Although it is true, a refers to that device of the system of memory of a computer that, by default, used to store all user programs, applications and files. Since it is the only element with the ability to save data at all times (even when it is not powered by electricity).
That is why, the main characteristic of a hard disk lies in its storage arrangementbecause the larger it is, the more programs, documents, photographs, movies and songs a file can contain. pc. Besides, his speed it is also essential because influences the boot time of the machine and softwares.
Now, since there are a variety of hard drives that must be differentiated, it is important point out and detail which are each of them in order to know their most interesting particularities. Reason why, here we offer you a list with the kinds of hard drives that are on the market.
Types of hard drives How are these hardware classified and how are they different?
First of all, it should be noted that the hard drives they differ from each other depending on their different classifications. Since, although they are mainly sectioned according to its internal technologyalso distinguish between some classes of hard drives depending on their interface or the type of connectors they uselike by their location or the place where they are.
In this sense, we begin by defining the two types of hard drives that are known based on their internal technology, taking into account that each of them can use different kinds of connectors:
HDD hard drives
They are also known as “mechanical hard drives” or “magnetic hard drives” and, basically, they are the most traditional on the market because they have the ability to record information magnetically through one or more plates or disks. So, they have a similar operation to a small record player.
So, HDD hard drives They are characterized by being formed, mainly, by mechanical parts in which several rigid plates rotate at high speed around an axis located inside a box.. In this way, a head on each disk will be in charge of reading or writing data on each of its faces. It is also necessary to highlight that, They are the cheapest and most durable.so they have been used for decades.
SSD hard drives
These are also called “solid state drives” and are those that, instead of using spinning discs to fulfill its fundamental objective of saving data, use transistor arrays. In such a way that, each of said transistors deals with store a unit of information and since there are no moving parts, access is much faster.
Therefore, the devices have nothing to do with the classic discs HDD and are only included within the same classification, because engaged in similar trades. On the other hand, thanks to the fact that they have the advantage of consume less power, are more shock resistant, exhibit faster speed, and do not produce substantial noisehave been the most successful hard drives in recent years.
Nevertheless, they are more expensive hard drives and have less storage capacity than HDDs. Therefore, many people have chosen to use a ssd for run a computer’s operating system and, in addition, reserve a HDD for data storage exclusively. On the other hand, hard drives They are also classified depending on their connectors or their interface.
Next, we mention what each one of them is:
SATA hard drives
They are those hard drives that are used in household equipment, mostly, that is, on desktops or laptops. which, too They are called “Serial ATA hard drives”. and are characterized by use a serial connector responsible for carrying out data transmission. In general terms, they are distinguished by operating with a speed close to the 150 megabytes per second, mostly.
In that sense, it is hard drives with great popularity in the world of computing and, therefore, refers to one of the most used in recent years. Highlighting that, it provides advantages around its data transmission speed and its price.
It should also be noted that there are three kinds of SATA hard drives and they are:
- SATA-1: This achieves a speed of up to 150MB of data transfer.
- SATA-2: It can reach a transfer speed of up to 300MBthat is, double that of SATA 1.
- SATA-3: In view of achieves a transfer speed of up to 600 Mbis classified for exhibiting a higher performance and it is the most requested in relation to the others SATA. In addition, its size is small and, even so, it guarantees large capacity.
SAS or SCSI hard drives
Usually, consists of hard drive connectors that are used at a professional level and, therefore, are ideal for environments of high performance. Among its main peculiarities, we find that are capable of replacing other similar hard drives without having to turn off the computer. Therefore, it allows the service to continue operating normally and without any interruption.
For their part, both hard drives SAS as well as the SCSI are usually found inside blades or racks and are installed in RAID. However, in the case of SASstand out for being the most used in servers and can cover up to 24 computers because it is possible to connect them 6 or 7 meters away. Secondly, the SCSI they require a driver to operate and have a small interface.
Apart from all these kinds of hard drivesare also known those that are sectioned depending on their location. Therefore, they are the internal and external disks, basically.
Which are defined as follows:
internal hard drives
As their name indicates, they are those discs that are located inside the computer case or system cabinet. Among its most important particularities, we define that uses a magnetic recording system with the objective of store digital data found inside any laptop or desktop computer.
Added to this, an internal hard drive focuses on using the energy provided by the system itself. However, taking into account its benefits, we emphasize that offers greater storage capacity, is faster and more accurate in reading data and has remarkable durability.
External hard drives
In this case, it is a hard drive that connects to the computer via external USB or SATA connection. Thus, they are ideal for save data or information that should not be used every day or constantlybecause they are slower devices.
Among its greatest advantages, we find that they allow perform optimal full system backup and offers the possibility of storing very large files, without this influencing the performance of the computer. Therefore, they exhibit less hard drive clutter and ensures greater portability.
Whereas, so They are used to add additional capacity to a piece of equipment. and they are also commonly used for audiovisual content players in TV.
List of the best hard drive manufacturers on the market that you should know
Once all the above information has been clarified, users will be able to count on a more relevant notion of the hard drives of your computers. But, when purchasing any of them, it is also of great importance to choose a quality manufacturer.
Therefore, here we will mention the best industrial hard drives on the market today:
hgst
This is one of the most recognized brands when selling or marketing computer products and services is, especially, around hard drives and solid state drives, as well as external storage. which comes from Western Digital and has been operating since 2003.
Among its main hard drives and solid state devices, we find the following:
- ultrastar.
- Deskstar.
- Travelstar.
- Endurastar.
- Cinemastar.
Seagate Technology
It refers to a american brand that manufactures hard drives worldwide and these are used in a variety of computers, be it desktop computers, servers, laptops and even other consumer devices such as video game consoles, for example. Thanks to his remarkable career, has been the largest and oldest manufacturer of hard drives in the world.
In general, it offers hard drives with great speed ideal for computers, laptops, mobiles and external storage.
