Hello happy reader,

On July 10th, Seagate “unveiled the industry’s first 1.5-terabyte desktop and half-terabyte notebook hard drives to meet explosive worldwide demand for digital-content storage in home and business environments.” Don’t need no explosive disk drive but, in the case of storage, more is better. The 11th generation Barracuda 7200.11 1.5TB mechanism, “marks the single largest capacity hard drive jump in the more than half-century history of hard drives – a half–terabyte increase from the previous highest capacity of 1TB, thanks to the capacity–boosting power of perpendicular magnetic recording (PMR) technology.”

PMR is a novel magnetic coating composition…Imagine a box of brand new pencils. Pencils are usually hexagonal so, if you were to empty the box onto a table and then gather the entire pile into one hand, the pencils would all line up in parallel, tightly packing together into a relatively small space. PMR takes advantage of this tight packing by using magnetic material that resembles those pencils in micro–miniature. The “pencils” are attached, coated actually, such that they are “standing up,” perpendicular to the platter surface. The flying read/write head, they really do fly, “sees” only the very tightly packed ends of the magnetic material. Thus, the areal density is very high relative to the old school approach whereby the magnetic needles are lying flat, parallel to the platter. This mechanism is the 5th generation to use PMR.

Ye hah, this announcement means I’ll be able to deliver very high capacity storage configurations in really compact spaces once the drives are qualified. As Martha would say, “That’s a good thing.”

In the same press release, Seagate announced two new 2.5″ 500 GB PMR drives, the Momentus 5400.6, and the Momentus 7200.4, 5400 and 7200 rpm respectively. These mechanisms “deliver the best combination of capacity, mobility and durability for mainstream and high-performance notebook computers, external storage solutions, PCs and industrial applications requiring small form factor.” The 2.5″ form factor is what is commonly found in laptop computers so, this means that your future portable will not suffer from a lack of storage capacity.

“Both Momentus drives are built tough enough to withstand up to 1,000 Gs of non-operating shock and 350 Gs of operating shock to protect drive data, making the drives ideal for systems that are subject to rough handling or high levels of vibration. For added robustness in mobile environments, the Momentus 5400.6 and 7200.4 are offered with G-Force Protection, a free-fall sensor technology that helps prevent drive damage and data loss upon impact if a laptop PC is dropped.” The built–in accelerometer detects changes in acceleration and parks the heads in a free fall of as little as 8 inches.

That’s all for today…TTFN.
