NAS and external hard drives are both popular for storing and backup. However, do you know which one is better? The next part will compare their features, and you may find the answer.
NAS or External Hard Drive for Backup: Which One Is Better?
As mentioned above, both NAS and external hard drives are good for backup and storage. But which one is more convenient and smarter? This part will tell you the answer.
Cost
- The prices of external hard drives differ for different capacities. An external hard drive of 4 TB usually cost 90$.
- With its latest technology, advanced features, and colossal setup, NAS is more expensive as compared to traditional data storage methods. A NAS of 4 TB usually costs 370$.
Capacity
- Users can not expand the capacity of the external hard drive and get more capacity unless they buy a new one.
- NAS provides bays and allows users to attach extra hard drives to the network, so a NAS can provide more capacity than an external hard drive.
Speed
- The speed of USB 1 is only 12 MB/sec, while that of USB 4 can be up to 40 Gbits/sec.
- The typical speed of transferring data ranges from 3MB/s to 20MB/s for consumer-level NAS devices.
Accessibility
- Users need to plug in the external drive to a compatible port on a computer or other device before they can access the data they need.
- Most NAS provides Cloud service and allows users to access files remotely, without any contact, as long as they have an account setup.
Portability
- External hard drives are usually small, compact, and built to be easily conveyed around. They don't need internet connectivity or power backup.
- NAS usually comes in boxes and needs more space. It can not work unless users plug it into a power source and router.
Flexibility
- The external hard drives can store files, media, and other documents as other storage devices can.
- NAS is more flexible. It comes with a fully functional operating system, RAM, and support for first and third-party applications.
Data Backup and Recovery
- External hard drives do not provide automatic backup features, so users need to find another hard drive to save the data while backing up the external hard drive.
- Some NAS devices automatically back up the data already stored in NAS, making recovery easier.
Convenience
- Using an external hard drive requires users to shuffle the drive from computer to computer to access files.

NAS is commonly used by enterprises for sensitive data, and it is important to set up a backup for NAS devices to ensure you can recover data to avoid data loss. We should never consider them as a backup solution only. Since they are intended as storage devices, some businesses mistakenly use them as backup solutions.

Besides, external hard drives are usually portable, while a NAS typically comes in the form of a box. If you are going to travel, you can't take a NAS with you. Therefore, both NAS and external hard drives are good storage devices and have their own features. They are independent and can not replace each other, at least within a short time.
NAS or External Hard Drive for Backup: Verdict
To wrap up, NAS and external hard drives have advantages and limitations. NAS is smarter and more intelligent compared with traditional storage devices. At the same time, it also occupies more space than an external hard drive. On the other hand, external hard drives are portable and not easily attacked. This page compares them in many aspects.
