Latitude E6x20 USB 3.0 Module

Hi,

I've got some questions for the (few?) people that bought a USB 3.0 Module for their Latitude E6320/E6420/E6520:

How long have you used it?
Have you had any problems with it (stability, speed, freezes, drivers, etc.)?


For more information about what I mean, see:

Thanks!


P.S.: For those interested in buying it: A Dell Germany sales representative told me over the phone that it costs 40 EUR (value added tax included). In the US it costs 50 USD according to Dell's website.

 

I can't comment about problems with USB 3.0, but I had considered getting it on an E6320 until it was pointed out that one cannot use it to run a Win 7 backup/restore CD (to restore a system disk image) since the USB 3.0 drivers are not loaded onto the restore CD when it's made.

Until USB 3.0 is native on the chipset (like eSata), it will not be useful to me. Also, eSata is slightly faster.

Yeah, USB 3.0 in its current form is not exactly ideal, but at least it should be useful during normal Windows use . Besides, since USB 3.0 is backward compatible, one can always resort to the motherboard's USB 2.0 ports if the USB 3.0 ports are unavailable (at USB 2.0 speed, of course ).

I'm interested in it mainly for external drives (HDD, flash drives, Blu Ray, etc.) and other high bandwidth peripherals. Currently, I'm not planning to buy any USB 3.0 devices in the near future, so it's more of a future proofing thing.

I see myself in the future looking at the USB 2.0/eSATA and USB 3.0 versions of a device and asking myself "Should I buy the compatible, but more expensive USB 3.0 version, even though my current PC has USB 2.0 only and wouldn't benefit from SuperSpeed, but my next PC probably will?"

Kudos to Intel for focusing on bringing Thunderbolt to the Mac (and only the Mac, at least for now) and leaving us PC users with USB 2.0.
