Silicon Power P34A80 2000GB

The Silicon Power P34A80 2TB is a high-performance NVMe storage solution utilizing the PCIe 3.0 x4 interface to deliver near-saturation bandwidth for the generation. Originally architected as a reference design based on the Phison PS5012-E12 controller paired with Toshiba BiCS 3D TLC NAND and a dedicated DDR4 DRAM cache, the drive relies on a traditional 8-channel controller design to maintain high IOPS and sustained throughput. While the 2000GB capacity offers high density, the drive’s technical identity is defined by its volatile Bill of Materials (BOM), meaning the specific controller and NAND combination may vary depending on the manufacturing batch while targeting the same top-tier Gen3 performance specification. Field notes indicate revisions have used Phison E12, SM2262EN, Phison E12S, and Realtek RTS5762 controllers, with Realtek-based variants tending to exhibit higher operating temperatures and different sustained write profiles; NAND suppliers have included Kioxia (Toshiba), Micron, and YMTC, affecting SLC caching behavior and post-cache write speeds.

Key Specifications

• Interface: PCIe Gen 3.0 x4, NVMe 1.3
• Sequential Read/Write: Up to 3400 MB/s / 3000 MB/s
• Controller: Variable (Phison PS5012-E12 / E12S, SM2262EN, or Realtek RTS5762)
• NAND Type: 3D TLC (Triple-Level Cell)
• DRAM Cache: Yes (Configuration varies by controller revision)
• Endurance Rating: Rated for high endurance (approx. 3115 TBW for the 2TB E12 variant)
• Form Factor: Double-sided M.2 2280 (PCB component density requires clearance on both sides)

Hardware Alternatives

• Corsair Force MP510: Shares the Phison E12 architecture but often features distinct firmware tuning for endurance.
• Sabrent Rocket (Gen3): The original version of this drive was physically identical to the early P34A80.
• PNY CS3030: Another direct hardware clone, though recent revisions of this model also saw reductions in TBW ratings.
• Samsung 970 EVO Plus 2000GB: The primary competitor in the Gen3 space, utilizing Samsung's Phoenix controller and V-NAND.
• WD Black SN750: Competes directly in throughput and latency using Western Digital's proprietary architecture and BiCS NAND.
