- SD card A2 cards have a higher minimum sustained write speed and a higher minimum random read speed than SD card U3 cards.
When it comes to choosing an SD card, there are two main types you’ll encounter: A2 and U3. Both offer fast performance, but there are some key differences between the two. In this blog post, we’ll take a closer look at SD card A2 vs U3 and help you decide which one is the better choice for your needs.
What is SD Card A2?
SD card A2 is a new class of SD cards that was introduced in 2019. It is designed for use in applications that require fast random read and write speeds, such as 4K video recording, gaming, and app loading. SD card A2 cards have a minimum sustained write speed of 10MB/s and a minimum random read speed of 4000 IOPS.
What is SD Card U3?
SD card U3 is an older class of SD cards that was introduced in 2013. It is also designed for use in applications that require fast performance, but it has a lower minimum sustained write speed than SD card A2 cards. SD card U3 cards have a minimum sustained write speed of 30MB/s and a minimum random read speed of 1000 IOPS.
SD Card A2 vs U3: Which is Faster?
In terms of raw speed, SD card A2 cards are faster than SD card U3 cards. This is because SD card A2 cards have a higher minimum sustained write speed and a higher minimum random read speed. This makes SD card A2 cards a better choice for applications that require fast random read and write speeds, such as 4K video recording, gaming, and app loading.
SD Card A2 vs U3: Which is More Expensive?
SD card A2 cards are typically more expensive than SD card U3 cards. This is because SD card A2 cards are newer and offer faster performance. However, the price difference between SD card A2 and SD card U3 cards is narrowing, and you can now find SD card A2 cards for a reasonable price.
SD Card A2 vs U3: Which is Better for 4K Video Recording?
If you’re planning on using your SD card for 4K video recording, then you’ll need an SD card with a high sustained write speed. This is because 4K video files are very large and require a fast write speed to avoid dropped frames. SD card A2 cards are a better choice for 4K video recording than SD card U3 cards because they have a higher minimum sustained write speed.
SD Card A2 vs U3: Which is Better for Gaming?
If you’re planning on using your SD card for gaming, then you’ll need an SD card with fast random read and write speeds. This is because games often load large amounts of data from the SD card, and a slow SD card can cause lag and stuttering. SD card A2 cards are a better choice for gaming than SD card U3 cards because they have faster random read and write speeds.
SD Card A2 vs U3: Which is Better for App Loading?
If you’re planning on using your SD card for app loading, then you’ll need an SD card with fast random read speeds. This is because apps often load small amounts of data from the SD card, and a slow SD card can cause apps to load slowly. SD card A2 cards are a better choice for app loading than SD card U3 cards because they have faster random read speeds.
The Verdict: SD Card A2 vs U3
So, which SD card is the better choice? It depends on your needs. If you need an SD card for 4K video recording, gaming, or app loading, then you should choose an SD card A2 card. If you need an SD card for less demanding applications, such as music playback or photo storage, then you can choose an SD card U3 card.
