USB 2 v USB 3 or 2 USB 2 or not 2 USB 3

USB 2 v USB 3 or 2 USB 2 or not 2 USB 3

To get maximum performance out of your USB peripherals make sure you plug USB 2 devices into USB 2 sockets and USB 3 devices into USB 3 sockets

For example is a waste to plug a mouse into a USB 2 socket and you can increased your USB 3 disk drive from 30M/s to 80M/s if its plugged into a USB 3 socket.

So how do you tell ?

  • USB 3 sockets are often BLUE
  • Run Device Manager and Order by Connection
  • Use a hdd case that has a power light showing you the speed (the SALCAR SATA USB 3 case power LED glows WHITE for USB2 and BLUE for USB3)
  • Manually test transfer speeds in different sockets

howto install WXP SP2 on a SATA HDD thanks to @morgancomputers

You can only install windows xp service pack 2 (wxp sp2) on a SATA HDD if your BIOS lets you change HDD mode to SATA Compatability from SATA AHCI.

If you BIOS doesnt let you do this you have have to use a windows xp service pack 3 (wxp sp3) dvd instead  which does support SATA AHCI.

After installing wxp sp2 you can then go back into the BIOS and change the HDD mode back to SATA AHCI

Many thanks to @morgancomputers tech support for explaining this all to me
