The Addlink S90 Lite NVMe PCIe Gen4x4 M.2 SSD is a cutting-edge storage solution engineered for those who demand speed and reliability. Utilizing the PCIe Gen 4 NVMe 1.4 interface, this drive is specifically designed for the latest Intel and AMD platforms, making it an ideal upgrade for gamers, content creators, and engineers who require rapid data access for intensive workloads. Performance is driven by a Phison E21T controller and 176-layer 3D TLC NAND flash. While it is a DRAM-less design, it employs Host Memory Buffer (HMB) technology, which utilizes a portion of the system's RAM to maximize random read/write performance and ensure lag-free multitasking. Combined with SLC caching, the S90 Lite achieves sequential read speeds of up to 5000MB/s and write speeds up to 4200MB/s, performing up to ten times faster than traditional SATA III SSDs. Built for longevity and data integrity, the S90 Lite incorporates LDPC ECC technology, advanced Wear Leveling, Bad Block Management, and Over-Provisioning. These features work together to ensure high data accuracy and extend the overall lifespan of the drive. Its energy-efficient design keeps active power consumption at just 3.9W, reducing heat output during operation. Physically, the S90 Lite features a simple, single-sided design. This makes it highly compatible with a wide range of devices, including slim laptops and compact desktop builds, as it is easier to cool and fits into most M.2 slots. Whether you are building a new high-performance PC or upgrading an existing laptop, the S90 Lite provides a balanced blend of mid-range performance and exceptional value, backed by a limited five-year warranty.
