SSD M.2 Lexar 4TB PCIe Gen 4X4 NM790 NVMe


Lexar 4TB NM790 SSD Review

The Lexar 4TB NM790 SSD is a high-performance M.2 NVMe drive designed for gamers, professionals, and content creators. It leverages the latest PCIe Gen 4x4 interface, offering exceptional read and write speeds that make it a compelling choice for those seeking both capacity and speed.

Performance

The Lexar NM790 boasts sequential read speeds of up to 7,400 MB/s and write speeds of up to 6,500 MB/s, making it one of the fastest SSDs in its class. These speeds are achieved through the use of advanced Dynamic SLC caching and Host Memory Buffer (HMB) 3.0 technology, which allows the SSD to utilize system RAM instead of relying on its own memory, contributing to its high efficiency and lower power consumption.

Capacity and Compatibility

With a capacity of 4TB, the NM790 is ideal for storing large gaming libraries, video editing files, and other high-capacity data. It is compatible with desktop computers, laptops, and the PlayStation 5, making it a versatile option for various use cases.

Efficiency and Reliability

The SSD is designed to be energy-efficient, consuming up to 40% less power than competing Gen 4 SSDs with DRAM caches. It also boasts a mean time between failures (MTBF) of 1.5 million hours and an endurance rating of 6,000 TBW, ensuring long-term reliability and durability.

Pros

  • High Performance: The NM790 delivers exceptional read and write speeds, making it suitable for demanding applications.
  • Efficient: It consumes less power compared to other Gen 4 SSDs, reducing heat generation and extending battery life.
  • Reliable: With a high MTBF and TBW rating, it ensures long-term reliability.
  • Versatile: Compatible with a wide range of devices, including desktops, laptops, and the PlayStation 5.
  • Affordable: Despite its high performance, it is generally priced competitively, making it a great value for money.

Cons

  • 4K Random Access: While the NM790 excels in sequential performance, its 4K random access results are not stellar, which might be noticeable in specific workloads.
  • Controller and NAND: The use of a lesser-known controller and flash memory combo might raise concerns about long-term support and updates.

Verdict

The Lexar 4TB NM790 SSD is an excellent choice for anyone seeking a high-capacity, high-performance SSD. Its exceptional read and write speeds, combined with its efficiency and reliability, make it a solid investment for both gamers and professionals. While it may not excel in 4K random access, its strengths in sequential performance and overall efficiency make it a compelling option.
