Card

Every storage device, be it a hard disk, flash drive or Secure Digital (SD) card is marked with an identification number. In the case of an SD card, the host controller (the socket in your reader or computer) examines the device in order to construct its settings for that particular device. The speed of the card you purchase is truly one of the most crucial aspects of buying an SD card, and is one that’s often overlooked by those unfamiliar with SD speed class ratings. It may seem complicated at first, but in reality, it’s fairly simple to understand.

• Long buffering – when you press the shutter and the camera takes the shot but then it freezes until the data is fully written to the card. • Corrupted video – video cameras might produce corrupted video files if the card speed is too slow or the camera may downgrade the video to match the speed of the card. This could turn full 1080p HD video into a video with much lower resolution. • Shortened clips – when a camera has a higher writing speed than the Flash card, the camera will pause and the video clip will abruptly end once the speed limit of the card is reached. • Burst shooting – many cameras have a burst mode feature where one press produces a repeated series of photographs; this allows users to capture fast-moving events or subjects like pets and children. If the card writing speed is too slow, burst mode setting will not work.

This article was sparked by a recent conversation I had with some folks at SanDisk. We were talking about the numerous types and ratings of SD cards and how there are lots of questions from users about the acronyms, labels and speed ratings associated with SD cards. In this article, we’re going to look at the different types of SD cards, along their speed class designation, and why these are important for you and your camera. By the end of this article, you should have a better understanding of what works in your camera and why. Moreover, you should be able to choose the right SD card for your camera and the way you want to use it.

What Are SD Cards? In 2000, SanDisk, Panasonic and Toshiba formed the SD Association to develop a memory card storage device that could be used across a broad range of consumer electronics. SD cards are the result of standardized specifications established by the SD Association. There are currently 3 different form factors for SD cards. Standard Size SD Card The most common SD card used in digital cameras today measure 24mm x 32mm and is 2.1mm thick.

These cards are the most widely used for digital cameras of all sizes – ranging from compact point and shoot cameras to full-size professional DSLRs. MiniSD Card The miniSD card is 20mm x 21.5mm and is 1.4mm thick. MiniSD cards were previously very common in cell phones; however, over the past couple of years or so we’ve seen microSD cards more widely used in cell phones, cameras and other compact electronics. MicroSD Card The microSD card is 11mm x 15mm – about the size of small child’s fingernail. MicroSD cards are common nowadays in cell phones and are being seen more and more in point and shoot digital cameras.

SD, SDHC and SDXC Specifications (Card ‘Types’) The SD Association develops specifications for all SD cards and devices. In order to use a particular type of SD card in a camera, for instance, the camera manufacturer must adhere to the SD Association’s specifications. Currently, there are 3 main SD card types – SD, SDHC and SDXC.

The key difference in all of these cards is their storage capacity. • Standard SD cards can be made with a max capacity of up to 2GB.

• SDHC cards come in capacities ranging from “greater than 2GB” to 32GB. • SDXC cards range from “greater than 32GB” to 2TB. At present, the 2TB limit is a max theoretical limit only, with most SDXC cards in the 64GB flavor. SD Card Speed Classes SD cards are classified with numerical speed classes. At present, there are 4 non-UHS Speed Classes and 1 UHS Speed Class in use. These ratings are based on a minimum sustained data writing speed. • Class 2: 2MB/s minimum write speed • Class 4: 4MB/s minimum write speed • Class 6: 6MB/s minimum write speed • Class 10: 10MB/s minimum write speed • UHS Speed Class 1 (UHS-I): 10MB/s minimum write speed Note that the card type (SD, SDHC or SDXC) is different from the card speed class (Class 2, 4, 6, etc.).
