Extreme temperatures, humidity, and physical stress can all take a toll on your SD card’s lifespan. Avoid exposing your SD card to temperatures above 85°C (185°F) or below -25°C (-13°F), as this can cause data corruption and damage to the card.
Also, keep your SD card away from physical stress, such as bending, flexing, or crushing, as this can cause mechanical failure.
Write Cycles and SD Card Lifespan
One of the most common causes of SD card failure is the limited number of write cycles it can handle. A write cycle refers to the process of writing data to the SD card and then erasing it.
What is a Write Cycle?
A write cycle is the process of writing data to a memory cell on the SD card and then erasing it to make room for new data. Each memory cell on an SD card has a limited number of write cycles it can handle before it becomes unreliable.
Typically, an SD card can handle around 3,000 to 5,000 write cycles per memory cell, depending on the quality of the card.
How Write Cycles Affect SD Card Lifespan
The number of write cycles an SD card can handle directly affects its lifespan. If you use your SD card extensively, it will naturally have a shorter lifespan than one that is used occasionally.
A high-quality SD card can last for around 10 years or more with moderate usage, while a low-quality one may last for only a few years.
SD Card Capacity and Lifespan
The capacity of an SD card also plays a role in determining its lifespan. Larger capacity SD cards tend to have a shorter lifespan than smaller ones, as they have more memory cells that can wear out faster.
Larger Capacity SD Cards
Larger capacity SD cards, such as 128GB or 256GB, have more memory cells that can wear out faster. This means they may have a shorter lifespan than smaller capacity SD cards, such as 16GB or 32GB.
However, modern SD cards use advanced technology, such as multi-level cell (MLC) or tri-level cell (TLC) NAND flash, to increase storage capacity while reducing wear and tear.
