CalDigit has two different cards, one is a pure 2-port USB3 card, the other one is USB3 and eSATA 6G card. They both work great.Hi
Can anyone advise me on a USB3.0 card for my 2009 Mac Pro (pref 4 port).
I have a mixture of various drives so it would need to be able to read them all as I've heard some cards will only read data from certain manufacturers.
Caldigit claims it is the nature of PCI-E USB 3 cards, at least for them. I use it for an external SSD dock, so I just ignore the error and reseat the drive. As long as I get these sustained write speeds for HD video, I'm happy. It is sort of a PITA though, actually just a nuisance, but keeping a Mac Pro updated is full of headaches no matter what.it works but ... if you connect an external HDD via USB3 and the Mac is going into into sleep mode.
What happens shortly after system wakes ?
I get the "device improperly dismounted error".
Thats crap (unfortunately)
