Silicon Power P34A60 2000GB

SSD Description

The Silicon Power P34A60 2000GB is an entry-level NVMe solution with a DRAM-less architecture, typically using the Silicon Motion SM2263XT controller paired with 3D TLC NAND. To compensate for the lack of on-board DRAM it relies on Host Memory Buffer (HMB) to access a portion of system RAM for mapping tables. The drive uses a PCIe 3.0 x4 interface but throughput is effectively limited by the 4-channel controller design. Production batches have shown variable bill of materials, with occasional component swaps (Phison E13T controller or different NAND suppliers such as Micron or YMTC) without SKU changes. The 2000GB model is commonly single-sided (2280), improving compatibility with ultra-thin notebooks. During large sustained writes, the dynamic SLC pseudo-cache can saturate, after which write speeds drop significantly.

Key Specifications

• Interface: PCIe 3.0 x4 / NVMe 1.3
• Controller: Silicon Motion SM2263XT (Common) or Phison E13T (Variant)
• NAND Flash: 3D TLC
• Sequential Read: Up to 2,200 MB/s
• Sequential Write: Up to 1,600 MB/s
• DRAM Cache: None (HMB Support)
• Physical Trait: Single-sided PCB (2280 Form Factor)

Hardware Alternatives

• TeamGroup MP33 / Patriot P300: These drives are direct hardware relatives, frequently utilizing the same SM2263XT reference design and HMB architecture, offering nearly identical performance profiles and thermal characteristics.
• Crucial P2 / Kingston NV1: These models operate in the same entry-level segment; the P2 and NV1 have historically migrated to QLC NAND in later revisions, which can reduce endurance and sustained write performance compared with drives that remain on TLC.
• WD Blue SN570 / Samsung 980 2000GB: These are primary proprietary competitors that, while also using DRAM-less architectures, use in-house controller and NAND integration that typically yield higher sustained throughput and random I/O performance than merchant-silicon-based designs.
