Vaše stolno ili prijenosno računalo ima širok izbor priključaka i vrsta povezivanja, ali čemu sve služe i po čemu se razlikuju? USB 2.0 , USB 3.0 , eSATA, Thunderbolt , Firewire i Ethernet neke su od tehnologija koje su ugrađene u mnoga računala koja se danas prodaju. Dakle, koja je najbrža vrsta veze? Koju vrstu veze je najbolje razmotriti za vanjski tvrdi disk? Što je s podrškom za 4K više monitora? U ovom ćemo članku govoriti o različitim vrstama podatkovnih portova velike brzine i kako se koriste.

Bez obzira na to koju vrstu računala imate, vjerojatno imate jednu ili više vrsta brzih veza obuhvaćenih u ovom članku. Pogledajmo najprije različite brzine za svaku vrstu veze. Imajte na umu da nazivne brzine nisu ono što ćete dobiti u stvarnim uvjetima. Najvjerojatnije ćete moći postići bilo gdje od 70% do 80% navedenih maksimalnih brzina.

Ubrzati^(Speed)

USB 2.0^{(The USB 2.0)} vrsta veze prilično je postala standard. Vjerojatno ste u nekom trenutku koristili USB 2.0 kabel za povezivanje nekog uređaja ili pogona na svoje računalo ili Mac i vjerojatno imate nekoliko rezervnih USB kabela po kući. Iako je USB 3.0 tu, mnogi periferni uređaji i drugi uređaji se još uvijek proizvode s USB 2.0 povezivanjem.

Mnogi uređaji još ne koriste USB 3.0, niti Thunderbolt . Zašto? Budući da je USB 2.0 jednostavno dovoljno brz za rješavanje manjih zadataka i mnogi uređaji jednostavno ne zahtijevaju munjevitu brzinu, kao što su miševi i tipkovnice. OK super, koliko je točno USB 2.0 ?

USB 2.0 is rated at 480Mbps. That’s about 60 megabytes per second. For quick reference, 1000 Mbps equals 1 Gbps, which is considered gigabit.

Vrsta veze USB 3.0 sljedeći je korak za ^{( USB 3.0)}USB (od 2.0). Brzine prijenosa USB^(USB) 3.0 su oko 10x brže od prethodnih USB 2.0 brzina. Dakle, što to znači?

USB 3.0 is rated at 5 Gbps. That’s about 640 megabytes per second. 

2013. godine također je objavljen USB 3.1 koji ima brzinu do 10 Gbps . To je oko 1280 megabajta u sekundi ili 1,2 GB u sekundi. To znači da je USB 3.1 brz kao jedan Thunderbolt kanal prve generacije.

Također je vrijedno napomenuti da će nova USB Type C veza podržavati USB 3.1 za maksimalnu brzinu prijenosa podataka od 10 Gbps .

eSATA je skraćenica za vanjski SATA . SATA je, naravno, vrsta veze koja se koristi za spajanje unutarnjeg tvrdog diska na računalo. Dakle, unutar vašeg desktopa ili prijenosnog računala nalazi se tvrdi disk, koji se u većini slučajeva povezuje s matičnom pločom pomoću SATA sučelja.

Uz eSATA, vanjski tvrdi disk može koristiti istu vrstu veze i tehnologiju za povezivanje s računalom. Tvrdi disk unutar računala brži je od standardnog vanjskog tvrdog diska ( USB 2.0 ), pa kakve brzine proizvodi eSATA?

eSATA is rated at 3 Gbps and 6 Gbps.

Thunderbolt kabeli najnoviji su tip veze na ovom popisu. Izvorno pod kodnim imenom “ Light Peak ” , Thunderbolt je prva tehnologija koju je razvio Intel . Za Thunderboltov^{(Thunderbolt)} debi za potrošače, Apple Inc. dodao je sučelje velike brzine na gotovo sve svoje uređaje u Mac liniji, što ih čini jednom od prvih tvrtki koje koriste tu tehnologiju. Thunderbolt je sposoban za više od ostalih vrsta povezivanja, ali ćemo na to doći kasnije. Koje brzine Thunderbolt proizvodi?

Thunderbolt is rated at 10 Gbps per channel (x2). Thunderbolt 2 raises that value to 20 Gbps over a single channel. Thunderbolt 3 doubles the bandwidth again to 40 Gbps. 

Firewire ili IEEE 1394 je još jedna vrsta veze koja je neko vrijeme bila popularna, ali je nekako nestala tijekom posljednjih nekoliko godina. Popularnost USB 2 i USB 3 uređaja usporila je usvajanje Firewirea^(Firewire) , što je rezultiralo sporim opadanjem veze. To se dogodilo iako su Firewire 400 i 800 brži od prethodnih USB tehnologija (ne uključujući 3.0).

Firewire is rated at 3 Gbps (400) and 6 Gbps (800).

Ethernet je vrsta veze koja se uglavnom koristi za umrežavanje, pa nije dizajnirana da bude superbrza. Međutim, Ethernet kabeli se također mogu koristiti za prijenos računalnih podataka.

Ethernet is rated at 100 Mbps.

Sažetak^(Summary)

Da sumiramo gore navedene podatke, vrste veze rezultirale bi sljedećim, od najbržih do najsporijih.

1. Thunderbolt (do 40 Gbps)^{(1. Thunderbolt (up to 40 Gbps))}

2. USB 3.1 (10 Gbps), zatim USB 3.0 (5 Gbps)^{(2. USB 3.1 (10 Gbps), then USB 3.0 (5 Gbps))}

3. eSATA (6 Gbps)

4. Firewire (6 Gbps)

5. Gigabitni Ethernet (1 Gbps)^{(5. Gigabit Ethernet (1 Gbps))}

6. USB 2.0 (480 Mbps)

7. Ethernet (100 Mbps)

Međutim, ova analiza nije sasvim točna. Kao što je ranije spomenuto, u stvarnim situacijama, mnoge od ovih maksimalnih brzina rijetko se postižu. Ovdje je grafikon s Wikipedije^(Wikipedia) koji sažima specifikacije za mnoge vrste veza osim onih koje sam spomenuo.

Prilikom kupnje vanjskog uređaja ili novog računala, glavna stvar koju treba uzeti u obzir je verzija vrste veze. Na primjer, ako kupujete novi Retina MacBook Pro prijenosno računalo, primijetit ćete da ima USB 3.0 port i Thunderbolt 2 port.

Ako malo odgodite, Apple će vjerojatno uključiti novije Thunderbolt 3 veze u svoje najnovije MacBookove, što znači da s tim portovima možete učiniti puno više nego prije. Na primjer, uz Thunderbolt 2 na svoje računalo možete povezati do jedan 4K zaslon na 60 Hz ili dva 4K zaslona na 30 Hz. Uz Thunderbolt 3 moći ćete spojiti do tri 4K zaslona na 60Hz ili jedan 5K monitor na 60Hz.

Ethernet je iznimno spor i može se koristiti za prijenos datoteka i premještanje mapa, ali njegova je glavna namjena za lokalno umrežavanje.

Po mom mišljenju,  Thunderbolt i USB 3.1 ( Tip C^{(Type C)} ) će s vremenom postati standard na većini računala. Pružaju najveću brzinu s dodatnim značajkama kao što su dvosmjerno napajanje i podrška za više monitora. Osim toga, obje tehnologije već su usvojili mnogi veliki proizvođači računala.

USB 2.0 vs. USB 3.0 vs. eSATA vs. Thunderbolt vs. Firewire vs. Ethernet Speed

Your desktop or laptop computer haѕ a wide variety of ports and conneсtion types, but what аre they all for and how do theу differ? USB 2.0, USB 3.0, eSATA, Thundеrbolt, Firewire, and Ethernet are some of the technologies that are built into many of the computers sold today. So, what’s the fastest connection type? What type of connection is best to consider for an externаl hard drive? What about for 4K multi-monitor support? In this article, we’ll talk about the different types оf high-speed data ports and how they are υsed.

No matter what type of computer you have, you probably have one or more of the high speed connection types covered in this article. Let’s first take a look at the different speeds for each type of connection. Note that the rated speeds are not what you’ll get in real-world conditions. Most likely, you’ll be able to get anywhere from 70% to 80% of the max speeds listed.

Speed

The USB 2.0 connection type has pretty much become the standard. You have likely used a USB 2.0 cable to connect some device or drive to your PC or Mac at some point and you probably have several spare USB cables laying around the house. Even though USB 3.0 is here, many PC peripherals and other devices are still being manufactured with USB 2.0 connectivity.

Many devices do not yet use USB 3.0, nor do they use Thunderbolt. Why? Because USB 2.0 is simply fast enough to handle minor tasks and many devices simply do not require lightning fast speed, such as mice and keyboards. OK great, so how fast is USB 2.0 exactly?

USB 2.0 is rated at 480Mbps. That’s about 60 megabytes per second. For quick reference, 1000 Mbps equals 1 Gbps, which is considered gigabit.

The USB 3.0 connection type is the next step for USB (from 2.0). USB 3.0 transfer speeds are about 10x faster than previous USB 2.0 speeds. So, what does that amount to?

USB 3.0 is rated at 5 Gbps. That’s about 640 megabytes per second. 

In 2013, USB 3.1 was also released and is rated up to 10 Gbps. That’s around 1280 megabytes per second or 1.2 GB per second. This means that USB 3.1 is about as fast as a single first generation Thunderbolt channel.

It’s also worth noting that the new USB Type C connection will support USB 3.1 for a max data transfer rate of 10 Gbps.

eSATA stands for external SATA. SATA, of course, is a connection type that is used to connect an internal hard drive to a computer. So, inside your desktop or laptop is the hard drive, which in most cases, connects to the motherboard using a SATA interface.

With eSATA, an external hard drive can use that same connection type and technology to be connect to the computer. The hard drive inside a computer is quicker than a standard external hard drive (USB 2.0), so what kind of speeds does eSATA produce?

eSATA is rated at 3 Gbps and 6 Gbps.

Thunderbolt cables are the newest connection type featured on this list. Originally codenamed “Light Peak,” Thunderbolt was first a technology that was developed by Intel. For Thunderbolt’s consumer debut, Apple Inc. added the high speed interface to nearly all of their devices in the Mac lineup, making them one of the first companies to use the technology. Thunderbolt is capable of more than other connection types, but we will get to that later. What kinds of speeds does Thunderbolt produce?

Thunderbolt is rated at 10 Gbps per channel (x2). Thunderbolt 2 raises that value to 20 Gbps over a single channel. Thunderbolt 3 doubles the bandwidth again to 40 Gbps. 

Firewire, or IEEE 1394, is another connection type that was popular for a while, but has kind of gone away over the last few years. The popularity of USB 2 and USB 3 devices slowed adoption of Firewire, resulting in the slow decline of the connection. This occurred even though Firewire 400 and 800 are faster than previous USB technologies (not including 3.0).

Firewire is rated at 3 Gbps (400) and 6 Gbps (800).

Ethernet is a connection type that is used mainly for networking, so it is not designed to be super-fast. However, Ethernet cables can be used to transfer computer data too.

Ethernet is rated at 100 Mbps.

Summary

To summarize the above data, the connection types would result in the following, from fastest to slowest.

1. Thunderbolt (up to 40 Gbps)

2. USB 3.1 (10 Gbps), then USB 3.0 (5 Gbps)

3. eSATA (6 Gbps)

4. Firewire (6 Gbps)

5. Gigabit Ethernet (1 Gbps)

6. USB 2.0 (480 Mbps)

7. Ethernet (100 Mbps)

However, this analysis is not quite accurate. As mentioned earlier, in actual situations, many of these max speeds are rarely achieved. Here is a chart from Wikipedia that summarizes the specs for many connection types beyond just the ones I mentioned.

When purchasing an external device or a new computer, the main thing to consider is the version of the connection type. For example, if you are purchasing a new Retina MacBook Pro laptop, you’ll notice that it has a USB 3.0 port and a Thunderbolt 2 port.

If you hold off for a bit, Apple will probably include the newer Thunderbolt 3 connections into their latest MacBook’s, meaning you can do a lot more with those ports than before. For example, with Thunderbolt 2, you can connect up to one 4K display at 60Hz or two 4K displays at 30Hz to your computer. With Thunderbolt 3, you’ll be able to connect up to three 4K displays at 60Hz or one 5K monitor at 60Hz.

Ethernet is extremely slow and it can be used for file transfers and moving folders, but its main purpose is for local networking.

In my view, Thunderbolt and USB 3.1 (Type C) will eventually become the standard on most computers. They provide the most speed with extra features like two-way power and multi-monitor support. In addition, both technologies have already been adopted by many major PC manufactures. If you have any questions, feel free to comment. Enjoy!
