About NAS and external HDD

NAS vs external HDD

Usually, when your computer runs out of free space, you start looking for the best deal to expand your space.

In most sources, external hard drives and NAS are the best solutions.

If the majority know about the former firsthand, then the second option is more abstract and less recognizable.

Often, many people think that only professionals use the NAS, and the setup of this device is very sophisticated. In fact, NAS or external hard drives are great options for increasing computer memory, which have their own nuances.

In this article, you will learn about each device in detail and also select the most suitable option for you.

Comparison between NAS and External HDD

In order to make the assessment objective, the most popular and necessary options will be considered external hard drive vs. NAS.

  1. 1. Compactness:
  • External drive: in this case, the external hard drive, of course, wins because its dimensions are minimal. This allows you to take this disc with you anywhere and have access to information at any time.
  • NAS: This device requires a fixed disk storage tank, as well as a permanent network and router. If all these are combined, it is unlikely that you will put it in your pocket and go on business. However, the ports on the computer will always be free. Therefore, make a choice depending on the above conditions.
  1. 2. The ability to access files:
  • External drive: this requires the physical presence of the drive and its subsequent connection to any computer. Since this is a portable medium, it is not difficult to do. However, if you forget it, for example, at home, then you will only have yourself to blame.
  • NAS: it has remote access. In other words, this stationary medium does not need to be carried on your back; you just need to know your account settings and access it anywhere in the world on any computer. You can also distribute data at your request to colleagues, friends, etc. Thus, NAS availability is superior to external hard drives.
  1. 3. The number of computers to operate the device:
  • External drive: here, you can apply the rule 1 computer = 1 external hard drive. It's simple - the computer in which the drive is connected is the only place you can work with its data.
  • NAS: thanks to the router, you can use several computers at the same time here. Through the network, any data can be transferred from one computer to another. It is handy for office workers and companies.
  1. 4. Data volume:
  • External drive: External hard drives come in various sizes, and if the volume runs out, you choose what can be removed. Or just buy a new external hard drive. That is, there is only a fixed volume, which cannot be increased.
  • NAS: You can place multiple hard drives in the NAS tank at once or add them as needed. Here, you can increase the volume and not be afraid that you will ever have to delete something. In terms of data volume, NAS has more features.
  1. 5. Possibilities of use:
  • External drive: in fact, it is just a device where data is stored and nothing else.
  • NAS: this device can be called a computer to some extent since data is not just stored here; it has a special OS. It is possible to install certain applications to control this system as you wish and need. With certain skills, NAS capabilities are colossal.

As you can see, the difference between NAS and external hard drive is palpable even in theory. Both devices are good, and after reviewing them, it will become much easier for you to choose one of them.

Data recovery comparison

If you have an external hard drive and you need to recover data, you can use DiskInternals Uneraser or DiskInternals Partition Recovery software.

If you need to recover data from a NAS, RAID recovery will be much better. But it depends on the number of disks and the type of RAID:

  • Sometimes for RAID 1 data recovery, DiskInternals Uneraser, Linux Recovery, and Partition Recovery can be enough, but RAID Recovery will be better. That highly depends on what file system you use.
  • In other cases of RAID data loss - use DiskInternals RAID Recovery.

All these applications are DiskInternals products; they have a free trial version and a paid license with the function of exporting recovered data for any storage medium of your choice. In addition, in any of these products, there is a function of Preview before recovery for free so that you can verify the quality and correctness of the scan results.

  • DiskInternals Uneraser is universal software for recovering music, photos, videos, images, documents, and more. Using the Wizard, you can select a quick or complete search for lost data. Recovery can be either certain types of files or all in a row.
  • DiskInternals Partition Recovery is a professional application for searching any data of any size on each disk partition individually. This search option gives you a better chance of finding lost data.
  • DiskInternals RAID Recovery is designed to recover data from RAID arrays (RAID 4, RAID 5, RAID 6, RAID 0, RAID 1, 0 + 1, 1 + 0, 1E, RAID 60 and JBOD). It is possible to mount virtual disks in local ones for convenience. This application also has the service of creating a disk image. RAID Recovery™ examines the current controller, file system, drives, and automatically restores files where possible.

Each DiskInternals application is designed, taking into account the capabilities and wishes of customers with maximum support in the data recovery process.
