The History Of Memory Cards For Cameras
What about the history of memory cards for cameras. First, lets start with the basics. Some may recall that the SD (secure digital) card was introduced in 1999 to compete with the Sony Memory Stick. Of course over the years improvements have come regularly.
One of these improvements is the SDHC (Secure Digital High Capacity), an expanded version of the standard storage device known as SD, and can handle capacity up to 32GB. This format carries the same format as the older SD card types. SDHC uses sector addressing and not byte addressing as is the standard for older types of storage units of this class.
Byte addressing gives support up to a maximum storage of 4 gigabytes. Sector addressing can store information up to a 2TB capacity.
In 2009, SDXC was introduced at the Consumer Electronics Show (CES). The older SDHC can be expanded to over 32 GB but has been limited by the industry standards (SD 2.0 specifications). The first SDXCs are restricted by a 3.0 designation. The newer SDXCs are now restricted by the SD specification 4.0.
