垃圾邮件每天吃掉512TB互联网空间
据瑞典的服务器维护与网站监测公司Pingdom的测算，每天在互联网上发送的垃圾邮件数量达到1.2万亿封，根据每封邮件大小为4.27KB计算，每天互联网空间有512TB被垃圾邮件吃掉。
CyberNet进一步说明，1TB价格是每年250美元，那么一天的垃圾邮件如果放在服务器里不删除的话，就等于吃掉了 12.8万美元！那么一年呢？这也是为什么Google要定期删除垃圾邮件的原因了。
Spam mail eats up 512TB every day!
Pingdom, the Sweeden based website maintaining and monitoring company, has estimated that every single day there are 120million spam emails on the internet, the average size of a spam email is 4.27 KB, so everyday the spam emails eat up 512TB space!
CyberNet calculates a little more, “…the cost of a one terabyte drive is about $250. If you had enough of these to cover the 512 terabytes that are eaten every day, it comes out to $128,000 worth of hard drive space each day! ”
