At CES 2026, Sandisk unveiled a major rebranding of the Western Digital SSD portfolio, introducing the 'Sandisk Optimus' series. This strategic move consolidates the former WD_BLACK performance line and WD_BLUE mainstream drives under a unified brand identity. The new lineup includes the Optimus (replacing WD_BLUE), Optimus GX (replacing WD_BLACK SN7100), and the flagship Optimus GX PRO (replacing WD_BLACK SN8100).

The Optimus GX PRO specifically targets high-end gaming and workstation use cases, delivering PCIe 5.0 speeds of up to 14.9 GB/s read and 14 GB/s write. Available in 2TB and 4TB capacities, these drives maintain the legacy part numbers to ensure continuity for the gaming community that has long valued WD_BLACK's performance. This rebranding is significant as it signals a unified future for Sandisk's storage solutions, streamlining the product stack while retaining the performance metrics enthusiasts expect.

The familiar black and red aesthetic continues, reinforcing brand recognition.
