Hello,
Just got my FASTA-6GU3 Pro today. Here is my review.
----------1st: internal SATA test:
Drive: Vertex 4 512GB (rated at 560 read / 510 write)
System: 2009 MP
Black Magic: Read: 440 - Write: 400
Aja: Read 370 - Write 330
I also tested it using a large file on a RAM disk, and the results pretty much match the Black Magic results (434R, 421W). As a boot volume it works fine, with no issues and actual real-world performance in line with the benchmarks (no surprises, no hiccups).
-----------2nd eSATA
The drives in my PM enclosure mount fine, albeit more slowly than when I used my old Sil3132 card. Sadly, when I stress test the drives (by copying files, big or small), the connection fails, the drive locks-up and ends-up dismounting disgracefully (Finder warning about improper dismounting, and Carbon Copy Cloner telling that the mounting point changed.). I verified that phenomenon 3 times before pulling the card out.
In theory, it only works with 1 PM enclusre at a time, but I only have 1 to test in any case...
-----------3rd: USB3 problems
The keyboard and mouse work flawlessly through the USB3 hub in my monitor.
On the other hand, drives in a USB3 enclosure are problematic. I only have 1 (brand new) USB3 dock to test, and it's not working well at all. (The enclosure works flawlessly on my Mac's USB2 ports.) The drives mount, but as soon as I try to test them using Black Magic or AJA, they freeze and crash. When I then try to manually erase the temporary files they create, Finder won't allow it because of a -50 error. Very frustrating. This happens when plugged directly into the card, or through a USB3 hub.
Same thing happens if I simply try to copy a largish file on the drive. Finder copy freezes to death. Strangely enough, when the drive is plugged into the hub, the copy stops, then I get an error and there isn't a death freeze...
After contacting Caldigit, all they could do was tell me to update my system and fix permissions. (I did, to no effect.) They then told me that the only dock that was compatible with their card (on a Mac) was the Voyager. That is just sad.
Clearly, this card is not a complete USB3 solution, and will only work reliably on keyboards, mice, and other very-low data transfer gismos.
