Bought to upgrade a PC with an overflowing 40GB system drive C:, this 500GB drive was chosen primarily because the manufacturer (Seagate) had the wisdom to produce and provide a free utility (DiscWizard, available from Seagate's website) which makes copying an old hard drive (any make) onto a new Seagate drive virtually a one-click operation for most people by using the 'disc cloning' tool included in that utility.
In the simplest mode, the tool prepares the destination disc for use, copies all existing partitions from the old drive onto the new, expanding them proportionally to fit the space available on the new drive and makes the new drive bootable. There's also a manual mode in DiscWizard which allows you to control the relative sizes of the disc partition(s) created on the new drive, so you can keep the 'recovery' partition the same size as it was and expand the C: drive to fill all the remaining space on the new drive.
My supplier supplied this drive to me as a bare drive with no instructions and no connecting leads - this is normal for an 'OEM' drive which is assumed to be being purchased by someone who knows what they are doing - but again, Seagate's website has good, clear instructions describing how to temporarily install the new drive alongside the old before swapping it into position as the new main drive.
I should point out that Seagate are not the only manufacturer who provide free disc cloning tools and advice for specific use with their own drives, but be aware that there are one or two who do not, so always check out the drive manufacturer's website before making a final decision about what to buy.
As to the Seagate Barracuda drive itself, it is very quiet and reasonably fast - very happy with it so far.
