  Enter the Sift Lounge to chat with online sifters about anything and everything, or read interesting posts in the Sift Talk forum.
  The Top New Videos list is always full of interesting, current videos. It is always recommended that you have a look through the Top New Videos, but also have a look at these:
  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?
  Post and share it here - VideoSift is the best video aggregator on the Web, where we share, discuss, promote, and interact with the best videos out there on the web. Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

The modern hard drive is an object that can likely hold more information than your local library. But how does it store so much information in such a small space? Kanawat Senanan details the generations of engineers, material scientists, and quantum physicists who influenced the creation of this incredibly powerful and precise tool.

Lesson by Kanawat Senanan, animation by TED-Ed.

Really great. Weird to think that something this high tech may be on the verge of being replaced by solid state storage. I know that spinning disks will still have a place in bulk storage for quite a while but terabyte SSDs are getting cheap!

Thank you, science.

Yes for mass storage, nothing beats the capacity of a good old magnetic hard drive. But for anything else, HDD's are hard pressed to approach an SDD in anything but capacity.
