Slide 30: Data Center Storage: A Moment in Time (2025)
DATA CENTER STORAGE: A MOMENT IN TIME (2025)
This snapshot emphasizes portfolio risk and investment timing in storage decisions. Instead of one technology over time, it shows where the full storage stack sits right now.
LIFECYCLE POSITIONING:
| Stage | Technologies |
|---|---|
| Bleeding Edge | DNA Data Storage (Microsoft/Twist Bio), Glass Storage (Project Silica), CXL-attached Storage (CXL 3.0) |
| Leading Edge | QLC NVMe SSDs (60+ TB), Computational Storage (Samsung CSD), PCIe Gen 5 NVMe |
| Mainstream | TLC NVMe SSDs, SAS/SATA SSDs, All-Flash Arrays (Pure, NetApp, Dell), Object Storage (S3-compatible) |
| Trending Behind | High-capacity HDDs (20+ TB), Hybrid Flash Arrays, SAN (Fibre Channel) |
| End of Support | Consumer HDDs (< 4 TB), SAS 12 Gbps HDDs |
| End of Life | Tape Libraries (LTO-5 and earlier), 10K/15K RPM HDDs |
KEY INSIGHTS:
- HDDs appear in "Trending Behind" - they haven't disappeared but their role has narrowed to bulk/cold storage. The timeline view showed a long mainstream (30 yrs); the moment-in-time view shows that era is ending
- Multiple generations coexist: PCIe Gen 5 (leading edge) is shipping while SAS HDDs (end of support) are still in production - a 20+ year technology gap in active use
- The bleeding edge is radical: DNA and glass storage represent fundamentally different paradigms, not incremental improvements - suggesting a potential discontinuous jump
- Flash dominates the middle: TLC NVMe is the center of gravity today, just as HDDs were in 2005
DECISION LENS (RISK + CAPEX): Use this view to separate (1) technologies to expand, (2) technologies to contain, and (3) technologies to retire. The timeline explains historical motion; this slide supports current portfolio allocation.
Speaker notes
- "The timeline showed us one technology's journey. This companion shows the full competitive landscape at a single moment."
- "Notice how many technologies coexist simultaneously - from DNA storage in labs to 10K RPM drives being decommissioned. The lifecycle model explains why organizations must manage this complexity."
- "HDDs aren't dead - they're trending behind. That means plan your migration, don't panic. But also don't start new projects on them."
- "The bleeding edge here is fascinating: DNA and glass storage aren't incremental. They represent potential paradigm shifts, which is why they're years from mainstream."
