DatacenterNarrow moat

Sandisk (SNDK) — moat facet

From $325 million to $5.2 billion in two years, the only market where volume doubled.

Datacenter is the end market that changed Sandisk. It brought in $5,153 million in fiscal 2026, against $960 million in fiscal 2025 and $325 million in fiscal 2024.1 In the June quarter it was $2,977 million, 33.2% of revenue.23

One quarter of fiscal 2026 brought in three times fiscal 2025's whole year.

It sells enterprise SSDs to data centres, cloud providers and private-cloud customers, designed for servers, high-volume transaction processing and AI workloads.4

It is the one end market where volume grew strongly. Revenue rose 437%, or $4,193 million, with bits shipped up almost 120% and revenue per gigabyte up almost 150%.5 Both halves mattered: Sandisk shipped twice as much and was paid two and a half times as much for each unit.

It is also where the contracts are. The long-term agreements signed since April 2026 cover Datacenter and Edge customers, and the customers have posted deposits: refund liabilities were $1,500 million at year end, against $126 million a year earlier.6 The quarter's revenue rose 103% on the prior quarter.7

Sandisk competes here with the other NAND makers that sell enterprise SSDs; the joint-venture partner and the competitive field are argued under Competitors. Sandisk reports no profit for the end market.

The verdict is that this is where Sandisk has found demand that is not the consumer cycle, and it has grown faster than any other part of the company. The measure is its share of revenue, 33.2% in the June quarter: still rising in fiscal 2027 would show the contracts holding it up; falling when spot prices turn would show they did not.

Moat trajectory: Widening

Revenue up 103% on the prior quarter and under contract with deposits.

The number that tests this moat
Reported
Datacenter bits shipped, fiscal year
Up almost 120% in fiscal 2026 (revenue per gigabyte up almost 150%)

The only end market where volume doubled; that is what makes it a franchise rather than a price windfall.
