The new launches PBlaze5 520 Low Power Series NVMe SSD, which adopts the industry-leading 96-layer 3D NAND, providing 2.5-inch U.2 and Half Height Half Length (HHHL) form factor. To realize flexible deployment, PBlaze5 520 series capacity range from 1.6TB to 3.84TB. PBlaze5 520 series enterprise SSD provides green storage options to fully meet the demand of cloud computing, internet, finance, telecommunications, artificial intelligence and other industries for rapid access to massive data.
PBlaze5 520 series SSD adopts 8-channel architecture and can provide up to 520K IOPS and 3.3GB/s bandwidth, typical and idle power is lower to 9W and 4W. With sustained performance and superior energy efficiency, PBlaze5 520 series provides high-speed and green access solutions formodern data centers.
PBlaze5 520 series supports NVMe-MI, which is designed to provide a common interface for inventory, monitoring health status, configuration, and change management, especially for the large-scale SSD deployment user scenario.
PBlaze5 520 series supports S.M.A.R.T and capacitor health check for diagnostic testing of drive functionality.
PBlaze5 520 series supports dual-port function and allows access via two ports simultaneously,which solves the single-path failure, ensures continuous data access and meets enterprise high availability requirement.
To satisfy continuity of enterprise critical business and reduce the complexity of large-scale SSD upgrade operations in data center, PBlaze5 520 series NVMe SSD supports feature firmware upgrade without reset, enabling complete firmware upgrade without stopping businesses or shutting down systems.
The Variable Sector Size (VSS) transfers user data with metadata. On the premise of ensuring high consistent performance, VSS further guarantees high data reliability requirements for storage systems and distributed file systems.
