PBlaze7 7940 E1.S — The Optimal Choice for Edge Computing and Storage

Customers are always seeking larger capacity and better performance at the same cost.

 

With the rapid evolution of digital technologies, digital infrastructure is being upgraded at an accelerating pace, and edge computing has become a critical complement to cloud computing. Thanks to the lower latency advantage brought about by proximity network transmission, more and more data is being collected, processed and analyzed in real time at locations close to the data source, and making the landing of applications such as automated driving, telemedicine, industrial control, AR/VR, etc. a reality.

 

• It takes just 16.7 milliseconds for the human eye to recognize a frame of an image.

 

• Top F1 drivers react within 156 milliseconds from visual input to physical response.

 

• A 2,000-kilometer signal transmission, even through optical fiber, requires at least 10 milliseconds — adding protocol overhead, switches, and other network elements, the real latency can exceed 20 milliseconds!

 

 

More transmission nodes and longer transmission distances also increase the risk of delay jitter and even data transmission interruption. Meanwhile, the explosive growth of data demands that edge servers not only offer powerful computing capabilities but also highly efficient and reliable storage to support low-latency, high-bandwidth local data processing.

 

Edge environments are often constrained by space, power consumption, and maintenance limitations. While 2.5-inch enterprise SSDs are widely used in data centers, their size, thermal management, and scalability are increasingly inadequate for edge computing scenarios. On the other hand, M.2 SSDs offer a smaller form factor but fall short in performance and lack critical enterprise features like hot-swapping — making them unsuitable for mission-critical edge applications.

 

A new storage form factor is becoming an industry consensus - E1.S - and is being recognized as one of the optimal standards for edge computing and storage.

Why E1.S Stands Out for Edge Applications

 

As one of the next-generation enterprise SSD form factors, E1.S is specifically optimized for high-density deployments and edge scenarios, offering the following key advantages over traditional 2.5-inch SSDs:

 

• Compact size — less than half the size of a 2.5-inch SSD — allowing more SSDs to be deployed in limited server space, significantly increasing overall storage capacity and resource utilization.

 

• Optimized thermal performance — with native heatsink support, E1.S can better handle high temperatures and restricted airflow in edge environments, ensuring long-term stable operation while delivering far superior performance compared to M.2 SSDs.

 

• Rich enterprise-grade features — supporting hot-swapping, dual-port access, power-loss protection, out-of-band management and more — enabling fast SSD replacement and maintenance while reducing operational costs and risks.

 

 

 

 

 

PBlaze7 7940 E1.S — Empowering Edge Storage Evolution

 

As a highly recognized enterprise PCIe 5.0 SSD, the Memblaze PBlaze7 7940 series not only inherits the family’s hallmark high performance and reliability but has also been fully optimized for edge computing, AI, and other emerging workloads:

 

• Leveraging the PCIe 5.0 interface, it delivers up to 14 GB/s sequential read bandwidth, 10 GB/s sequential write bandwidth, 2.8 million IOPS for 4K random reads, and 500K IOPS for 4K random writes — representing a significant performance leap over previous-generation products.

 

• Exceptional QoS and stability — ensuring a superior data service experience even in extreme environments.

 

• Comprehensive enterprise-grade features — including end-to-end data protection, power-loss protection, secure erase, out-of-band management, and TCG Opal support — safeguarding business continuity and data security.

 

•  Industry-leading energy efficiency — delivering lower power consumption and heat generation, meeting the demands of high-density edge deployments and long-term stable operation.

 

PBlaze7 7940 E1.S 15.36TB

 

Most notably, the PBlaze7 7940 E1.S redefines industry expectations for E1.S capacity — pioneering a groundbreaking single-drive capacity of 15.36TB, far surpassing the mainstream 3.84TB to 7.68TB range of enterprise E1.S SSDs. It perfectly combines high performance and large capacity in edge storage scenarios, providing customers with superior scalability and resource efficiency.

 

Within limited rack space and power budgets, the PBlaze7 7940 15.36TB E1.S offers the optimal balance of performance and capacity for edge computing, smart manufacturing, AI inference, content delivery, and more — making it the best choice for driving the evolution of edge storage.
