3 Storage Devices Stocks to Buy in a Flourishing Industry

Demand for secure, high-performance storage is being driven by rising cyberattacks, rapid AI adoption and cloud-native architectures, prompting a shift to NVMe SSDs, object storage and storage-as-a-service; Gartner also reports worldwide PC shipments rose 8.2% in Q3 2025 and AI PCs are expected to account for 31% of shipments in 2025. Structural tailwinds are tempered by macro risks—trade tensions, supply-chain disruption and inflation—which could constrain near-term enterprise and SMB spending. The Zacks Computer‑Storage Devices industry has outperformed the S&P 500 (up 57.7% vs. 14.7% over the past year), trades at a forward P/E of 18.66x, and sits in the top 7% of Zacks industries (Rank #16). Zacks highlights three buy candidates: Western Digital (WDC) with ePMR/UltraSMR shipments >2.2M, fiscal Q2 revenue guide ~$2.9bn (+20%) and next‑gen HAMR plans; Sandisk (SNDK) with Q1 fiscal 2026 revenue $2.3bn (+23%), Q2 guide $2.55–2.65bn and persistent NAND tightness; and Teradata (TDC) with cloud ARR $633m (+11%), 109% cloud net expansion and tightened free cash flow guidance of $260–$280m—each carries a Zacks Rank #1 in the report.

Analysis

Rising cyberattacks and the rapid adoption of AI are creating clear structural demand for high‑performance, secure storage: the article cites a shift toward NVMe SSDs, storage‑class memory, object storage and software‑defined solutions to meet AI throughput and low‑latency needs. Gartner data cited shows PC shipments were up 8.2% year‑over‑year in Q3 2025 and AI PCs are expected to represent 31% of shipments in 2025, underscoring both enterprise and consumer catalysts for storage capacity and performance upgrades.

The Zacks Computer‑Storage Devices industry has materially outperformed the S&P 500 over the past year (up 57.7% vs. 14.7%) and carries a forward 12‑month P/E of 18.66x versus the S&P’s 23.35x and the sector’s 28.15x, suggesting valuation support for further upside but also historical volatility (5‑year range 9.84x–102.02x). Persistent macro risks—escalating trade tensions, tariffs, supply‑chain disruption and inflationary pressure—are flagged as potential near‑term constraints on SMB and enterprise spending.

Company‑level fundamentals favor leaders serving hyperscalers: Western Digital reported >2.2 million ePMR/UltraSMR shipments in the September quarter, expects fiscal Q2 revenue of ~$2.9bn (+/- $100m, +20%) and has multi‑year purchase orders from its top customers; Sandisk posted Q1 fiscal 2026 revenue of $2.3bn (+23%) with a Q2 guide of $2.55–2.65bn and $448m adjusted FCF amid tight NAND supply; Teradata’s cloud ARR was $633m (+11%) with a 109% cloud net expansion and tightened FCF guidance of $260–$280m, though its stock has lagged peers (-8.1% past year).

Key Decisions for Investors

• Increase selective exposure to leaders with direct hyperscaler and AI storage demand such as WDC and SNDK given strong shipment metrics and revenue guidance, while sizing positions to account for sector volatility
• Use the industry’s below‑market forward P/E (18.66x) as a rationale to add on meaningful pullbacks but avoid full allocation in a single trade due to the wide historical valuation range
• Monitor macro indicators—trade tensions, tariffs, supply‑chain signals and SMB spending—and be prepared to trim or hedge cyclical exposure if those indicators deteriorate
• Take a measured, smaller or catalyst‑linked position in Teradata to play cloud ARR growth while awaiting continued execution against its tightened free‑cash‑flow guidance
