Easy to use and quick install.
George Gooch
The casing is designed to give you a good grip and absorb shock so it won't slip, and in case it does, you have protection inside and out to keep your drive safe.

Great to know my data is safely backed up on a tough external drive.

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.

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.

Massively disappointed.

This drive crashed the first time I tried a back up. It kept saying I had ejected the disk improperly when I wasn't anywhere near the computer and drive at all.

It was the technical support that really was annoying. The technical support literally said:
it could be hardware, software or the cable or my computer. I sent them the crash logs and the disk utility results.
They requested a step by step accounting of what I did and to try another cable. I sent the step by step info to them.
I tried another cable. (Which is a big deal since it is a special cable that utilizes two USB ports simultaneously-not something people have laying around) I have mutliple other hard drives and computers-i just liked that idea that this was tough since I carry them around. I haven't had this problem before. I asked how could I tell if it was a software or hardware problem. I asked if this was a problem they had heard of happening with Macs.

They didn't answer that question. Instead, they suggested that I send them a step by step accounting of what I did. Uh, did that already and it apparently was irrelevant. And I was just following the quick start directions so that was what I did.

It might be that I got a bad drive and I don't want to judge the product by one bad drive but the technical service?

The manufacturer commented on this review(What's this?)
Dear J. Graham,

Sorry to hear about the external HDD problem, and the inconvenience caused to you.

To provide a better service, please provide the following information:
1. We would like to know if you try to plug the external HDD to another Mac computer, and if you get the same error?
2. Do the USB ports from your Mac computer work with other USB devices?
3. If you don't have any problem with USB ports and you try to plug the drive in other computers, so we can replace the drive since the external HDD is under warranty. Please call us to this number 714-279-1863, so we can assist you with the return.

Best regards
Captain Transcend.

I shoot a lot of HD video footage on digital still cameras such as my GoPro HD Hero and Canon SX20IS which both use 32GB SDHC memory cards for storage. When I'm on the road its easy to fill a memory card with 2.5 hours of HD video long before my shoot is over. With this hard drive and my laptop nearby I can drop the memory card into a card reader connected to my laptop and dump the contents of the card to the Transcend HD while I continue to shoot on the second memory card. This keeps my smaller computer HD from filling up. And makes it easy to transfer the video back to my desktop machine later for editing. While I am around the house I use a wall plug USB power supply to connect the power cable to for powering the hard drive and keep the computer USB electrical load to a minimum.

All the advertised features of this drive are spot on. So there is no need to repeat what others have touted.

There are a few things to mention which might be helpful. I run Mac computers and this hard drive is very Mac-compatible. Just use Disk Utility to format the drive as OS extended or OS extended Journaled. And you are rigged and ready to store. The running light indicates the drive is spinning. After about 10 minutes of inactivity my drive goes to sleep and spins down so that there is minimal power usage which is especially important if you have it connected to your laptop on battery power. NOTE: Unplugging the USB power cable from the hard drive WILL NOT shut it down if the USB 2.0/3.0 cable is still connected. It appears that power will also flow through the communication data cable if you pull the power plug first. Maybe not such a good idea since they provide two cables for a reason. Plug in the Power Cable first, then the data cable.
