  1. I am sorry to tell the HDD quality wouldnt be great to fit in desktop system......

    1. No issues using the HDD on my Desktop.. all's working well!

  2. Cheers, that was enough to get me into the drive - I'm not sure how well it would work in a desktop system, but it works well in my NAS drive, and leaves me with a spare SATAT->USB3 caddy. :)

  3. Nice and very helpful information i have got from your post. Even your whole blog is full of interesting information which is the great sign of a great blogger.

    Acer - Aspire Ultrabook 13.3" Laptop - 4GB Memory - 128GB Solid State Drive - Champagne

    Acer - Aspire 15.6" Laptop - 6GB Memory - 500GB Hard Drive - Matte Silver

  4. have no idea why folks think this wont work on a desktop, its just a standard barracuda inside, in fact these externals are cheaper than the bare drives... so even if you need an internal buy this and you have a free usb box for the drive you are replacing or whatever :)

  5. Why bother to go to all of this trouble when hard drives can be installed right out of either OEM or retail packaging...makes no sense at all?
