external hard drive purchase guide; Everything you need to know before buying

It is a computer, but with the difference that you can easily hold and move it. Of course, transporting all external hard drives is not easy, and for example, some of them are very large and heavy, which we will discuss further. Before buying an external hard drive, you must first choose between SSD or HDD.

SSD vs HDD

At the very beginning, we have to say that SSD hard drives are significantly faster than external HDD drives, and as a result, they have a higher price. HDDs use rotating magnetic disks to store data, and the read and write head can add or delete desired information from the disk. During the rotation of this head, a special sound is produced, which if you have an external HDD, you are well familiar with this sound. These types of hard drives have a lower lifespan, speed, and quality than SSD models, but thanks to the better price, many users still prefer to buy these types of hard drives.

But instead of moving parts, SSD external hard drives use memory chips and advanced transistors, and the technology used for them is somewhat similar to the technology used in flash memories. . Although these types of hard drives have a higher price than HDD models, they bring higher speed and durability and are usually smaller than HDD models.

So if the durability, speed and size of the external hard drive It is very important to you, so you have no choice but to buy an external SSD hard drive. But on the other hand, due to their lower price, HDDs provide you with a higher capacity for a lower price.

External hard drive Capacity

For almost all users, external hard drive capacity is the most important criterion they consider. Undoubtedly, even if an external hard drive has high speed and quality, if it offers a low capacity, it will not be very useful. On the other hand, if the capacity of an external hard drive is more than you need, then you just wasted your money. But what capacity is sufficient for the external hard drive depends only on your needs.

If you just want to transfer a few tens of gigabytes of files between different systems, a high-speed flash memory with a capacity of 32 or 64 GB can probably meet your needs. On the other hand, if you are a photographer or videographer and You plan to archive a large amount of data, so you should use external hard drives with a minimum capacity of 2 TB.

Transfer speed

Giant external hard drives with a very high capacity are not necessarily the right choice because these types of hard drives may have a low transfer speed and you have to wait a long time to move information through them. In this context, two issues are very important; The technology used for the desired external hard drive and the built-in connector for it.

In terms of speed, SSDs are generally faster than HDDs, and as we said above, SSD models are more expensive. Various standards are used in the field of suitable connector for connecting external hard drive to system or phone and tablet. Although almost all external hard drives use the USB port, we must note that USB also has various standards. For example, USB 2.0 is an old standard, so if you only use an external hard drive to move small files, we recommend using it, otherwise it's better to stay away from this standard. In general, the maximum data transfer speed with this port reaches 480 megabits per second, and usually the USB ports based on this standard in the computer are not colored. . For example, you may see in the list of specifications of different hard drives that these hard drives use USB 3.0, USB 3.1 Gen1 or USB 3.2 Gen1 ports, but practically all these standards have the same specifications and usually offer a maximum speed of 5 Gbit/s. We should note that the ports based on this technology are usually blue in the computer. USB 3.1 Gen2 and USB 3.2 Gen2 are similar and bring a maximum speed of 10 Gb/s, and red color is used for these types of ports in computers. USB 3.2 or 3.2 2x2 provide a maximum speed of 20 Gbps.

Usually for The standard used uses the term port, but the word connector is used for the appearance of this interface. Most external hard drives use a USB-A connector, which is the common form of a USB port, and you can only insert the connector in one direction. On the other hand, in recent years, the popularity of USB-C has multiplied, which is much smaller, and you no longer need to pay attention to its direction to insert the connector into this port.

The DisplayPort protocol used for data transfer audio and video are used, it uses the USB-C connector, and sometimes, although we see the use of USB-C, in fact the Thunderbolt 3 or Thunderbolt 4 protocol is used, which allow up to a maximum transfer speed of 40 Gbps. There are also very old external hard drives with connectors like eSATA and Firewire, which are better to avoid.

Finally, to take advantage of the maximum speed of the external hard drive, you should buy an SSD hard drive with a Thunderbolt connector so that you can Benefit from the highest speed.

Durability and portability

Almost all users use small and compact external hard drives called 2.5 hard drives. They use inches, which are not large in size, and as a result, they are very easy to move. These types of hard drives use the same USB cable for power supply, and therefore there is no need to connect to a separate power source for them.

But on the other hand, people who are looking to buy an external hard drive with a capacity of more than 2 are terabytes, they usually choose from desktop hard drives that are mostly placed vertically on the table and you have to provide a separate power source for them. Besides this, we should not forget the durability of the external hard drive.

If you are one of the people who want to take the external hard drive to different places, it is better to buy an external hard drive with a durable body. In this context, SSD hard drives perform much better because they have no moving parts and show more resistance to impacts. Of course, some HDD models can provide high resistance due to their special design, but in general, to benefit from more resistance, we recommend buying SSD models.

Security

Although using Special encryption software, you can encrypt the information of all kinds of external hard drives, but only some of these hard drives offer the possibility of hardware encryption. Therefore, if the security of the information on the external hard drive is very important to you, you should choose among models with hardware encryption capabilities. Also, on the other hand, we should mention some expensive external hard drives that have There are fingerprint sensors.

Warranty

Warranty is another important point that you should pay special attention to when buying an external hard drive. If the company in question does not provide a proper warranty, in case of damage to the hard drive, you will probably not be provided with a new external hard drive. But on the other hand, well-known and high-quality warranties replace the broken hard drive and provide you with a new one. We should also mention data recovery services that are provided to users for free by some guarantees. Therefore, just because an external hard drive is cheap, don't ignore the importance of warranty.
