My laptop is Dell D630, came with USB 2.0, and the speed of the USB 2.0 almost drive me crazy especially copying some HD movies. I think most of us who use the old USB 2.0 will have the same feeling.

So now USB 3.0 is coming! I would like to know what will you do to add USB 3.0 ports to your old laptops(don't tell me to buy a new laptop with the USB 3.0 ports, I will use it for another one or two years).

Well, you can wait or try now, I won't advise you further. Don't have time to look at those links either, going on Vacay.

I use both PCMCIA and Xpresscard (Bytecc RAID and Vantec) and get full speed, much faster than Firewire800 and especially USB.

BTW, you know most HDDs are limited to 60MB/s, look at the interface speeds to see max, but magnetic disks usually top out @ 60-80MB/s you need an SSD (and a GOOD one) for max speeds. Those links are likely drive limited.

BTW 50+MB/s is higher than USB already (which is theoretical 480Mb/s but practical 400 and less).

Base on the description of D630 from Dell documentation, the PCMCIA is via USB interface, that means if you use a PCMCIA card to eSATA/USB3.0, the maximum speed is limited to 480Mb/s.

BTW, if there is USB3.0, I will abandon eSATA, because new power from eSATA interface.

OK, D630 has a dismountable DVD Rom, I think we may use that interface, however, I don't know what's the maximum speed of that interface.

Thanks for your help! I will go to buy a PCMCIA to eSATA card and try it when I am at office next Monday. I will update the result here.

BTW, my 3.5'' hard drive has a speed at 66MB/s when I connnect it to the motherboad of the desktop. If I can get a speed aroud 50MB/s through eSATA, that will be acceptable.
