Western Digital has introduced the WD Blue SN550 line of M.2 NVMe SSDs. It’s about the offspring of the WD Blue SN500 line, as they come with new controllers that use PCI-Express 3.0 x4, reports TechPowerUp.
The controller was created by Western Digital and SanDisk, and is based on the same architecture as the WD Black SN750, but without DRAM and has fewer flash channels. WD implements the 96-layer 3D TLC NAND flash and wants the SSD to compete with QLC NAND-based models such as the Crucial P1.
WD Blue SN550 M.2 NVMe SSDs sell for $55 for the 250GB model, $65 for the 500GB and $99 for the 1TB variant. All three models have increased PCIe bandwidth, with data read speeds up to 2400 MB/s. When it comes to recording speeds, they range up to 950 MB/s for the 250 GB model, up to 1750 MB/s for the 500 GB model, and 1950 MB/s for the 1TB variant.
All SSDs have a five-year warranty and TBW durability of 150TB to 600TB depending on the model.
