320GB Scorpio Hard Disk Drive

2.5-Inch | EIDE 100 MB/s | 5400RPM | 8MB Cache
Big capacity for portable computing.
WD Scorpio delivers best-in-class performance with low power requirements comparable to much slower notebook drives. In addition, you'll get the quietest 2.5-inch drive on the market with real-time data protection technology to help keep your data safe.
Massive Capacity
Whether they are in an external drive or a notebook computer, WD's 320GB 2.5-inch drives offer the most available capacity for space-hungry operating systems, plus plenty of room left over for photos, music, and video.

Fast and efficient
Spins at 5400 RPM for fast performance but has power specs similar to slower 4200 RPM drives. Low power consumption yields increased reliability.

WD's exclusive WhisperDrive™ technology with SoftSeek™ algorithms make this the quietest 2.5-inch hard drive, regardless of spin speed.

WD's ShockGuard™ technology protects the drive mechanics and platter surfaces from shocks. WD's DuraStep Ramp™ locks the heads in a secure position away from the disk to provide another layer of protection when the drive is not in use. Utilizing the most technologically advanced material available, the drive can perform a minimum of 600,000 load/unload cycles without contamination - up to twice the performance of its competitors.

WD Scorpio's rigid stainless steel top cover withstands more than 5 pounds of pressure - nearly 1.5 times the industry average - without pinching vital internal components.

Rating: 5/5 OWC 320GB saves my PowerBook G4 August 18, 2011 Just purchased a 320GB IDE/PATA 2.5 internal HD for my PowerBook G4 and the little OWC toolkit. Followed your excellent tutorials on youtube. It was a detailed process, but each step wall fully documented with nothing left out. Everything went as the video described. THANK YOU VERY MUCH! I restored the new disk from a backup and presto my PowerBook G4 was as good as new. Actually it is better than new as this disk is much faster and larger than the original. Great value and Great service. Thank You!

I would recommend this item to a friend!

Rating: 5/5 Just as fast as a 7200 RPM Mobile Drive June 24, 2011 Because this 2.5" Mobile ATA drive has denser platters, like what you would find on a 2.5" mobile SATA drive, this 5400 mobile ATA drive is just as fast as a 7200 RPM mobile drive. On my Finder "Duplicate" copy tests, this drive is faster on my 1.67 GHz Powerbook G4 than my Seagate 3.5" 7200 RPM Altra ATA 100 drive on my Dual 1.25 GHz G4 desktop. This 320 GB Western Digital "Scorpio" maxes out your ATA platter hard drive performance on your late revision Powerbook G4.
