How to increase the performance of external hard drives?

Updated on: 2012-04-04 || Source: computeronlinetips.com

Today, external hard drives are most commonly used storage devices in any office environment. External hard drives use high speed USB 2.0(data transfer rate 480 mbps) and FireWire (date transfer rate 800 Mbps) interface for data transfer with system. These external drives are ideal solution for data transfer from one location to another location and for backup of your critical data.

The data transfer rate of external hard disk is very low as compare to internal hard disk but using windows XP and windows Vista, you can increase the performance of external hard drives. You can enable the write caching to increase the performance of external hard drives. By default write caching is disabled in all windows versions, because removable devices could not lose data if you unplug them so quickly. But when you enabled the write caching options then you should disconnect the removable drive in proper way.

 

Perform the following steps to enable this feature in windows Vista: 

  • To active this feature, you will need to be logged into your computer with administrative rights.

  • First click on Start button and go to Computer, right click on Computer and select Mange.

  • Here on the side menu click on Device Manager, a small windows dialog box will appear with the title "Device Manager".

  • Now expand the "Disk Drives" entry and locate the external hard disk.

  •  

 

  • Right click on disk and open the "Properties" option.

  •   

  • Another windows dialog box will appear with title "External Drive USB Device Properties". 

  • Under the "Policies" tab, select the check box "Optimize for performance".

 

 

Next select the both check boxes "Enable write caching on the disk" and "Enable advanced performance ".

 

Press OK button to save all these setting.
