硬盘的容量每年以2倍以上的速度成长,似乎比应用在微处理器与3D显示芯片上的摩尔定律(3年4倍)更为惊人。目前硬盘单盘片的容量已经达到了15GB,甚至有最高75GB的硬盘产品。不过,硬盘的优势不仅在于日益壮大的容量,而是在于它令人无法抗拒的价格,目前市场上20GB的产品已经不到1000元。加上98年底所推出的Ultra ATA/66规格,到现在也已经有相当成熟的支持环境。所以,面对这种便宜又好用的计算机存储设备,形容现在是硬盘的“采购时节”也不为过。
Hard disk capacity grows more than two times a year, and seems to be even more astonishing than Moore’s Law (4x 4x) for microprocessors and 3D graphics chips. The current capacity of a single hard disk has reached 15GB, and even the highest 75GB hard drive products. However, the advantage of a hard drive is not only the growing capacity, but its irresistible price, the current 20GB of products on the market has less than 1,000 yuan. Coupled with the Ultra ATA / 66 specification introduced at the end of 1998, there is now a fairly mature support environment. So, in the face of this cheap and easy to use computer storage devices, described as the hard disk is now “purchasing season” is not an exaggeration.
