As 2014 gets underway, there is more digital data than ever, stored on everything from portable USB sticks to massive data center disk arrays. In this article, we'll take a high-level look at the main trends in the storage sector, which is the building block of the digital world and an area that's currently undergoing significant transformation.
The data explosion
In December 2012, IDC and EMC estimated the size of the digital universe (that is, all the digital data created, replicated and consumed in that year) to be 2,837 exabytes (EB) and forecast this to grow to 40,000EB by 2020 — a doubling time of roughly two years. One exabyte equals a thousand petabytes (PB), or a million terabytes (TB), or a billion gigabytes (GB). So by 2020, according to IDC and EMC, the digital universe will amount to over 5,200GB per person on the planet.
This sort of data growth clearly requires heroic amounts of storage to keep it available for as long as it's required, and to archive much of it thereafter. Accordingly, IDC estimates that annual worldwide shipments of 'capacity optimized' storage systems will rise from around 22,000PB in 2013 to just under 90,000PB in 2016...(文章)

to get underway "underway" 進行中。指 2014 年一開始到來，電子資料量比以往任何時候都還要多。
disk array 硬碟陣列。其基本思想就是把多個相對便宜的硬碟組合起來，成為一個硬碟陣列組，使效能達到甚至超過一個價格昂貴、容量巨大的硬碟。

數位容量單位：
1 Byte = 8 Bit1 KB = 1024 Byte
1 MB (Megabyte) = 1024 KB
1 GB (Gigabyte) = 1024 MB
1 TB (Terabyte) = 1024 GB
1 PB (Petabyte) = 1024 TB
1 EB (Exabyte) = 1024 PB
1 PB (Petabyte) = 1024 TB
1 EB (Exabyte) = 1024 PB
