Affordable SSD Drive Utilizing RAM as a Buffer

The Lexar NM790 is a high-speed solid-state drive in M.2 2280 format with a PCIe Gen 4x4 NVMe interface, offering read speeds up to 7400 MB/s and write speeds up to 6500 MB/s. Thanks to Host Memory Buffer (HMB) 3.0 technology, it uses the computer's RAM for accelerated data access, allowing it to perform nearly at the level of SSDs with DRAM cache, while remaining more affordable and energy-efficient.

One of the Fastest HMB SSDs on the Market

HMB 3.0 minimizes latency and speeds up handling of small files, while dynamic SLC caching helps maintain high performance even under heavy loads. However, once the cache is filled (approximately 200 GB for the 1 TB model), the write speed drops to 1800 MB/s – insignificant for gaming, but noticeable when transferring large archives. Compared to popular HMB drives like the WD SN770 (5150/4900 MB/s), the Lexar NM790 stands out with higher read and write speeds (7400/6500 MB/s), increased IOPS (900–1000 thousand), and higher endurance (up to 1000 TB). These features make it an excellent choice for video editing and other professional tasks involving large file processing.

Energy Efficiency for Ultrabook Owners

One of the advantages of the Lexar NM790 is its 40% reduced power consumption compared to counterparts with DRAM cache. For desktop PCs, this is less critical, but for ultrabooks, where every watt counts, this becomes a significant plus. Moreover, the drive is fully compatible with PlayStation 5, as its speed exceeds Sony’s recommended threshold of 5500 MB/s. Combining an affordable price, durable 232-layer flash memory, and high performance, the Lexar NM790 is a versatile solution suitable for both gamers and professionals.
