I still remember a month ago, Baidu network disk helpless response? Some netizens spit on Weibo. Only after purchasing a super member, the download speed will maintain a normal level. I hope Baidu.com can give a reasonable explanation.
In response, Baidu's official website responded that “we are really pressureful. As a free cloud storage product, the annual server cost and bandwidth cost are hard. ”
Baidu's network disk said that Baidu's network disk survived to provide free space memory for the majority of users. It is a high cost that needs to be continuously paid annually (the same kind of products at home and abroad have already charged the space size such as iCloud), in addition to this. There are also service costs and bandwidth costs.
So how high is the survival cost of the network disk in China? B station UP main “Paper clip PaperClip”Specially made an interesting video to answer this doubt.
The UP masterTake Baidu Yangquan Data Center as an example. It mentions that the data center can store about 6.14 million terabytes of data. Assuming that 8TBx18 storage servers are used, the hardware cost is 1.96 billion, with an average of 319.5 yuan per TB.
According to the need of one 2400W power supply for every 6 servers, the data center consumes 64,000 kWh per hour. According to the commercial power standard of 0.45 yuan/kWh in Yangquan City, the annual photoelectric cost is burned by 250 million. In addition, the annual optical network fee for data centers of this size is about 400 million yuan. in summary,Even if you don't consider the hardware, the Yangquan data center costs $106 per year for every TB of data stored on electricity and bandwidth.
The hardware needs to be updated, and the electricity and broadband charges are more expensive. It can be seen that it is really not easy to do the network disk. Even 360 companies have abandoned the personal cloud storage service.
