Finding the Right WiFi SD Card
SD cards have become a very popular storage medium for many different types of devices. Cameras, smartphones, computers, and even specialized equipment like sleep apnea machines can make use of this versatile storage option. eBay has a big selection of SD Cards that are Wi-Fi-enabled.How do WiFi SD cards work?
An SD Card is a form of removable storage that is designed to be a portable solution for your data. A card that is Wi-Fi-enabled allows you to wirelessly connect to the storage drive without removing it from a device. This is made possible by the advancements in storage media. Capacity has been steadily increasing, and the size of the chip required to hold data has steadily decreased. This has left enough room in the housing for the addition of a Wi-Fi chip. Using standard protocols, the card can now communicate with many devices without the necessity of removing it first.How much storage is on a SD card?
SD Cards come in a variety of sizes. The smallest ones can be as little as 4GB. The storage size doubles for each step up: 8GB, 16GB, 32GB, 64GB, 128GB, 256GB, 512GB, 1TB, and 2TB. This makes the SD card an incredibly versatile solution. You can obtain the perfect amount of storage to meet your requirements.Do SD cards have "write-protect"?
Yes, most SD Cards have a "write-Protect" feature. This allows you to lock the card preventing any new information from being stored on it. This can be a handy feature when you have important data on a specific card that you don't want to be erased or overwritten. The card has a small tab along the side that can be slid into a locked position. This creates a small notch in the side of the card. When a device recognizes the notch in place, it will not write to that location.How do you find the right, inexpensive WiFi SD card?
There are a few specifications to consider when choosing the right card for your application. Here are a few to think through:
- Read and Write Speed: Each card may have a different read and write speed. This will dictate how fast they can consume data and how fast they can reproduce it.
- Generation: There are three generations of SD cards. They are SD, SDHC, and SDXC. Make sure that the card you acquire is compatible with your device.
- Connectivity Speed: In addition to the Read and Write speeds, there is a speed rating for the wireless transfer as well. The letter rating "n" is a newer, faster protocol whereas "b" and "g" bands are slower.
