HDD Markets and Technologies
The mature but highly dynamic hard disk drive (HDD) marketplace consists of multiple segments—consumer, mobile, desktop, enterprise—each with very different storage requirements. Marvell's comprehensive suite of storage technologies power solutions for each market, meeting their specific requirements head-on with innovative targeted, high-performance, power-efficient technologies:
The Marvell Read Channel products use advanced mixed-signal and digital signal processing technologies. Marvell technology incorporates an efficient error correction scheme in addition to advanced digital filtering and data-detection techniques. These products allow customers to achieve high areal density and high data reliability in addition to fast data transfer rates for their HDDs. Marvell read channel products are designed in digital CMOS processes and use custom digital and analog blocks running at very high frequency with low power consumption.
Marvell's Central Processing Unit (CPU) technology is at the heart of our HDD system-on-chips (SOCs). Marvell's CPU technology is compliant with the ARM instruction set, which is supported by a global ecosystem of developers and engineers. As one of a few select companies to hold a full ARM architecture license, Marvell is uniquely positioned to leverage the pervasiveness of the ARM architecture. Marvell's superscalar, dual-issue, out-of-order execution CPUs are among the most advanced in the world. They contain advanced three-level branch prediction, a variable stage pipeline, and an integrated memory controller, providing unmatched high-end performance and meeting low-power consumption requirements.
Marvell's high-performance transceivers support SATA, SAS, and USB HDD interfaces. This highly flexible technology offers high noise tolerance and low jitter with minimal power consumption. Plus, Marvell's many years of experience in the design of transceiver technology ensures a high level of compatibility in all applications.
Due to government regulations and a high concern about data security, nearly all HDDs need to support on-drive encryption. Marvell's cryptographic solution is comprised of high-speed AES engines for encryption of data-at-rest, and a hardware cryptographic module that provides a secure and flexible environment for implementing various data access control standards, including TCG and IEEE.
Marvell offers a complete line of preamplifier integrated circuits (ICs) for consumer, mobile, and desktop HDD storage systems. Our standard CMOS- and SiGe-based preamplifier products provide low-power consumption, high-performance and cost-effective solutions for these market segments. The Marvell preamplifier families are designed for use with the latest TMR (Tunneling Magneto-Resistive) and PMR (Perpendicular Magneto-Resistive) read/write head technologies with advanced fly-height control. All Marvell preamplifier products are certified lead-free, halogen-free, and ROHS compliant.
HDD Motor Controllers
Utilizing standard CMOS and high-voltage MOS technologies, the Marvell family of motor controllers provides extremely power efficient and cost-effective solutions for next-generation consumer, mobile, and desktop HDD storage systems. Marvell motor controller's advanced digital, high-efficiency architecture enables low acoustic noise and low-power consumption for consumer and mobile applications, as well as high-performance desktop and server environments. Marvell's latest desktop and mobile motor controller products support dual-stage actuator (DSA) technology for future generation high-capacity HDDs. All Marvell motor controllers include integrated power management and voltage regulators for the HDD storage system, as well as shock, vibration and/or free-fall sensor supports, and are certified lead-free, halogen-free and ROHS compliant.
