Yes, WD stands for Western Digital. No, I do not think AC power makes the drive any faster. The drive itself is rated at a certain speed. However, USB isn't always enough power to run external drives, some computers might send enough power over USB, and others might not, so many manufacturers will add AC power to power devices. In this case, the device is not designed to take power over USB, and therefore must be plugged in to a wall outlet.
Sorry, there was a problem. Please try again later.Yes, WD stands for Western Digital. Power is power, no matter the source. What controlls speed is USB 2.0 vs. 3.0 connections/cables, how quick the discs spin, and how much buffer storage of drive/computer. I personally though prefer to see my power coming frmo an AC source ... I don't like the current drawing so much power from my expensive tower while also trying to pass data along the same cable.
Sorry, there was a problem. Please try again later.Yes WD Stands for Western Digital. AC powered vs USB could be an indicator a faster spinning drive, but does not necessarily translate into faster transfer speeds.
Sorry, there was a problem. Please try again later.WD stands for Western Digital. As far as data transfer rates, the speed of a hard drive is not determined by the power source. It is the speed of the USB connection that is the limiting factor, plus the technology used for data storage. A flash USB drive will have a different data rate than an external USB hard drive powered by AC, but the difference is in how the data is stored, not how the device is powered.
Sorry, there was a problem. Please try again later.Yes to the first, and second question, they are not correlated. Externally powered hard drives are usually larger capacity for the cost because they use larger (3.5 inch) hard drives (cheaper). Speed is not related to the power adapter or size of hard drive.
Sorry, there was a problem. Please try again later.From my experience, I would say yes....not a very noticeable difference though!
Sorry, there was a problem. Please try again later.WD does stand for Western Digital. I don't think the A/C powered hard drive makes a difference in the copy speed. I did notice that it copied about 4 to 6 times faster on my new computer than it did on my old one. Probably because my new computer could read and write faster with its i7 Core and more memory.

Sorry, there was a problem. Please try again later.Not necessarily. The speed comes from the type of connection. i.e. USB 2.0 or USB 3.0. This Hard Drive has USB 3.0. Fast enough for me.
Sorry, there was a problem. Please try again later.Yes WD stands for Western Digital. I don't notice the difference in speeds from AC powered to USB. I think it depends on the amount of files you are transferring and the size type the files are.
