SD Card: Ten Great Picks for Small Businesses

  • by

Short for Secure Digital, SD cards are a reliable flash memory used in many different digital products. From cameras and smartphones to tablets, audio/video players, and video game consoles, SD cards have multiple applications. The best SD card for business use will depend on what you need it for, but it is fair to say there is a card out there for your use case. And this is because the technology of SD cards keeps evolving.

Since they were first introduced in 1999, the technology has evolved to now have terabyte capabilities. This is a huge leap from the 32 and 64 MB SD cards first available in the first quarter of 2000. New manufacturing processes and performance classifications now make SD cards one of the best portable storage solutions.

Choosing the Right SD Card

When it comes to businesses or professional work, the demand for SD cards goes beyond just storing personal memories. For entrepreneurs, photographers, videographers, or any professional requiring data storage, choosing the right SD card is crucial for performance and efficiency. Here’s an expanded understanding to aid in the selection process:

Performance Needs:

Speed Class: Beyond just the read and write speeds, pay attention to the Speed Class marked on the card. SD cards are categorized into classes like Class 10, UHS-1, UHS-3, etc., that indicate the minimum sustained write speed.
Sequential vs. Random Speed: While the previously mentioned speeds often refer to sequential read/write, random read/write speeds are equally important, especially for apps and OS functions.

Versatility in Applications:

Multiple Devices: If your business involves using different devices, look for cards with versatility. An SD card that works seamlessly across cameras, drones, and other recording devices offers an edge.
File Recovery Features: Some SD cards come with built-in software for file recovery, which can be a lifesaver if something goes awry.


While it’s tempting to settle for what you need today, consider future needs. With technology rapidly evolving, getting an SD card with slightly higher specifications can make it more useful down the line.

Value for Money:

Often, businesses focus on getting the most cost-effective solutions. But, when it comes to SD cards, a slightly higher initial investment can ensure better reliability and longevity, providing better value over time.

Tips for a Wise Purchase:

Always buy from authorized dealers to avoid counterfeit products.
Regularly backup data to reduce risks associated with data loss.
Keep the card’s environment in mind; some are resistant to water, shock, and X-rays, ensuring data protection in challenging scenarios.

Types of SD Cards

A quick look at an SD card and you will see different acronyms and ratings. This information is crucial to get the most out of your SD memory cards.

SD or SDSC – Secure Digital Standard Capacity: maximum of 2 GB storage
SDHC – Secure Digital High Capacity: from 2 to 32 GB of storage
SDXC – Secure Digital Extended Capacity: from 32 GB to 2 TB of storage
SDUC – Secure Digital Ultra Capacity: from 2 to 128 TB of storage

There is one more standard or type called SDIO or Secure Digital Input Output. These cards have more functionality including wireless networking such as Bluetooth or GPS receiver, television tuning, and even fingerprint recognition.


What makes an SD card suitable for business use as opposed to personal use?

SD cards designed for business use often prioritize factors like higher read and write speeds, durability, and data protection features. Given that businesses may frequently transfer large files or rely on faster data access, cards with superior speed classes, such as UHS-3, might be preferred. Additionally, cards for business use often have enhanced durability features, such as water, shock, and X-ray resistance. Some also come with encryption features for added data security, which is crucial for sensitive business data.

Is there a significant difference between microSD and standard SD cards for business applications?

Both microSD and standard SD cards serve the primary function of data storage. The main difference is their size, with microSD cards being much smaller. The choice between them largely depends on the devices being used in the business. In terms of performance, both can offer high read and write speeds, especially if they are from reputable manufacturers. It’s essential to ensure that the chosen card type is compatible with the business’s devices and meets the required performance standards.

How often should businesses replace or upgrade their SD cards?

The need to replace or upgrade SD cards can vary based on the frequency and intensity of use. Typically, under normal conditions, SD cards have a lifespan of about 10 years, as mentioned by the SD Card Association. However, for businesses that constantly record, overwrite, or access data, this lifespan can be shorter. Regularly monitoring the card’s performance and checking for signs of slowing down or errors can provide an indication.

Does a better SD card improve video quality?

Using an SD card by itself does not directly improve the video quality of a recording. Video quality is primarily determined by the camera sensor, lens, codec, resolution settings, bit rate, and lighting conditions. However, the type and speed of an SD card can have an indirect impact on video recording, such as allowing for faster speeds and larger uploads.

What is the fastest SD card type?

Currently, the fastest SD card type is UHS-II, with read speeds of up to 300MB/s and write speeds of 260MB/s.
