Lighting-quick PCIe 5.0 Sandisk Optimus 1TB SSD drops to its lowest price in six months in Prime Day deal
Table of Contents
As the global SSD shortage continues, getting deals like this on premium storage are few and far between – so take full advantage of this Prime Day sale! The 1TB Sandisk Optimus GX PRO 8100 is a flagship PCIe 5.0 SSD capable of reaching up to 14,900MB/s sequential read speeds and 11,000MB/s sequential write speeds: these figures make it particularly attractive for large-file transfers, high-resolution content creation, software development and storage-heavy AI workloads. Gaming performance will also be excellent, although most games will not fully exploit the drive’s headline sequential speeds. Grab it now for 23% off recent peak prices – the lowest it’s been in at least 6 months on Amazon!
SANDISK 1TB Optimus GX PRO 8100
This specific SSD listing is for the 1TB model without an integrated heatsink, identified by model number SDSP82100TAN. To reach its maximum performance, the drive must be installed in an M.2 slot providing four PCIe 5.0 lanes: it is backward-compatible with earlier PCIe generations, but a PCIe 4.0 connection will substantially limit its sequential throughput. Real-world results will also depend on the processor, motherboard, available PCIe lanes, cooling, firmware, workload and amount of free capacity. Read below for more details on the specifications, or see the foot of this page for alternative SSD offers.
What we like about the Sandisk Optimus GX PRO 8100 1TB PCIe 5.0 NVMe SSD
Near-interface-limit PCIe 5.0 performance
The GX PRO 8100’s most notable feature is its rated sequential read speed of up to 14,900MB/s. That approaches the practical limits of a four-lane PCIe 5.0 connection and is more than twice the maximum sequential performance commonly associated with high-end PCIe 4.0 drives.

Its 1TB configuration is rated for sequential writes of up to 11,000MB/s. Although that is below the 14,000MB/s claimed for certain 2TB and 4TB models, it remains extremely fast for an internal consumer SSD. This level of throughput can substantially reduce the time required to move large video projects, virtual-machine images, game-development builds and other substantial files. These are peak sequential figures produced under suitable test conditions. Routine application launches, operating-system responsiveness and game loading depend more heavily on latency and random performance, so the difference from a good PCIe 4.0 drive will be less dramatic in everyday use.
Strong random performance
Sandisk rates the 1TB model for up to 1.6 million random-read IOPS and 2.4 million random-write IOPS. Random access is relevant when the system is processing large numbers of smaller files, running multiple applications or handling complex project directories. The random-write specification is especially strong and should suit demanding scratch-disk, compilation and creation workloads. Sandisk’s nCache 4.0 technology provides high-speed caching to accelerate burst writes and large transfers.
Compact M.2 2280 design
The drive uses the standard M.2 2280 form factor, measuring approximately 80mm by 22mm. It installs directly into a compatible motherboard or laptop slot without separate data and power cables. As mentioned, the SDSP82100TAN version is the model without Sandisk’s factory heatsink. This can be useful when a motherboard already includes an M.2 heat spreader or when space is restricted, but it places responsibility for adequate cooling on the system builder.
Improved power efficiency
Sandisk claims more than twice the power efficiency of its previous-generation PCIe 4.0 performance SSD, with average operating power specified at 7.5W or less across applicable capacities. Improved efficiency can reduce the amount of heat generated for a given level of performance. Nevertheless, this remains a high-performance PCIe 5.0 SSD. A substantial motherboard heatsink with a correctly installed thermal pad is strongly recommended if the drive will regularly handle sustained transfers. Insufficient cooling may cause thermal throttling, reducing performance until the drive’s temperature falls.
Laptop buyers should confirm both PCIe 5.0 support and available cooling before installation. Many notebooks accept bare M.2 drives but lack the thermal capacity required to sustain desktop-class Gen5 speeds.
Suitable for advanced workstations
The exceptional sequential bandwidth makes this drive most compelling for systems that regularly manipulate large datasets. Video editors, 3D artists, developers, engineering professionals and users experimenting with local AI workloads are more likely to benefit from it than someone whose workload consists primarily of browsing and office applications. It can also serve as a premium gaming drive, offering fast installation, patching and asset-streaming performance. However, frame rates are determined primarily by the processor and graphics card, while many game-loading workloads show only modest differences between capable PCIe 4.0 and PCIe 5.0 SSDs.
Modern BiCS TLC NAND
The GX PRO 8100 uses Sandisk’s eighth-generation BiCS TLC 3D CBA NAND. TLC flash generally offers a stronger combination of sustained performance, endurance and reliability than lower-cost QLC storage, making it appropriate for a performance-focused system drive.
Sandisk rates this 1TB version for 600 terabytes written. That is a substantial endurance allowance for a consumer PC and should comfortably cover years of gaming, general productivity and typical creative work.
Five-year limited warranty
The five-year limited warranty is appropriate for a premium internal SSD and provides useful long-term coverage. Its 600TBW endurance rating equates to writing roughly one-third of the drive’s capacity every day for five years, which is well beyond the usage of most gaming and general-purpose PCs. Warranty coverage should still be checked against the seller, region and full Sandisk terms. Buyers should also keep proof of purchase and confirm that the listing is supplied by Amazon or another authorized seller.
Backward compatibility adds flexibility
The GX PRO 8100 can operate through compatible PCIe 4.0 platforms, which makes it possible to carry the drive forward into a later Gen5 system. Buyers should understand that backward compatibility does not preserve its advertised 14,900MB/s performance; the connection will operate within the limits of the older interface. Console compatibility also requires care. A PlayStation 5 provides a PCIe 4.0 M.2 expansion slot and requires a correctly sized cooling solution, so this drive would receive no Gen5 speed advantage there. Xbox Series consoles do not accept a conventional M.2 NVMe drive as internal expansion storage for native Series X|S games.
Who should buy this 1TB SSD deal?
The Sandisk Optimus GX PRO 8100 1TB is best suited to enthusiasts and professionals building a modern desktop with a PCIe 5.0-capable M.2 slot. It is particularly relevant for users who transfer very large files, edit high-resolution media, compile substantial projects or need an exceptionally fast scratch drive. It also works for a no-compromise gaming PC, provided the motherboard offers suitable cooling. Gamers choosing strictly on value may receive a more meaningful benefit from a larger 2TB PCIe 4.0 SSD, since contemporary game libraries can consume 1TB quickly and loading-time improvements from Gen5 storage vary by title.
Before buying, confirm that the motherboard supports PCIe 5.0 x4 storage and has an effective M.2 heatsink. Also note that a nominal 1TB drive provides less usable space after formatting and system overhead.
