Although this article is a bit noisy as continuously ventilated, it is unbeatable in price / amount of storage available. And even if it displays 2.72 TB instead of 3TB announced due to system files necessary for its functioning. I already had a 2.5 "1 TB, which fully satisfied me for a year, but nearly full, because of my GoPro videos. This new hard drive (Ref: STBV3000200 3TB) allowed me to do a mix for a more than reasonable price !! 3 connected he posted in USB transfer speeds of up to 96.6 MB / s to 83.8 MB / second for the lowest I've raised, copy copy / paste of my pictures files (Raw or Tiff to some) GoPro Full HD video. it took me from about 1H to copy 250GB of data and exactly two hours and twenty minutes to "dump" entirely my hard drive 1TB copy on it. Note that my PC with only one USB output 3 both drives are connected to it via a USB 3 "Advance" Hub that I bought at the same time almost my first Seagate drive 2.5 "1TB (Ref: STBX1000201 1 TB). These two articles fully satisfied me. Note that I modified my review because I was mixed me in my notes about my copy time! To the sound of permanent ventilation that can generate a resonance depending on the medium on which is placed the hard drive (camping table for me!) I solved the problem with an envelope "bubble" below, plus a piece of strong cardboard on top to avoid blocking the air vents. This done, the disc is downright forget. Note that using Windows 7 64bit, my two Seagate hard drives stop and start all alone at each stop or start Windows without any intervention. So for those who demand stops buttons, those are useless. One final note about the USB cable length, perfectly sufficient about 1.10 meters, and the AC adapter (the disk is not self-powered saw its size and permanent ventilation) comes with appropriately two sets of interchangeable pins and a protective cover for those traveling with their drive. A game "round" homegrown standards us, more a game with flat pins, like England and others ... Very good article and very good seller, I recommend both! Thank you to all and good shopping at Amazon ;-)
