The NetApp X357A (also listed as NetApp 3.8TB SAS 12G SFF SSD in many reseller and documentation references) is an enterprise-class 3.8TB SAS solid-state drive (SSD) in 2.5-inch Small Form Factor (SFF, 15mm z-height) with a 12 Gbps SAS (SAS-3) interface.

This is a high-capacity, read-intensive / mixed-use SAS SSD from NetApp's validated drive portfolio, typically an OEM-branded version of the Seagate Nytro 3332 or 3331 series (common OEM model ST3840FM0078 or similar), optimized for high IOPS, low latency, and reliable 24×7 operation in demanding storage workloads.

It is designed for use as a performance tier, cache drive, metadata acceleration, or general-purpose SSD in NetApp FAS/AFF hybrid and all-flash arrays, providing significantly faster random read/write performance than 10K/15K HDDs while offering much larger capacity than earlier 1.6TB–1.92TB SAS SSDs.

Key features include:

  • Dual-port SAS for redundancy and multipathing in high-availability configurations
  • Power-loss protection (PLP) via onboard capacitors to flush in-flight writes during power loss
  • Advanced ECC and end-to-end data protection for enterprise-grade integrity
  • Large DRAM cache for excellent burst performance
  • 512e (512-byte emulation / Advanced Format) sector format for broad compatibility

In NetApp deployments, the X357A is commonly used in FAS/AFF hybrid nodes (e.g., FAS8300, FAS8700, FAS9000 series) and all-flash AFF systems (e.g., AFF A-series) — particularly in 24-drive or 48-drive 2.5" shelves (DS224C, NS224) — for high-performance tiers, caching, or replacing smaller SSDs in existing arrays
