New Scorpio Blue drive has 333GB per platter.

The only real benefits of a hard drive over SSD today are the higher storage capacity and the fact that the average hard drive is cheaper than comparable SSDs. As storage capacities increase HDDs, become more appealing to many users.

Western Digital (WD) has announced a pair of new hard drives today called the WD Scorpio Blue in 750GB and 1TB capacities. Both of the drives use the same platters cramming 333GB of storage space each. The drives both have the same 12.5mm form factor meaning that they won’t fit into machines that have 9.5mm drive bays.

WD will also be putting the Scorpio Blue hard drives into external storage solutions like the My Passport Essential SE USB drives along with select notebooks and small form factor desktop PCs. The drives are optimized for cool and quiet operation. The interface used by the drives is the 3Gb/s interface.

"The convergence of the growing mobile computing and digital media trends produces demand for desktop-like capacities in portable devices," said Jim Morris, senior vice president and general manager of client systems at WD. "Our new WD Scorpio Blue drives enable people to take even more of their digital collections with them wherever they go and, realizing the value of their data, back up their notebooks on their My Passport drives."

Features of the Scorpio Blue drives include WhisperDrive making it one of the most silent 2.5-inch hard drives available. ShockGuard combines firmware and hardware features to help the drive reach the highest combined shock tolerance specifications for notebooks. The drives also feature SecurePark that parks the head off the disk surface during spin up, spin down, and when the drive is off. The feature ensures the recording head never touches the disk surface.

The Scorpio Blue 750GB HDD is available now at $189.99, the 1TB drive is only available now in the My Passport Essential SE USB drive for $249.99.

You only use 5 heads instead of 6, giving around 830GB capacity, then limit it to 750GB for marketing/competitive positioning reasons. Reducing the # of heads saves costs. Using only 1 side of a platter allows platters that have significant defects on one side to be utilized rather than scrapped. Reducing the capacity allows platters with more defects to be utilized. Therefore, they can reduce the wasted components and reduce costs.

In reality, most of the 750GB drives will have the exact same, relatively defect free platters as the 1TB drives, they'll just be missing one head and will be limited to 750GB by firmware because 750GB is a "common" size which is easier to market.
