Internal hardrives typically contain a volume vary from 60GB to 2TB. While an external laptop drive is a unattached hardware which can be plugged to the laptop's USB or FireWire port, its capacity ranges are similar. Laptop drives have a speed of 7,200 rpm for processing data at a faster pace, with older hard disks still supporting 5,400rpm.
The common operating power utilization of a 7,200 RPM 3.5-inch internal hard drive at this time runs beyond 10 watts. A 7200 RPM notebook HD's expends only 2 watts by comparison. Laptops are running at a lesser rate. Currently the LHD spins with a speed of 5,400 RPM to 7,200 RPM. Using the advent of noise-reduction - technologies are launched so that a user can be sure "stealth" like laptop hardrives.

Due to enhanced shock protection technologies being launched, LHD's have a higher shock tolerance limit as compared to typical drives. Do you know a notebook computer which works on 7,200 RPM can endure a shock load larger than 200 Gs through process, while only half of it i.e. 100 Gs is enough for malfunction in desktop PCs hard drives?

This expansion in memory is attributed to CP technology or "compact profile" which could now increase both platter and the volume of platters within the hard drive.
