Identify how each application accesses data, how much performance and usable capacity it needs, what downtime and data loss the business can tolerate, and who will operate and protect the system. Then compare suitable architectures against those requirements and their full lifecycle cost.
How do I choose the right storage for my business?
Start with an inventory of the applications and data the business depends on. For each workload, record the access method it supports—block, file, or object—along with its protocols, client operating systems, read/write pattern, latency sensitivity, input/output operations per second (IOPS), throughput, and number of concurrent users. These characteristics matter more than a broad label such as “enterprise storage.” AWS’s storage decision guidance likewise recommends assessing workload latency, IOPS, access patterns, and throughput.

- Document workload requirements. Ask application owners and check vendor support documentation for required protocols and certified configurations. Separate workloads with different performance, access, or recovery needs instead of assuming one system must serve them all.
- Set capacity and growth assumptions. Estimate current data and forecast additions over a planning horizon. Synology’s vendor-authored NAS guide suggests looking two to three years ahead using existing consumption and expected growth; treat that as a planning approach, not a universal growth rate or industry benchmark.
- Define availability and recovery targets. Write down the acceptable data loss and downtime for each important workload before choosing resilience, backup, and replication features.
- Shortlist compatible architectures. Rule out options that do not support the workload’s access method, protocols, clients, or application requirements.
- Compare complete designs and costs. Use the same workload assumptions for every candidate, obtain sizing and support commitments for the actual configuration, and pilot representative workloads before a broad migration or purchase.
Do I need NAS or SAN?
NAS and SAN provide different kinds of access. Network-attached storage (NAS) serves files over a network; a storage area network (SAN) presents remote storage to servers as block devices, which the operating systems can treat much like locally attached storage. Direct-attached storage (DAS) is connected to an individual server or workstation. These are architectural distinctions, not a ranking from basic to best.

| Option | Access and workloads to assess | Key trade-offs and checks |
|---|---|---|
| DAS | Storage attached to one server or workstation, where local capacity and performance suit the workload. | Check whether limited shared-storage flexibility, availability, and expansion meet the application’s needs. |
| NAS / file storage | Shared files, file-based applications, or a local backup repository. | Check SMB or NFS and client compatibility, concurrent use, network throughput, drive bays, support, and scale. |
| SAN / block storage | Servers or applications that need block access and centralized allocation. | Validate latency, IOPS, network or fabric design, resilience, operating expertise, and total cost. |
| Cloud block | Volumes associated with cloud compute or database workloads that need block access. | Assess provisioned performance, availability, data transfer, pricing, and recovery design. |
| Cloud file | Shared read/write file access across cloud instances or on-premises servers. | Check protocols and clients, throughput, scale, migration path, and costs. |
| Cloud object | API-accessed content, read-heavy analytics, distribution, or archive patterns. | Confirm application compatibility, retrieval patterns, lifecycle and retention needs, egress, and protection. |
| Hybrid / edge | Workloads that need local access while using cloud-backed data or staged movement. | Plan for synchronization, outages, data mobility, compliance, and responsibility for operating both sides. |
Use the application’s requirements to decide between file and block access; do not choose SAN simply because a business is growing, or NAS simply because it is easy to recognize. Microsoft’s NAS and latency discussion is scoped to SharePoint Server, so its constraints should not be generalized to unrelated software. Confirm the supported design for each application with its vendor.

How much storage capacity will my business need?
Plan for usable capacity over the chosen horizon, not the sum of drive labels. Begin with current consumption and expected growth, then account for the space reserved or consumed by the selected resilience layout, snapshots, backups, retention policies, and performance headroom. The result should include an expansion path so routine growth does not force an urgent replacement or migration.
For a NAS, capacity is only one part of sizing. Compare drive-bay count and supported media, usable space after the chosen resilience layout, processor and memory capacity for concurrent workloads, network ports and link requirements, expansion support, and vendor lifecycle and support. A vendor selector can help narrow that vendor’s own product line, but it is not an independent benchmark or a substitute for workload sizing. Obtain confirmation that the proposed model and configuration meet the application’s availability and performance requirements.
Is cloud storage cheaper than on-premises storage?
There is no general cost winner established by storage capacity alone. Compare the cost of a complete design over the same period and workload assumptions. For cloud, include storage capacity, performance, availability, data transfer, backup or replication, and associated services. For on-premises systems, include hardware, support, administration, migration, electricity and cooling, protection, and refresh. Include staff time and the cost of operating any hybrid components.

Cloud bills may include transfer and related-service charges as well as storage capacity. AWS recommends selecting services for the workload and using its pricing calculator; obtain current quotes for the relevant region and configuration because service menus and prices change. For either approach, model likely growth and recovery requirements rather than comparing an undersized cloud estimate with a fully protected on-premises design.
How do I protect business data and recover it after an outage?
Set a recovery point objective (RPO)—the maximum acceptable amount of data loss—and a recovery time objective (RTO)—the maximum acceptable time to restore service. Define these for each critical workload, then choose a backup and recovery design that can meet them under realistic failures.
- Specify backup frequency, retention, and where protected copies will be held; consider off-site or cross-region copies where appropriate.
- Plan isolation so a compromise of the live environment cannot automatically compromise every recovery copy.
- Use replication where it supports continuity needs, but do not treat replication or RAID alone as an independent backup and recovery plan.
- Test restoration and record whether the recovered data and applications meet the RPO and RTO.
- Monitor protection jobs and failures so a missed backup or replication issue is visible before recovery is needed.
AWS describes scheduled backups and cross-region replication as options for continuity and compliance scenarios. NIST SP 800-209 addresses storage-focused protection, isolation, restoration assurance, and encryption. These measures help inform a design, but the business must establish and test its own recovery objectives.

Who is responsible for storage security?
Assign ownership for access control, encryption, compliance obligations, monitoring and logging, incident response, isolation, and restoration assurance. For cloud storage, distinguish controls the provider operates from controls the customer must configure or run. AWS describes cloud security as a shared-responsibility model: provider security foundations do not remove the customer’s responsibility to protect data and infrastructure. NIST SP 800-209, published in 2020, provides broader recommendations for storage infrastructure. Select controls according to data classification and applicable obligations; choosing a vendor by itself does not establish compliance.

What should I plan before migrating storage?
Choose a transfer method and schedule that fit the amount of data, available bandwidth, downtime constraints, and compatibility of the existing platform. Map application dependencies and lifecycle policies, and decide how encryption and access controls will protect data in transit and at rest. AWS notes that existing-platform compatibility and transfer constraints can affect migration strategy. Include the staff skills and operating processes needed for the destination, especially if both on-premises and cloud systems will remain in use.
Amazon Web Services’ Decision Guides page, last updated June 26, 2024, describes cloud block storage as low-latency storage associated with compute instances for applications needing fast, consistent I/O. That description is useful for evaluating a workload fit, not a universal guarantee about every storage service or configuration.
