Document: Toshiba Canvio 1.0 TB USB 3.0 Portable Hard Drive - HDTC610XK3B1 (Black) is what I purchased. I've always liked the Toshiba portables because they are small, have low power consumption and just work with no BS involved. USB 3.0 is a new standard in USB speed, but is backward compatible with the USB 2.0 standard. So if you have USB 3.0 ports on your computer then you can enjoy the speed of the USB 3.0 standard.
Toshiba Canvio 1.0 TB USB 3.0 Portable Hard Drive - HDTC610XK3B1 (Black)Great solid drives without any junkware installed.I used to be a Western Digital Fan, but after WD started rolling out Smartware & Virtual CD to their external disk without giving the user any option, I started looking into other brands. First I bought a Seagate, big mistake. Clicking noise & failed disk in less than two months. Then I looked at Toshiba & my 1st one was a 640 GB in 2010.
Toshiba Canvio 1.0 TB USB 3.0 Portable Hard Drive is a great item. It keep all my files backed up with plenty of space. Good price.
Just bought aWestern Digital My Passport 1 TB USB 3.0 Portable Hard Drive - WDBBEP0010BBK-NESN (Black)for similar price, which I'm sure will work fine like my last 2 WD drives.Final Verdict: Regardless of which machine you run this on, doesn't change the fact the USB input has a flawed design. Definitely not as stable as a WD or other leading competitors. Save yourself potential headaches/scares/lost data; for this price point you can get something better.
I received the Toshiba Canvio 1.0 TB USB 3.0 Portable Hard Drive - HDTC610XL3B1 (Blue).It is a great portable hard drive.

Toshiba 1.5 TB Toshiba Canvio 3.0 Plus Portable Hard Drive in Black (HDTC615XK3B1)I bought a Canvio 1.5 TB Drive with USB 3.0 & made it work with a 2009 13" MBP. I saw several reviews complained this drive did not work with newer MBP or MacBook Air.
I purchased this Toshiba Canvio, 1 TB, USB 3.0 external drive basically because of the 3 year warranty. Other comparables in size and price only gave a 1 or 2 year warranty with option to purchase additional years. Due to Amazon now collecting sales tax in Texas, I purchased this drive at the local WalMart for the same price of $89 plus tax. I will always support a local retailer if price is close simply because its easier to return if necessary.Setup was super easy.
I bought this during Black Friday. This is my first USB 3.0 portable hard drive. I did a few bench tests and the difference in speed is about nine times for me using an USB 3.0 port. I am glad I made the purchase and I hope this Toshiba drive will last me a few years.
