Samsung HM641JI 2.5" 640GB Mobile Hard Disk Drive

NOISEGUARD
All Samsung-created hard drives are equipped with NoiseGuard technology, making them the quietest drives in the world. Samsung HDDs are equipped with NoiseGuardTM technology which emit significantly lower levels of noise (human-detectable frequencies-1KHz - 3KHz.)

SILENTSEEK
Samsung has developed another unique design called SilentSeekTM technology. SilentSeekTM technology differs from NoiseGuardTM in that it is designed to minimize the acoustic noise generated by the actuator movement, rather than suppressing the emitted acoustic noise. SilentSeekTM technology is designed to minimize the mechanical excitation generated by any resonance, virtually eliminating the source of seek acoustic noise.. By incorporating SilentSeekTM technology, Samsung HDDs achieves approximately 4dBA reduction of seek acoustic noise (sound pressure level). Samsung's proprietary SilentSeekTM technology, when combined with NoiseGuardTM technology, provides the best combination of low acoustics and HDD performance, ideal for today's diverse and demanding HDD applications.

S.M.A.R.T.
Samsung is aware of the importance of data preservation in HDD. SMART (Self-Monitoring Analysis and Reporting Technology) is a product which warns users of the product's defects and informs the users to transfer data to other places. How can a product that alerts you to the defects of HDD prevent data loss before your HDD crashes This product will provide epoch-making and safe PC configuration and prevent the tremendous damages caused by data loss. Samsung SMART will allow the consumers to detect Samsung HDD's defects in advance. SMART is designed to fit the characteristics of peculiar pertinent drive and has better functions than its predecessors because it checks each internal component of HDD.
