In a bold move unveiled at CES 2026, SanDisk Portable Extreme SSD-maker SanDisk announced that its beloved WD Black and WD Blue SSD product lines are being rebranded under a single new family name SanDisk Optimus. This marks the end of Western Digital’s long-standing color-coded SSD branding and the beginning of a fresh chapter for high-performance storage under the SanDisk banner.
This change isn’t about “new tech” so much as clarity, unity and focus simplifying how consumers identify and choose internal SSDs for gaming, creative work, and everyday computing.
The Big Shift: Why the Rebrand?
SanDisk, which spun off from Western Digital in early 2025, now operates independently and is reclaiming its legacy in flash storage. As part of its strategy, the company announced that its SSD lineup will drop the WD Black and WD Blue names historically trusted by PC builders and tech fans in favor of a unified brand structure called SanDisk Optimus.
These iconic names won’t disappear overnight from store shelves, but going forward, new SSD models and packaging will carry Optimus branding worldwide, with availability expected to expand through 2026.
What’s Changing and What Isn’t
The rebranding is largely nominal, meaning the underlying technology powering the SSDs remains the same high-speed, reliable performance users expect. SanDisk’s press materials emphasize that performance, quality and support will remain consistent through the transition.
Here’s how the old product tiers map to the new Optimus lineup:
SanDisk Optimus (Mainline)
- Replaces WD Blue SN5xxx series
- Targeted at everyday users and creators who want balanced speed and capacity.
- Example: WD Blue SN5100 NVMe PCIe 4.0 Internal SSD would become a SanDisk Optimus 5100 model under the new name.
SanDisk Optimus GX (Mid-Tier / Gaming)
- Replaces WD Black (mid-range) SN7xxx series
- Built for gamers and enthusiasts who want faster load times and balanced endurance.
SanDisk Optimus GX Pro (Flagship / Enthusiast)
- Replaces WD Black SN8xxx series
- The top tier aimed at creators, developers, high-end gamers and performance rigs.
In short, the same trusted storage tech you’ve known just under a refreshed and more intuitive product structure.
What SanDisk Says
According to the official press release, the Optimus rebrand was designed to:
Make it easier to find the right SSD for your needs whether that’s gaming, creative work or daily computing.
Provide a clear, tiered lineup that matches performance expectations.
Expand SanDisk’s identity as a standalone leader in flash storage.
SanDisk executives emphasised that the technology and quality customers rely on aren’t changing just the logos and naming scheme.
What This Means for You
If you’re planning to buy or upgrade internal storage in 2026 and beyond, here’s how the transition plays out:
Branding & Packaging
- New SSDs will list SanDisk Optimus, Optimus GX, or Optimus GX Pro on the box.
- WD Black and WD Blue names will gradually disappear from new models.
Performance & Hardware
- No changes in specs or performance just because of the name change. The same NVMe controller, NAND flash and firmware continue to power these SSDs.
Warranty & Support
- Existing SSDs bought under the WD branding retain their original warranties and support through SanDisk.
Shopping Tips
- During the rebrand rollout, you might still find WD Black or WD Blue units on shelves at retailers before Optimus stock fully replaces them.
- The change might prompt discounts on remaining WD inventory as stores clear old stock.
Why This Matters
For years, WD Black and WD Blue SSDs were among the most recognizable storage brands, trusted by builders and gamers for speed and reliability. Now, SanDisk is carrying that legacy forward with a modern, segmented brand hierarchy that aims to help shoppers more easily navigate performance tiers.
Think of it as moving from a simple two-color label system to a broader roadmap of performance tiers from everyday productivity to pro-grade performance all under the SanDisk umbrella.
Whether you’re upgrading the storage in your gaming rig or adding a snappy NVMe drive to your laptop, the SanDisk Optimus family is poised to become the new go-to choice in 2026 and beyond.
- SanDisk Optimus is now the umbrella name replacing WD Blue and WD Black SSDs.
- Products are split into three tiers Optimus, Optimus GX, and Optimus GX Pro for everyday, gaming, and pro use.
- The rebrand begins with new packaging being rolled out through the first half of 2026.
- Performance, warranty and hardware quality remain unchanged from the old WD SSDs
