SanDisk announced the Optimus brand at CES 2026 to replace its WD_BLACK and WD Blue internal SSD lineup. The new naming system organizes drives into three tiers Optimus, Optimus GX, and Optimus GX PRO targeting creators, gamers, and professionals. Products with the updated branding will reach retailers in the first half of 2026.
What’s New
SanDisk introduced the Optimus family on January 5, 2026, at the Consumer Electronics Show in Las Vegas. The rebrand consolidates all internal NVMe SSDs under a single product umbrella. Existing models retain their technical specifications and model numbers but adopt new packaging and naming conventions.
The base SanDisk Optimus tier replaces the WD Blue line, including the SN5100 NVMe SSD, and targets content creators seeking balanced speed and affordability. The Optimus GX line succeeds WD_BLACK gaming drives like the SN7100, prioritizing fast load times and power efficiency. The flagship Optimus GX PRO replaces high-end WD_BLACK models such as the SN8100 and SN850X, designed for AI PCs, workstations, and demanding workflows.
SanDisk also unveiled the Optimus GX 7100M, a compact M.2 2230 variant with read speeds up to 7,250 MB/s and write speeds reaching 6,900 MB/s, optimized for handheld gaming devices.
Why It Matters
The rebrand follows the 2025 separation of Western Digital and SanDisk into independent companies, necessitating the retirement of WD-branded consumer products. Heidi Arkinstall, VP Global Consumer Brand and Digital Marketing at SanDisk, stated the change simplifies product discovery across multiple performance segments.
The three-tier structure addresses a longstanding confusion in the SSD market where color-coded naming (Blue, Black) offered limited clarity about performance differences. By aligning product names with use cases mainstream computing, gaming, and professional workflows SanDisk aims to reduce buyer friction and create room for future expansion into AI-accelerated storage solutions.
Product Lineup Breakdown
| Tier | Target Users | Replaces | Key Models | Use Cases |
|---|---|---|---|---|
| Optimus | Content creators | WD Blue | SN5100 | Balanced performance, everyday workloads |
| Optimus GX | Gamers | WD_BLACK | SN7100, 7100M | Fast load times, power efficiency |

What’s Next

The company emphasized that underlying engineering, quality standards, and warranty terms remain unchanged from the WD_BLACK and WD Blue generations. Additional Optimus variants and capacity options may be revealed as the product family expands through 2026.
