Primary Storage
What is primary storage?
Primary Storage is the main area where data is stored for quick access. It’s faster and more expensive as compared to secondary storage, so it shouldn’t hold cold data.
Primary storage is typically the main data storage system in an enterprise that supports critical business operations, applications, and workloads. It is designed for high performance, low latency, and immediate access to data, making it essential for databases, virtual machines, and real-time analytics.
What are the Key Features of Primary Storage in the Enterprise?
- High Performance – Optimized for fast read/write speeds, ensuring smooth application and system performance.
- Low Latency – Reduces data retrieval time, which is crucial for transactional systems and real-time processing.
- Reliability & Availability – Often includes redundancy features like RAID, snapshots, and replication to ensure data integrity and uptime.
- Scalability – Allows businesses to expand storage as data grows without affecting performance.
- Integration with Cloud & Secondary Storage – Often works with secondary storage (for backup and archiving) and cloud solutions to optimize cost and efficiency.
What are the Types of Primary Storage in the Enterprise?
- Flash & SSD Storage – Used for high-speed applications like databases and AI/ML workloads.
- Storage Area Network (SAN) – High-performance block storage used for mission-critical applications.
- Network Attached Storage (NAS) – File-based storage ideal for shared access across multiple users.
- Hybrid Storage – A mix of SSDs and HDDs, balancing performance and cost.
- Cloud-Based Primary Storage – Primary data storage solutions hosted on cloud platforms like AWS, Azure, or Google Cloud.
What are some common primary storage strategies for enterprises?
- Data Tiering – Storing frequently accessed data on SSDs while moving less-used data to lower-cost storage.
- Backup & Disaster Recovery Integration – Ensuring primary storage works with secondary solutions for failover.
- Data Deduplication & Compression – Optimizing storage efficiency and reducing redundancy.
- Security & Compliance – Implementing encryption, access controls, and compliance measures for data protection.
- Automation & AI-Driven Management – Using intelligent storage solutions to optimize performance and detect potential failures.
Primary Storage With and Without Unstructured Data Management
| Evaluation Criteria | Without Unstructured Data Management | With Komprise |
|---|---|---|
| Visibility into primary storage | Limited to what’s on one array or vendor | Full analytics across multi-vendor NAS, SAN, and cloud |
| Response to DRAM/SSD price hikes | Buy more primary capacity as prices climb | Reclaim 70%+ of existing capacity through intelligent tiering |
| Tiering destination | Locked to the storage vendor’s own tiers | Any file, object, or cloud tier |
| Rehydration penalty | Required to access or migrate tiered data | None, data stays natively accessible |
| Data readiness for AI | Fragmented, untagged, hard to locate | Indexed and AI-ready at every tier |
Primary Storage Magic Quadrant
In the 2024 Gartner Magic Quadrant for Primary Storage Platforms, the Leaders were:
- Pure Storage (now EverPure): Recognized for the fifth consecutive year as the highest and furthest positioned leader.
- Hewlett Packard Enterprise (HPE): Achieved leadership status for the 15th consecutive time.
- NetApp: Maintained its position as a leader for the 12th consecutive year.
Other vendors in the Leaders quadrant include IBM and Dell.
A Blocks & Files overview noted that in 2024, Gartner redefined the criteria for primary storage platforms, emphasizing the need for platform-native services and hybrid cloud capabilities. This shift led to some vendors, such as Hitachi Vantara, Huawei, and Infinidat, moving from the Leaders quadrant to the Challengers quadrant. These changes highlight the evolving landscape of primary storage solutions, with a focus on integrated services and cloud adaptability.

Storage Newsletter described the changes to the Gartner Magic Quadrant Bizarre: Gartner Magic Quadrant 2024 for Primary Storage Platforms Bizarre.The analyst notes:
Year after year, Gartner MQ lost their ability to present a real snapshot of the market and continues to provide a wrong product and technology definition. Again a primary storage is not (only) a block storage but very often a block storage is used as primary. IT is just a storage used to support the business then having the primary role and this is independent of the media technology (HDD, SSD…), connectivity (FC, IB, Ethernet), access methods (block, file, S3, HDFS…), residence (on-premises, cloud, etc), subscription model and data nature (structured or non structured data). So Gartner should rename this MQ primary block storage.
In the 2025 Magic Quadrant for Enterprise Data Storage Platforms, Gartner noted:
The ESP market emerged at the convergence of two major trends: the adoption of the hybrid cloud operating model for on-premises mission-critical applications and the consolidation of two markets (primary storage platforms, and file and object storage platforms) into one market. This consolidation is in response to heads of I&O looking to simplify storage vendor management, drive cost synergies and reduce sourcing complexity by unifying multiprotocol access systems.
Primary Storage FAQs
Why are primary storage costs rising in 2026?
Enterprise AI infrastructure has driven surging demand for high-bandwidth memory (HBM) and high-capacity flash storage (NAND/SSDs), tightening supply just as data volumes keep growing. Gartner estimates combined DRAM and SSD prices will rise 130% by the end of 2026, with the shortage expected to continue into 2027. Because primary storage relies on this same flash and memory, the price surge lands hardest on the tier enterprises depend on most.
See Data Storage Costs for the full breakdown.
How can organizations address rising enterprise storage costs?
The most effective approach is to reduce how much data sits on primary storage rather than buying more of it. Most enterprises store far more than they use: typically 70% of unstructured data is inactive yet still occupies expensive primary capacity. Gaining visibility into that data, tiering inactive files to lower-cost storage, and automating lifecycle policies can cut primary storage costs significantly without a hardware refresh. Komprise Intelligent Data Management does this across multi-vendor NAS, SAN, and cloud primary storage.

How do I free up flash NAS capacity without buying more storage?
Identify the inactive data currently occupying flash-backed NAS and tier it automatically to secondary or cloud object storage. Komprise analyzes usage across primary storage, including NAS, and typically identifies 70%+ of capacity that can be freed this way, without the rehydration penalty of storage-vendor tiering.
See NAS Cost Savings for NAS-specific strategies.Should all data be stored on primary storage?
No. Primary storage is built for high performance and low latency, which makes it the most expensive place to keep data. Only active, frequently accessed data belongs there; inactive or cold data should move to secondary or archival storage. This distinction matters even more during a memory and flash price surge, since every inactive file left on primary storage occupies capacity at a premium price.
