Hvordan får jeg raskere HDD til ASUS P5Q SE2?

[Oxygen 07-12]

Hovedkortet er ASUS P5Q SE2, og jeg skal kjøpe ekstern harddisk. Har hørt USB2 eller Firewire er å foretrekke for hastighet, mens kortet støtter maks USB. Er det veldig stor forskjell på USB og USB2?

Kortet ditt (Intel P45 chipset) har selvsagt USB2. Det er vel ca 10 år siden det kom.

 

Hastigheten på USB disk er omtrent 1/3 av hastigheten på en intern disk. Vet ikke så mye om Firewire, men tror ikke forskjellen er av betydning.

Hva med USB2 da?

 

Fant det nå.

Sjekka bare raskt på Komplett, så de har feil.

Når man snakker om USB så mener man high-speed USB (aka USB2). Det finnes ingen eksterndisk som bare har USB(1). 

Hvis man skal differensiere i dag så blir det USB3 vs USB. USB3 har såvidt begynnt å komme på markedet.

Er det altså liten merkbar forskjell på USB og USB2? Er Firewire på samme nivå som USB2?

What is the difference between USB 1.0 & 2.0?

 

A:

As we all may know, USB ports are on your computer so you are able to connect external devices to work with your system. Most computers today come with one or more USB ports and they're so fast and easy to use. It's easy just to plug something into a port and go. Most newer computers come with USB 2.0 ports (or even 3.0 in some cases!), but some of the older ones still have 1.0 or 1.1 (which are very similar to each other).

 

So, knowing the differences between port speeds is important to understand. The main difference between the 2.0 and the 1.0 or 1.1 is that the 2.0 USB ports aremuch faster. It's pretty much as simple as that. USB 2.0 averages a data rate of 480 Mbps (megabits per second) while USB 1.1 only hits 12 Mbps. That's about 40 times as fast! Wow!

 

Also, USB 2.0 is considered Hi-speed mode while 1.0 and 1.1 are known as full- speed USB modes. Think of it like high-speed Internet, which is just a lot faster than dial-up. It's about the same with the port speeds, so that's an easy way to look at it to keep it all straight.

 

With those basic differences covered, let's keep going to talk about how USB 2.0 and 1.1 work together. You may read all over the place (even in WorldStart's ads) that 2.0 ports are backward compatible with a 1.0 or 1.1. So, of course, 1.1 ports are forward compatible with 2.0.

 

If you have a system with USB 2.0, you will see that as your main (enhanced) port when you go into your Device Manager, but you will also see two other USB controllers listed and those are there to allow for the different compatibilities. You also need to understand that any Hi-speed USB device will convert to the full-speed operations when you use a 1.1 device in a 2.0. They will automatically default to the lower speeds.

 

Just to let you know, mixing the different port speeds is not a big problem. As long as your system and your devices are healthy, you won't run into any issues when working with the different port speeds. Just make sure you follow manufacturer guidelines and you should be good to go.
