SanDisk X300DC SSD

Get the best of both worlds: secure your data and speed it up.


Based on state of the art 1Ynm TLC flash technology, the SanDisk X300DC SSD delivers high read performance with high reliability and low power. It features nCache™ 2.0 technology, SanDisk’s next generation tiered caching technology, designed to improve SSD responsiveness for burst write workloads.


With the improved cost structure introduced in X300DC SSD and the use of SanDisk’s most manufactured flash technology, there is continuity of supply, better flash availability, improved TCO, and shorter ROI times.

nCache™ 2.0 Technology

nCache 2.0 uses a combination of both SLC and TLC flash blocks to improve endurance, increase efficiency, and boost performance. By writing all the data to SLC blocks first, the write amplification on the TLC blocks is reduced. The new On Chip Copy (OCC) mechanism then independently copies the SLC cache blocks into the TLC blocks in main storage, thus offloading the burden from the controller and DDR resources. This leaves the controller and DRAM cache free for other tasks.
