I recently purchased a 1Tb My passport Essential SE USB 3.0 hard drive.
When transfering files to and from the drive I get the following speeds (acording to teracopy http://www.codesector.com/teracopy.php )
read: between 40 to 70 MB/s
write: between 4 to 5 MB/s !!
I have tested the hard drive on another computer with the same results, connected the drive directly to the usb 2.0 and 3.0 ports on my computers with the same results (except slower reading when connected to the usb 2.0 port)
I own other external hard drives, a 500gb samsung 2.5'' drive and a 2Tb western digital usb elements drive. both average a 20 to 30 MB/s write speed according to teracopy
I'm using teracopy to measure the read speed because windows explorer stalls when copying files and doesn't show an accurate write or read speed.
I don't know if this can be a 'power starvation' issue, so I asked for a 'Y' cable on the support page, I couldn't find a usb 3.0 Y cable here in Chile. The cable should arrive in 2 weeks.
Do you think it can be a cable/power issue, or should I return the drive?

He's referring to a power booster cable. They're available on the WDStore, in Accessories.

I have the same external drive (My Passport SE 1TB USB 3.0) and I am facing the same problem! I purchased in US during business trip.
How can I return the drive?
