Remember magnetic tape?
還記得磁帶嗎？
Maybe your first computer had a tape backup system.
也許你的第一臺(tái)電腦還有支持磁帶的系統(tǒng)呢。
And of course cassettes were how you played music in your car before CDs.
當(dāng)然CD出現(xiàn)之前你車?yán)锟啥际谴艓Рシ懦龅囊魳贰?/div>
But Sony's latest foray into tape storage is anything but nostalgic.
但是索尼公司最近突然發(fā)布的磁帶存儲(chǔ)產(chǎn)品可不是用于懷舊。
The company has a new process that lets them store more than 185 terabytes of data on a single tape cartridge.
索尼的這項(xiàng)新的存儲(chǔ)技術(shù)可以使磁帶在單面寫入185TB的數(shù)據(jù)信息。
You'd need about 3,700 Blu-ray discs to hold that much data.
這樣龐大的數(shù)據(jù)量恐怕需要用到3700張藍(lán)光光盤才能裝得下。
And it's 74 times more information than what current data-center tapes can store, on average.
這是當(dāng)前平均情況下數(shù)據(jù)存儲(chǔ)為主的磁帶所能承載信息量的74倍。
With all the data created and collected by mobile devices and sensors, storage is in high demand.
帶有數(shù)據(jù)讀寫和記憶功能的移動(dòng)設(shè)備和傳感器對(duì)存儲(chǔ)功能有很高的要求。
Hard disks cost about 15 times as much as tape.
硬盤造價(jià)大概是磁帶的15倍。
And data centers that store our social media musings on disk use more than 200 times more power than they would if they used tape.
而能存儲(chǔ)硬盤上我們社交媒體上音樂的數(shù)據(jù)中心如果使用磁帶記錄，則需要消耗200倍的能量。
Future data centers will likely use a mix of these new super-charged tapes and hard disks.
未來的數(shù)據(jù)中心也許會(huì)混合使用這些新型超帶電介質(zhì)磁盤以及硬盤記錄數(shù)據(jù)。
Tape is great.
磁帶是很偉大的發(fā)明。
But if it had met all our needs we wouldn't have moved to faster and more durable disks and mp3s as soon as those technologies could be invented.
但如果它在很早以前就能滿足我們的所有需要，那我們就不用讓技術(shù)飛速發(fā)展發(fā)明出超過原有的更耐用的光盤和MP3。
