs include bundled software, such as the Kingston SSD Manager or Western Digital SSD Dashboard. It is recommended that you use these apps to monitor your SSD health and keep the firmware up to date. Then you will be able to know when your SSD has problems and recover your data before it is lost.
Always have free space on your SSD: SSDs perform better and last longer when they have at least 10 to 20% free space. This is because they use that extra space for essential functions, such as wear level, which stores data evenly across the SSD, so that some cells don’t wear out faster than others.
These are some basic maintenance tips to keep your SSD in top condition.
Power the SSD regularly: This does not apply to the SSDs that you regularly use in your PC or console and is for those that you have saved for backups and data storage. Open it at least once every three to six months to refresh the load and scan for data errors.
Store your SSD in a safe place: This is the easiest of them all. Store your SSDs in a cool, dry place and keep them away from moisture. Also keep them away from magnets and ensure that they do not operate in extremely hot or cold environments.
Backup your data: Remember, most SSDs have an approximate 5 to 10 year lifespan which can go higher or lower depending on many factors. It is not worth taking chances and always backing up your data in different places to keep it safe.
