The SanDisk Optimus GX PRO 850X is a 4 TB internal solid-state drive designed for high-performance computing tasks. It uses the PCIe 4.0 interface and an M.2 2280 form factor, making it suitable for modern gaming PCs, content creation workstations, and compatible laptops. This drive achieves sequential read speeds of up to 7,300 MB/s and sequential write speeds of up to 6,600 MB/s. These performance figures contribute to reduced loading times in applications and faster transfer of large files.
Built with BiCS TLC 3D NAND, this SSD balances high capacity with an endurance rating of 2400 terabytes written (TBW). The drive's random I/O performance reaches up to 1,200,000 IOPS for reads and 1,100,000 IOPS for writes, which enhances system responsiveness during multitasking. For data security, it includes hardware-based TCG Opal v2.01 encryption. In addition to personal computers, this model is also compatible with PS5 and PS5 Pro game consoles for storage expansion.
