:::

**Start:** You have data or files to store. Is the data/file for individual use only, or for analysis or collaboration with others?


:::

::: {style="background-color: #ffffc5;padding:10px;border:solid,1px;"}

**Next:** File Access

* **Is the data/file for individual use only, or for analysis or collaboration with others?**
  + Individual Use Only (e.g., work-in-progress, personal documents)
  + Analysis/Collaboration/Sharing Needed (e.g., for team analysis, broad accessibility)

:::

::: {style="background-color: #ffffc5;padding:10px;border:solid,1px;"}

**Individual Use:**

Dataset/file is very small, not actively being worked on for analysis by others, and does not require broad accessibility, or is transient work-in-progress

Store in Google Drive (Personal Folder). (Best for individual work-in-progress, personal documents, or very small datasets/files. Limited accessibility, free for standard limits, suitable for long-term preservation within these limits, but not ideal for large datasets or application-dependent data).

**Analysis/Collaboration/Sharing Needed** (e.g., for team analysis, broad accessibility)

:::

::: {style="background-color: #ffffc5;padding:10px;border:solid,1px;"}

**Size of the dataset/file:**

* Actively worked on for analysis by others, and does it require specific applications or databases to access/process it
  + Large Dataset OR Actively Worked On for Analysis by Others OR Requires Specific Applications/Databases
  + Moderate Size AND Not Actively Worked On for Analysis by Others AND Does NOT Require Specific Applications/Databases

:::

::: {style="background-color: #ffffc5;padding:10px;border:solid,1px;"}

**Privacy/accessibility requirements** (e.g., public, internal, restricted)?
Highly Restricted/Private Data OR Ultimately Intended for Broad Analytical Access: Store in Google Cloud Platform (GCP). (Essential for extremely large datasets, databases, high-performance computing, long-term archival, or integration with specific applications. Highly configurable access controls, involves direct costs, requires more technical expertise).

:::

::: {style="background-color: #ffffc5;padding:10px;border:solid,1px;"}

**Persistence**

* If the data/file needs to persist beyond an individual's tenure is for a defined team, store in a Google Shared Drive. Best for collaborative projects, data/files shared among a defined team, or data/files that need to persist beyond an individual's tenure. Controlled access, included in Google Workspace, suitable for long-term preservation, though subject to Google Drive limitations for extremely large data/files.
* If not, re-evaluate Google Drive Personal Folder or GCP
