Synology DiskStation 12 Bay DS2422+ NAS - Scalable Business Storage

Our review of the Synology DiskStation DS2422+ finds it a robust desktop NAS for small to midsize teams that need high-capacity, high-performance shared storage. The DS2422+ distinguishes itself by delivering substantial sequential throughput and flexible expansion options, making it a smart choice when the primary goal is storing and serving large data sets for multiple users, virtual machines, or surveillance storage. It is especially compelling for businesses that intend to add NVMe cache, 10/25GbE networking, or extra memory to squeeze more performance from a compact 12-bay chassis.

Key Features

• High sequential performance: The unit can deliver up to 2,201 MB/s read and 1,383 MB/s sequential write, which meaningfully improves large file transfers and VM storage responsiveness.
• Expandable capacity: Start with 12 drive bays and double to 24 bays by adding a single DX1222 expansion unit for growing archive or user data needs.
• Memory headroom: Support for up to 32 GB of RAM lets administrators scale multitasking, virtualization, and caching workloads without replacing the platform.
• Network and cache options: The ability to add 10/25GbE network cards or NVMe SSD cache provides clear upgrade paths to boost real-world throughput and latency for demanding environments.
• Versatile software use: Synology's ecosystem supports file sharing, backups, surveillance recording, and VM storage, making the DS2422+ a multipurpose server for small data centers.
• Warranty coverage: A three year warranty offers a reasonable support window for business deployments.

Who It's For

The DS2422+ is aimed at small businesses, creative teams, and IT pros who need dependable multiuser file serving, VM or surveillance storage on a compact desktop appliance and expect to grow capacity or performance over time. Its combination of strong sequential throughput and optional 25GbE or NVMe enhancements makes it suitable where shared access speed matters for large files or many concurrent users.

Those who should look elsewhere include users who only need a simple two- or four-bay backup box for a handful of desktops, or organizations that require fully redundant enterprise controllers and support contracts for mission-critical 24/7 operations; the DS2422+ is a high-end SMB device but not a full enterprise chassis.

Pros & Cons

Pros

• Strong sequential read and write throughput for large file and VM workloads.
• Expandable from 12 to 24 bays with a DX1222 expansion unit for long-term growth.
• Flexible performance upgrades via up to 32 GB memory, NVMe cache, and 10/25GbE networking.
• Good software versatility for file sharing, backup, surveillance, and VM storage.

Cons

• Sold diskless, so additional cost and configuration are required to populate drives and optional upgrades.
• Not positioned as a full enterprise-grade clustered controller for the largest, most critical data centers.

Frequently Asked Questions

Does the DS2422+ include drives?
The unit is sold diskless, so drives must be purchased and installed separately.

Can I expand storage later?
Yes, a single DX1222 expansion unit doubles capacity to 24 drive bays for growth over time.

Can performance be upgraded?
Yes; you can increase RAM to 32 GB, add NVMe SSD cache, or install 10/25GbE network cards to improve throughput.
