High-speed, high-capacity 2.5-inch drives (the ones mainly used in laptops) are few and far between. Most large-capacity laptop drives run at 5,400rpm or 7,200rpm, and while you can get super-speedy Serial Attached SCSI (SAS) 2.5-inch drives, they usually come in capacities lower than 250GB. But according to the road map of storage distributor Compellent, faster drives with plenty of room may soon be on the way.
Though no manufacturer is named, the road map lists a 900GB, 10,000rpm 2.5-inch drive that will be available in an unspecified near future. For extreme speed freaks, there's also a listing for a 300GB, 15,000rpm drive. It's unclear if these would be SAS drives, or SATA-based, and there's no mention of pricing.
While such drives may be designed for the enterprise, we all know that such high-performance parts will move to the enthusiast market for those demanding the fastest of everything. You'll no doubt pay a premium when and if these drives become available, but they may give notebook hard drives a little more juice as fast, but pricey solid state drives continue to grow in popularity.
