Sandisk shows a larger overall revenue base and a faster growth trajectory than ARM.
Over the past eight quarters, Sandisk's quarterly revenue has sky rocketed, while ARM's revenue has maintained a more stable pattern featuring minor sequential variations.
As these divergent financial trajectories continue to develop, prospective investors should carefully observe whether the current revenue gap between the two companies continues to widen or begins to narrow in upcoming quarters.

Sandisk is on a much sharper growth trajectory, largely due to higher selling prices for its products. Demand for artificial intelligence (AI) is extremely high for high-capacity solid-state storage. The key factor to watch for Sandisk is whether its long-term supply agreements with customers can remove the historical quarter-to-quarter volatility in selling prices and drive more stable revenue generation over the next several years.
ARM's revenue shows consistent year-over-year growth, although it fell sequentially in the second quarter. While ARM is known for supplying chip designs widely used in consumer devices like smartphones, it is gaining momentum in expanding into the data center market. This will be a key source of growth for the company.
Whether Sandisk can maintain its massive revenue size and continue to grow comes down to demand and selling prices for storage products. The more long-term agreements it signs and the more the AI infrastructure boom continues, the more likely Sandisk will continue to scale its business.
