Does Owning Beat Renting Your Storage?

Home NAS vs subscription cloud at a glance

The cost and privacy trade-off

The headline difference is how you pay. A NAS is a one-off purchase: you buy the box and the drives once, and after that the storage is effectively free aside from a little electricity. Subscription cloud spreads the cost into a monthly fee you pay forever. At roughly 8 to 10 pounds a month for 2TB, a typical cloud plan adds up to around 100 to 120 pounds a year, so a modest NAS tends to pay for itself in about two years and keeps paying off after that. The more data you store, the worse the maths looks for subscriptions, because every capacity upgrade raises the monthly bill.

Privacy is the other big difference. With a NAS your files sit on hardware in your home, on your network, under your control. With a cloud service a third party holds your data, governs access to it, and can change terms or pricing. For many people that is a fair trade for convenience, but if privacy or control matters to you, owning the storage is a meaningful advantage. There is also speed: at home a NAS runs at full local network speed, while cloud is capped by your internet connection, which can make large transfers painfully slow on a typical home upload.

Why RAID is not a backup, and what 3-2-1 means

The biggest mistake NAS owners make is treating it as a backup when it is not. RAID protects against a single drive failing, it does nothing about fire, theft, flood, ransomware or accidentally deleting a folder, all of which take out the whole array. A NAS is your primary store, not your safety net. This is where cloud comes back into the picture, even for NAS owners.

The sensible rule is 3-2-1: keep three copies of your important data, on two different types of media, with one copy off-site. In practice that often means the working copy on your devices, the bulk on the NAS, and a small cloud backup of the truly irreplaceable files, your photos and documents, for the off-site copy. You do not need to back up your entire media library to the cloud. Backing up just the data you could never recreate keeps the subscription small and cheap while giving you genuine off-site protection that a NAS alone cannot.
