Manufacturer Contact Info

The SanDisk Optimus 5100 is a 4TB M.2 2280 NVMe SSD for PCIe 4.0 x4 systems, with sequential speeds up to 6,900 MB/s read and 6,700 MB/s write; it suits creators and power users who need fast access to large project files and substantial internal storage.

Recommended For

Creators upgrading a compatible laptop who need one internal drive for applications and large 4K video or high-resolution photo libraries; the 4TB capacity and single-sided M.2 2280 design suit that storage role.
Desktop PC users adding a high-capacity secondary drive for a growing media library, games, and project files, rather than relying on it for constant, very large write jobs.
PC gamers expanding an M.2 game library who want quick game launches and loads; a professional test of the related SN5100 drive found strong game-loading results, though the tested capacity was 2TB.
Mobile creators upgrading a compatible laptop who value a slim internal drive and lower-power design for carrying project files and working away from a desk.
