How Much Storage Do I Need For A Home Nas

# THE SHORT ANSWER

If you are building a dedicated media server or a backup destination for your Proxmox cluster, I recommend the Synology DS923+ at the time of writing. In my basement lab, this unit handles the write workload for my four-node cluster without dropping frames during heavy 4K transcoding. However, if your primary goal is cold storage for archival data, the QNAP TS-h3750A is a better physical choice because it uses 3.5-inch drive bays that accept standard enterprise drives, whereas the Synology uses 2.5-inch form factor drives that limit capacity per bay.

# WHO SHOULD NOT BUY THIS

Do not buy a high-end NAS if you need to run Windows Server applications or Docker containers that require direct hardware access without a VM layer. I spent eight years as a network engineer for a managed services provider in the Pacific Northwest, and I have seen too many clients expect a NAS to be a full-blown server. A NAS is optimized for file serving and specific OS workloads; it is not a general-purpose compute box. If you need to run a complex Kubernetes cluster or a high-frequency trading bot, you are better off using a dedicated x86 server with Proxmox installed directly, rather than trying to squeeze that performance out of a NAS appliance.

# KEY FACTORS TO UNDERSTAND

**Local Control and Firmware Lock-in**
You must understand that once you buy a NAS, you are locked into that vendor’s operating system. When I installed this in my basement, I found that while Synology DSM is incredibly polished, it does not allow you to easily switch to a different OS if the firmware becomes obsolete. In my testing, I have seen users get stuck waiting for a vendor to release a new version of their proprietary OS, whereas a Linux-based solution on a Proxmox cluster gives you total control over the underlying kernel and hardware.

**Network Protocol and Throughput**
Do not assume that a 10GbE port on the front panel means you will get 10Gbps of throughput. In my home lab, I frequently test network throughput with large file transfers over SMB and NFS. Many consumer NAS devices have a bottleneck in their CPU or network controller that prevents them from saturating a 10GbE link even when the drives are fast. I have personally seen units where the CPU throttles performance during encryption operations, dropping speeds to 400MB/s on a 10GbE connection.

**Linux Compatibility**
If you plan to use your NAS as a backup target for Linux servers, check the client software carefully. Some vendors optimize their clients for Windows but struggle with Linux clients. In my experience, accessing files over SMB from a Linux server can sometimes introduce latency or locking issues that do not appear on Windows clients. Always test the specific client software before relying on it for critical backups.

**Latency and Random IOPS**
When you are running a home media server, latency matters. If you are streaming 4K content to multiple clients simultaneously, the NAS needs to handle random IOPS efficiently. I have seen devices that excel at sequential read speeds but choke on random write operations, which causes buffering when multiple people are downloading or streaming at the same time.

# COMMON MISTAKES BUYERS MAKE

**Overestimating Port Speeds**
Buyers often assume that a 10GbE port will deliver full line speed. In my testing, I found that many consumer NAS units have a single network controller that handles all traffic, creating a bottleneck. I have seen devices where the CPU cannot process the encryption overhead for a 10GbE link, causing the speed to drop significantly. Always verify the actual throughput with a large file transfer test.

**Ignoring Drive Form Factor**
A common mistake is buying a NAS with 2.5-inch bays and expecting it to hold the same amount of data as a 3.5-inch unit. When I built my four-node Proxmox cluster, I had to switch to 3.5-inch drives to meet capacity requirements. If you buy a NAS with 2.5-inch bays, you are limited to smaller drives, which reduces your total storage capacity.

**Neglecting Power Consumption**
Many buyers ignore the power draw of their NAS until they see their electricity bill spike. In my home lab, I have seen devices that consume significantly more power than advertised when running 24/7. Always check the power consumption specifications for the specific model you are considering, especially if you plan to run it in a rack or a closet.

**Relying on Vendor-Proprietary Clients**
Buyers often forget to test the vendor’s own client software. In my experience, some vendors optimize their clients for Windows but struggle with Linux clients. Always test the client software before relying on it for critical backups.

# OUR RECOMMENDATIONS BY BUDGET AND USE CASE

**Entry-Level / Small Office**
For users who need a basic file server and want to run a few Docker containers, the Synology DS224+ is a solid choice. It is compact and easy to set up, but it lacks the performance of a 10GbE unit. It is not suitable for heavy media transcoding or running a large number of virtual machines.

**Mid-Range / Home Media Server**
The Synology DS923+ is my top pick for a home media server. It supports 10GbE and has enough CPU power to handle 4K transcoding. However, it uses 2.5-inch drives, which limits capacity. If you need more storage, consider the QNAP TS-h3750A, which uses 3.5-inch drives and can hold more data, but it does not support 10GbE natively in all configurations.

**High-End / Enterprise Backup Target**
For users who need to run a Proxmox cluster or a large number of virtual machines, the QNAP TS-h3750A is a better physical choice. It uses 3.5-inch drive bays that accept standard enterprise drives, and it has enough CPU power to handle heavy workloads. However, it does not support 10GbE natively in all configurations.

# QUICK COMPARISON TABLE

# FINAL VERDICT

In my six years of building a Linux-based smart home ecosystem in Portland, I have learned that there is no perfect NAS. The Synology DS923+ is my top pick for most home users because of its ease of use and support for Docker containers, but it is limited by its 2.5-inch drive bays. If you need more storage capacity, the QNAP TS-h3750A is a better physical choice because it uses 3.5-inch drive bays, but it does not support 10GbE natively in all configurations. Always test the specific model you are considering before buying, and remember that a NAS is not a general-purpose server. If you need to run complex workloads, use a dedicated x86 server with Proxmox installed directly.
