But prices for lithium-ion batteries have fallen fast—by almost half just since 2014. Electric cars are largely responsible, increasing demand and requiring a new scale of manufacturing for the same battery cells used in grid storage. California is mandating that its utilities begin testing batteries by adding more than 1.32 gigawatts by 2020. For context, consider this: In 2016, the global market for storage was less than a gigawatt.

The problem of reliable distributed storage is arguably even more historically challenging than distributed consensus. In the algorithms required to implement distributed storage correctly, mistakes can have serious consequences. Data sets in distributed storage systems are often extremely large, and storage errors may propagate alarmingly while remaining difficult to detect. The burgeoning size of this data is also changing the way we create backups, archives, and other fail-safe measures to protect agains

Previously scientists at IBM and other institutes have successfully demonstrated the ability to store 1 bit per cell in PCM, but today at the IEEE International Memory Workshop in Paris, IBM scientists are presenting, for the first time, successfully storing 3 bits per cell in a 64k-cell array at elevated temperatures and after 1 million endurance cycles.
“Phase change memory is the first instantiation of a universal memory with properties of both DRAM and flash, thus answering one of the grand challenges of our industry,” said Dr. Haris Pozidis, an author of the paper and the manager of non-volatile memory research at IBM Research – Zurich. “Reaching 3 bits per cell is a significant milestone because at this density the cost of PCM will be significantly less than DRAM and closer to flash.”
Therefore Brewer’s group proposes increasing the height of the standard HDD, currently established at an average of one inch for 3.5” disks and 15mm for 2.5” drives, in order to store more platters per HDD – an economical approach from the point of view of packaging, optimal use of printed circuit boards and the drive’s motor actuator.
The SSD Endurance Experiment represents the longest test TR has ever conducted. It’s been a lot of work, but the results have also been gratifying. Over the past 18 months, we’ve watched modern SSDs easily write far more data than most consumers will ever need. Errors didn’t strike the Samsung 840 Series until after 300TB of writes, and it took over 700TB to induce the first failures. The fact that the 840 Pro exceeded 2.4PB is nothing short of amazing, even if that achievement is also kind of academic.

If you write a lot of data, keep an eye out for warning messages, because SSDs don’t always fail gracefully.
When data is abundant, intelligence will win
Putting the power to publish and consume content into the hands of more people in more places enables everyone to start conversations with facts. With facts, negotiations can become less about who yells louder, but about who has the stronger data. They can also be an equalizer that enables better decisions and more civil discourse. Or, as Thomas Jefferson put it at the start of his first term, “Error of opinion may be tolerated where reason is left free to combat it.”

It then goes on to say this:
The vast majority of computing will occur in the cloud
Within the next decade, people will use their computers completely differently than how they do today. All of their files, correspondence, contacts, pictures, and videos will be stored or backed-up in the network cloud and they will access them from wherever they happen to be on whatever device they happen to hold.
Of course google wants this for everyone will need to use services like google to access their data. Do people really need all their data accessible to them 24/7? Can anyone trust the security of one’s data when placed in the hands of a stranger?
A bird in the hand is worth two in the bush. There is nothing more secure than a hard drive or more (one or more for backups) in a safety deposit box. No one needs to access their tax returns from anywhere at any time just because they can.
In a statement, Snapchat puts the blame on third party applications like Snapsaved.com that use its API to allow Snapchatters to save its disappearing messages on their devices, or worse yet, on a remote server. “We can confirm that Snapchat’s servers were never breached and were not the source of these leaks,” a Snapchat spokesperson writes in a statement. “Snapchatters were allegedly victimized by their use of third-party apps to send and receive Snaps, a practice that we expressly prohibit in our Terms of Use precisely because they compromise our users’ security.”

This should have been obvious from the beginning. Nothing can stop an end user from taking a screenshot of an incoming photo. Their “privacy” claim was bogus from the beginning and not sure why anyone took this business model seriously. More …
But even if Snapchat users’ data was accessed via someone else’s servers, that doesn’t make the breach any less of Snapchat’s problem, says security researcher Adam Caudill. He’s been reverse engineering Snapchat’s API to demonstrate exactly the problem of rogue third party apps for years. “Your average developer can build something in a day’s time that interacts with Snapchat’s API and saves everything that comes through it,” Caudill says. “Quite honestly, I’m surprised this hasn’t happened sooner.”
For this report, Backblaze took a look at 15 different HDD models from the three aforementioned major brands. Earning impressive marks for reliability was the Hitachi 3TB Deskstar 7K3000 (HDS723030ALA640) with a 0.9 percent failure rate and an average lifetime of about 2.1 years.

The worst of the bunch, meanwhile was the 1.5 TB Seagate Barracuda Green (ST1500DL003), with an average lifespan of 0.8 years. Ouch!
Facebook is now experimenting with a storage prototype that uses racks of Blu-ray discs instead of hard drives. The discs are held in groups of 12 in locked cartridges and are extracted by a robotic arm whenever they’re needed.
One rack contains 10,000 discs, and is capable of storing a petabyte of data, or one million gigabytes.
