Lexar NM790 4TB SSD with Heatsink Review
Overview The Lexar NM790 4TB SSD is a high-performance, budget-friendly M.2 NVMe drive designed for gamers, content creators, and anyone needing ample storage without compromising speed. It leverages a PCIe Gen 4x4 interface, offering sequential read speeds of up to 7,400 MB/s and write speeds of up to 6,500 MB/s.
Performance The NM790 delivers exceptional performance across various benchmarks. Its use of advanced Dynamic SLC caching and Host Memory Buffer (HMB) 3.0 technology allows it to utilize system RAM efficiently, contributing to its high performance and lower power consumption. This makes it an excellent choice for both desktop and laptop users.
Thermal Performance One of the standout features of the NM790 is its thermal performance. Despite not having a built-in fan, the drive runs cool and calm, even under heavy loads. This is particularly impressive given its high performance capabilities. However, it's worth noting that additional cooling might be required under extreme conditions.
Compatibility and Design The NM790 is designed to be compatible with a wide range of devices, including laptops, desktops, and the PlayStation 5. Its single-sided design makes it perfect for laptops, and its M.2 2280 form factor ensures easy installation in most modern systems.
Pros:
- High Performance: Offers sequential read speeds of up to 7,400 MB/s and write speeds of up to 6,500 MB/s.
- Efficient: Consumes up to 40% less power than competing Gen 4 SSDs with DRAM caches.
- Affordable: Available at competitive pricing, with 1 TB models retailing around $80 and 2 TB models around $130.
- Wide Compatibility: Compatible with PS5, laptops, and desktops.
- Reliable: Boasts a 5-year limited warranty and an endurance rating of 6,000 TBW.
Cons:
- Thermal Considerations: While it runs cool, additional cooling might be required under heavy loads.
- Controller and NAND: Uses a lesser-known controller and flash memory combo, which might raise concerns about long-term reliability.
Verdict The Lexar NM790 4TB SSD with heatsink is an excellent choice for those seeking high performance at an affordable price. Its efficient design, wide compatibility, and reliable performance make it a top pick for gamers and content creators. While it may require additional cooling under extreme conditions, its overall performance and value make it a solid investment.
