Two HDD's

Archived from groups: comp.sys.ibm.pc.hardware.storage (More info?)

I know this is a silly question, but apart from the obvious (more memory), Is there an
advantage to having 2 HDD's?

Another advantage is you can back up important files from your primary
drive or even image the entire thing onto the second one. That way if
your drive fails, you've got backups.

Silly nilly. HDDs do not equate with memory.

1) Backups. (eg. manually, or mirrored RAID setups)
2) Faster file copies, esp. when working with large files. HD to HD
copy is faster than HD to same HD copy.
3) Faster everything (if stripped RAID setup).
4) Seperate data from the OS HD. You can pull the data HD and bring it
to any other PC easily w/o affecting the boot OS & programs on the main HD.
5) You like more heat in a cold room ,) Two HDs produce more heat, so
you get warmer faster ,)=

Just to go on with your list

5) separating apps, data, and OS onto separate HD's can give you better
performance for some apps. Taken one step further, seperating the logs on
to separate disks, for things like Exchange or SQL, improves the
performance as well.

6) Don't forget moving the paging file to it's own disk can also have a
performance increase.

In practice the answer is "it depends" on what you're running. At home I
have 5 hard disks, with OS, Apps, Swap, Data, and Temp files, spread across
different disks. This results in the least amount of contention for a disk
resource, and it's pretty simple to set up. It doesn't require a RAID
controler or stripped configuration to get a performance benefit. It's not
complicated at all to manage or maintain.

At work, we run everything from Citrix / Terminal Servers to Exchange and
SQL boxes, and real-time transaction servers. Each has different disk
configurations to suit the application in question. For example, Terminal
servers don't access the OS much once they are booted. They access the
apps a little more. But they spend a LOT of time writing profiles and temp
files. So that's the area where you need to watch for performance issues.
Typically we use perfmon to try and find out where bottlenecks are
occurring.
