Hitachi TravelStar C4K60: 1.8", 30 GB

6:26 AM - 04/28/2006 by Patrick Schmid

The TravelStar C4K60 carries the same name as Hitachi's 2.5" notebook drives, but is an entirely different product. The rotation speed is only 4,200 RPM, and while the 2 MB L2 cache can be considered a standard size, 8 MB would be attractive from a performance point of view.

Hitachi uses the UltraATA/100 interface and ships CE versions with ZIF connectors, or PC versions that use the Mini-ATA connector. The connector's placement along the length of the drive is intentional, because the length of a 1.8" drive equals the width of 2.5" models: 70 mm or 2.76". This means that any 2.5" drive can be replaced by the C4K60.

The benchmark results of the Hitachi drive are very close to the numbers that Toshiba's 60 GB pre-PMR drive produced: a 20.5 ms average access time and a maximum throughput of 20 MB/s are anything but fast. But then, the C4K60 has several benefits, such as requiring less spin-up power than the Toshiba drives, which helps to increase battery runtime in scenarios where there are frequent drive start/stop cycles. And Hitachi has the upper hand when analyzing drive weight: Toshiba's drives weigh five grams more (0.18 ounces), which corresponds to a 9% or 11% difference for the dual and single platter configurations, respectively.
