Dear Forum Users,
I have just purchased an external WD 500GB usb 3.0 hard drive.
My motherboard does not natively support usb 3.0 so in addition I also bought a usb 3.0 controller which I connected to one of those mini PCI slots on my motherboard which gave me 2 usb 3.0 ports.
(My MB model: GIGABYTE - Motherboard - Socket 1156 - GA-P55-UD5 (rev. 1.0)
After hooking up the drive to the usb 3.0 slot I wanted to test the transfer rates by copying a 12GB folder to my new usb 3.0 external hard drive.
I was shocked at how SLOW the transfer rate actually was! On average it was only about 15-20 MB/sec which is pitiful.
Now of course I realize that the maximum transfer speed is determined by the weakest link (i.e. the slowest hard drive), but this is what I don't understand either, since both my internal drives are SATA II 3Gb/s drives (WD Caviar Blue 500GB and WD Caviar Green 1TB), so that should at the very LEAST give me about 100-150MB/s transfer rates, so how come it's SO SLOW as to give me only 15MB/s average??!
After doing the above tests I decided just for the sake of it to try and copy 2 700MB AVI files from one internal drive to the other (source drive is the WD Caviar Green 1TB and destination drive is the WD Caviar Blue 500GB). The results were equally as SHOCKING! Shockingly SLOW that is... It gave me a burst in the first few seconds of about 168MB/s, but then it settled down on about 20MB/s throughout the rest of the file transfer!
Again, this is with both drives being SATA II 3.0Gb/s drives. I think I may have stumbled upon a much bigger problem! Why are my internal drives SO SLOW???
Anyone have any ideas as to why this is happening?
Thank you very much!!!
