Buying Guide For The Best SD Card For Camera 2021

Let us now take a look at the features you will need in the best sd card for 4k video recording.

Type: There are three types of cards that are mainstream. They are SD, SDHC, and SDXC. You might also stumble upon memory cards like CFast cards. The SD stands for ‘Secure Digital’. They were the pioneer who set the standards for modern memory cards. You can still use them but you won’t get the performance of modern devices as use old technologies.

The term SDHC stands for ‘Secure Digital High Capacity’ and SDXC stands for ‘Secure Digital Extended Capacity’. These memory cards utilize modern technologies and offer a capacity between 4GB to 1TB. The microSDHC and microSDXC offer the same performance on a much smaller form factor to use on smartphones. The CFast cards offer better speed than SD variants but only a handful of devices support these types of cards. I would recommend using SDXC variants with more than 64GB capacity.

Capacity: Though the capacity range depends on the card variants, there are enough variations within those ranges. Depending on frame rates, compression, and device configurations the size of videos also varies. For example, one minute 4K footage taken from an iPhone won’t be equal in size when compared to a camera.

An one minute of 4K video can be from 80MB to more than 350MB. For this reason, it would be best if you check out first how much space your device needs when recording footage of a single minute. It will give you a rough estimate of the optimal size that would suit you. My recommendation in this regard would be to pick the card of the largest size supported by your device.

Form-factor: As more devices are now supporting 4K resolution, choosing the right form factor has become more important than ever. There are no alternatives to a microSDXC card if you are going to shoot videos with your phone. Due to the size of 4K video data, go with as big a capacity as possible.

On the other hand, camcorders and cameras sometimes support multiple types of cards. If your device supports cards like CFast, Cfexpress or XQD then go for those. You will get to enjoy superior performance than regular SD cards, but their support is limited and the cost is much higher. In case those cards are not supported, then the obvious choice would be SD card variants.

Speed: Speed is a big factor when copying stuff on and off the device. As 4K video recordings tend to be rather large, you should pay attention to this trait of a memory card. Speed is also essential when recording the footage at a super high quality. If the card can not keep up with the device’s writing rate, you might get broken clips.

As most cards today can handle the recording speed of a device pretty well, it is the moving speed of data that matters most. A writing speed of ~90MB/sec would be decent enough to provide you a smooth experience.

ECC: The term ECC stands for ‘Error Correcting Code’. It is an advanced feature that is available on some memory cards. When converting the footage to binary bits many factors can cause little too big effects. Enough altered bits might ruin the little details.

I would heavily suggest picking a memory card that offers this feature if you are using it for professional work. These cards might cost a bit more, but you will have the peace of mind knowing every bit of detail will be placed on the card in a precise manner.

Durability: Durability is often the most forgotten factor when buying a memory card. The way life would much easier if the card can resist magnet, x-ray, water, shock, and whatnot. Because once they are out of the device these cards might have to face all kinds of day to day situations. And, there is no point in losing data on a minor accident.

A Few Maintenance Tips For SD Memory Cards

There are a few things to keep in mind to make the memory card last long. Follow these steps closely and you won’t need another card for a long time.

  • Format the memory card from within the camera. So, it will be fully prepared to work with your device.
  • Don’t switch the card between several devices, especially if they are the camera. It might cause malfunction.
  • Check the remaining capacity frequently. Going beyond the capacity might corrupt the data that’s already there.
  • Take extra care of the card from water, magnetic field, and shock. If it gets wet, just let it dry for a few days and check if it works properly.

Determining Which Size Fits You Best

If you ever got confused that what size SD card for 4k video would be the best, let me explain. As the proverb goes ‘waste not, want not’, there is no point overcompensating for a memory card if you don’t plan to reach its full potential. If you are a casual user you probably would not need more than 128GB.

For professional works, you will need to take a lot of clips. I would suggest getting at least 128GB. There are options for 256GB, 512GB, and 1TB if you need more.
