Discussion Overview

The discussion revolves around the possibility of combining two hard drives into one connection to save USB inputs on a PC. Participants explore various solutions and alternatives, including the use of USB hubs, PCI cards, and powered enclosures, while addressing concerns about power supply and performance.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant suggests using a USB hub to combine the connections, comparing it to a network router that can connect multiple devices to one port.
  • Another participant emphasizes the importance of using a powered USB hub to ensure sufficient power supply to the hard drives, noting that splitting power can lead to performance issues.
  • A participant mentions that some hard drives may require a second USB connection for power, and suggests using AC to USB power transformers for those connections.
  • Another option proposed is to use a USB PCI card instead of a hub to increase the number of available USB ports.
  • Concerns are raised about the potential slowdown of hard drives when using a hub, especially with USB 2.0 connections.
  • One participant expresses dissatisfaction with using a hub, citing issues with reliability and the need to connect directly to the PC at times.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best solution, as multiple competing views are presented regarding the use of hubs, PCI cards, and power supply considerations.

Contextual Notes

Some participants mention the need for external power supplies and the implications of power distribution among multiple devices, but there is no resolution on the effectiveness of the proposed solutions.

Hi,

I have two hard drives hooking up to my PC and they used up my 4 USB inputs. I am thinking of if we can combine the two to be one, so that we can save two USB inputs. Anyone can help? Thanks

The extra USB cables are needed to supply extra current to the HDDs in order to reach maximum read/write speeds.

As stated by russ_watters, the best option would be to use a USB hub - it could be compared to a network router - which basically joins anything from two to eight or more USB devices into maybe one USB port.

Personally, if you do choose to go down the route of using a hub, I would recommend one with an external power supply since you are effectively splitting the ~5V and ~500mA between many more devices than normal (I can't remember if this is the current specification or not) which may cause them to run slow / not at all.

Search eBay or Google for more information, alternatively another user or myself can provide links if necessary.

First of all, I would like to thanks to all.
Yes, I am using an USB hub, but as I said I don't like this way. Moreover, sometimes they don't work with the Hub and I have to hook up directly to my PC. I thought of the power inefficiency but it is not right as my hub has an external power supply.
 
You could get a usb PCI card instead of the hub. Maybe that would solve it.
 
The only way you're going to be able to get rid of the second USB connections is to get new enclosures that are powered by wall power rather than drawing from USB power.
 
If you're certain that the 2nd connection on each drive is for power only (which seems like a reasonable assumption) you could get AC to USB power transformers like http://www.dealextreme.com/details.dx/sku.4837" for those connections.

Probelm with a hub, even with USB 2, is that it will slow it down (more so than it already is as a HD being run through a USB)
