Hard Disk Drives & SD Cards

The need for data storage grows exponentially with every new megapixel sensor and with every new technology (which was high definition [HD] video until only a year or two ago); today the 4k, tomorrow 8k, and beyond. The surveillance industry is one of the largest consumers of data storage media because of the need for the constant recording of information from cameras (with the associated time/date, GPS, various interfaces, and so on). Hard disk manufacturers were ignorant of the CCTV and surveillance industry until it switched to digital storage. They then realized the size of this new data storage market.
