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.

Platters have two sides. The 1 TB drive would be 3 platters with 6 read-write heads. The 750 GB drive is probably 3 platters with 5 read-write heads (~830 GB capacity, limited by firmware to 750 GB).

And this type of market segmentation is nothing new. Intel's CPUs do the same thing with clock speed (which is why some of their CPUs overclock so well). People may not want the full 1 TB nor pay its price. WD decides to make a 750 GB at a lower price, but finds that the price of re-engineering a 3-platter 250 GB per platter design is rather high. So they just cripple the 1 TB drive to make a 750 GB drive at much lower cost than a brand new 750 GB drive design.
