Scientists in a lab created a technique to encode bits into very tiny spaces across 100 layers.&lt;p&gt;The proof of concept technique they created in a lab is so slow that it would take a full second for 10 pixels on the disc.&lt;p&gt;The headline claiming that this is a new cousin of DVDs is clickbait. It’s a lab technique, but someone extrapolated it into the same area of a DVD and imagined how many bits it could theoretically hold.</text><parent_chain></parent_chain></comment><story><title>DVD&apos;s New Cousin Can Store More Than a Petabit</title><url>https://spectrum.ieee.org/data-storage-petabit-optical-disc</url></story>
<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>ksec</author><text>&amp;gt;All in all, a DVD-size version of the new disc has a capacity of up to 1.6 petabits—that is, 1.6 million gigabits. This is some 4,000 times greater data density than a Blu-ray disc and 24 times that of the currently most advanced hard disks.&lt;p&gt;1.6 petabits is 0.2PB, or 200TB. The highest shipping density hard drive is 22TB or 30TB depending on whether you are consumer or cooperate customer. But even with 22TB is is only 9 times. Not 24 times.</text><parent_chain></parent_chain></comment><story><title>DVD&apos;s New Cousin Can Store More Than a Petabit</title><url>https://spectrum.ieee.org/data-storage-petabit-optical-disc</url></story>
