Purchase Criteria: How to compare 1tb external hard drives

Okay, if you've made it this far, you can already see the importance and usefulness of an external hard drive with 1tb of storage capacity. But now it's time to choose the best model among so many on the market. For this, it is necessary to understand what are the items that differentiate one option from another.

Therefore, we suggest that you analyze the following factors:

Below you check out how you should take into account each of these topics to invest your money in the 1tb external HDD that best suits your needs.


One of the most important criteria to consider when buying the 1tb external HD is the type of connection of the device. In fact, the external HD works with USB input, and may come accompanied by a USB cable or not.

The USB cables that come with the external HD 1tb can be used to attach it to other devices such as cameras, and in some cases even televisions. However, it is worth noting that the most modern 1tb external HDs have USB 3.0 connection, which determines the transfer rate.

And, although some models also allow USB 2.0 connection satisfactorily, the fact is that USB 3.0 input is three times faster. For example, today, most external 1Tb hard drives with USB 3.0 input guarantee a transfer rate of 5Gb, equivalent to about 625MB/s.

The connection with USB 2.0 cable, on the other hand, has a transfer rate of 480 Mb/s speed. The fact is that the type of connection, whether 3.0, 2.0 or even the most modern USB 3.1, eSATA or Thunferbolt, are responsible for the capacity of data transfer.


Although the type of connection is related to the capacity of data transfer, the speed of data transfer is a topic that deserves special attention.

The more RPMs the hard drive has, the faster it will process data.

After all, if you want an efficient 1tb external hard drive, you need to have a high speed when accessing the data stored on it. The speed on an external hard drive is measured in RPMs. So the more RPMs the hard drive has, the faster it will process the data and programs you have installed on it.

The slowest HDs usually have around 4200 RPM. The fastest models, on the other hand, have up to 10000 RPMs.

Operational system

Another factor you should consider when choosing the 1tb external HD is compatibility with the operating system of your computer or notebook. In general, Windows and Mac operating systems have the following file systems: NTFS and HFS+. And you will find 1tb external hard drives for each of them. Still, some models allow you to use the device in both operating systems.


Also take into account that some external 1tb hard drives have security systems, such as hardware-based or software-based encryption. Software-based encryption uses computer resources to encrypt the data.

So the external hard drive 1tb with this type of protection will be as secure as the computer. The external 1tb hard drive with hardware-based encryption relies on a chip that encrypts the information and therefore does not rely on the security of the computer to which it is connected.


Another factor you should take into account when choosing the best 1tb external hard drive is its size and weight. These are especially important if you intend to transport your external hard drive frequently. In this case, the smaller and lighter the better.

You can check the device's measurements and weight on the package description. To give you an idea, a 1tb external hard drive can weigh between 150g and 1kg. Remember that external desktop hard drives are even heavier.
