If you’re using an SSD, there are a few things you can do to extend its life. One of the things you can do is move the search index cache.
The Search Index I/O activity can take a considerable toll on your system drive by keeping it busy. If you have an SSD, this may reduce its life. By moving the index to a separate drive, you can increase overall performance of your PC (more noticeable under load) and preserve the life of your SSD.
Move the Search Index to Another Drive
1. Click Start, type index in the search bar, and click indexing options
2. Click Advanced
3. Click Select new and select a new location on a different physical hard drive:
4. Click OK
The service will restart and moved the index to the new drive:
Note: While the index service is rebuilt on your new drive you may notice a decrease in system performance.
