Samsung M60 Series HM120JC 120GB IDE 5400RPM 8M 2.5" Overview Digitall Mobility with the Most Reliable 2.5 inch Mobile Hard Disk Drive 120GB 5400 RPM 8MB Buffer Memory ATA 100 Interface High Capacity HDD High-capacity HDD to Increase Productivity for Professionals Typically, 10 Gigabytes is required to produce a new catalogue for backup files. When several persons are working together, it is more efficient and convenient to keep the backup files on the HDD rather than on other media, such as CD RW media and floppy disks. Therefore, the capacity of the HDD can directly affect the productivity levels of graphic arts professionals, such as graphic designers. NoiseGuard Samsung has developed and applied NoiseGuard™ technology that is a combined technology to eliminate each noise source or to minimize energy transmission. First, modification of the spindle motor's design minimizes the noise source. In addition, the cover is designed to optimize the flow of air. The Damper utilizes vibration absorbing material, installed on the area of highest density, which maximizes the transmission of energy to the outside.  SilentSeek Samsung set out to minimize the data seeking noise that has always irritated users, we have developed and applied SilentSeek™ technology, which makes the movement of the head actuator much smoother. While other competing technologies, such as the AAM option, cause performance degradation to lower the noise level, Samsung's SilentSeek™ technology causes virtually no degradation in performance. ImpacGuard ImpacGuard™, Samsung's patented technology, is designed to prevent any head actuator vibration during a non-operating environment, which reduces the possibility of collision between the head and the disk even further. Besides, HDD parts can also fail due to corrosion or contamination. Samsung analyzed and eliminated these kinds of problems, at the source, and in advance, by applying the best failure analysis technology adapted from our experience in the semi- conductor business. For example, the microscopic pin holes on the disk surface causes corrosion, which then causes one type of hardware failure. Samsung analyzed this fact to solve the problem in cooperation with our disk component suppliers.     Formatted Capacity = 120G Ultra ATA - 100 FDB(Fluid Dynamic Bearing) Motor Load/Unload Technology GMR Head Technology with Wireless Suspension Design SilentSeek Silentec Hybrid Latch Technology   Specifications:   Drive Configuration Interface ATA-6   Buffer DRAM Size+2 8 Mbytes   Bytes per Sector 512   Performance Specification Read Seek Time(typical)     Track to Track 2 ms   Average 12 ms   Full Stroke 22 ms   Average Latency 5.6 ms   Rotational Speed 5,400 rpm   Data Transfer Rate     Media to/from Buffer (max.) 495Mb/s   Buffer to/from Host(max.) 100MB/s   Drive Ready Time(typical) 4 sec   Reliability Specification Non-recoverable Read Error 1 sector in 1014 bits   MTBF 330,000 POH   Controlled Ramp Load/Unload 600,000   Acoustics(Average Sound Power) Idle     1-Disk
