Today Western Digital announced new NVMe SSDs in their WD Gold family. The new SSDs are aimed at small and medium-sized enterprises (SMEs) to help them transition to NVMe storage and all the benefits that come with it such as much higher performance and ultra-low latency. This marks the first NVMe product in the WD Gold family and broadens the company’s overall data center offerings.
NVMe SSDs have really taken off has their price as come down. They offer up to five times the sequential performance of SATA SSDs and can help leverage the advancements in multi-core, multi-threaded CPUs. According to IDC, NVMe unit shipments are expected to exceed 79% by 2023. The introduction of the WD Gold NVMe SSDs, Western Digital is giving customers more options in storage going forward.
The new drives come in four capacities: 960GB, 1.92TB, 3.84TB, and 7.68TB. The SSDs are based on Western Digital’s silicon-to-system expertise, from its 3D TLC NAND SSD media to its purpose-built firmware and own integrated controller. The WD Gold NVMe SSDs are designed for the primary storage in servers delivering superior response times, higher throughput and greater scale than existing SATA devices for enterprise applications. The drives come with a five-year limited warranty and secure boot and secure erase.
