Seagate just shattered the record for storage density on hard drives by using a novel recording method to stuff 1 terabit into a square inch. That’s nearly twice the old record. Hard drives are about to get huge.
Seagate squeezed all of that data into that tiny space by using “heat-assisted magnetic recording” instead of perpendicular recording to write data to disk. ExtremeTech reports:
HAMR, which was originally demonstrated by Fujitsu in 2006, adds a laser to the hard drive head. The head seeks as normal, but whenever it wants to write data the laser turns on. Reading data is done in the conventional way. Just so you understand how small the magnetic bits are in a HAMR drive, one terabit per square inch equates to two million bits per linear inch; in other words, each site is just 12.7 nanometers long – or about a dozen atoms.
In the short term the technology will result in new 6TB 3.5-inch desktop drives and 2TB 2.5-inch laptop drives. Currently the largest capacity drives are 1TB and 3TB respectively for laptops and desktops. That’s already an impressive boost in capacity.
In theory, though, HAMR should allow hard drives to write up to 10TB per square inch, which means that in the future you could potentially cram about 60TB onto a 3.5-inch drive. [Seagate via ExtremeTech]
Earlier today, AT&T announced record sales and activation numbers for the new iPad. During the Apple dividend/buyback call, Apple CEO Tim Cook spoke of a “record weekend” for the new iPad. Unfortunately, neither had actual numbers to share. And that was odd since normally when Apple has a new record number to crow about, crow they do. This was more of an Amazon maneuver where “records” are set by products selling 4x of another unstated number.
Turns out Tim Cook just didn’t want to spoil the surprise. Apple has just issued a release with their actual sales numbers for the first weekend of the new iPad. And the numbers are big. Very big. Three million iPads sold in the first three days big.
So how does that stack up to the previous versions of the iPad? Well, Apple didn’t officially announce first weekend sales for the iPad 2, likely because they were very constrained. Analyst estimates pegged the number sold somewhere between 500,000 to somewhere just north of 1 million. So even using the bullish numbers, this iPad launch was roughly 3x as large as the launch last year.
Two years ago, Apple sold 300,000 iPads on the first day of sales. Again, the pace here seems to be about 3x that. For comparisons sake, Apple sold 4 million units of the iPhone 4S in its first weekend late last year.
Over the weekend, a few analysts were jumping over one another to be the first to predict timid sales of the new iPad. Those analysts, once again, now look like huge assclowns.
The quote part of the release below:
“The new iPad is a blockbuster with three million sold―the strongest iPad launch yet,” said Philip Schiller, Apple’s senior vice president of Worldwide Marketing. “Customers are loving the incredible new features of iPad, including the stunning Retina display, and we can’t wait to get it into the hands of even more customers around the world this Friday.”
