DNA, the information-storage technology preferred by biology, can cram up to 215 petabytes of data into a single gram.

DNA是生物学偏爱的一种信息存储技术，它可以将215拍字节的数据塞进一克的物质中。

Billions of files, about one and a half petabytes of data!

高达数百亿个文件，约莫一点五拍字节的数据量！

The data center sees 100 petabytes of photos and videos per day.

数据中心每天查看 100 PB 的照片和视频。

Even then, atomic clocks, smart algorithms and countless hours of supercomputing are needed to construct an image from several petabytes (1 PB equals one million gigabytes) of gathered data.

即便如此，仍需要原子钟、智能算法和无数小时的超级计算才能从数 PB（1 PB 等于 100 万千兆字节）的收集数据中构建图像。
