Tips for external hard disks: What you should consider when buying
External hard disks offer a flexible way of storing and transporting data securely. There are a few things you should consider when buying to ensure long-term protection. From capacity and connection types to security features and the choice between HDD and SSD: there are many factors that influence how well your data is backed up and how long the hard disk will last in everyday use. In our latest blog post, we show you the important points you should consider in order to make the best choice for your requirements and avoid potential data loss.
Choose the right hard disk size
Storage capacity is a crucial factor: it should be large enough to conveniently back up your current data and cover future storage needs. Common options range from 1 TB to 4 TB, although professional users or media professionals often require even larger capacities. When choosing a very large hard disk, however, it should be borne in mind that a hard disk with more storage space also represents a higher risk of losing a large amount of data in the event of a defect. It therefore makes sense to also develop a regular backup strategy.
Pay attention to the connection speed
The speed at which data is transferred to the hard disk is crucial for many users. For fast and reliable data transfer, a hard drive with a USB 3.0 or USB-C interface is recommended. These standards offer significantly faster transfer speeds than older USB 2.0 ports. For particularly high speed requirements, e.g. for large video files, an SSD (solid state drive) instead of an HDD (hard disk drive) can also be useful.
Protect hard disk against physical damage
External hard disks are sensitive to shocks and drops – especially the classic HDDs, which consist of moving components. Even a slight impact can lead to data loss. If you transport the hard disk frequently, it is best to choose a robust, impact-resistant model or use a special protective cover. For particularly intensive use, such as outdoor work, there are also water and dust-protected versions that are certified according to the IP protection class.
Consider whether an SSD or HDD is more suitable
An SSD is a good choice when it comes to speed and shock resistance, as it does not require any mechanical parts. SSDs are ideal if you need to access large amounts of data quickly, e.g. for image or video editing. HDDs, on the other hand, usually offer more storage capacity at a lower price. Tip: If you use the hard disk as a long-term backup, a cheaper HDD may be perfectly adequate. For frequent, intensive use, however, an SSD is an option worth considering.
Use data security and encryption as additional protection
To protect sensitive data, many external hard drives offer the option of hardware encryption. This function ensures that your data is protected from unauthorized access even if the hard drive is stolen or lost. If you use the encryption function, make sure that the access key is stored securely. Important: If you need professional data recovery in an emergency, find out in advance whether your provider is able to recover encrypted hard disks.
Durability and quality: note the manufacturer and warranty period
An external hard disk is an investment, so you should pay attention to the quality and reputation of the manufacturer. Brand manufacturers often offer longer warranty periods, which speaks for the durability of the product. There are also providers who offer specific data recovery services in the event of a defect or have special software solutions for regular backups. It may be worth investing a little more in a high-quality model that offers a longer service life and better service.
The right choice for long-term data protection
An external hard disk can be an important shield against data loss – provided you choose the right model and take care when backing up your data. When buying, consider how often you will use the hard disk, what capacity you really need and how important speed and robustness are.
If a data loss does occur, it is reassuring to know that the experts at Datenretter Schweiz are at your side with professional data recovery. So you can be sure that your data is optimally protected – now and in the future.
