Samsung today announced two new editions to its S Series external hard drive line up; the 3.5-inch 2TB (Terabyte) S3 Station and the 640 Gigabyte (GB) 2.5-inch S2 portable.

These two new family members strengthen Samsung?s external drive portfolio of 1.8", 2.5" and 3.5" drives. Samsung?s hard drive line up, including S2 Portable 640GB, S1 Mini and STORY Station, will be demonstrated in Hall 20 at IFA.

Originally only available in capacities up to 500GB, the new edition to the S2 Portable lineup at 640GB capacity can store data equivalent to 128,000 digital images, 160,000 MP3 music files, or 77 hours of high definition movies.

Designed for large data file back-up of desktop PCs, the 3.5-inch S3 Station is available in up to 2-Terabyte (TB) data storage capacity and comes in a classic piano black glossy casing with a space-saving footprint to conserve desk space.

Both new hard drives offer the same security features in other S2 Portable and S1 Mini drives, such as Auto Backup, SecretZone, and SafetyKey.

The high 640GB density S2 Portable features a high-speed USB 2.0 interface and receives power supply through its main USB port for added user convenience.

The 640GB S2 Portable is available in September and the S3 Station will be available early next year.
