In the world of 3.5” desktop hard drives, most manufacturers have brought to market drives with capacities of 1TB, 1.5TB, and even 2TB. Sadly, these cannot be put into laptops or MicroPCs like the Mac Mini or ASUS Eee PC very easily, leaving those of us in the portable world relying on external disks " or home servers - for our mass storage needs. Most laptops ship with paltry drives... our test mule shipped with a laughable 80GB drive. A quick peruse of the Internet shows that most OEMs are shipping their laptops with drives in the 160GB to 250GB range. They do however, offer larger capacity drives with a larger price tag. If you’re like most of us, with large music and video libraries, you desperately need the extra storage space, but you want it without having to lug around a bulky external drive or the added extra expense.
