Western Digital has announced a breakthrough innovation for delivering ultra-high capacity hard disk drives to meet the future demands of Big Data with proven data center-level reliability: new microwave-assisted magnetic recording (MAMR) technology should enable hard drives with 40TB of capacity by 2025, helping HDDs hold onto their staying power in the enterprise segment.

At the heart of the company’s innovation breakthrough is the “spin torque oscillator” used to generate a microwave field that increases the ability to record data at ultra-high density without sacrificing reliability. Western Digital’s innovative MAMR technology is expected to offer over 4 terabits-per-square-inch over time. With sustained improvements in recording density, MAMR promises to enable hard drives with 40TB of capacity and beyond by 2025, and continued expansion beyond that timeframe.

For use in Raid 1 or Raid 10 only. I can see these either hosting all the archive stuff which Google and Facebook rarely ever seen or working in a backup appliance, with flash for buffering.

90 drives in 4U, and this isn't even a pure storage shelf, it's a server!

90x 40TB each x 10 (4U each in a 42U rack) = 36,000 TB = 36 PB in 1 rack.... with 2U open for your switches.

40 TB?
It would take me years of maxing out my 1TB cap to fill a 40TB drive.
 
hmmm, that begs the question.. is there really enough porn.. WORTH WATCHING.. that it can fill that thing??
 
I would love to replace all 28 drives in my Ceph cluster at home with just three of those 40TB drives.
 
If you are a content creator, shooting in 8k, you probably can't wait to get a hold of these.

Also I would hate to see the rebuild times if a drive went down in a RAID array. I don't think I could trust drives this size (with the current R/W speeds) unless I was running at least a RAID 50.

If you have data that you haven't even accessed in 2 years, and it isn't something like financial data that you need to keep for several years or family pictures/video, you should probably just delete it. I have a 2TB drive that is just over half full and if I followed my own advise, I could easily cut it in half.
 
Hey, larger capacity hard drives are a cool thing. However, at least for me, not really useful in my personal machines. (Too slow for what I do.)
 
I won’t be holding my breath waiting for this, just like all those other “advances” the HDD industry has been going on about for years.
 
When we get to Kiloquads as in Star Trek: The Next Generation and true holographic storage on isolinear optical chips, somebody wake me up. And for those not in the know, a Kiloquad is roughly 2^100 bytes or something close to it. :D
