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 1DWPD over 5years and 3.2TB, 6.4TB, 12.8TB at 3DWPD over 5 years (under JESD219 workload). All models come in 2.5”U.2 form factor.
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.
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.
PBlaze6 6920 Series supports Weighted Round Robin (WRR), meaning that the SSD can process commands depending on the priority of I/O commands set and assigned by the host. WRR provides differentiated I/O services for the scenarios where applications with different performance requirements share storage devices.
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.
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.
