This week, Western Digital Corporation introduced solid-state drives of the iNAND 7250A series, which will be used in automotive technology. The speed of writing sequential data of 100 MB / s and a read speed of 300 MB / s, but these drives can operate at temperatures from minus forty to plus eighty-five degrees Celsius, and in some versions - up to 105 degrees Celsius.
Colleagues from the EE Times website reacted to this announcement in a very peculiar way - they applied for comments to industry experts and a representative of Western Digital Corporation to understand what volumes of storage will be needed for cars of the near future to store important information. According to Intel soon cars will generate up to 4 TB of information per day.
First, as experts explain, "generating" does not mean "storing". Part of the information will be sent to the "cloud", in the internal memory the car will store and process only the most important. Moreover, the needs in the amount of stored information will be much more modest than described by Intel. Secondly, in the next five years, cars will store up to five hundred gigabytes of information on average.
All this information will be distributed among different systems and types of drives. For example, hard drives in the infotainment system will last at least until the end of the decade. Solid-state drives can not yet compete with them either in price or in volume. Toshiba, for example, offers hard drives for car entertainment systems with a capacity of up to 320 GB.
In addition to entertainment systems, capacious storage will require an autopilot system - not only for storing processed images and information received from sensors, but also for detailed digital maps of the terrain. Only cards can hold up to 256 GB of memory. A decent amount will be the software "autopilot", which should be constantly updated to improve the algorithms. The amount of on-board memory will indirectly affect the cost of a specific vehicle configuration. Related Products :
