Hard drive for OS

  1. My current setup is a 80GB SATA II 8MB cache Seagate hard disk which has the OS on it.

    I have just bought a 500GB SATA II 32MB cache Hitachi hard disk. My question is:

    should I use the 500GB as a storage device and keep my OS on the 80GB


    Put the OS on the 500GB as a partition and then use the rest of that as storage and the remaining 80GB drive as secondary storage?

    Yes I would leave the OS on the 80GB and use the 500 for storage.

    I would use the second option - OS on 500GB with partition and use the rest as secondary storage.

    Your 80GB SATA should be running at 5400RPM am I correct? The 500GB should be running at 7200RPM (not to mention the cache sizes on each). I would always put my OS on the faster hard drive .... just my opinion.

    both drives are 7200 so speed is the same which is why i was thinking to still use the 80gb for OS. Difference in cache won't make much of a difference unless i'm transferring large amounts of data right?

    Store your data FAR AWAY from the OS. 80GB = system drive; 500GB = "volume" drive.

    With a volume drive, partitioning isn't really necessary. Simple folders can provide the separation. And since there is much less chance of infection on a separate volume drive, partitioning just takes time and wastes space. Download to the "C:/" drive, scan with security programs, then move the files to the volume.

    There isn't much practical reason to partition an 80GB drive. With a few games installed, the drive will be approaching 1/3 to 1/2 full. Data access, is fastest in this portion of any drive.

    To have a larger cache on the drive, you would have to go to a 250GB, which I think Seagate sells a 32MB model. I wouldn't worry too much about.

    Read and write speeds under different data configurations and even what effect different RAID configurations on those numbers, will just confuse the issue and confuse you.
