After searching around for a FireWire card I chose this one. Found that many recommend the TI chip, I think they are the ones who created this.
Was easy to install in the computer, (I have some knowledge and experience in this though.) had to change the plate to the larger size slot.
Was not sure about if it worked on Windows 7 64bit, but once I inserted the driver disc you chose the operating system you have and Windows 7 64-bit was listed in there. Recognized my Drobo Beyond Raid 4-Bay USB 2.0/FireWire 800 SATA 6GB/S Storage Array
and seems to work!
Now how do I know exactly how fast my transfer speed really is?
FYI the packaging was POOR (reason for only 4 stars), See my photos that I and uploaded here. No bubble wrap or padding, but seems to be working. Seems to be a generic card, not sure who made as I look at the packaging, But is made in CHINA! You can see the TI logo on the chip!
