The SanDisk Optimus GX 7100 is a 4TB M.2 2280 PCIe 4.0 x4 NVMe SSD with read speeds up to 7,000 MB/s and write speeds up to 6,700 MB/s, suited to PC gamers who want fast game storage and room for a large library.
Recommended For
- PC gamers with an M.2 2280 slot who want room for a large installed game library, updates, and downloadable content on one drive.
- Gamers and everyday PC users who want a responsive PCIe 4.0 drive for game loading, application use, and mixed desktop workloads; testing of the 2TB model found strong results in random reads and application-oriented benchmarks.
- Laptop or compact-PC owners upgrading a compatible M.2 2280 slot who want a high-capacity internal drive for games and creative projects; SanDisk positions the GX 7100 for laptop and on-the-go workflows.
- Creators who want a fast 4TB working drive for active projects and typical file transfers, rather than a drive dedicated to uninterrupted, very large write jobs.
Real-World Use Scenarios
- A PC gamer keeps a large collection of AAA games, updates, and downloadable content installed at once; the 4TB capacity helps reduce the need to uninstall games to make room for new ones.
- A gamer installs the drive in a compatible PC as the game drive; games and applications can load from fast NVMe storage, though the drive alone does not increase game frame rates.
- A desktop user upgrades a compatible M.2 2280 system drive and migrates Windows and existing files; SanDisk lists Acronis True Image for drive migration, while actual startup and app-loading gains depend on the previous drive and the rest of the PC.
- A video or photo creator keeps active projects and frequently used media on the internal drive; the capacity provides room for sizable working files, while very large continuous write jobs may slow after the drive’s write cache is used.
- A laptop owner adds internal storage for games or creative files; this use fits only if the laptop has an available M.2 2280 slot and supports a PCIe NVMe drive, so users should check the device’s compatibility and cooling requirements first.

Reference Q&A
Q: SanDisk Optimus GX 7100 4TB or Samsung 990 PRO 4TB?
A: Both are 4TB PCIe 4.0 x4 M.2 2280 TLC drives, but the 990 PRO has higher rated peak speeds: 7,450/6,900 MB/s sequential read/write versus 7,000/6,700 MB/s for the GX 7100 4TB. Samsung also specifies onboard DRAM; the GX 7100 uses Host Memory Buffer. Choose the 990 PRO if its higher rated performance and dedicated DRAM are priorities. Choose the GX 7100 if its pricing or SanDisk-specific features better suit your build. An independent review tested the GX 7100 in 2TB form, so its benchmark results should not be treated as a direct 4TB comparison.
Q: Is the GX 7100 4TB worth choosing over the 2TB version?
A: Choose the 4TB version when you need more room for games and files: it doubles capacity and is rated for 2,400 TBW, compared with 1,200 TBW for the 2TB model. The 2TB model has higher rated peak performance—up to 7,250/6,900 MB/s sequential read/write and 1.0M/1.4M random read/write IOPS, versus 7,000/6,700 MB/s and 900K/1.35M IOPS for the 4TB model. In short, the 4TB version favors capacity and rated endurance; the 2TB version favors peak specifications.
Q: Should I get the GX 7100 4TB or WD_BLACK SN850X 4TB?
A: Both are 4TB PCIe Gen4 M.2 2280 TLC SSDs, and both are offered without a heatsink. The SN850X has higher rated sequential read speed (7,300 versus 7,000 MB/s), while the GX 7100 has a higher rated sequential write speed (6,700 versus 6,600 MB/s) and random write rating (1.35M versus 1.1M IOPS). Choose based on the workload and specification that matters more; these manufacturer ratings are not a direct real-world 4TB benchmark comparison.
Q: Will this SSD work in my laptop or desktop?
A: It can work in a system with an available M.2 2280 slot that supports PCIe NVMe SSDs. Check the computer’s manual for supported drive type, capacity, and physical clearance before buying; the product specifications alone cannot confirm compatibility with a specific system.
Q: Does this SSD include a heatsink?
A: No. This model is listed without a heatsink. Check the computer or device’s cooling and clearance requirements; if a heatsink is needed, use one that fits the device and the 80 × 22 mm drive.
Q: Will it reach its advertised speed in my computer?
A: The drive is rated for sequential reads up to 7,000 MB/s and writes up to 6,700 MB/s. Actual speeds depend on the system’s M.2 slot, PCIe generation, workload, and other system limits; a slower or different interface may reduce performance.
Q: Who is a 4TB SSD like this suitable for?
A: Its 4TB capacity and PCIe 4.0 x4 interface suit users who need substantial internal storage for games, media, or large work files and have a compatible M.2 2280 NVMe slot. It may be more capacity than needed for lighter storage use.
Q: Is the Optimus GX 7100 a suitable storage upgrade for a Steam Machine?
A: It may be suitable if the Steam Machine supports an M.2 2280 PCIe 4.0 x4 NVMe drive and 4TB capacity. Check the device’s specifications before buying; the product listing does not confirm compatibility with a specific system.
Q: Do the GX 7100’s high read and write speeds make a noticeable difference for gaming?
A: The drive is rated for sequential speeds up to 7,000 MB/s read and 6,700 MB/s write. A Reddit discussion about the GX 7100 says its maximum speeds are unlikely to make a significant difference during gameplay, so capacity and compatibility may matter more for a game-storage upgrade.
Q: Does the GX 7100 need a heatsink in a handheld gaming device?
A: This 4TB model is listed without a heatsink. Whether it needs a thermal pad or heatsink depends on the handheld’s space and cooling design; check the device’s installation guidance and clearance before adding one.
Q: Is a 4TB GX 7100 worth buying for a handheld upgrade?
A: It can make sense if you need 4TB in a compatible M.2 2280 slot. The product data gives its capacity and interface but not its price, so whether it is worth buying depends on the current cost and how much storage you need.
