HDD RAID TCO Worksheet Sample

A while back I created a HDD TCO worksheet showing the relative costs of certain drives in no real context. This spreadsheet aims to calculate the total cost of ownership for a RAID array, which is a much more involved affair. https://docs.google.com/spreadsheets/d/1dM2vO08gmX3VwYyJtTE5D1Gu75TTU-nUW95j1_DVx8c/ That’s a read-only version, but you can easily make your own copy to play with: If you have a Google account and are logged in, you can just hit File -> Make a Copy.. to save it to your own Google Drive.

Choosing a Disk Drive: HDDs, SSDs, and Then Some

Please download the Excel version and use this for any drive that you want. If you make any interesting changes or large scale updates, I’d love to see it, so please let me know!

I also added a bunch of notes so you know what I meant with all the field names.
