When Hitachi -- the first disk manufacturer to go perpendicular and subsequently break the 1TB consumer disk drive barrier -- speaks about advances in hard disk technology, you'd be wise to listen. Today they're touting the world's smallest read-head technology for HDDs. The bold claim? 4TB desktop (3.5-inch) and 1TB laptop (2.5-inch) drives within the next 4 years. The new recording heads are more than 2x smaller than existing gear or about 2,000 times smaller than a human hair. Hmmm, Samsung may have to update their SSD vs. HDD graph after this, eh?

Has 3:15 ever looked so foxy? The German-made Harddisc-Uhr (er, shouldn't that be "Harddisk?") adapts just enough disk drive innards and Compaq power supply to coat our mouths in geek-spittle. The platter spins the hour while the minutes creep ever so slowly along the horizontal actuator arm. Practical? No, but we'd go to the mat for first dibs.

Sure, your hard drive does an okay job, spinning around, hefting 200 gigabits per square inch, but wouldn't you know it, the sensors used to read all that data are reaching their physical limits. Enter the National Physical Laboratory in Teddington, UK, where researchers are proposing a whole new sensor design that could result in much thinner and smaller read heads, leading to drives with data densities as high as one terabit per square inch. According to the researchers, the sensors would use less power than current read heads, and could improve the speed of the reader. In the words of lead researcher Marian Vopsaroiu, "You could read back data ten times faster... instead of one GHz, you can read at five to ten GHz." Currently, hard drives use the magneto-resistance effect to read data, needing a constant current which converts resistance to voltage. The new sensors work by using the magneto-electric effect, wherein data's magnetic field will directly generate voltage instead of resistance. The new heads will be smaller and lighter as well, using half as many layers of materials as current sensors, but there are difficulties in putting together the complex alloys of the tiny readers. Want to know all the truly techy details? Grab a cup of strong coffee and hit the read link.

Samsung seems hell-bent on cramming every bit of data it can onto a 1.8-inch drive platter -- just two months after announcing the former capacity champ 120GB SpinPoint N2, the company is pre-announcing a 160GB version. Other than the size, the essential stats remain the same: 4200RPM, 15ms seek time, sub-1W power consumption.
No work on pricing or availability, but our 80GB iPod is beginning to look positively cramped.

The concept of light powered computing has surfaced again, this time thanks to a group of researchers at Radboud University Nijmegen in the Netherlands. Using laser technology that we're not even going to pretend to understand, they've figured out a way of transferring data in speeds measured in quadrillionths of a second -- a measurement so fast even our spell checker doesn't recognize it. The technology is around 100 times faster than traditional magnetic storage methods, but it still has some way to go until it can replace your hard drive: for one thing, the researchers need to figure out a way to reduce the footprint of the laser, currently at an apparently massive 5 microns width. As always, we shall wait in anticipation for any developments.

So in addition to dropping a couple of high-capacity disks this morning, Samsung also gave us some interesting (albeit, depressing) insight into their thoughts on Solid State Disk penetration at a session on SSD vs. hard drives at a product conference in Japan. Big stuff when you consider Samsung's pioneering role to supplant traditional 1.8-inch hard disk drives with flash-lovin' SSDs. We've already heard from Sandisk that SSD prices should fall by about 60% annually. Nice, but SSDs are currently 5x the cost of their mechanical brethren: $7.5/GB compared to $1.4/GB for HDDs. Even by 2010, Samsung (backed by DataQuest research) still estimates at least a 3.x gap: $1.9/GB for SSDs vs $0.9/GB for HDDs according to Hwang's law. In other words, we'll be paying a significant premium for flash memory's lickity quick boots and greater reliability long into the future. Still, a 128GB SSD for $243? Give us two, please.

Oh Samsung, you and your obsession with the "world's biggest" puts even Jersey girls to shame. Chalk-up two more this morning with the world's highest capacity 1.8- and 2.5-inch hard disk drives. We already knew they were working a 250GB version of their 2.5-inch, SATA 1.5Gbps (and PATA) SpinPoint M5 spinning at 5,400rpm. It'll bring an 8MB cache, 24dB whine when idle, 2W power consumption, and 12-ms average seek time when it hits later in the month. According to Samsung, that makes this the largest 2.5-inch disk in a 9.5-mm profile -- whatever. The newly announced 1.8-inch SpinPoint N2 however, brings a world's first 120GB capacity to portable handheld devices like UMPCs (pictured) and perhaps -- if Sammy is real lucky -- future iPods. As such, the N2 spins at 3,600rpm or 4,200rpm with a 15-ms average seek and sub-1W power consumption to help keep your portable device, portable. Production of the 1.8-incher begins in July although we're pretty sure they're already providing samples to OEMs. Hear that Apple? Your 80GB iPod is starting to smell a bit stale. At least toss in a 100GB Toshiba disk for all those movies you're trying to sell us.

Samsung is offering-up a heap of marketing spin along side their new 3.5-inch SpinPoint S166 series of hard disk drives. This time however, there's real truth to their ballyhoo. The new series of SATA 3.0Gbps drives feature a 7,200rpm spin, 8MB buffer, and manage to damp the noise level down to a mere 24/27.5 decibels at idle/seek. That's damn quiet for traditional desktop storage spinning at that speed. Watch for the drives to ship worldwide in 80GB and 160GB capacities sometime this month.
