4GB Flash Memory

Adding storage to a tablet, camera or cell phone is simple with an SD card. These tiny memory cards have plenty of space to hold personal files, music or photos and come in standard formats designed to fit most personal electronics and computer card readers. Staples offers many 4GB SD cards from manufacturers such as Verbatim, SanDisk and Kingston.

Flexible Physical Formats
The SD standard defines three physical card types: mini, micro and standard. Standard cards are the largest and often used in consumer media devices such as video recorders or digital SLR cameras, while most cell phones and tablets have slots for the smallest card format, micro SD. Mini cards represent the middle ground in size and are relatively uncommon today, replaced by standard or micro-sized cards. All three card sizes are tiny and light. They're about 0.59 to 1.25 inches long and weigh less than 0.1 ounces.

Many modern computers include memory card readers compatible with micro and standard SD cards, making it easy to transfer data between machines. Tiny micro SD cards are so small that they often come with USB or card adapters that make them easier to handle.

High-Speed Data Access
SD cards have speed ratings that indicate how fast they read and write data. With these ratings, it's simple to find a card that matches your intended use. Normal speed cards, Class 2 to 6 are a good choice for basic file storage, single-shot photography or standard-resolution video recording. They read and write 2 to 6 megabytes per second, depending on their speed rating. Fast cards with a Class 10 or UHS 1 rating read and write up to 10 megabytes per second and handle full HD video, continuous still image shooting or speed up large file transfers. The fastest cards, UHS 3, read and write up to 30 megabytes per second. Use these products for capturing 4K resolution video.

Storage for Any Need
While 4GB cards are at the low end of the capacity scale, they're also quite inexpensive, making them an excellent choice for quick file transfers, mailing data to clients or organizing smaller data sets. A 4GB SD card holds about 65 hours of MP3 music or 125 digital photos.

Durable and Reliable 4GB SD Cards
One of the key advantages offered by SD cards is their exceptionally rugged construction. They have no moving parts and withstand environmental conditions that would destroy other storage devices. Most cards are waterproof and shockproof, making them an excellent storage choice for backcountry expeditions, road trips or a jaunt to a local park. They also operate reliably at temperature extremes so you can use them in harsh industrial environments without worrying about data loss. SD cards are unaffected by X-rays and magnetic fields, which eliminates concerns about data integrity when passing through airport security.

SD memory cards combine portability and standardized form factors with rugged construction. They make it easy to transfer files, move photos from a camera to a computer or expand the capacity of a cell phone or tablet. Shop the many storage products available at Staples and find a 4GB SD card that's compatible with your computer or media device.
