External hard drive buying guide

Using an external hard drive is a cost-effective way to save data outside of your computer's hard drives. It's also a sure-fire way to protect yourself from system crashes and other potential issues that can rob you of your files forever. However, to know which are the best external hard drives on the market, you need to have a repository, hence this buying guide. Without further ado, find out all you need to know about external storage.

What is an external hard drive used for?

Storing all of your files on your computer can be handy if you have enough storage space. But even if you are not yet at your storage capacity limit, or you don’t completely slow down your operating system, you run the risk of losing everything at any time.
The easiest and cheapest way to create backups of your data and host media files on the go is to use an external storage device, in this case, an external hard drive. This can take the form of a traditional mechanical hard drive (HDD) like the Seagate BarraCuda or a solid state drive (SSD) like the Verbatim Vi500.

External hard drive or Cloud?

To save money, you can simply trust an online storage solution or similar services with automatic backup to store all your files. However, in the case of OneDrive for example, this means that you depend on Microsoft not only to protect your files from the risks of piracy, but also to connect to your online storage (Cloud) if you want to access these files. on an unsynchronized device. And sometimes, it's difficult to sync accounts when the connection is unreliable.
On the other hand, backing up to an external hard drive allows faster and safer file transfer rates. The process is streamlined, with few failures thanks to high bitrates with a USB 3.0 interface, aside from perhaps a fault in the drive itself and the USB cable. There is also the concern of monthly cloud costs and available storage space. You will often need to pay a specific amount per month for cloud storage. Also, it might increase over time if you need more capacity. With an external drive, you only pay for the device itself.

External hard drive SSD or HDD?

Hard drives contain mechanical parts, including a magnetic disc and a read head. These large units (3.5-inch models) were traditionally used in personal computers before the advent of SSD technology. 2.5-inch hard drives are smaller and more compact, but they perform less well. Overall, they are not as durable as their flash memory counterparts (SSDs), but are significantly more affordable.
The SSD on the other hand is a flash memory storage and does not contain any moving parts. This removes a potential defect of the classic hard drive, namely the mechanical side of the latter. As a result, they are faster and consume less energy. Due to the lack of moving parts in SSDs, it is also possible to move them while they are transferring data to and from a computer without causing damage.

What size external hard drive to choose?

When it comes to the size of the external hard drive, it largely depends on what you want to store on it. The advantage of physical hard drives, as opposed to online storage services, is that you can always buy more drive space, or even get a NAS server for more storage space.
For thousands of images and music tracks, a few home movies, music, and documents, you can get by with 500 Gigabytes. That said, there's nothing wrong with wanting plenty of storage. To do this, a 2 Terabyte external hard drive allows you to have enough space for the future.

What are the points to consider before buying an external hard drive?

Depending on how much you are going to allocate to the purchase of your new external hard drive, there are three factors you should consider:

  • Transfer speed
  • This concerns not only the type of interface (USB 2.0, USB 3.0, eSATA), but also the rotational speed of hard disks (HDD). To have high speeds, it is advisable to choose an external hard drive running at 7200 revolutions per minute. As for SSDs, the transfer speed is not really affected. It varies depending on the type of flash memory it has on board or the technology used by the manufacturer.

  • Durability
  • If you need a durable external drive, opt for a model that can have a silicone case or sleeve. This type of accessory offers better physical protection.

  • Compatibility
  • An external hard drive could work in Windows, but could not be read in MacOS. Check if the manufacturer provides a solution for this.
