Adding USB 3.0 card to desktop PC

  Gummomarx 13:21 20 Feb 2018

I want to add USB 3.0 capability to my desktop PC. How will I know which card to buy in terms of compatibility with the machine (HP Workstation xw8400 Base Unit)?

I am just wondering if USB 3 is a step too far for Windows XP

Have to agree with wee eddie it may be a step to far for an XP computer.

Reading Fruit Bat /\0/\ click here it does say compatible with XP but it also says this.

Notice: Windows XP and Vista Users Please Note: Due to OS limitations, the real transfer speed after installation of the respective drivers will be located between the level of USB 2.0 and 3.0.

So I suppose is it worth the expense probably not.

But if Fruit Bat /\0/\ says that it will work it probably will.

I see no reason why it shouldn't work. These are the results SanDisk Extreme 64 GB USB Flash Drive USB 3.0 in XP src and W7 src

Thanks very much for your kind considerations - particularly indebted to *Fruit Bat /\0/*.

PS: I've been running Win 7 successfully on the PC.

I make it your computer is about 12 years old so hope it works ok for you.

It still flies along, thanks.

One more thing - I have several USB extension cables - will they inhibit the expected USB 3.0 speed levels? Or, do I need to buy USB 3.0 extensions?
