Just thought I would ask the community a question before I make any hasty decisions. I have a Lenovo Y510 laptop ... it's coming up on 2 years old and is not as nearly as flash as it used to be, at least compared to the lappys my friends are now purchasing. I have no reason at all to buy a new laptop but I really want to be able to use USB 3.0. The only way I see this happening is with something like this: http://www.newegg.com/Product/Product.a … -_-Product
Of course they don't advertise linux support, but I was wondering what IS support for these types of devices like on linux?

is usb 3.0 already a standard? if its not yet complete. just wait it a while. you will end up with broken hardware

The Linux kernel has had USB3 support for nearly a full year now. Hardware is just coming out however, and is relatively uncommon in the wild

the support, as far as i know, is for the drafts.. its not final. anyway, software can always be patched, its not the same with hardware. i do recall some time in the past, some usb pci 2.0 extension cards didnt work correctly.
anyway. i still believe its too soon to be buying usb 3.0 hardware.

It is early...but if you're buying an integrated system like a laptop that cannot be upgraded, better to jump in now as you cannot easily swap in a PCi card.

thanks for all your replies guys, I'll take your advice and wait a while. Have any of you had problems with getting express cards recognized on ur arch systems? That is if you have a laptop running arch (or any other distro for that matter)

There's a big catch-regardless of compatibility.
USB3.0 is designed for throughput of 5 Gigabit/second on each port. PC ExpressCard 1.x only supports 2.5 Gigabit/second. Even PC ExpressCard 2.0 (recently unveiled if memory serves), and a full PCi rail on an ATX mainboard only support a max of 5Gigabit/second, i.e. only ONE USB3 port at full bandwidth. You see the problem, no?
The lesson here is that USB3.0 as a PC card on a laptop is only worth the trouble if you have a PCExpress 2.0 slot, and even then it only gives you 1 full speed port and nothing more.
Of course, I can't think of ANY peripheral device that can even take advantage of 5 Gigabit/second (or 600+Megabyte/second) of throughput. No peripheral device to my knowledge out there can feed that much data through a bus at that speed today.

Someone will do USB3 webcams with 2 Gazillion megapixels

haha! alright thanks heaps again everybody... I'll probably not even buy the expansion card unless I need more ports.
