Upgrading my hard drive with SSD

I still think the dual drive config is ideal. Lets look at this from use and space.

If you have the dual SSD/HDD config you don't need as large a SSD as you'll use the SSD as your Boot drive (OS) and hosting your apps. In addition by default the SSD will be used for virtual RAM and memory paging. Here the HD will only have your data. You only need a set of cables and some double sided tape to hold the SSD in.

All in all this will be the cheapest solution and gain you the speed of the SSD and yet the deep storage of your HD with little effort with file access.

If you swap out your current HDD for a SSD you'll need more space to hold everything. In addition you'll need additional parts a 3.5" to 2.5" adapter frame and you'll need to add in the now missing thermal sensor the HDD had for the systems cooling system (SMC) to work correctly. In order to salvage your HDD's data you'll need this adapter: Universal Drive Adapter

All in all this will be a more expensive project while you'll gain the speed of the SSD it will be a more expensive unit and you still have three parts to get, and lastly you have more effort to recover your files.
