"It is a one terabyte product using only three discs. Whereas competitor products might require four discs or five discs. What's unique about having fewer discs...Samsung and competitors each spin at 72 hundred RPM. Now if you're using fewer heads and discs, that means the data is more tightly packed together. That means when you spin at the same speed you actually, by virtue of having the bits closer together, you actually read faster or write faster. By having less mass means you require less power, which means you don't consumer as much power. So Samsung is not only best in class in performance, we're best in class in low power consumption." A terabyte is equal to more than a thousand gigabytes. And while everyone may not need that much storage, if you take lots of digital pictures...with a ten megapixel camera....shoot digital video or record.TV shows on a PC.....the added space is welcome. You can find the Spinpoint F1 selling for under 220 dollars. Bloomberg Boot Camp, I'm Fred Fishkin.
