Marvell 88i9441 Soleil-H SATA SSHD Controller
6Gb/s SATA, Dual ARM On-Chip Processors, Encryption
PRODUCT OVERVIEW
The Marvell® 88i9441 is a high performance, low power Solid State Hybrid Drive (SSHD) controller that is highly flexible, enabling
optimization for a wide variety of storage environments. Advanced read/write channel technology with low density parity check
(LDPC) makes Soleil the best choice for high density drives.
Two integrated ARM Cortex-R4 processors allow independent management of host and servo functions, enhancing overall HDD
performance. A third dedicated secure processor supports AES encryption, protecting user data from unauthorized access.
The 6Gb/s SATA host interface supports Native Command Queuing, T10 CRC checking, and the ATA-8 command set, ensuring
high performance, data integrity, and full compatibility with SATA hosts.
