Resizing your HDD partition to improve performance

Gamers and IT professionals along with home users that are power users can significantly improve HDD performance by shrinking the partitions on their HDDs.

By using the Disk Management utility in Windows you can shrink large HDDs as needed to increase performance.

How does this work?

For optimal system performance on an IIS server, you should install Windows and IIS on one drive and data on another drive.  When you install Windows, you can partition the entire drive with the full amount and use disk management to shrink the drive later OR you can give yourself enough space +30% for temp files (etc.).  By shrinking the drive, this optimizes the drive by not only placing files where they should go but allows the drive to become efficient by having only a certain amount to index and read.

The same should be done for the data drive.  You can extend the partition as data grows and space is needed.

Hopefully my math is right on the percentages…

Notes:

Partitioning SSD drives will show a gain, but because of the economics behind SSDs at this time, it may not be economically feasible.  SSD drives can be optimized in other ways.

Linux and Apple drives can be optimized by partitioning.

Golden Rule – Do not use the unallocated amount.  Save it for growth or files that are not accessed often.
