PBlaze5 520 series NVMe™ SSD


Memblaze delivers PBlaze5 520 series SSD with significant power reduction. The typical power consumption of this Series is only 9W and the standby power consumption is as low as 4W. PBlaze5 520 series provides enterprises with green storage options to reduce rack space, room space, equipment purchases and power consumption, dramatically lower the Capital Expenditures (CAPEX) and Operating Expense (OPEX).








9W Typical Power with Sustained Performance

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 for modern data centers.

NVMe-MI for Out-of-Band Management

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.

Dualual Self-Test

PBlaze5 520 series supports S.M.A.R.T and capacitor health check for diagnostic testing of drive functionality.

High Availability Dual-Port

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.

Firmware Upgrade without Reset

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.

Variable Sector Size Management

The Variable Sector Size (VSS) transfers user data with metadata. PBlaze5 520 series supports 512, 520, 4096, 4104, and 4160 bytes Variable Sector Size, which means an I/Os from service application carry 8 bytes or 64 bytes of metadata simultaneously. On the premise of ensuring high consistent performance, VSS further guarantees high data reliability requirements for storage systems and distributed file systems.
