We are frequently asked whether a cheap USB hard drive can simply be used as a backup solution for a server. Short answer: No.
The Problem
USB hard drives are consumer products designed for occasional desktop use. They have no place in a data center environment:
- No redundancy: A single hard drive is a single point of failure
- No hot-swap capability: Replacing a drive requires physical access
- USB bandwidth: USB 2.0 is limited to approx. 30-40 MB/s — far too slow for large volumes of data
- No error correction: Consumer hard drives lack enterprise features such as end-to-end data protection
Professional Alternatives
- RAID storage: Redundant disk configurations on the server
- Network backup: Backup to dedicated storage systems over the network
- Remote backup: Encrypted backups to an off-site location
