USB 3.0 Experiment

Had tried a couple of USB 3.0 cards and devices recently, tested with Kingston Value SSD 128GB

Subjects:

1. SYBA USB 3.0 PCI-E 1x adaptor

2. Transcend USB 3.0 PCI-E 1x adaptor

3. UNITEK ExpressCard/34 USB 3.0 adaptor

4. UNITEK 2.5″ SATA to USB 3.0 case

5. SNT 2.5″ SATA to USB 3.0 case

6. Seagate GoFlex SATA USB 3.0 adaptor

Results:

#1 – Power supply to the devices are weak in the first try, exchanged and still suffer from the same weak supply problem (supplier claimed that they have fixed the problem by adjusting the components)

#2 – Works normally, and it is the one inside my PC

#3 – Must use external power supply if the device is not self-powered, similar cases for the other brands, prepare to use power adaptor cables to supply extra juice to the card for ExpressCard/34 USB 3.0 adaptors

#4 – Supplied cable is a bit too long, have to be plugged to the card directly (not working when there was an USB 3.0 extension cable), the craftsmanship of the PCB is not in high quality, it uses USB 3.0 B to A  type USB 3.0 adaptor cable, even with enough power, there are intermittent disconnects and reconnects once in a while

#5 – Similar situation as #4, but it uses A type USB 3.0 port and A to A type USB 3.0 adaptor cable (NOTE: do not plug a USB 2.0 cable to the rear port of the HDD case)

#6 – Works normally with or without an USB 3.0 extension cable, perfectly stable

Transcend USB 3.0 PCI-E 1x adaptor & Seagate GoFlex SATA USB 3.0 adaptor are the only ones working perfectly so far.
