The PBlaze5 920 Series NVMe SSD helps its customers build effective, flexible and high-performing storage solutions for their mission-critical applications.
The Memblaze PBlaze5 920 Series NVMe SSD is quoted to deliver some impressive reads with up to 5.9GB/s and 970,000 IOPS, while latency is expected to hit just 90μs and 12μs, for reads and writes, respectively. Memblaze indicates that, with this level of performance coupled with its data protection, compatibility, and enterprise-class features, the new PBlaze5 drive will significantly improve overall user experience. This release is a step up from the previous MemBlaze PBlaze5 916.
To address the growing number of multi-application deployment scenarios on a single drive, Memblaze has added “Quota by Namespace” support to the PBlaze 920 series. This is a brand new feature that carries out quota operation to the namespaces of NVMe SSD then selects appropriate namespaces depending on the application priority so that it can optimize and expand the application scenarios. Memblaze indicates that, by creating different namespaces on their new SSD and placing quota limitation on the namespaces loaded with tasks of lower priority, namespaces with high-priority tasks will have access to more I/O resources.
The Memblaze PBlaze 920 Series NVMe SSD offers the handy features of no reboots after firmware upgrades, which can certainly help with continuous storage availability (even if there are I/O operations in the business system). Memblaze adds that this will also help simplify the operation and maintenance process while reducing IT system operation and maintenance costs.
