    I bought a 300GB Transcend about 4 years ago, It works excellently, the back up button is unique, the fact that it has thick plastic around it makes it durable. I once bought another brand which fell and I lost data.
    I have never had any issues the Transcend brand. it. My latest purchase is from the firsthand experience with the older one. I will recommend transcend to anyone any day.

    HASH(0x92234fe4) out of 5 stars Transcend StoreJet Military-Grade Shock Resistance 750GB portable HDD 15 April 2011
    By Kirk-RS - Published on

    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 will probably not be trying that for at least part of the warranty period, but it is comforting to know that I can get the anti-shock benefits of this product with a larger drive. It appears that there is still work to be done on the 1Tb+ 2.5in drives until they become genuinely reliable, so waiting awhile seems a good bet.

    UPDATE: One other possible weak point is the USB 3.0 aka SuperSpeed USB cable. It appears to be standard -- that is, it is not proprietary to the drive. However, these cables are still hard to come by, and they are costly. Best deal I could find online is about $20 for a very short cable. That's 20% of the cost of the drive! I imagine price will fall and availability will rise over the next year or so. In the meantime, it will be important to treat the cable very gently. It is by far the most vulnerable part of the package.

    Just popping into say a big +1 for this drive. Another satisfied customer.

    Great price, great size, great feel, great speed. Works great with mac and linux so far. I have carved it into 3 partitions for different uses and its working great! Can not comment on longevity of course, but feels like a great purchase so far.

    HASH(0x910e1b40) out of 5 stars After four months product no linger works! 7 April 2013
    By Harold - Published on
    Verified Purchase
    Was using this drive to back up a client project and had it neatly tucked away. 4 months later I go to use that backup and device no longer works. It powers up and you can here the disk spinning but no communication from the usb bus to computer. I needed the files off of the hdd so I filled a tech support request on 2013-03-12 and till this date 2013-04-6 I have not had a response nor any indication that Transcend cares to contact me about my product waranty and support. DO NOT, I REPEAT DO NOT BUY TRANSCEND PRODUCTS AS THEY HAVE ZERO CUSTOMER SUPPORT! If anyone can enlighten me on how to get a replacement or even get a response fro Transcend please let me know. Product was great while it worked....sadly my experience has been marred by rubbish support.

    HASH(0x920ef42c) out of 5 stars Great External Drive 3 Oct. 2012
    By Steve Johannesson - Published on
    Verified Purchase
    I had previously purchased a similar 360 gig 2.0 USB storejet several years ago, and have never had any issues with it. My wife needed storage for all her pics, so I gave her that one, and ordered this 3.0 750 gig for myself, it's every bit as good as my previous unit, just faster, and more storage capacity. I can't recommend the storejet enough for an external drive! I've had other more "name recognized" external drives, that ended up being poorly designed, or just flat out died on me after a short period of time. Not so with the's met and exceeded all my expectations for an external storage device.

    HASH(0x920ef5dc) out of 5 stars Transcend for iMac Time Machine Backup 18 Dec. 2012
    By Michael - Published on
    Verified Purchase
    The Transcend has worked very well with our iMac's Time Machine backup software. We had to allow the iMac programming to clear the files that came pre-loaded on the Transcend, but we simply transferred those files to the iMac's hard drive before allowing them to be erased.
