What is the difference between an in-car SD card and a regular SD card?
2 Answers
Below is a related introduction to the differences between in-car SD cards and regular SD cards: 1. Regular SD: Memory cards refer to storage cards used for storing entertainment content. Navigation devices generally use large cards called SD cards, while most small cards are called MiniSD cards, used in mobile phones. Mobile phones typically use TF cards, also known as micro-SD cards. SD cards are commonly used in cameras, and TF cards can also be inserted into SD card adapters to function as SD cards. 2. In-car SD: Among the two types of cards commonly used in cars, the navigation card and memory card may look similar in appearance but differ in nature. Car navigation cards are divided into SD cards and MiniSD cards. Generally, mobile phones support MiniSD cards, while navigation cards are SD cards, which are usually not suitable for mobile phones. There is also a MiniSD to SD card slot adapter, allowing mobile phone cards to be used in cars. However, it is more convenient to simply download a mobile navigation app, which is also easier to upgrade.
In-vehicle SD cards differ from regular SD cards mainly in durability. I often drive long distances, and the temperature inside the car varies greatly—it can get as hot as 50-60°C in summer. A regular card would fail after being exposed to such heat a few times. In-vehicle SD cards are specifically designed to withstand high temperatures, with more durable materials and better shockproof design, ensuring stable data transmission even on bumpy roads. A regular card used in a dashcam might develop poor contact within a month, causing intermittent recording. In-vehicle SD cards last longer, and while they are more expensive, they save you the hassle. In terms of capacity, they are similar, but some older car systems may not support high-capacity cards, so check the manual to confirm the maximum supported capacity before purchasing.
