MicroSD cards are a popular choice for expanding the storage capacity of various devices, including smartphones, cameras, gaming consoles, and single-board computers. With so many options available on the market, it can be overwhelming to choose the right one. This guide provides insights into what to look for when buying a microSD card and highlights some of the best options available.
When purchasing a microSD card, the first consideration is the storage capacity. Modern microSD cards range from 32GB to 512GB, with some models offering 1TB models. The recommended storage capacity depends on individual needs and usage. For most users, a 128GB or 256GB card is sufficient to store photos, videos, and other files. However, if additional space is needed, a 512GB card may be a better option. It is important to note that the performance of a microSD card can vary depending on the capacity. Higher capacity cards may have faster read and write speeds.
Read and write speeds are crucial factors to consider when choosing a microSD card. Read speed refers to the speed at which data can be accessed from the card, while write speed refers to the speed at which data can be written to the card. These speeds are usually measured in megabytes per second (MB/s). Sequential read and write speeds are important for tasks that require accessing or saving large amounts of data at once, such as recording videos or copying files. Random performance refers to the speed at which the card can read and write small files scattered throughout the device. This is especially important for gaming devices and single-board computers that frequently access small bits of data in random locations.
MicroSD cards are assigned speed ratings by the SD Association, which include Video Speed Class (V-rating), UHS Speed Class (U-rating), Speed Class (C-symbol), and Application Performance (A-symbol). The V-rating indicates the minimum sequential write speed and is crucial for video recording. The U-rating also indicates the minimum sequential write speed. The Speed Class rating indicates the minimum sequential write speed, while the Application Performance rating indicates the random read and write speeds. It is recommended to look for a card with V30, U3, and A2 ratings for the best blend of price and performance.
Another important consideration is the bus interface of the microSD card. Most microSD cards available today use the UHS-I interface, which has a theoretical maximum speed of 104 MB/s. There are also UHS-II cards with higher speeds, but they are generally more expensive and not necessary for most users. It is important to note that the microSD card will only be as fast as the slowest link in the chain, so it is essential to have a compatible card reader and host device to take full advantage of the card’s speed.
Warranty is another factor to consider when purchasing a microSD card. Many cards are designed to be durable and come with lifetime limited warranties. It is recommended to buy from known brands and reputable retailers to avoid counterfeit products. Running benchmark tests and using software to verify the card’s capacity and performance can help ensure the authenticity of the card.
Based on thorough research and benchmark tests, several microSD cards stand out as the best options. The Samsung Pro Plus is one of the top choices due to its fast sequential write speeds, affordability, and high ratings. The Kingston Canvas Go Plus is another strong alternative with fast sequential read speeds and a lifetime limited warranty. The Samsung Pro Ultimate is slightly faster than the Pro Plus and offers the highest sequential read speeds, but it comes at a higher cost. The Samsung Evo Select is a budget-friendly option with acceptable performance for most use cases. Other notable microSD cards include the SanDisk Extreme, SanDisk microSDXC Card for Nintendo Switch, Lexar Professional 1066x, Delkin Devices Power, and PNY Elite-X.
In conclusion, when purchasing a microSD card, it is important to consider the storage capacity, read and write speeds, speed ratings, bus interface, warranty, and authenticity. The best microSD card for each individual depends on their specific needs and usage requirements. The recommended options include the Samsung Pro Plus, Kingston Canvas Go Plus, Samsung Pro Ultimate, Samsung Evo Select, and several others. By understanding the key factors and considering personal preferences, users can make an informed decision and choose the best microSD card for their devices.
