I bought this usb drive to use with my digital photos. I work on a laptop and, because I take raw digital images, I wanted someplace to store my photos off of my machine. The logical solution was, of course, an external usb drive but, since my cat loves to jump on my lap or on the sofa when I am working, I worried about the possible damage to the drive from sudden movements. This was my solution to that problem. After reading some of the reviews I assumed that I would need two cables, one for data and one for power, and that there would be two usb connections on the drive. So, first off, let me be clear about what is and what is not needed to use this drive.

This drive itself has only a single usb 3.0 connection. The cable that comes with the drive is a Y cable with two connectors for the usb connections on the computer, but only one connection on the drive itself. As I said, the Y cable has two computer connections, but the wires are not the same. The thicker one is for data and the thinner one for power. So, to check the drive, I connected the usb connection on the drive and then first connected the data cable to the computer. To my surprise the drive spun up and my laptop identified it as a Transcend usb drive even though I had not, at this point, connected the power cable. Since I was surprised I did some checking and found out that the drive worked properly without the power connection to the computer being plugged in at all. I then checked the drive with the Y cable with both connections and the drive worked properly. I then tried the drive with a spare usb 3.0 cable I had for some other usb drives and the drive also worked properly.

Be sure to check the different prices on different sizes. At the time of writing the 1TB drive was only $10 more than the 500GB drive so worth the upgrade.

If you're a Mac user setting this hard drive up with your computer is super easy follow these steps.

1. Plug in the hard drive
2. Open up disk utility found in your applications folder inside the utilities folder
3. Next select the newly plugged in a hard drive and on the right-hand side you should see partition click on that.
4. Then inside that screen on the partition layout drop-down choose how many partitions you'd like to set up. I generally go with one partition and just use folders to organize my files.
5. Then on the right-hand side you can name the partitions and select the format. If you want your hard drive to work with your Mac for doing Time Machine backups (which I highly recommend) choose Mac OS Extended. Sometimes it's good to make two partitions and one using "MS-DOS fat" if you might be transferring files to and from a Windows machine (I do this with my friends as many of them run Windows so I have a little partition for giving them video files and the like). The reason is Windows machines and Macs can read and write to the "MS-DOS fat" format but your files will need to be under 4 GB each as that's the maximum file size it can hold.
6. Then click apply and your Mac will create all the partitions you wanted and you're good to go.

Transcend 750 GB 2.5-Inch USB 3.0 Military-Grade Shock Resistance Portable External Hard Drive for Mac and PC TS750GSJ25M3

I have owned and used a number of portable USB 2.5in external hard drives over the years. This one looks like the best of the bunch, out of the box. It is by far the most solidly constructed, whisper quiet, and hardly gets luke-warm to the touch.

I had some concerns about USB 3.0 because it requires a separate power cable to give the drive enough juice to take advantage of the speed. I don't yet have a computer with USB 3.0, so I did not want to have to use the power cable for USB 2.0 transfers. Sure enough, the drive worked just fine on my old Dell E1505 laptop with just the data cable attached. The surprise came with my ASUS netbook. I often have to use a power cable to keep an external HDD connected. The Transcend works first time, every time, even when the netbook is on battery. In my experience, this is outstanding!

My only issue thus far: I can't change the drive name from "Local Disk" to something more distinctive. I have not explored the "Elite" support software, so maybe the answer lies somewhere in there. If not, it will be part of my next contact with Transcend tech support. (UPDATE: No joy so far; I emailed Tech Support about this)

Before purchasing, I called Transcend's branch in Maryland, and got through to a human being on the second try. Tech support assured me that if I was willing to violate the 3-year warranty, I could insert a 2.5in 1Tb or even a 1.5Tb drive in the enclosure, and it should recognise the drive.
