The NetApp X342A-R6 (also cross-referenced with OEM Seagate part ST1200MM0129) is an enterprise-class 1.2TB SAS hard disk drive (HDD) in 2.5-inch SFF (Small Form Factor) with a 12 Gbps SAS (SAS-3) interface and 10,000 RPM spindle speed.

This is a high-performance, tier-1 enterprise SAS HDD from Seagate’s Enterprise Performance 10K HDD family (specifically the ST1200MM0129 model from the v7/v8 series), rebranded and fully certified by NetApp for use in FAS/AFF storage systems, E-Series, and other NetApp platforms.

It is optimized for low-latency random I/O, high IOPS, and reliable 24×7 operation in demanding workloads such as databases, virtualization, VDI, OLTP, transactional systems, boot/OS volumes, and primary/performance storage tiers where speed and responsiveness matter more than maximum capacity per drive.

The drive features:

  • Dual-port SAS for redundancy and multipathing in high-availability configurations
  • 256 MB cache buffer for improved burst and sustained performance
  • Advanced rotational vibration safeguards to maintain stability in dense multi-drive shelves
  • 512e (512-byte emulation / Advanced Format) sector format for broad OS/RAID compatibility

In NetApp deployments, the X342A-R6 is commonly used as a performance tier drive in FAS/AFF hybrid arrays, E-Series storage, or as a replacement/spare in 2.5" disk shelves (DS224C, DS2246, etc.) — especially in configurations needing high random IOPS alongside higher-capacity NL-SAS drives.
