Can you attach two (2) External Hard Disks with the express card and can transfer data from one to another with the mentioned speed of 5GB/s?

No hard-drive actually transfers at 5GB/s, nor does any USB 3.0 port. These are just theoretical maximums. What you should expect is around 60MB/s transfer, maybe up to 80MB/s. This device also doesn't have the potential for 5GB/s; It's not attached to a PCIe in the laptop that can do it even under theoretical situations. It IS faster than 2.0, but don't expect SATA III speeds. In addition, this card does not independently provide enough electricity to run 2 external hard drives, which is why it has that little port in the center. If you're running two "high drain" devices from them, you plug that cord into one of your USB 2.0 ports and it'll provide extra power. Hope this helps, but if you're looking for super high speeds like 5GB/s, then you need to read up on "theoretical versus actual USB 3.0 speeds".

I believe you can do it as it has two usb ports. I've not tried it myself. Not sure about the speed either.

Yes, but that is the max speed, average is about 3 to 3.5, on my old laptop anyway. I got a new one for Christmas and it has no place to plug in this card so I gave it to my son (along with the old laptop), he is in CA now or I would test it again.

They do!5400 rpm drive to 5400rpm drive I get 65-75 Mb/s minimum using both ports.

Yes I'm running two hard drives. If you want more it would have to be an external.

Yes you definitely could. However, if you were to plug it into a usb 2.0 port, it will give you usb 2.0 transfer speeds.

Assuming you have the letters available for the drives and each drive is powered, you could but the transfer speed will be horrible. I don't think I've pushed harder than 5 drives hooked up

I purchased this card just to test my new Kingston USB3 thumb drives on a Dell D830 Express (smaller 34mm PCMCIA card slot, and required an adapter to hold it in correctly). Loaded under Win7 and Win8. It functions, once you get the drivers loaded.. but certainly not at 5gb/s. I get just slightly better than USB2 file copies. For my setup using a USB2 thumb drive, I can get 27-30mb/s, and with a USB3 thumb drive I might get 35/40 mb/s. To get 5GB/s you would need (I believe)a USB3 Super Speed flash drive and an express card bus faster than the one in this Dell D830. The one in my Dell D830 I believe... is 16 bit and PCMCIA version 1.0. PCMCIA and express does come in 32 bit flavored slots and up to version 2.0. These might do USB3 super speed, but check the PCMCIA wiki. PCMCIA is dead pretty much after about 2009, i.e. no newer laptops are using it. Which is a shame... IMHO.. and YMMV Drivers for this card and other USB3 Express cards are well.. difficult to be certain of and can be OS dependent. If you know the chip vendor, i.e. like Renesas, then you will typically be better off loading any USB3 card. In my experience anyway. Again.. YMMV

The short answer is no. Your speed will most definitely be limited by the slow 5400rpm disk. It will not take full advantage of the Thunderbolt or USB 3.0 bandwidth. I'll be getting a Thunderbolt drive with SSD.

Thanks Mr. Brown for your fast Reply!I am going to try to format the Card to exFAT...Do you know if the exFAT could handle large 6 or 12 GB Files?

Depends on the backup software, but generally yes. You connect them not directly, but by attaching the drive to a compatible router on your network. Some routers have USB jacks for hard drives. Do a search on "attach hard drive to router" and you'll get information. This is called "network attached storage" (NAS for short), by the way.

I carried out a survey of Express Cards about a year ago and as a result purchased one with two USB 3.0 ports and the other with two eSATA ports and am very pleased with both but I never came across an Express Card with video capabilities. I believe EVGA sold and may still sell an USB 2.0 video adaptor so if you have a laptop with a dodgy video card and don't use it for gaming this may work for you.

Yes for you to get the USB 3 speed out of the 2 USB 3 ports, as it has already been mentioned maybe you could find a cable to convert 3 to 2 but you won't get the 3 speed, which is nice.

Yes... Since its not a RAID enclosure, you can copy from one drive to the other from within. You get normal SATA 3G speeds when doing this.

Yes, there is also an SD expansion slot that may be used to transfer files. I bought two of these for my kids and thus far I am very pleased. So much in fact that I'm considering buying one for myself as a back up.

No, USB to express card adapters only support USB based express cards not pcie based ones

You can use the cable that came with the drive (actually, you have to since USB 3.0 has one different end). It will automatically transfer data at 2.0 speeds.

I initially used the card as formatted (ExFat) but found that the data transfer speed was slower than advertised. I reformatted Mac OS Extended and found it to be much quicker.

Yes you can. In fact it's incredibly easy. Here's a video showing you how. http://www.youtube.com/watch?v=uyUfs788cJk Just as an fyi, the max is 2gbs.
