IBM Doubles Mobile Drive Capacity
New Travelstar will have 80GB capacity and spin at up to 7,200 rpm.IBM has doubled the capacity of its mobile hard drives and is planning faster spin speeds, officials said Wednesday. The new Travelstar 80GN, holding up to 80GB of data, accomplishes its size by using a third layer of magnetic material and a second layer of the chemical ruthenium. The drive will be generally available early next year and initially will spin at 4,200 revolutions per minute. A 5,400-rpm version called the GNX and an as-yet unnamed 7,200-rpm version are also due next year, said Bill Healy, vice president of mobile storage, in San Jose, Calif. IBM will soon rename the entire series, he said.
The new drives are primarily for laptop computers and could also be used for embedded devices, such as digital video recorders, he said.
