Overview
ATP's Industrial Enterprise Gen4 NVMe SSD line is aimed at edge servers deployed where conditions are uncontrolled — wide temperature swings, vibration, dust and long service intervals — without giving up the quality-of-service guarantees that enterprise workloads require. ATP positions the family as carrying industrial endurance and build quality alongside enterprise-class random read/write performance, low latency and constant availability.
The N651Sie family spans three form factors on a PCIe Gen4 x4 NVMe interface: M.2 2280 from 240 GB to 1.92 TB, and U.2 and E1.S variants from 960 GB up to 7.68 TB. Sequential performance reaches 6,450 MB/s read and 6,100 MB/s write, with random throughput up to 1,250 KIOPS write and 1,100 KIOPS read on the M.2 form factor. Endurance is 1 DWPD as standard, with 2 and 5 DWPD configurations available through project engagement — a structure that suits boot drives, mixed-use drives and data storage drives from the same validated design.
Reliability engineering is the differentiator. The drives use MCU-based power-loss protection with Level 4 data-in-flight coverage, end-to-end data path protection, an uncorrectable bit error rate below 1 sector in 10^17 bits read, and a 99.9999% QoS target of under 80 µs read and under 30 µs write latency. They operate from -40°C to 85°C case temperature, tolerate 1,500 G half-sine shock and 16.4 G sine vibration, and carry a 5-year warranty with a data retention specification of one year at 55°C after 100% of P/E cycles are consumed.
Key Benefits
-40°C to 85°C industrial temperature range for uncontrolled edge environments. Three form factors, one design — M.2 2280, U.2 and E1.S up to 7.68 TB. Level 4 MCU-based power-loss protection with end-to-end data path protection. Tight QoS — 99.9999% at < 80 µs read / < 30 µs write. Flexible endurance — 1 DWPD standard, 2 or 5 DWPD by project. 5-year warranty and 3,000,000-hour MTBF.
Applications
Edge servers and edge AI inference nodes, industrial automation and factory-floor control, networking and telecom infrastructure, automotive and transportation systems, defense and aerospace platforms, and any deployment needing wide-temperature NVMe storage with enterprise QoS.
