Sandisk’s new Optimus SSD line-up replaces retired WD color-based models — new Optimus, GX, and GX Pro tiers for 2026

Sandisk Optimus SSDs.

Western Digital, known for producing some of the best SSDs, spun off its flash business to Sandisk last year. Following this move, Sandisk has audaciously retired WD’s iconic color-coded SSD branding, such as WD Black or WD Blue, and introduced the all-new Optimus line-up, engineered for gamers, creators, and professionals seeking peak performance.

Optimus is a name woven deeply into the fabric of Sandisk’s history. The journey began in 2013, when Sandisk acquired SMART Storage Systems. The acquisition brought the Optimus product line into Sandisk’s portfolio, further elevating its presence in the enterprise storage arena. The last product that came from the Optimus line was the Sandisk Optimus Max in 2014. The Optimus line-up entered a period of dormancy as Sandisk had seemingly abandoned the series. Now, in a move that bridges past and future, Sandisk has revived the legendary Optimus brand for its consumer SSDs.
