ATP Electronics Introduces Industry’s Best in Class I Temp Operable 8 TB E1.S SSDs


Outstanding 6000+ Sequential Read/Write performance, 1 DWPD for 5 years based on JESD219A standard for Enterprise Workloads, and 1 year data retention with 100% P/E cycles at 55°C

ATP Electronics, the global leader in specialized storage and memory solutions, proudly unveils the N651Si Series E1.S solid state drives (SSDs), which offer best in class performance, endurance, and data retention capabilities for the most demanding applications.

Supporting industrial temperature operating range (-40°C to 85°C) along with hardware power loss protection (HW PLP), the new SSDs offer the highest levels of reliability and total cost of ownership value in harsh environments, making them especially beneficial for mission-critical applications running under extreme temperatures, such as automotive, data logger, data centers, and defense/aerospace.

Engineered for 1U Edge servers, the EDSFF offering with 9.5 mm symmetrical enclosure is available with up to 8 TB capacity and is constructed with 512 Gb prime NAND die176-layer 3D triple level cell (TLC).

Accelerated Performance for Demanding Workloads

ATP Electronics’ N651Si Series E1.S SSDs satisfy the demands of modern data-hungry applications for speed, capacity, and scalability.

Sustained sequential read/write performance of 6100/6000 MB/s ensures high-speed processing and access to critical data. These SSDs leverage NVMe1.4 and the PCIe Gen4 x4 interface to accelerate workloads, maximize throughput, and transform data into actionable insights.

Built to Last Longer: Shattering Endurance Limits

Engineered for 1U Edge servers, ATP’s E1.S SSDs are tested rigorously and comply with JEDEC’s JESD219A standard for Enterprise Workloads.

With a high endurance rating of 1 drive write per day (DWPD)forfive years, the N651Si Series E1.S SSDs can withstand daily writes to their entire 8 TB capacity within the warranty period. This demonstratesthat they can deliver long-lasting performance and exceptional reliability even under the most intense operations.

Anti-sulfur resistors provide enhanced defense against corrosion caused by sulfur.

To ensure supply continuity, the new offerings come with ATP’s five-year longevity support.

Extended Data Retention

When storage devices reach 100% of their rated P/E cycles, data retention can be a challenge. Archived data, which may be crucial for legal and regulatory compliance, continuing corporate operations, intellectual property protection, and other important purposes, may risk corruption or loss if the storage device cannot maintain integrity over extended periods.

N651Si Series E1.S SSDs with 100% P/E cycles, can store data for up to a year at 55°C. This data retention capability is superior to other storage devices with the same P/E cycles.

I-Temp Rated with HW PLP

Using ATP’s Advanced Thermal Management System, the N651Si Series E1.S SSDs deliver excellent thermal performance, making them especially beneficial for mission-critical applications running under extreme temperatures, such as automotive, data logger, data centers, and defense/aerospace.

These SSDs can operate dependably within I-Temp ranges of -40°C to 85°C. When the SSD temperature exceeds the assigned temperature, thermal throttling is activated to prevent damage to both the device and stored data but without sudden drops in performance, thus maintaining balance and sustaining optimal performance.
Hardware power loss protection (HW PLP) makes sure that when a power outage occurs while data is being processed in volatile memory, the data is safely flushed or written to the non-volatile NAND flash, hence preventing data loss or corruption.

Robust Security and Optimized Design

The N651Si Series E1.S SSDs comply with TCG Opal 2.0 and are integrated with AES256-bit encryption for robust protection against data theft and tampering. Optional self-encrypting drive (SED) capabilities with IEEE 1667 access authentication protocol provide an extra layer of security with full-drive encryption and pre boot access protection.

Constructed to fit vertically in a 1U chassis, the N651Si Series E1.S SSDs expand the data storage capabilities of compact systems and 1U servers.

The design also allows airflow to pass through the server backplane, thus offering better cooling efficiency. The E1.S SSDs support hot swapping/hot plugging for easy replacement and maintenance without downtime.
