Product Features
Technical Overview
The SN7100 leverages PCI Express NVMe 4.0 x4 interface technology to achieve sequential read speeds up to 7250 MB/s and write speeds up to 6900 MB/s. These transfer rates significantly outperform SATA-based SSDs and earlier PCIe generations, reducing file transfer times and application loading delays.
Random 4KB operations reach 1,000,000 IOPS for reads and 1,400,000 IOPS for writes, ensuring responsive performance during mixed workloads and multitasking scenarios. The drive maintains consistent performance across sustained operations thanks to advanced NAND management and thermal design.
This section brings together practical product details such as Storage Capacity, Platform Supported, Maximum Read Transfer Rate, Maximum Write Transfer Rate, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
