Description
PCIe Gen 5.0 Up to 14,900 MB/s 8TB Capacity
The fastest consumer NVMe SSD on the market — 8TB, PCIe Gen 5.0, up to 14,900 MB/s read, with an integrated RGB heatsink built for gaming rigs and professional workstations.
The WD_BLACK SN8100 NVMe SSD with Heatsink is the flagship storage solution for PC builders, gamers, and content creators who demand the absolute best. Built on PCIe Gen 5.0 x4 with advanced TLC 3D CBA NAND technology, it delivers sequential read speeds up to 14,900 MB/s and write speeds up to 13,200 MB/s — making it one of the fastest consumer SSDs ever benchmarked. At 8TB capacity, it is also the highest-capacity PCIe Gen 5.0 M.2 SSD available for consumer systems.
The integrated heatsink features anodized aluminum construction, double TIM pads, and customizable RGB lighting — designed to maintain peak performance in high-demand systems without requiring active cooling. Available at ITFactory.ca — Canada's trusted source for premium PC storage.

Why PCIe Gen 5.0 Matters — and Why the SN8100 Leads It PCIe Gen 5.0 doubles the bandwidth of Gen 4.0, enabling SSDs to operate at speeds that were previously only possible in enterprise storage. The WD_BLACK SN8100 is not only built on Gen 5.0 — it is currently the benchmark leader for sequential read performance among all consumer SSDs, edging out the Samsung 9100 Pro's 14,800 MB/s with its 14,900 MB/s read speed. Equally important: the SN8100 is over 100% more power efficient than the WD_BLACK SN850X (PCIe Gen 4.0). Faster speeds with lower power draw means less heat, more headroom for sustained workloads, and better compatibility with high-performance laptop and desktop builds. |

Frequently Asked Questions
Does my motherboard support PCIe Gen 5.0 M.2?
PCIe Gen 5.0 M.2 slots are available on motherboards with Intel Z790 (12th/13th/14th Gen), Intel Z890 (Core Ultra 200S), and AMD X670E/X870E (Ryzen 7000/9000 series) chipsets. Check your motherboard's specifications for an M.2 slot labelled PCIe 5.0. If your motherboard only has PCIe Gen 4.0 or Gen 3.0 M.2 slots, the SN8100 will still work but at the lower speeds of the available slot — backward compatibility is fully supported.
Do I need the heatsink version or can I use the one on my motherboard?
PCIe Gen 5.0 SSDs generate more heat than Gen 4.0 drives during sustained workloads — thermal throttling can reduce performance if the drive runs too hot. If your motherboard includes a high-quality M.2 heatsink that covers the 2280 slot, you can use the drive without the integrated heatsink (it is removable). If your motherboard's heatsink is minimal or absent, the integrated heatsink version is strongly recommended for maintaining sustained peak performance.
How does the SN8100 compare to the Samsung 990 Pro and 9100 Pro?
The Samsung 990 Pro is a PCIe Gen 4.0 drive — significantly slower in sequential throughput than Gen 5.0 drives. Against the Samsung 9100 Pro (Gen 5.0), the SN8100 leads slightly in sequential read speed (14,900 vs 14,800 MB/s) while the 9100 Pro has slightly faster write speeds in some configurations. The SN8100 is also notably more power efficient than competing Gen 5.0 drives. Both are excellent; the SN8100 currently holds the sequential read benchmark lead among consumer SSDs.
Is 8TB realistic for a single M.2 SSD?
Yes — the WD_BLACK SN8100 is one of the first consumer M.2 NVMe SSDs to reach 8TB capacity in the standard 2280 form factor. It uses high-density CBA NAND to achieve this without requiring a double-sided PCB, keeping it compatible with most M.2 slots. Note that 1TB = 1 trillion bytes in manufacturer specifications — actual formatted capacity available to the operating system will be slightly less, typically around 7.27TB as displayed by Windows.
Is this suitable for gaming — will I notice a difference over Gen 4.0?
For traditional game loading screens, the difference over a fast Gen 4.0 drive is marginal — most games are not bottlenecked by storage speed at those access patterns. Where the SN8100 delivers a noticeable advantage is in games using Microsoft DirectStorage, open-world titles that stream assets in real time, and in game installation and update speeds. If you are building a future-ready system or running a workstation that doubles as a gaming machine, the SN8100 is a justifiable upgrade. For pure gaming only, a fast Gen 4.0 drive remains excellent value.
