Computer virus
Surprising numbers are faced by Symantec’s annual cyber security report: a lot of users have come across an atrocity last year from computer criminals. 69 percent of the members of the Millennium (Y + Z) generation on social networking sites have fallen victim to cyber crime in the United States, but the situation is not rosy for the entire computer population: more than half of the adult Internet population (about 143 million people) are affected by malicious program, virus, spyware, blackmail virus, or phishing scam last year – says Symantec’s 2017 survey, which, of course, has not only done in the United States, but in 20 other countries around the world. The Norton Cyber Security Insights report also pointed out that we are already talking about 978 million Internet users globally that somehow have access to computer criminals. The most common incidents were: viral infection (53 percent), credit card fraud (38 percent), password forgery (34 percent), unauthorized access to one user’s account (34 percent), scam on online shopping (33 percent), cheating emails or sensitive personal information click fraud (32 percent). As a result, consumers who have been subjected to cybercrime have globally lost $ 172 billion, an average of $ 142 per victim.
40 TB Western Digital
Huge 40TB hard drives are on the horizon, thanks to Western Digital
Western Digital (WD) has announced its next biggest innovation in hard drives, and it could bring capacities all the way up to 40 terabytes.
At its San Jose, California headquarters, WD announced the world’s first microwave-assisted magnetic recording (MAMR) hard drives. The storage company claims its innovative MAMR technology will enable its future hard drives to store more than four terabytes-per-square-inch.
The result will enable hard drives that could come with 40 terabytes of capacity and beyond by 2025.
At the heart of WD’s MAMR technology is a new spin-torque oscillator that generates a miniature microwave field that increases the ability to record ultra-high-density data.

How’s it all work?
Basically, as the recording arm floats over the hard drive’s data platter, this extra radiation from the spin-torque oscillator helps excite the disk drive’s data storing medium to increase the amount of information that can be written.
Previously, WD looked into a heat-assisted magnetic recording (HAMR) technology to dramatically increase data storage capacity. However, the company realized this process introduced an entirely new manufacturing process as well as too much heat that ruined the reliability of hard drives by cooking them at 400- to 700-degrees Celsius.
By comparison, the spin-torque oscillator MAMR achieves the same effect without any additional heat or having to retool hard drives completely.
For now, MAMR technology will be first introduced into WD’s enterprise and server storage solutions. But, given that the company’s helium-filled Helio drives in November 2013 trickled down to the consumer market by March 2016 (in less than three years), we’re likely to see MAMR hard drives for regular consumers soon enough.
