The usability of memory cards is known to all. In this era of smartphones, digicams, handycams, DSLRs etc. that come with the option of expandable memory, memory cards play a crucial role. With varied capacities, they allow us to save any number of pictures, audios and videos in our devices without worrying about deleting the unnecessary files instantly.
However, not many of us are aware of the fact that depending upon the device we are using, we might need to use different types of memory cards. Confused? Soham was too when he learnt from his friend Deepak that he couldn’t use his phone’s memory card in his newly purchased digicam.
Soham and Deepak were sitting in a cafe, where the former had invited the latter to show his digicam that he had bought with his first salary. After the two friends discussed about the specifications of the device, Deepak asked Soham if he had purchased a memory card for the camera.
To this, Soham replied that he had a spare 64 GB memory card from his previous phone, which he would use in the camera. Deepak stared at his friend in utter disbelief. At first, he thought that Soham was joking; but when Soham responded with an equally blank stare, Deepak understood that his friend was unaware that a phone’s memory card wouldn’t be compatible with a camera.
Soham read that SD Cards were the most popular format of digital memory card used in compact cameras, manufactured by companies like Sony, Canon and Epson, among others. These cards were about the size of a postage stamp and featured lock switch to write protect the contents. These were compatible with any device that has an SD card mark on it and devices that supported SDHC and SDXC cards.
Second in the link were MMC cards, which were of the same size as an SD card, but differed in capacities. Soham learnt that these were compatible with any device that supported an SD card. However, a device supporting only MMC cards does not support SD cards. He also found that MMC cards were compatible in some models of Sony and Nikon cameras.
These are much smaller than SD card, but use the same technology to function. These are specially designed to be compatible with portable devices like smartphones and music players. However, the site also said that users must check specifications of the smartphones to ensure their compatibility.
Next in the list were compact flash cards. Soham learnt that these memory cards were bigger than SD cards and are used in DSLR cameras such as Nikon D70 and Canon EOS 1Ds Mark II, among others. They establish contact with the device through a series of pins that accepted pins from the reader. Although these cards didn’t feature a write protect switch, yet the cards’ contents could be protected on most cameras.
XD cards were listed next in the portal. Soham found that these memory cards were smaller in size than SD cards and are based on the technology used by SmartMedia memory cards. Until SD cards came into existence and became compatible with most models of digital cameras, XD cards were used in FujiFilm cameras.
SDHC (Secure Digital High Capacity) card came into the picture when there was an increase in the demand for high-resolution pictures and high-definition videos.
Talking about shape and size, it is quite similar to the standard SD cards. An SD card that is of 4 Gb or above that is considered to be an SDHC card. Before buying an SDHC card, make sure that your device accepts it or not.
The term SDXC refers to Secure Digital eXtended Capacity. This memory card has a higher capacity when compared to the SDHC card. SDXC cards start at 64 GB and can go up to almost 2 TB.
Memory sticks were last in the list. Soham read that these type of memory cards were generally used in Sony cameras and other portable devices like the Sony PSP. Its latest model, Memory Stick Duo, was a slightly smaller version of an SD card. While many modern Sony digicams also supported normal SD cards, the brand continued to manufacture memory sticks and emphasised on using them.
An enlightened Soham returned Deepak’s phone and thanked him. He then realised that his digicam was SD card compatible. Realising that his spare memory card is a micro/mini SD card, he asked Deepak to accompany him to a nearby store to buy an appropriate memory card.
