The SanDisk Optimus GX PRO 8100 is a 1TB M.2 2280 PCIe 5.0 x4 NVMe SSD for compatible PCs, with TLC NAND, up to 14,900 MB/s sequential reads and 11,000 MB/s writes, and a 5-year limited warranty. It suits gamers, creators, and professionals who need fast internal storage for demanding workloads.
Recommended For
- PC creators who regularly move large video, image, or project files and have a PCIe 5.0 M.2 slot; the drive’s high transfer speeds are most relevant when storage is part of a frequent, file-heavy workflow.
- Workstation users who frequently load large AI models or datasets and want fast local storage for those files; this SSD supports the data-loading side of an AI workflow, not the model’s computation.
- PC enthusiasts building around a PCIe 5.0 platform who want a fast system or project drive and can use a motherboard M.2 heatsink or provide suitable cooling; reviewers found strong performance across demanding storage tests.
- Gamers who prioritize a high-end SSD for a compatible PC and also use it for large installs or other demanding storage tasks; reviewers found the drive fast, though the difference in ordinary game loading may be modest.
Real-World Use Scenarios
- When launching large PC games or a heavily modded game from this drive, short reads and low access latency can make loading and asset access feel responsive; the difference may be smaller if you are upgrading from a good PCIe 4.0 SSD.
- When moving large video or project files between fast drives, this SSD can shorten transfer and copy waits; the result depends on the source drive, connection, file mix, and whether the system can keep the SSD cool.
- For a creator editing high-resolution footage or working with large project assets, using the drive for active files and scratch work can reduce storage-related waiting; its 1TB capacity may require offloading completed projects to separate storage.
- For local AI work, keeping frequently used models, datasets, or project files on the SSD can make loading and file access faster; the benefit depends on the workload, and 1TB limits how much can stay installed at once.
- In a compatible PCIe 5.0 desktop, using the drive as a fast system and application disk can help keep booting, app launches, and file access snappy; a PCIe 5.0-capable slot and adequate cooling are needed to make the most of it.

Reference Q&A
Q: SanDisk Optimus GX PRO 8100 1TB vs Samsung 9100 PRO 1TB: which should I buy?
A: Both are PCIe 5.0 x4 M.2 SSDs with a 600TBW rating. The SanDisk is rated for up to 14,900 MB/s reads and 11,000 MB/s writes; Samsung lists 14,800 MB/s reads and 13,400 MB/s writes. Choose the SanDisk if its price is lower or its rated read speed better fits your workload; choose the Samsung if its higher rated sequential write speed matters more. These are manufacturer ratings, not a direct real-world benchmark comparison.
Q: Is the GX PRO 8100 worth choosing over a PCIe 4.0 SSD like the WD Black SN850X for gaming?
A: For a gaming-focused build, choose the SN850X if it costs less and you do not have a specific workload that benefits from PCIe 5.0 transfer speeds. Choose the GX PRO 8100 for compatible PCIe 5.0 systems and demanding large-file transfers or creator workloads. The GX PRO 8100 has much higher rated sequential bandwidth, but that specification alone does not establish faster game loading.
Q: Should I get the GX PRO 8100 1TB or 2TB?
A: Choose 2TB if you need more room for games, project files, or other large data: it doubles capacity and is rated for up to 14,000 MB/s sequential writes, compared with 11,000 MB/s for the 1TB model. The 1TB model is the more suitable fit when capacity needs are modest or you want to spend less. Both have a five-year limited warranty; the 1TB is rated for 600TBW and the 2TB for 1,200TBW.
Q: Will this 2280 SSD fit a handheld or laptop that uses an M.2 2230 drive?
A: Not if the device requires an M.2 2230 module: this GX PRO 8100 is an M.2 2280 drive, which is longer. Check the device’s supported drive size before buying. For a compatible 2230 slot, consider a 2230 SSD such as SanDisk’s Optimus GX 7100M instead.
Q: Will this SSD fit my laptop or desktop?
A: It is an M.2 2280 NVMe SSD, so the computer needs a compatible M.2 PCIe slot with 2280-length clearance. Check your device’s specifications before buying; laptop fit can depend on slot support and available space.
Q: Does this SSD need a heatsink?
A: This 1TB model is listed without a heatsink. Check your motherboard or computer’s installation guidance for cooling requirements; if it provides a compatible M.2 heatsink, confirm it can be used with this bare drive.
Q: Will it reach its advertised speeds in my computer?
A: The advertised speeds require a compatible PCIe 5.0 x4 NVMe system. A computer with a different M.2 interface or PCIe generation may limit the drive’s performance, so check the motherboard or device specifications before buying.
Q: Is this SSD suitable for gaming and large creative projects?
A: It can suit a compatible PC used for games or demanding file work: it has 1TB of capacity, PCIe 5.0 x4 NVMe, and listed sequential read/write speeds of up to 14,900/11,000 MB/s. Actual performance depends on the host system and workload.
Q: Is the SanDisk Optimus GX PRO 8100 essentially the WD_BLACK SN8100 under a new name?
A: A Reddit post describes the GX PRO 8100 as a renamed SN8100 variant, and another lists both as options. For this 1TB model, check the exact listing’s specifications before buying: it is an M.2 2280 PCIe 5.0 x4 drive rated for up to 14,900 MB/s reads and 11,000 MB/s writes, and it has no heatsink. The discussion alone does not verify that every capacity or SKU has identical hardware or warranty terms.
