Windows 7: Transend USB 3.0 PCI Card

09 Jan 2011   #11

Windows 7 64

The plot thickens!! I got a friend to check that I had installed the card correctly and I had !! So i will send it back and get my money back.
I went o a pc shop today and bought a graphics card HIS radeon HD 5450 and the aero performance has gone down from 4.3 to 4.1 but the 3d graphics has gone up by 1.0
Also bought a different make USB 3.0 card at same time they watched me install it in the shop so I did right get home and not working computer does not reconise the card is in.

I am begining to think me and computers dont go well together I ordered some extra memory online and guess what computer wont take it work fine if take out other sticks of memory I think is because one is 667 another 5300 and the last two where 6400 which is a pain as I did the crucial scan thing and thats what came up!!

Maybe I should have stuck with my ZX81 no problems there LOL

I have finally got it to work, It has taken 3 different USB 3.0 Cards! I wish I had got the gigabyte one from the start it was a case of plug and play I have only been brave enough to put a pen drive in there at the moment so cant say what transfer speed is yet,but I will up date when I have tried this.

What I have learnt from this is if you want to add a USB 3.0 card get a Gigabyte one !

There may be something true in what you have stated.

My experience with the SYBA 2 port USB3 PCIe Card has been frustrating. Perhaps thats the one thing that had stumped me the most todate - as far as hardware is concerned.

I had seen the USB3 controller mysteriousy disappearing from the Device Manager only to reappear after the card is plugged out and replugged. This happened atleast thrice and I had to go through the exercise of opening the case.

Was it the card or the NEC 720200 driver or Windows 7 detecting the hardware on and off? To this day there is no clarity.

Next, while the pendrives get detected easily and stay put, the Seagate FreeAgent Go/GoFlex drives - USB 2 - will only play hide and seek. Sometimes they wouldn't get detected at all. I thought may be if I used a USB3 device, it wouldn't happen.That wasn't. When I plugged in my newly acquired Seagate GoFlex Ultraportable 1.5TB HDD with the proper USB3 cable/adapter, the same hide and seek game continued.

The only thing I could do now is to feed the power to the card from a different molex connector coming from the power supply. There was absolutely no rationale in doing it. It was only a desperate attempt to do what else one can possibly do and try one's luck with a prayer on the lips :). Touchwood - the problem seems to have resolved and now all my drives are recognised and stay put. Well - for how long? I am keeping my fingers crossed and hoping for the best.

I was even contemplating buying a Transcend USB 3 card which is available here itself - I bought the SYBA Card from ebay, USA - but after reading your post have given up any such thoughts. Thank you.

The transend card I have no idea what the drivers are for that, The 2nd card Novatech) Novatech USB 3.0 PCIe Controller Card 2 Port
I think the novatech card had nec drivers I called up the company and they have had a few problems with these cards and drivers.

The gigabyte card was so easy card got reconised staright away even with me forgeting to plug the power into the card The only thing I did different I used another power cable! As you know from my first post I am no computer expert, Just my advice the gigbyte card seems to work as it should where the other cards failed!

Transfer speeds USB3 vs USB2

Sorry, I missed the above post for 2 weeks.

1. SYBA 2 port USB3 PCIe expansion card with NEC UPD 720200 chip
2. Seagate GoFlex Ultraportable 1.5TB external HDD - bare drive without any adapter/cable
3. GoFlex USB3 adapter/cable (USB3)
4. GoFlex USB2 adapter/cable (USB2)

1. When the HDD is coupled with the USB3 adapter/cable or USB2 adapter/cable and connected to the USB2 port,the transfer speed remains the same - 26.4MB/sec (screenshots 3 and 4)

2. When the HDD is coupled with USB2 adapter/cable and connected to the USB3 port, there is almost a 50% increase in speed - 39MB/second (screenshot 2)

3. When the HDD is coupled with the USB3 adapter/cable and connected to USB3 port, there is almost 330% increase in speed compared to the USB2 port connection - 87.1MB/sec. (screenshot 1)

This gives a general idea as to what one can expect with these combinations. Absolute values can be different for different brand HDDs.

(Keeping all conditions same, I have noted the transfer speeds in each instance after 50% of the file is copied - in this case 9.2 GB)

@ ian986, your screenshot seems to indicate that the WD passport is only performing as a USB2 device. Is it a USB3 device and did it come with a USB3 cable?

^ that looks good.:) I presume that transfer speed may be a bit lower when copying a large number of small files than when copying one single large file, as I had done. (Not sure though, though I know both these are done in benchmarking. But from an ordinary user-perspective these differences shouldn't matter. It is enough if we know that as a USB3 device, we are getting good transfer speeds when compared to USB2)
