In the digital age, having a good storage source is crucial due to the amount of information we handle. For this reason, our recommendation for today is in the area of hard drives, a topic that is not usually talked about much on the Internet and therefore generates many doubts when buying.
Today we bring you a guide that reviews basic information about hard drives, as well as updated and concise reviews so you can choose the one that best suits you. We also give you some of the most recognized and purchased brands.
Are you ready?
Hard drives are components used to store information. They are usually found in computers, cell phones, cameras, video game consoles, among other places. They are an alternative to cloud storage and you can take them with you anywhere.
Depending on your location, there are internal and external.
The internals must be in the body of the device to be used and are often included in prefabricated kits. External drives are used to store information that does not need to be accessed continuously, but allows it to be shared with other computers; Sometimes, they are considered as security resources to back up data that we do not want or can have on our computers. They are linked through an external USB or SATA connection.
Among the external drives are also multimedia drives designed to save and play different files: movies, photos, videos, songs, among others.
Hard drives according to their storage capacity
Currently, hard drives have a large memory capacity, adapting to the needs of all types of users. According to the amount of information that is going to be handled, we must decide if it will be chosen in Megabytes, Gigabytes or Terabytes.
1 Megabyte = 1024KB
1 Gigabyte = 1024MB
1 Terabyte = 1024GB
If you are looking to store little information, multimedia files and some documents, then hard drives with a capacity of 500 GB to 1 TB are ideal for you, since they offer enough space to store data of regular use.
Otherwise, if you are going to use it for the office or together with a professional device, we suggest you choose a hard drive with storage starting at 1 TB. If you are looking for something more geared towards saving a large number of files, those above 4 TB are more comfortable for various work environments.
Hard drives by size
Defined in inches as a reference to the size by which floppy disks used to be measured. Do you remember them, along with those big CPUs and monitors that took up too much space and weighed too much? Among the best known sizes of hard drives are those of 2.5 and 3.5 inches.
Most external hard drives are 2.5-inch, receive power through a cable that connects to your computer, and because of their small size, they can also be installed inside portable devices.
Now, the 3.5-inch ones, which are the ones that are regularly placed inside desktop computers, also exist in the form of external hard drives, but they need a cable to be able to be charged.
Interfaces for hard drives: internal and external
An interface is the connection point between two components. The speed of it will determine the speed with which the files are played or transferred.
Hard drives have two types of interfaces that are quite well known:
The SATA , intended for internal hard drives with later versions (SATA 3.0) that continue to evolve.
The USB , common in external hard drives thanks to its great compatibility. Newer versions allow a single port to be used to connect external devices.
What types of hard drives are currently on the market?
1 – HDD (Hard Drive Disk)
These are the quintessential conventional hard drives. They are computer components made with mechanical parts that use magnetism to record data permanently, which is why they also have the name of mechanical hard drives.
They are made up of one or more rigid disks that are attached to the same axis that rotates at high speed inside a metal box. The thinner the discs, the better the recording; the faster they spin, the faster the data transmission.
In general, the speed of these hard drives is usually 5,400 or 7,200 revolutions per minute, even so, some can reach up to 15,000 rpm. They have an average capacity of 256 GB and 4 TB and are the cheapest on the market. Their only drawback is how susceptible they are to damage.
2 – SSD (Solid State Drive)
These hard drives, also known as solid state drives, unlike HDDs, store information on microchips with interconnected flash memories. They are a good alternative to traditional hard drives and are considered a much more advanced evolution of USB sticks.
This type of hard drive has a built-in processor, also known as a controller that decides how to store, retrieve, and wipe the data on the drive. They are more efficient than mechanical hard drives, consume less power, have a faster transmission speed, and are quieter.
Their capacity ranges from 1 to 10 TB and despite being more expensive, they can be obtained at more affordable prices.
HDD vs SSD – Which to choose?
If you are looking to have a faster computer, we recommend the SSD . This type of hard drive also has the ability to revive old computers without the need for other components. It is also a good option for people who work in content editing or who are video game lovers.
On the other hand, if you are one of those who download a lot of things from the Internet, need a large amount of storage and have a regular budget, we suggest buying an HDD . They are also good external hard drive options. However, keep in mind that you will have more storage capacity than speed.
Best discs to use with video game consoles
We start by saying that SSDs are ideal allies for consoles.
For example, for PS4, in addition to the internal drive, an external drive with USB 3.o and up can be connected. It must have a minimum capacity of 250 GB and a maximum of 8 TB .
In the case of the Xbox or Xbox One , at least 256 GB with a USB 3.0 interface is required. In this console there can be two external drives connected simultaneously.
For both cases, we suggest 2.5-inch hard drives for convenience.
