Windows 7: Two Internal HDDs

Two Internal HDDs

In choosing my new Laptop I have a choice of one 500Gb HDD or two 250Gb HDDs

The 500GB is not Partitioned but I am assured that two 250Gb HDDs will appear in Windows as two Drives and that I can use these two Drives in the same way as one Drive Partitioned into two, which is what I'm used to

What are the advantages\disadvantages of having two HDDs?

Thank you

One advantage.....Windows 7 Backups.

One drive as the primary drive.
The second drive as the backup drive.

I would choose multiple drives. You can have a raid 1 kind of setup with one drive mirrored to the other providing complete redundancy. OTOH, if storage space is important for you, the second drive can be used simply for keeping/backing up all important data or alternatively in a raid 0 setup. Multiple hard drives protect from mechanical failure and give you more options.

Good advice. Whenever I buy a new computer the first thing I do is create a data/backup partition so I don't lose any important stuff if I have to reinstall.

Also, two smaller hard drives are quicker to search or defrag than one large one.

Disadvantage: 2 possible points of failure instead of one.

Disadvantage: I'm guessing with 2 250s, you will end up with a C of 250 on 1 drive and a D of 250 on the other. I wouldn't call that ideal. If you had a single 500, you would probably partition it into something like 100 C and 400 D--or a C of 500; either of which would be preferable in my mind to 250 C and 250 D.

Advantage: You can backup the C 250 to the D 250.

Best possible choice: A single internal 500, with another (presumably external) drive as backup.

Another advantage of 2 Hard Drives is replacing one with an SSD for the OS and using the other for user files.
