SanDisk SSD PLUS 2000GB

The SanDisk SSD PLUS 2000GB is an entry-level SATA DRAM-less drive for low-queue-depth client workloads. Western Digital uses a fluid Bill of Materials strategy for this model line; the 2TB variant typically pairs a proprietary SanDisk-branded controller (often a rebadged Silicon Motion SM2258XT or similar) with SanDisk BiCS 3D NAND. The drive relies on an SLC pseudo-caching strategy to mask native flash write speeds and lacks a dedicated DRAM buffer for the logical-to-physical mapping table. The SSD PLUS line exhibits significant component variation between batches, and sustained write performance can suffer once the SLC cache is saturated during large transfers, occasionally dropping to very low speeds. The drive uses a plastic composite casing that limits heat dissipation during prolonged activity and does not include hardware-based TCG Opal encryption support.

Key Specifications

• Interface: SATA III (6 Gb/s)
• Sequential Read/Write: 545 MB/s Read / 515 MB/s Write
• Controller: Variable (SanDisk Proprietary / Silicon Motion DRAM-less variants)
• NAND Type: Variable (typically SanDisk BiCS 3D TLC or QLC depending on revision)
• DRAM Cache: None (DRAM-less)
• Physical Trait: Plastic composite casing (Thermally insulated)
• Encryption: Lacks hardware-based TCG Opal encryption support

Hardware Alternatives

• Western Digital WD Green SATA SSD: This drive is the functional twin of the SanDisk SSD PLUS. They typically share identical internal architecture, firmware profiles, and performance behaviors, differentiated only by branding stickers and chassis coloration.
• Crucial BX500: A direct competitor in the DRAM-less SATA tier. Like the SSD PLUS, the BX500 frequently alternates between TLC and QLC NAND and suffers from similar thermal and sustained write limitations.
• Kingston A400: Occupies the same hardware segment, typically utilizing Phison S11 controllers. It offers a comparable performance profile for basic OS boot duties and secondary storage.
