SD cards are essential to any photographer as they’re one of the most popular types of memory cards used by camera manufacturers. There are other categories of people who could benefit from SD cards though. Anyone who needs to expand the storage capacity of various compatible devices such as laptops, gaming consoles, or scanners can take advantage of this kind of memory card. One downside of the popularity of SD cards is that the market is full of so many choices which makes picking the right option very difficult. If you’re sure you need an SD card for your particular device, there are just a few key aspects which you have to take into account before you start searching the market for suitable products:

1. Class 10 speed

If you care about writing speed, you should make the extra investment into a memory card with a Class 10 rating. This ensures a quick enough sequential write speed to handle the filming of high-resolution videos. There are other speed classes out there, but Class 10 is the fastest.

2. Capacity

This depends on your needs but it’s worth knowing that 64GB is one of the most balanced options considering the cost per gigabyte. If your needs are less demanding, 32GB cards could still represent viable options. For most users, 32GB and 64GB card varieties offer plenty of space but there are higher options too. You can go for 128GB or 256GB SD card capacities which have become quite popular. They are more expensive, but if you’re a professional, it could be worth it to be able to store more photos and recordings. Before looking at cards with larger capacities, it’s important to make sure that your device is compatible with SDXC. The ‘XC’ in this type of SD card means ‘extended capacity’.

3. Ultra High Speed Class (UHS)

Some SD cards are better designed to meet the demanding needs of those who take constant high-resolution pictures or record in Full HD. You will require a higher speed UHS card if you plan on working with very large resolutions, like recording video in 4K.

There are probably some other details that matter too when it comes to selecting the best SD memory card. Still, the features presented in the guide are the essential ones to consider. Now it’s time to check out the individual reviews of products that made this list. Only certain memory cards have been included, those that do the best job at balancing the latest technologies, performance, and design with their cost. You might also be interested in our articles about the best sd card readers and the best micro sd card.

This model comes with V30 speed class for easily capturing uninterrupted 4K videos. You’ll no longer have to worry about dropped frames when filming fast-action scenes. Another feature that contributes to this level of performance is the UHS U3 rating.

To be able to handle rapid shots and other types of high-performance photo capturing, you need a memory card that can write data fast enough. As this SD card can reach a maximum of 90Mb/s writing speed, it’s sure to increase your productivity. The read speeds are a bit higher managing approximatively 95Mb/s in the best case scenario.

In terms of storage capacity, this memory card doesn’t disappoint as it comes with 64GB. That means you can store plenty of important files, but the manufacturer offers other versions with different capacities to suit multiple needs. You can go even as low as 8GB or as high as 512GB.

A nice little extra that SanDisk provides for this SD card is the RescuePRO Deluxe software. Accidental deleting of data can happen so it’s nice to know that you can still recover files using this handy software. To start, you will need to download your free included copy.

Considering the overall features of the SanDisk Extreme Pro, it can be said that it’s worth the extra investment compared to regular SD cards. It’s a blazing fast memory card whose value per cost deserves an important spot on this list. A great tool in the hands of any demanding photographer.

Minimizing the time spent moving files from the card to your PC is a top priority for this memory card. Keep in mind that the impressive 95MB/s speed is for reading data. When you’re writing new data to the card, expect a lower value, somewhere around 50-65MB/s to be more realistic.

You can also shoot multiple frames in a second with ease if you are a photographer or record 4K UHD videos. As these could require extended storage, there are models that go beyond 32GB with the largest being 256GB.

If your work takes you to harsh environments, it’s worth mentioning that the name ‘Extreme’ of this memory card isn’t just for show. It can resist x-rays and high temperatures. Water and shocks shouldn’t pose any problems either.

6. Sony SFG2UY2/TQ 256GB Class 10 UHS-1

Sony is a familiar brand in the electronics industry, and photographers will also recognize its influence in the SD card department where they have lots of performant models available. One of them is the SFG2UY2/TQ, a 256GB model which comes with an excellent value per cost ratio.

Its large capacity is clearly one of the most impressive characteristics of this memory card. If 256GB is excessive to you, it’s worth knowing that Sony also makes this model in lower capacities while hardly making any compromises on the overall performance. The card can be found in capacities as low as 8GB and 16GB.

Before we try to understand its performance better, let’s take a closer look at the design choices. It seems that Sony focused on durability to allow you to use the card with confidence even when the environment gets difficult. Some of the key protective features of the SD card are resistance to water, dust, temperature, and UV rays. An advanced anti-static technology has also been integrated.

Performance-wise, the 256GB memory card can work pretty well considering its 70MB/s transfer speed. To be able to achieve this value you are going to need a capable interface. This level of performance is perfect for advanced shooting and combining this with the large storage capacity means you can work for longer and more efficiently.

A special downloadable software to recover files is offered by Sony to try to find those damaged or erased photos and bring them back. The File Rescue software is one of the most reliable available.

With so much space available, the Sony SFG2UY2/TQ won’t fill up too soon and when you take into account its overall reliability, the final conclusion can be highly positive. As it lacks a U3 speed rating, it won’t be a good choice for 4K recording, but for anything else, this model delivers the quality you’d expect from Sony.

  • 70 MB/s Transfer Speed

Although the 30MB/s transfer speed performance doesn’t seem that impressive, it’s actually very good if you factor in the reduced cost. The card is fully Class 10 compliant making it a good option for Full HD recording and reasonably fast high-resolution picture-capturing response.

To achieve its maximum speed, it’s required to use only devices that provide support for the UHS-I interface.
