Flush USB 3.0 Expresscard Adapter

[Judicator]

The thing is, even the ExpressCard 1.0 standard should be able to connect via PCI-E 1.0, and while that won't be as fast as full USB 3.0, it should still achieve 2 Gbps, which is still faster than USB 2.0. The problem is that the ExpressCard 1.0 has both the PCI-E and USB 2.0 interconnects, and what might be happening is that whomever designed the Expresscard that you're using for some reason was stupid and didn't use the PCI-E interconnect. Or maybe you have some sort of driver issue. We don't know for sure. The point is, though, that even with Expresscard 1.0, you should be getting faster speeds than you are.

Anybody have any experience with the AKE BC618 cards? I need a 34 card not 54. One port is enough for me.

How much power do these express cards supply to external drives?

[trvelbug]

my dilemma is this- my computer has an esata port but i hate the stiff cables of esata. i was looking at getting an expresscard usb 3.0 but will it perform the same as my esata or will it be slower?
another reason im thinkin of goin usb 3 instead of esata is because i will be getting a new laptop soon that will have both esatat and usb 3. so you guys think that the usb3 expresscard would be a good stopgap till i get my usb3 laptop? or will it just be so much slower than the esata?

USB 3.0 is about the same speed as eSATA at this point. eSATA writes a bit faster, and USB 3.0 reads a bit faster from the last benchmarks I remember (same drive, connected 2 different ways).

[trvelbug]

yeah but how about the usb 3 expresscard? its half the speed of built in sata right?

Assuming that the USB 3.0 Expresscard is using the PCI-E hookup and not the USB 2.0 hookup (which would naturally limit it to USB 2.0 speeds, which is what seems to have happened to Musuta above), then the limit of a USB 3.0 Expresscard would be about 2 Gbps (in theory). This is something like half the limit of "real" USB 3.0. Depending on which level of SATA is built into your notebook, SATA limits will be either 1.5 Gbps, or 3 Gbps. Even so, unless you're using a SSD, you won't be exceeding either limit without some specialized hardware.

PP ordering 20$ hardwares and expect to do a miracle job

Expresscard to usb3 is not worth it.
With elcheapo setup it will have same speed as usb2.
and even if you buy the most expensive parts max you get half the usb3 speeds.

And whoever missed .. read again my post b4 argue over it.

ExpressCard2 will have usb3 on the bus

Oh, no, I follow your post quite well. My point is simply this; unless you're using a SSD, even half USB 3.0 speeds is more than enough. Few commerical platter drives get much past 1 Gbps. Now, if the Expresscard ends up linking up through the USB 2.0 interconnects instead, then yes, that's certainly a problem.

[trvelbug]

So what usb3 expresscard adapter do you guys recommrnd i get (54)

[Judicator]

There, I'm afraid I fail. Since I'm a lucky SOB that already has USB 3.0, I've never really thought about looking into it at all. The one that everyone else has been using seems to work alright, though (well, except for Musuta's, but I'm not sure if his is the same model as the others or not...).
