GIGABYTE 4000E 500GB M.2 NVMe Gen4 Solid State Drive ( SSD )

The GIGABYTE 4000E 500GB M.2 NVMe Gen4 SSD (model G440E500G) is a PCIe 4.0 x4 internal solid state drive built for users who need fast, reliable storage in a compact M.2 2280 form factor. Operating under the NVMe 1.4 specification, it delivers sequential read speeds of up to 3,600 MB/s and sequential write speeds of up to 3,000 MB/s, making it a capable upgrade for gaming rigs, workstations, and content-creation setups that demand rapid data access and file transfers. One of the standout features of the 4000E is Host Memory Buffer (HMB) support. Rather than requiring dedicated DRAM on the drive itself, HMB leverages the system's existing memory via PCIe DMA, helping maintain consistent performance during sustained workloads without adding cost or power overhead. This makes the drive particularly attractive in budget-conscious builds where efficiency matters. Data integrity and long-term health are addressed through native TRIM, S.M.A.R.T., and Over-Provision support. TRIM keeps write performance stable over time by proactively managing unused blocks, while S.M.A.R.T. enables real-time health monitoring so you can anticipate issues before they become failures. Over-provisioning reserves additional NAND capacity to extend drive lifespan. GIGABYTE bundles the SSD Tool Box software, which provides a clear dashboard of drive health, firmware version, sensor temperature, and a Secure Erase function for safe data removal. The drive is also supported by GIGABYTE CONTROL CENTER (GCC), a unified management platform covering all GIGABYTE hardware in a single interface.
