Main Considerations When Purchasing Bulk SD Cards

When buying a card for your Nikon DSLR camera or a digital camcorder, you’ll need a faster card compared with merely using an SD card in an MP3 player or digital picture frame, for example. Manufacturers and various tech companies using cards are strict on their requirements in utilizing proper write speeds and supported sizes. Performance is key.

The following guide includes much more information about SD cards to help steer your purchasing decision.

What Is an SD Card?

An SD card, short for secure digital card, is a compact, lightweight and removable flash memory card offering high-capacity storage. While it is one of several types of memory card available, the SD card is among the most popular.

Measuring 1.25 by 0.95 inches and weighing 2 grams, SD cards are used in computers and many electronic devices such as digital video camcorders, digital cameras, digital picture frames, cell phones, game consoles, and MP3 players.

In recent years, a smaller form of SD cards called micro SD cards has emerged to help meet the needs of smaller devices such as cell phones.

A Brief History of SD Cards

SD cards hit the market in 1999 and helped transform storage for electronic devices. As their storage capacities ballooned, these devices became ever more powerful.

SD cards have become capable of storing as many as tens of thousands of images and songs along with hours of HD video on a single card. Users can store numerous program files in a variety of file formats for convenience and security.

What’s the Difference Between SD and Micro SD Memory Cards?

SD cards are available in three sizes: standard, mini, and micro. The standard SD card is the largest.

Micro SD cards have become popular because they are small and fit easily into portable devices such as cell phones. While the connection, port required, and physical size of the cards are different, they both work in devices that accept full-size SD cards.

The micro SD cards offer a lower storage capacity than regular SD cards, but they are available in a wider range of storage capacities than miniSD cards.

SD cards are generally used in devices that have a larger form factor, while micro SD cards are used in smaller devices. Both SD and microSD cards have the same dimensions, but micro SD cards are about one-third the size of an SD card.

Many newer devices, like cell phones and digital cameras, use micro SD cards instead of regular SD cards because they’re smaller. Because of this, mobile phone manufacturers are more likely to place a bulk micro SD card order rather than purchasing smaller amounts or opting for SD cards.

Size Difference between SD Card and Micro SD Card

SD cards are about twice the size of a postage stamp. They’re available in capacities up to 1TB. Micro SD cards are about the size of a fingernail, and are also available in capacities up to 1TB.

Uses for SD Cards

SD cards have a wide variety of uses, due to their small size, large storage capacity, and high speed. Some common uses include:

– Storing digital photos, especially in professional cameras
– Storing digital videos
– Playing music
– Running operating systems in portable devices such as netbooks
– Backing up files on computers
– Storing data for GPS devices
– Storing map information on portable devices
– Storing contact information on cell phones
– Playing video games
– Loading software onto portable devices
– Image and video storage for dash cameras
– Collecting and storing footage on a card for a video doorbell or similar surveillance system
– Downloading files from the Internet

Who Uses Bulk SD Cards

Individuals and organizations in a range of industries can benefit from the purchase and use of memory cards in bulk. A professional photographer or videographer might use SD cards in digital video cameras or provide their clients with their own SD cards full of photographs and video footage.

Other professionals who work with AV equipment, mobile phones, computers, and more can also benefit from bulk SD card purchases. Drivers, especially those who cover great distances or need to keep accurate records of their journeys, can also use SD cards in a dash cam to help them track and monitor their travels.

Common Card Sizes

In scoping out SD cards, zoom in on card capacity. Small and large card sizes are available on Everything But Stromboli, carrying capacities up to 1TB. These common SD card sizes meet most people’s needs, although it’s worth noting that the most common sizes are 16GB and 32GB.

If you intend to record lots of HD video and take thousands of RAW or high-megapixel images at a wedding or other event or while on vacation, for example, you’ll benefit from investing in high-capacity cards such as 64 GB, 128 GB, or even 256 GB.

With bulk purchases, although 8GB is a common size, this storage capacity is giving way to higher capacity cards. Cards offering 16 GB and 32 GB of storage capacity are overtaking 4 GB to 8 GB cards in popularity.

Years ago, the larger a card’s internal storage size meant a slower write speed, but this is no longer the case. As write speeds increased from 48 MB to 80 MB per second, larger-capacity cards have soared in popularity.

Class 10 cards write at minimum 10MB/s sustained, making the 64 GB, 128 GB, and 256 GB SD cards more appealing to move files, especially 4K video files, which are very large files. In time, we’ll see terabytes become available on these cards, and we have already seen a video speed class emerge.

SD Card Specs: What Does Each SD Card Terminology Indicate?

The Everything But Stromboli team has produced this handy guide breaking down SD card specs. These cards have a lot of terminologies, making it confusing for consumers to understand what kind of card(s) they need.

– SDHC: Secure Digital High Capacity, which generally covers card sizes between 4 GB and 32 GB.
– SDXC: Secure Digital eXtended Capacity, optimized for full-HD (1920×1080 resolution) recording and is compatible with only SDXC devices, commonly media devices.
– Class or series: The class is the rated classification for a card’s write speed. Class indicates how fast information is uploaded and written onto the device. Cards have been made as Class 2, Class 4, Class 6, and Class 10, with the latter writing at a speed of at least 10 MB per second.
– UHS: Ultra High Speed is another designation of write speed, a drive with a U1 symbol writes at 10 MB per second and a U3 writes at 30 MB per second.
– V: A “V” designation represents a video-oriented card with the video class speed of V6 (6 MB per second), V10 (10 MB per second), V30 (30 MB per second), V60 (

60 MB per second), and V90 (90 MB per second). Video requires a certain write speed to record a given quality of video. The higher the quality, the higher the necessary write speed.

SanDisk, for example, labels its card classes with the names Ultra, Extreme, and Extreme Pro, with each tier operating at higher read speeds than the previous and much faster write speeds. The Ultra is a step up from a standard SD card, and the Extreme variety is better still. The Extreme Pro card performs the fastest read, write, and transfer speeds and may be the card for you if you intend to record lots of 4K video.

Bulk SD Cards

When you purchase bulk SD cards, the larger the order, the cheaper the price. Buying bulk SD cards enables prices per card to be the most affordable compared to purchasing them individually.

Lots of companies buy bulk SD cards for use by their employees in business equipment as well as in packaging with electronic devices.

Digital photographers and videographers may also purchase wholesale SD cards to send files to clients.

If you need effective data storage for different projects or products, buying in bulk will help you get SD cards at the most affordable prices.

How Long Do SD Cards Last?

This is a difficult question to answer because it depends on how often the card is used and what type of files are stored on it. The average lifespan of an SD card can be anywhere from two to 10 years.

To get the most out of your SD cards, it’s important to keep them clean and store them in a safe place when they’re not in use.

How Do SD Cards Work

SD cards are a type of flash memory storage device. They are used in a variety of consumer electronics devices, including digital cameras, smartphones, camcorders, tablets, and laptops. Devices that use SD cards have a slot on the side or back of the unit into which the card is inserted.

The SD card has three parts: the controller, the memory, and the bus. The controller is what tells the device how to use the card. The memory is where the data is stored, and the bus is what transfers the data between the controller and memory.
