An Overview On Memory Cards
A memory card is a convenient way to store your electronic data. Whether it’s photos, videos, games, documents or more, you can save them to a memory card to ensure they are safe and easy to access when you need them. Memory cards are used in a number of devices, such as cameras, phones, game consoles, printers and even TVs, in addition to computers and laptops. Keep in mind that different types of devices use different memory cards. It’s important to know what you need the memory card for so you can get the right one for your needs.
The basic format of memory card is the SD card, which has a storage capacity of four GB. An SDHC memory card is a level up from the SD card and has a much higher capacity of up to 32 GB. It is best for storing high-resolution photos and videos. Another type is the SDXC memory card, which has a higher capacity than that SDHC card. It can store up to two TB of data.
The MicroSD memory card is much smaller than a regular SD card. It is used in portable items like mobile phones. There are also micro SDHC and micro SDXC memory cards, which are typically only compatible with specific devices that have their slots. Another option is the compact flash card, which is larger and has more connections than a regular SD card. These are for professional photographers.
In addition to selecting the type of memory card you need, you’ll need to note how much space you require to store data. Consider the types of files you need to store and how big they are. This is especially important if you’re storing high-resolution photos, videos or games, as they take up a lot more room than most documents.
The Memory Card Buying Guide
- Be sure to check whether the memory card you’re interested in is compatible with the device you want to use it with. Check to see which memory card slot is included in your device. Some devices will have multiple slots for memory cards. Note that some devices that support SDXC memory cards will also be backward compatible and also support SDHC and SD cards. However, not many memory card slots are forward compatible. For example, if a device supports an SDHC memory card, it likely cannot support an SDXC memory card.
- When considering capacity, you’ll also want to consider durability and portability. For example, if you store all of your files onto one memory card, and it falls and breaks, you may lose all of your files at once. This is why many professionals prefer to use multiple memory cards with a smaller capacity. Plus, you’ll want to ensure that the card is highly durable and will not break if dropped.
- In addition to surviving a drop, consider how many times a memory card can be inserted and re-inserted without getting damaged. Typically, most can withstand around 10,000 cycles. However, in order to prevent excessive wear to your memory card, you’ll want to make sure that you save data evenly across the card.
- If you take your memory card on the road, such as places near water or near extreme hot and cold temperatures, that will need to be a factor in the durability of the card. You can find water-resistant and water-proof memory cards as well. Some can also withstand x-rays and magnetic fields.
- Speed is a factor if you frequently store large amounts of data on your memory cards. You can save time by going with a memory card that has a high transfer rate.
