Memblaze announces their NVMe SSD "PBlaze5 920" series that uses 96-layer 3D eTLC NAND, with volume sizes up-to 7.68TB. Not just that, they make use of a cx8 PCIe connection, alloing them to run to 5.9 GB/sec and do 970,000 IOPS.



PBlaze5 920 Series NVMe SSD adopts 96-layer 3D eTLC NAND with a capacity up to 7.68TB, and comes in form factors of 2.5-inch U.2 and HHHL add-in card. PBlaze5 920 Series consists of 4 groups of SKU -PBlaze5 D920, PBlaze5 C920, PBlaze5 D926 and PBlaze5 C926.

Memblaze PBlaze5 920 Series NVMe SSD offers up to 5.9GB/s read bandwidth and 970,000 read IOPS, with read and write latency lowering to 90μs and12μs respectively. With superior performance, perfect data protection, good compatibility, and user experience, as well as abundant enterprise-class features, PBlaze5 920 Series NVMe SSD enables customers to build high-speed, high-reliability, and flexible storage solutions for their mission-critical applications.

  • 96-layer 3D NAND, providing up to 7.68TB in single disk
  • Up to 5.9GB/s throughput
  • Firmware Upgrade without Reset
  • 32 Namespaces and 32 encryption keys
  • QoS improvement with Quota by Namespace
  • T10 PI End-to-End Data Protection

  • Up to 8TB/s enterprise TRIM function
  • Support Dual Port and NVMe Reservation
 
 

Firmware upgrade without reset

The upgrade of traditional firmware requires a cold restart of the server before the restart of each module of the business system, which is complicated and error-prone. Memblaze PBlaze 920 Series NVMe SSD supports firmware upgrade without reset. Even if there are I/O operations in the business system, the firmware upgrade can still be completed without stopping businesses or shutting down systems, which guarantees continuous storage system services and greatly simplifies the operation and maintenance process and reduces the IT system operation & maintenance difficulty and cost.


Variable sector size management

The Variable Sector Size (VSS) transfers user data with metadata.  Memblaze PBlaze5 920 Series supports 512, 520, 4096, 4104, and 4160 bytes Variable Sector Size, which means 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.
