Samsung confirms Spinpoint drives

Samsung has finally confirmed the rumours that it is putting their laptop HDDs Spinpoint M6 and M2 into mass production.
TheM2 – which Samsung call 'one of the world's fastest laptop hard drives'– is a 250GB 2.5in hard drive which operates at a 7200rpm rotationspeed, the MP2 which would appear to be well-suited to desktopreplacement laptops and gaming laptops.
The Spinpoint M6, a500GB drive, is built for the expanding data storage needs of modernlaptops and features a 5400rpm spindle speed, a 8MB cache, and 3.0GbpsSATA interface.

"TheSpinpoint M6 is ideal for notebook power users who require vast amountsof storage space for their data, video and music files," said HubbertSmith, Director of Storage, Samsung Semiconductor.
"The MP2 hasspeed, features and capacity similar to a 3.5in hard drive and isperfect for users who require a smaller form factor with advanced datastorage needs."

Meanwhile,Samsung has confirmed that its new Spinpoint F1 RAID Class SATA 1TBcapacity HD has gone into mass production and will be available soon.
Featuringa 334GB per-platter capacity, a 7200RPM spindle speed and a 32MB cache– Samsung has also included its rotational vibration controller and anoptimised system-on-chip (SOC) that lowers power consumption.

This seems really nice but I'd like to know more about power consumption and heat production. Cheap laptop HDDs can run up to 45C, which is pretty hot. I'm guessing they're about the same RPM. I don't think that SOC thing is going to help much. I'm guessing these HDDs are only good in external enclosures but I would never put one in a laptop until I hear its efficiency. Laptops have enough heat and power problems.
