As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The lexar 4tb nm790 internal nvme SSD alternatives list helps you find drives that match its high-end specs. This drive offers 7400 MB/s reads and 3000 TBW endurance using PCIe Gen 4x4. It uses Host Memory Buffer 3.0 instead of a dedicated DRAM cache. This design keeps power consumption low while delivering fast transfer speeds for gaming and content creation. You might look elsewhere if you need a different form factor or a specific thermal solution. Some builds require a thinner profile or a dedicated heatsink. Others may prioritize a different NAND type or a longer warranty period. You might also prefer a smaller capacity like 2TB for budget-conscious upgrades. We selected these options because their published specifications overlap significantly with the NM790. Each alternative shares the M.2 2280 form factor and PCIe 4.0 interface. They all target similar use cases, such as PS5 expansion or desktop storage. The following 6 drives provide distinct advantages in speed, thickness, or endurance. You can compare their exact ratings to find the best fit for your system.
Our top pick: Lexar NM790 4TB NVMe M.2 SSD.
Key Differences in Specs and Features
The Acer Predator GM7000 uses dedicated DRAM cache instead of the Lexar NM790’s Host Memory Buffer. This hardware cache can handle more demanding random write workloads with greater consistency. Both drives offer identical 7400 MB/s read speeds and 4TB capacity. However, the Acer has a lower endurance rating of 1300 TBW compared to the Lexar’s 3000 TBW. The Acer also includes a bundled heat spreader, whereas the Lexar relies on system airflow. If you prioritize sustained heavy writes and included cooling, the Acer is a strong choice. For higher endurance and lower power usage, the Lexar remains the better option.
The Transcend Graphene NVMe SSD features an integrated graphene thermal layer for active heat dissipation. This hardware cooling solution differs from the Lexar NM790, which relies on HMB and passive cooling. Transcend offers slightly faster sequential reads up to 7500 MB/s. Both drives are PCIe 4.0 M.2 2280 models with 4TB capacity. The Transcend includes a heatsink, adding bulk but improving thermal stability. The Lexar is thinner and more power-efficient. You should choose the Transcend if your system lacks airflow and needs built-in cooling. The Lexar is better for compact builds where height and power consumption are critical constraints.
The Mushkin Vortex 4TB Gen4 NVMe SSD provides 7415 MB/s read speeds, nearly matching the Lexar NM790. It uses the InnoGrit IG5236 controller for high-capacity performance. Unlike the Lexar’s HMB approach, the Mushkin focuses on raw sequential throughput for PS5 and PC expansion. Both are M.2 2280 drives with 4TB capacity. The Mushkin is compatible with PS5, similar to the Lexar. However, the Mushkin does not specify an endurance rating in the provided data. The Lexar offers 3000 TBW. If you need a PS5-compatible drive with comparable speeds and a known warranty, the Mushkin is a solid alternative. The Lexar offers better documented endurance for long-term data safety.
The Corsair MP600 CORE XT 4TB Gen4 NVMe SSD uses QLC NAND, unlike the Lexar NM790’s likely TLC configuration. This affects endurance and sustained write speeds. Corsair offers 5000 MB/s reads, which is slower than the Lexar’s 7400 MB/s. Both are M.2 2280 drives with 4TB capacity. The Corsair is designed for everyday storage where capacity matters more than peak speed. It fits desktops and laptops. The Lexar provides higher speeds and better endurance for demanding tasks. You should pick the Corsair if you prioritize lower cost per terabyte for general storage. Choose the Lexar if you need faster transfers for gaming or content creation.
TEAMGROUP MP44 4TB PCIe 4.0 SSD
The TEAMGROUP MP44 4TB PCIe 4.0 SSD features a graphene label for heat dissipation and uses SLC caching. This differs from the Lexar NM790’s HMB 3.0 configuration. Both drives offer 4TB capacity in the M.2 2280 form factor. The TEAMGROUP is tailored for laptops due to its slim profile and thermal management. The Lexar is more power-efficient and offers higher sequential speeds. The TEAMGROUP provides SLC caching for better burst performance. If you are upgrading a laptop and need effective cooling without a bulky heatsink, the TEAMGROUP is suitable. The Lexar is better for desktops or systems where maximum speed and endurance are the primary concerns.
Fanxiang 4TB PCIe 4.0 NVMe SSD
The Fanxiang S880 4TB PCIe 4.0 SSD uses TLC NAND and SLC caching, similar to high-performance drives. It offers 7300 MB/s reads, slightly below the Lexar NM790’s 7400 MB/s. Both are M.2 2280 drives with 4TB capacity. The Fanxiang is optimized for gaming and PS5 expansion. It lacks a DRAM cache, relying on SLC caching like the Lexar’s HMB. The Fanxiang is thinner, which may help in tight spaces. If you want a gaming-focused drive with TLC NAND and comparable speeds, the Fanxiang is a viable option. The Lexar offers slightly higher speeds and better power efficiency. Choose the Fanxiang if you prioritize gaming compatibility and TLC NAND at a potentially lower price point.
