The Morning After: '5D' storage could fit 500TB on a CD-sized disc

Blu-rays are so done. Using high-speed lasers, researchers have created new data storage tech that could write and keep 500TB of data on a CD-sized glass disc. The 5D storage tech has higher writing speeds that might make it feasible to large-scale archiving projects. Each file uses three layers of nanoscale dots. The dots' size, orientation and position within the three standard dimensions make up the five "dimensions."

This kind of optical storage isn’t new, but there were problems in the past, particularly slow writing speeds. The new technique has sped this process up substantially, to around 230 KB per second. And, yes, that sounds pretty slow, but it could provide a way to backup data, essentially forever. It's been estimated the storage medium could withstand temperatures up to 1,000 degrees C and last 13.8 billion years at room temperature without degrading.

I wish anyone other than Kanye had made the Stem Player

Fun, but pushing the limits of the technology.


So what is it? Well, it’s basically a tiny puck-shaped computer dedicated to remixing Kanye’s latest album. Using it, you can change the volume of different stems, or tracks, in the songs on Donda. For instance, if you’re wondering what “Off the Grid” would sound like as an instrumental, you can simply turn down the vocals. Terrence O’Brien begrudgingly tested it out.

Beats Fit Pro review

All the perks of AirPods with a more comfortable design.


Thanks to some early hints in iOS 15.1, Beats’ latest earbuds are hardly a surprise. The company officially debuted its latest model: the $200 Beats Fit Pro. With a similar design to the Studio Buds that arrived earlier this year, this new pair offers active noise cancellation (ANC) alongside almost all of the features from Apple’s third-generation AirPods. Its shape seals off your ear, so ANC and transparency mode are available. Bass levels are ample without overpowering for a sound profile that’s noticeably better than Beats’ previous model. Our headphones expert Billy Steele seems to like them.

iPhones could soon detect car crashes and auto-dial 911

Apple is working on the same feature for its Watch, too.

Apple plans to unveil a feature called crash detection for both iPhones and Watches, according to a Wall Street Journal report. The feature would supposedly use sensors like the accelerometer built into Apple devices. Apple has reportedly been working on this for several years and testing it using real-world data.

Years ago, Google introduced a similar feature for the Pixel 3 and Pixel 4 via its Personal Safety app that can detect when you've been in a car crash and alert emergency services. Even GM has been offering it for years in its cars with OnStar and recently introduced crash detection to smartphones via the OnStar Guardian app.
