No bottleneck
A PCIe 5.0 x4 slot has twice the bandwidth of a Gen 4 one. The SN8100 is built to fill it: that is why the read figures almost double the previous generation.

PCIe GEN 5
01 / SPEEDFourteen thousand nine hundred.Not a typo.
The SN8100 reaches up to 14,900 MB/s sequential read in an M.2 slot with PCIe 5.0 x4. Writes go up to 14,000 MB/s on the 2 and 4 TB models. These are the figures published by the official SanDisk sheet, measured in their lab.
14,900 MB/sMaximum sequential read
14,000 MB/sWrite on 2 and 4 TB
2.3 M IOPSRandom read (2 and 4 TB)
PCIe 5.0 x4NVMe 2.0 interface
TLC 3D CBA memory
The NAND is stacked on top of its own controller (CBA), with nCache 4.0. A shorter path for the data and less heat per written bit.
GAMING
02 / GAMINGThe map already loaded.While you read this.
Modern games stream textures while you play. With a Gen 5 drive the system stops waiting for the disk. We do not promise FPS: frames come from your processor and graphics card, and change with every game.
Your whole library
From 1 TB to 8 TB, so you never again choose what to uninstall this month.
Automatic game mode
SanDisk Dashboard (Windows) turns game mode on when it detects you open a game, and watches the health of the drive.
CREATION AND AI
03 / CREATION AND AIHeavy projects.No complaints.
High-resolution editing, audio layers, renders and AI models loaded from disk: all of them are large, sustained reads. That is where a Gen 5 drive shows, especially with the heatsink on.
Timeline without proxies
Fast and efficient: the official sheet states an average power of 7.5 W or under, over 100% more efficient than the brand PCIe Gen 4 generation.
Datasets and models
Up to 4,800 TBW of endurance on the 8 TB model, with 1.75 million hours MTTF and TCG Opal 2.02 encryption.
TEMPERATURE
04 / TEMPERATUREFast for a long time.Not just the first minute.
A Gen 5 SSD gets hot. If the temperature climbs too high it slows down to protect itself. That is why this model comes in two versions and the choice matters.
With heatsink
Anodised aluminium, low profile and configurable RGB light. According to SanDisk it holds performance up to 15 times longer than the bare version under heavy load. No fans, no extra cables.
Without heatsink
For boards that already have their own M.2 heatsink (most current high-end ones) or for builds where nothing else fits.
The simple rule
If your board has an M.2 heatsink, buy the bare version. If it does not, buy the heatsink one.
CAPACITIES
05 / CAPACITYFour sizes.With different numbers.
Capacities do not all perform the same. These are the official figures for each one, so you choose with the data in front of you.
| 1 TB | Read 14,900 MB/s · write 11,000 MB/s · 1.6 M IOPS · 600 TBW |
|---|---|
| 2 TB | Read 14,900 MB/s · write 14,000 MB/s · 2.3 M IOPS · 1,200 TBW |
| 4 TB | Read 14,900 MB/s · write 14,000 MB/s · 2.3 M IOPS · 2,400 TBW |
| 8 TB | Read 14,900 MB/s · write 13,200 MB/s · 2.2 M IOPS · 4,800 TBW |
COMPATIBILITY
06 / YOUR BUILDBefore you buy,check three things.
The SN8100 fits any M-key M.2 2280 slot. What changes is the speed you get and the free space it needs.
1. An M-key M.2 slot
2280 form factor (80 mm). The most common size on desktop boards.
2. PCIe 5.0 for its maximum
It works on Gen 4 or Gen 3, but the slot sets the speed.
3. Free space
With the heatsink it is 9.76 mm tall (11.25 mm on 8 TB). Check it does not clash with the graphics card.

FREQUENTLY ASKED QUESTIONS
What people ask us the most.
If you still have a doubt, write to us before buying.
Does it work on a PCIe 4.0 or 3.0 motherboard?
Yes. The SN8100 is backwards compatible with PCIe Gen4 and Gen3, but the slot sets the speed there: the up to 14,900 MB/s figures are only reached in an M.2 slot with PCIe 5.0 x4.
Which one should I choose: with or without heatsink?
If your motherboard already has its own M.2 heatsink, the bare model fits better. If it does not, or the slot sits under the graphics card, the anodised aluminium heatsink model holds sustained performance much longer, according to the manufacturer sheet.
Will it fit under my graphics card?
Without a heatsink it is 2.38 mm tall (3.88 mm on the 8 TB). With the heatsink it goes up to 9.76 mm (11.25 mm on the 8 TB): check the free space on your board before buying. The automatic check is below.
Is it valid for PlayStation 5?
Sony asks for an M.2 NVMe SSD with a heatsink. This heatsink model uses the M.2 2280 form factor, but FASE NUEVE does not publish a console compatibility list: check Sony official guide before buying.
What warranty does it have?
Five years of limited manufacturer warranty, or until the TBW limit of your capacity is reached, whichever comes first.
Why is the 8 TB without heatsink shown as unavailable?
Because we do not have it in stock today. The 8 TB with heatsink is available and appears in the selector.
