LaCie offers USB 3.0 to Mac users

The LaCie card appears to require power, too. If you're thinking of using this in an Xserve, you're SOL as far as I can tell because there's no internal method of dragging power over to this card.

You "reporters" are intellectually lazy. A major player like LaCie comes out with an announcement that they are first to the table with USB 3.0 and you basically republish their press release as news. You don't even bother to change the headline (google USB 3 os X and you will see how many of you write the same headline). Fact check much?

If you had, you would have realized that CalDigit had already released 2 USB 3 products for the Mac over a month ago (and theirs does not need their companion drive):

Great, but it doesn't work. As I discovered, LaCie locks out any USB 3.0 peripherals but their own. So yes, this driver works with any card but no, it's not a universal solution. I think their customers will be pretty mad when they discover this limitation!

Here's my post on this:

To answer the question of whether this works properly on a hackintosh, yes.. providing you're using either gigabyte or asus (usb 2.0 onboard).

My Gigabyte H55N USB3 mini-itx has usb 3 working perfectly thanks to this driver.

The LaCie card is using the SAME NEC/Renesas D720200F1 controller that Gigabyte and ASUS use.

From the picture, it looks like a tight fit in my SD card slot.

Actually, it's not LightPeak holding it back. It's Intel.

Keep in mind, all the USB3 chipsets currently available will never reach full USB3 speeds on both ports because they require PCI-E 2.0, which Intel doesn't supply on all the lanes.

So, if you want USB3 on your Mac, you can either get it now but bottlenecked, or you can wait until it can be done right.

I'd prefer to have an eSata/USB port like Dells have had for years.

Light Peak is the reason why Apple has not implemented this. Likely coming in first quarter of 2011. Significantly faster than USB 3.0.

But will it hackintosh?

Thanks Lacie. It's disappointing that Apple isn't supporting this out of the gate. For those of us that have huge photography libraries, virtual machines, etc. on external drives this may be a huge benefit.
