While this latest PCIX-USB3 board would work with my MomentusXT in a USB 3 caddy, it would not work with a NexStar SATA to USB 3 adapter. When you plug in a drive, the hard drive would momentarily appear, then disappear, then popup with a 'Format this drive' requester. I knew something was wrong with this behavior as the drive is formatted and works perfectly on another system.
I took the card out and returned it to Fry's and looked to see what other cards they had available. Turns out that there are at least two versions of the Sabrent PCIX-USB3 board at Fry's (each in different packaging). One is printed on the board with the words 'NEC Electronics Corporation'. The non-working board appears to be generic without any manufacturer labels. The non-working 'generic' board is a lighter shade of green and has a Molex power plug that points towards the front of the case. The functioning board that's labeled 'NEC Electronics Corporation' has the power plug that points upward towards the side/top of the case and has a darker green-ish/blue color. This board also has two LEDs right near the USB ports. Again, the packaging is also different.
I'm not sure which one is the newer board, but it's clear that the 'generic' board may not work properly. The other issue with the generic board was that the Molex connector was loose on the board. So, when you plug in power to the board, it feels like you're going to break this connector off.Read more ›
"Requires 15-pin SATA Power Connector"
The package states
"4-pin power connector for extra power." My power supply has no old-style connectors. No go there.
2. The package states "driver CD." The Amazon description states "Drivers CD."
Must have gotten left out somehow. Granted, I have the Internet and can use Google, but should I have to after paying 30 bucks for something that...
3. Does not actually appear to support a USB 3.0 drive.
My drive disappears when it is plugged into the card but pops right back up when attached to a USB 2.0 port. It supports a USB 2.0 drive just fine.
I'm pretty stewed. Back to Amazon to try again.
As for the speed: I only tested it with a portable harddrive (WD My Passport Essential SE 750 GB), and saw about twice the transfer rate using USB 3.0 than USB 2.0 (about 60 MB/sec versus about 30 MB/sec). Not a very scientific test, but it might give you some indication.
My only small complaint: I could not get the card to sit straight in its slot. Both USB slots are accessible, so it is more an aesthetical problem.
I would suggest you to go find a different 3.0 usb card of a similar price.
I don't recommend it as it is worthless.
