TEAMGROUP MP44Q 2000GB

The TEAMGROUP MP44Q 2000GB uses the Phison PS5027-E27T controller, a four-channel, DRAM-less design on a 12nm process, paired with high-density 3D QLC NAND. The drive employs Host Memory Buffer (HMB) to use a portion of system RAM for mapping tables and relies on a dynamic pseudo-SLC (pSLC) cache for sustained performance. It delivers peak burst speeds that saturate PCIe 4.0 but will fall back to native QLC write speeds once the pSLC cache is exhausted during large continuous transfers. The 2TB model is commonly a single-sided M.2 2280 design with a graphene-coated aluminum thermal label for passive cooling and has lower endurance ratings relative to TLC-based variants.

Key Specifications

• Interface: PCIe 4.0 x4 (NVMe 1.4)
• Controller: Phison PS5027-E27T (4-channel, DRAM-less)
• NAND Flash: 3D QLC (Quad-Level Cell)
• Host Memory Buffer: allows the controller to use system RAM for logical-to-physical mapping tables
• Sequential Read/Write: 7,000 MB/s / 5,900 MB/s
• Form Factor: M.2 2280 (single-sided PCB design common for 2TB)
• Endurance: lower TBW rating relative to TLC counterparts due to QLC bit density
• Thermal Management: graphene-coated aluminum thermal label (passive cooling)

Hardware Alternatives

• Corsair MP600 ELITE 2000GB: Shares the Phison E27T architecture but is typically paired with TLC NAND, offering higher endurance and more sustained write performance.
• Crucial P3 Plus 2000GB: A high-capacity QLC competitor that uses the older Phison E21T controller, resulting in lower peak throughput compared to E27T-based designs.
• TEAMGROUP MP44 (Non-Q): The brand sibling that typically uses the Maxio MAP1602 controller with TLC NAND, better suited for write-heavy workloads.
