The SSD controller is the brain of your SSD, managing NAND communication, error correction, wear leveling, and performance. Choosing the right controller for your OEM product is essential for achieving your target specifications and price point.
The leading SSD controller manufacturers include Phison, Silicon Motion (SMI), Maxio, InnoGrit, and Marvell. Each has different strengths: Phison leads in compatibility and features, SMI in power efficiency, Maxio in cost-effective solutions, and InnoGrit in enterprise performance.
Key controller specifications include supported PCIe generation (3.0/4.0/5.0), NAND channel count (4 or 8 channels affecting performance), DRAM support (affecting random performance), error correction (LDPC for modern NAND), and security features (AES encryption, TCG Opal).
Your OEM partner’s controller relationships affect pricing and supply stability. ORION works with multiple controller suppliers to optimize performance and cost for each OEM project.
