3D QLC
Western Digital has introduced its new series of SSDs aimed at mainstream PCs, which combine high performance and low cost. The Western Digital PC SN5000S family of DRAM-less drives uses the company's 3D QLC NAND memory and an in-house-developed platform, so the SSDs promise to be relatively inexpensive. Meanwhile, their sequential read performance reaches 6,000 MB/s. Western Digital's PC SN5000S drives are based on the company's latest in-house controller, which supports a PCIe 4.0 x4 host interface and BICS6 3D QLC NAND memory. The controller fully supports Western Digital's nCache 4.0 HybridSLC technology with endurance monitoring to ensure decent performance, RSA-3K and SHA-384 encryption, and TCG Opal 2.02 and Pyrite security capabilities. On the capacity side, Western Digital's PC SN5000S drives will be available in 512...
