How these drives compare to the SN850X
Sandisk WD_Black SN7100 4TB NVMe SSD
The Sandisk WD_BLACK SN7100 4TB NVMe SSD targets laptop users who need efficient 4TB Gen4 storage. While the SN850X prioritizes raw speed with 7,300 MB/s reads, the SN7100 focuses on thermal efficiency and endurance, offering 2,400 TBW. It shares the M.2 2280 form factor but may run cooler in confined laptop chassis. If you prioritize battery life and sustained writes over peak burst speeds, this drive is a strong candidate. It lacks the extreme read throughput of the SN850X but provides reliable performance for mobile workstations.
WD_BLACK SN850 2TB Gen4 NVMe SSD
The WD_BLACK SN850 2TB Gen4 NVMe SSD offers up to 7,000 MB/s read speeds, slightly lower than the SN850X’s 7,300 MB/s. It delivers 1,000,000 IOPS, making it effective for gaming systems that do not require 4TB capacity. The 2TB size reduces cost and weight while maintaining high-speed PCIe Gen4 performance. If you need less storage but similar gaming load times, this is a viable alternative. It shares the M.2 2280 form factor and black color scheme, fitting easily into most gaming PCs without requiring different mounting hardware.
Western Digital WD Red SN700 4TB NAS NVMe SSD
The Western Digital WD Red SN700 4TB NAS NVMe SSD is built for multi-user NAS devices and virtualization rather than gaming. It provides 4TB of PCIe Gen3 storage with read speeds up to 3,400 MB/s, significantly slower than the SN850X’s Gen4 speeds. This drive is tested for popular NAS systems, making it ideal for home servers or virtualization hosts. If you need high endurance and consistent performance for multiple users, this NAS-focused drive is better suited than the gaming-oriented SN850X, despite the lower transfer rates.
INLAND Gaming 4TB PCIe Gen4 NVMe SSD
The WD_BLACK SN770 2TB Gen4 NVMe SSD provides balanced performance up to 5,150 MB/s, which is lower than the SN850X’s 7,300 MB/s. It is DirectStorage ready and offers reliable direct-to-motherboard storage for setups that do not need 4TB capacity. The 2TB size is suitable for users who prioritize speed over sheer volume. It shares the M.2 2280 form factor and gaming compatibility. If you want fast Gen4 performance without the premium price or heat of the SN850X, this balanced drive is a practical choice for gaming PCs.
INLAND Gaming 4TB PCIe Gen4 NVMe SSD
The INLAND Gaming 4TB PCIe Gen4 NVMe SSD delivers fast Gen4 read speeds up to 7,100 MB/s, close to the SN850X’s 7,300 MB/s. It offers strong 3,000 TBW endurance and includes a heatsink for thermal management, which the SN850X does not always include by default. This drive serves as a dependable high-capacity alternative for demanding PC and console builds, including PS5. If you need high endurance and built-in cooling for sustained gaming sessions, this INLAND option provides similar speed with added thermal protection in a slightly larger form factor.
Sandisk WD_BLACK SN850X 1TB NVMe SSD
