The explosion of connected devices and digital services is generating massive amounts of new data. Digital world is growing exponentially from 4.4 zettabytes (1021 or 1 sextillion bytes) of digital data created in 2013 to an expected 44 zettabytes by 2024. Digital information can be stored in different types of device depending on the use and how frequently the data need to be accessed. Hard disk drives are magnetic devices that allow storing terabytes of data for long time, however speed of access to the data is relatively slow (a few milliseconds).
As the volume, velocity, variety, value and longevity of both Big Data and Fast Data grow, a new generation of storage technologies are needed to not only support ever-expanding capacities, but ultimately help our customers analyze and garner insights into our increasingly connected universe of data, said Mike Cordano, president and chief operating officer at Western Digital.
The amount of data you can squeeze onto a hard drive continues to grow by leaps and bounds, with Seagate announcing a 60TB SSD late last year. Earlier in 2017, IBM scientists who have built what they say is the world’s smallest ever magnet, which uses a single atom to store information. Their proof of concept could one day lead to credit card-sized hard drives capable of holding the entire 35 million song iTunes library.
The video monitoring market is growing rapidly worldwide thanks to the almost insatiable demand to have visual sensing of the environments around us — be it in and around our homes, buildings, factories, enterprises or infrastructures. Micron has introduced new industrial microSD cards for video surveillance edge storage will give system designers unprecedented freedom in designing and cost-optimizing large distributed surveillance systems. These microSD cards, with extremely high density and reliable data storage at the silicon level, make it possible for the first time to store many days of video in the camera itself.
