The Perfect AV Environment with Noiseless Hard Disk Drive

Samsung Hard Disk Drive 2007 Product Guide

here is an emerging trend to produce PCs focused Ton AV, that seeks to maximize the efficiency of the AV function through the Internet. For example, this kind of PC would feature high-performance audio equipment such as 20W 2-way speaker to create better sound effects, and even a built-in PVR function. What if the PC, designed around high end AV features, was found to generate too much noise? It

would be a significant problem.

Major Index of Quality for PC Recently, acoustic noise level has become the major index of quality for many home appliances, such as air-conditioners and refrigerators. The cooling fan of the CPU and HDD are major parts in the PC that generate noise. In case of the CPU cooling fan that generates constant noise in idle mode, recent improvements in design have significantly reduced noise levels. Further, a new PC without a CPU cooling fan has been introduced to eliminate this kind of noise. A HDD usually generates 2.8 to 3.3 Bels in idle mode, and 3.0 to 3.5 Bels in seek mode. This level of noise can cause distraction and annoyance to users, since many of them use their PC in quiet environments, such as at night, where 3.0 Bels or less noise levels are typical.

The Cause of HDD noise The HDD generates different noise characteristics by the frequency level. The biggest source of the noise is the spindle motor which generates vibration from its rotating motor. The vibration is transferred to the outside of the HDD and causes the noise. Also, the flow of air inside HDD caused by disk rotation can create noise. During seek mode, the movement of the head actuator generates a very high- pitched noise, familiar to all PC owners.

Noise GuardTM and SilentseekTM Technologies Samsung has developed and applied NoiseGuardTM 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. Furthermore, to minimize the data seeking noise that has always irritated users, we have developed and applied SilentSeekTM 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 SilentSeekTM technology causes virtually no degradation in performance.

HM120JI, HD501LJ, HD403LJ, HM060HC, HD402LJ specifications

The Samsung MP0402H, HD500LJ, HM040HI, SP2004C, and HD401LJ are notable hard disk drives (HDDs) that emphasize Samsung's commitment to storage technology and performance.

The Samsung MP0402H is a 40 GB hard drive that operates at a spindle speed of 5400 RPM, making it suitable for entry-level laptops and desktops. It employs a SATA interface, which facilitates faster data transfer rates compared to older IDE connections. With its compact 2.5-inch form factor, it offers a balance of size and performance, making it a reliable choice for consumer electronics.

On the other hand, the HD500LJ is designed with higher storage capacity in mind. This 500 GB drive uses a 7200 RPM spindle speed, significantly improving data retrieval times. It is also equipped with a Serial ATA interface, providing enhanced bandwidth and efficiency. This model is ideal for those requiring ample storage for multimedia files or applications, while maintaining robust performance.

The HM040HI reflects Samsung's ongoing innovation with a 40 GB capacity and features similar characteristics to the MP0402H. This HDD is also a 5400 RPM drive, ensuring energy efficiency, which is essential for portable devices. Its low power consumption enhances battery life in laptops, making it a preferred option for mobile users.

The SP2004C further expands on this range with a capacity of 200 GB. Its 7200 RPM speed allows for quick data access, which is especially beneficial for gaming and high-performance applications. This model also maintains a 3.5-inch form factor, suitable for desktop systems, and uses an SATA interface for optimal connectivity and speed.

Lastly, the HD401LJ offers an impressive 400 GB of storage with the same high-performance 7200 RPM speed characteristic of the HD500LJ and SP2004C. Its design caters to users requiring a blend of space and performance, making it appropriate for both creative professionals and average consumers alike.

In summary, these five Samsung HDD models showcase advances in storage technology, offering a range of capacities and speeds. Their combination of SATA interfaces, varying spindle speeds, and form factors ensures there is an option for everyone, from casual users to professional environments. Samsung continues to be a contender in the storage market, marries performance with reliability across its product lineup.
