Good External Backup HDD for using on 3 PCs

Hi, i am planning on buying a 3TB External HDD to backup some files of my 3 different PCs. 2 of them Windows XP Pro Sp3 x32, and one Windows 7 Ultimate x64.

Do you have anny recommendations for a good drive and program? Are the included Bakcup software good enough for handling 3 different computers?

Here are the 2 options that i have in mind, but please recommend me others if you think there are better solutions on a "smilar" price range...

Seagate Backup Plus 3 TB USB 3.0

WD My Book 3TB External Hard Drive Storage USB 3.0

LaCie 3 TB Porsche Design P'9230 USB 3.0

LaCie 3 TB Minimus Hard Disk USB 3.0


Note: Also please clarify me this. I read somewhere that 3TB HDDs or 4TB HDDs where "better" or more "reliable" than 2 TBs , because  they have more platters? or something like that.....well i dont remember excactly the words...But i know somebody mentioned that a 3TB was better for some reason, besides the obvious of more space to store files....

Thanks

I suggest using Paragon's backup and recovery utility. There's a free version that works fine (but it can only be used for private use). I don't recommend using finished USB drives, but rather either using empy USB cases to which you add your own drives, or docks, but you know that already. I also wouldn't use any backup tool that came with such a device. Those I've seen look very basic.

For Windows 7 you can also use the builtin backup tool.

Are all computers need full backups or just some folders?

You can use something such as EaseUS Todo Backup  

The paid version will allow you to just restore folders and files and disk images and more. Where the free does just disk images.

Any of the drives will work.

Hi, thanks for the recommendations.

All computers will not need full backups, just some folders.

For file copy: Syncback is free, so is the ms synctoy, and robocopy works great in a script.

For the drive, if you are moving it around, I've found the extra $$ for a g-raid is worth it for the metal enclosure. I've cracked so many of those seagate and WD plastic cases its rediculous.

The biggest causes of HDD failure are excessive shock / vibration and overheating.
More platters = more moving parts with more heat.

All manufactures offer similar quality HDDs within the relative price ranges.
You need to consider if the HDD will be running for long periods and subject to shock or possible rough treatment...more expensive HDDs have superior shock resistance and also a built in cooling fan.
Cheaper models may just have the option to install a cooling fan and their plastic cases are not robust.

Thanks guys, i have decided this for this time and situation to go with a Bare Drive and use it with my External DOCK or soon i will by an external enclosure. As soon as i get my HDD delivered i will try out the software recommendations.

For other situations (My girlfriends MAC, and my NAS) i have decided to go with Brand External Drives, like the ones i  mentioned, since it will be easier to use and manage (at least for my girlfriend)...
