On a Mac Pro 5.1, do I need the 4 port card (and then run internal power to it), or can I use one of the 2 port cards (without a power connection) & then use an external powered usb?

You need to power the card. I bought two 4 port cards and powered them off the SATA power in bay 4. They work flawlessly on my 5,1 under 10.8, 10.9 and Windows 7.

I have the same MacPro. I purchased the 4 port card and did not need to run the internal power when the hard drives (or other usb devices) were externally powered. I even ran a bus powered drive off of it. Then I read that for bus powered drives it was *recommended* to have the internal power, but I haven't found a good source for that cable (please let me know if you find one). In the end, if you are externally powering, then either will work.

It's easy to connect the 4 port with the adapter cable though I can't say anything for the 2 port as I haven't installed one. Our office uses this model with no problems as of yet.

I recommend you try the 4 port USB 3.0. It requires no external power. However, charging devices through this port is not recommended. I have one and it has worked with everything I have tried in it.

If you have the new iMac (late 2012), you have USB 3.0 ports on it. You can hook up this HUB to your iMac, but you need the external power as well.

Yes, one's for power, the other for data. Whether you need both depends on your computer. If you have a recent Mac or a PC with a high-power USB port (one that can provide 1100mA at 5V rather than the standard 500mA [USB 1.1/2] or 900mA [USB 3]) then you just need the one data cable. Otherwise, use both.

Using on a Mac, you only need to use a single connector. It provides both power and data from the computer. This unit works very efficiently using only 1 USB connector!

I have it and it works fine with late 2011 MacBook Pro. There is no software to install, it is built in the Mac )S 10.6 and later, hot swaps fine,come USB power card to power external bus hard drives. This was only of four different cards I tried, this the only chip set that is support by Mac OS Fresco Logic Chipset FL1100, all the others you had install drivers and had restart computer every time to remount the cards and they constantly dropped the connection. The only drawback is the long shipping time two to four weeks.

No external power required. Only needs a USB port with enough power. Most standard USB 3 ports should be adequate.

Can I plug a thunderbolt display into it with Mac Pro early 2008 (MacPro3.1)?

Card has no effect on Mac Pro sleeping or waking from sleep. Acts just like the existing USB ports.

(Just to check the obvious), but have you tried moving the card to a different bay? Does the system have a lot of accessories or a high-power graphics card (enough that adding this card might overload the power supply -- if it's one of Apple's cards, you're a long way from this).I have used this card in a 2010 MacPro without trouble. Good Luck.

Hello Hellen,The new Apple computer might have already a slot for the SD card built in, so no need for the adaptor.If you bought already one, that will work on older MacBook Pro's like mine (circa 2007)... You can get more info about you SDXC Port on the following link:http://support.apple.com/kb/HT3553?viewlocale=en_USHave fun with your MAC...ReinaldoEDIT: that adapter used the ExpressCard Port, pretty much like PCMCIA on PC's, very old architecture... you can already read SD cards on your current port, no need for adaptor... if you want to read memory stick or any other format, you would be better of with a multi-card USB reader like:CCM® Universal SDHC SDXC TF Flash Memory Card Reader (USB 2.0) Hello Hellen,The new Apple computer might have already a slot for the SD card built in, so no need for the adaptor.If you bought already one, that will work on older MacBook Pro's like mine (circa 2007)...

Yeah, you do. I got a sata to 4 pin adapter for the power since my Mac Pro doesn't have any extra power ports. I'd check out the cal digit options. Their a little more expensive but don't require extra power. I've read mostly positive reviews of them. Again I'm on a Mac so there isn't as much support for USB 3 in older machines

My experience is that the cable native to your zip must be used or it won't work. I tried connecting to my MacBookPro with a USB cable, and it would not work because of incompatibility. So I tried with my old iMac and it worked. Apprently, this didn't require a more, updated USB cable.

What little power this card needs it draws directly from the slot. You don't even need to run a line to the power box. You shouldn't have a problem.

I run it from my Belkin thunderbolt docking station connected to my mac book pro (only way to get USB3.0 on that old sucker). Works fine, so I would assume a hub would be OK as well.
