About Walton WS21TBD

The Walton WS21TBD 1TB is a high-performance M.2 NVMe SSD designed to provide a significant speed boost for both desktop and laptop users. Utilizing the PCIe Gen 3.0 x4 interface and the NVMe 1.3 protocol, this drive is a versatile solution for gamers, content creators, and professional multitaskers who require more than what traditional SATA drives can offer.

The WS21TBD delivers impressive sequential read speeds of up to 3500 MB/s and write speeds reaching 3000 MB/s. This ensures that system boot times are reduced to seconds, and large file transfers—such as 4K video projects or massive game libraries—are handled with ease.

The standout feature of this specific model is the integrated DRAM Cache. Unlike "DRAM-less" SSDs that use a portion of the system’s RAM (HMB) or rely solely on NAND flash for mapping tables, the dedicated DRAM chip on the WS21TBD allows for:

Faster Data Mapping: Quicker access to the drive’s "map," resulting in lower latency.

Sustained Performance: Better performance during heavy, long-term write operations.

Extended Lifespan: Reduced wear on the NAND flash, as the DRAM handles frequent small metadata updates.

Designed in the standard M.2 2280 form factor, it fits easily into most modern motherboards and thin-and-light ultrabooks. It uses 3D TLC NAND technology, balancing density and endurance. With features like LDPC ECC (Error Correction Code) and Trim support, the drive maintains data integrity over time.
