PBlaze6 6920 Series NVMe™ SSD


PBlaze6 6920 Series is developed based on Memblaze's self-developed MUFP (Memblaze Unified Framework Platform), a unified framework platform for the development of all subsequent products of the firm.PBlaze6 6920 Series SSDs feature the PCIe4.0 and 96-layer 3D NAND and support the NVMe 1.4, spans a wide range of user capacity including 3.84TB, 7.68TB, 15.36TB at 1.7DWPD over 5years and 3.2TB, 6.4TB, 12.8TB at 3.6DWPD over 5 years (under JESD219 workload). All models come in 2.5”U.2 form factor.

Sustained Performance

PBlaze6 6920 Series SSDs offer stable performance up to 1600K random read IOPS, up to 7.1GB/s sequential read bandwidth, up to 6.8GB/s sequential write bandwidth, and up to 11μs in write latency. Build-in Scheduler Mechanism realizes Quality of Service (QoS) control to guarantee the consistent performance.

Proven Data Reliability

After years of market-proven, from NAND to link path layer, PBlaze6 6920 series is implemented with patent data protection technology, fully protect enterprise data in a safe and reliable storage environment. Newly added feature device self-test provides S.M.A.R.T and capacitor health check for diagnostic testing of drive functionality on PBlaze6 6920 series.

Ultra-long write endurance

The adoption of NAND flash memory with the highest grade for enterprise TLC NAND, coupled with the 4K LDPC and multiple optimized algorithms, allows PBlaze6 6920 Series to achieve an ultra-long write endurance, which ensures long-term business stability, especially for the application scenarios of read/write intensive and mixed read-write workloads.

Weighted Round Robin

PBlaze6 6920 Series SSD can process commands depending on the priority of I/O commands set and assigned by the host.For traditional round-robin, commands are processed in each queue in turn with equal priority, while WRR processes the applications I/O with different priorities. WRR provides differentiated I/O services for the scenarios where applications with different performance requirements share storage devices.

Collect internal data logs with Telemetry

PBlaze6 6920 Series supports the collection of logs via the Telemetry standard interface. The users can collect the log required by the SSD provider with a standard nvmecli command before sending for further analysis. This function drastically reducing the complexity of log collection and lowering the operation and maintenance costs.

Sanitize

PBlaze6 6920 Series features Enhanced Secure Erase (Sanitize). If NVMe SSD is repurposed or is decommissioned after depreciation, the standard nvmecli command can be triggered to perform Sanitize to completely wipe out the users' data and prevent the recovery of old data with certain tools, protecting the information security of users.
