TeamGroup MP44 - M.2 PCIe Gen4 NVMe SSD - 4TB

The TeamGroup MP44 is a high-performance DRAMless Gen4 NVMe drive that competes directly with the Samsung 990 EVO Plus and WD Black SN770. It uses a Maxio MAP1602 controller with TLC NAND and Host Memory Buffer. Sequential speeds reach 7,000/6,000 MB/s read/write on capacities from 1TB to 8TB, with the 512GB model dropping to 6,700/4,400 MB/s. The standout feature is the 8TB capacity option, which is rare in the M.2 2280 form factor.

DRAMless but Fast

At the 7,000 MB/s read speed tier, the MP44 pushes near the Gen4 x4 bandwidth ceiling without the cost of onboard DRAM. For consumer workloads (gaming, boot drive, general-purpose storage), HMB keeps latency low enough that most users won't notice the absence of DRAM. Sustained random I/O under heavy queue depth is where DRAM-equipped drives like the Samsung 990 Pro or TeamGroup's own Cardea A440 pull ahead.

8TB Capacity

The MP44 goes up to 8TB in a standard M.2 2280 form factor. That amount of high-speed NVMe storage in a single slot is unusual. For builds where physical drive slots are limited (small form factor PCs, laptops), the 8TB MP44 eliminates the need for multiple drives.

Endurance

250 TBW (512GB), 500 TBW (1TB), 1,000 TBW (2TB), 2,000 TBW (4TB), 4,000 TBW (8TB). Five-year limited warranty.

Best for: Budget-conscious Gen4 builds that want near-maximum sequential speeds. The 8TB model is compelling for SFF builds or anyone consolidating multiple drives. Game libraries and media storage where capacity matters more than sustained random I/O.

Avoid if: You need sustained random write performance under heavy mixed workloads. A DRAM-equipped drive (Cardea A440, Samsung 990 Pro) handles that better. The 512GB model has noticeably slower writes (4,400 MB/s).
