Most cloud storage decisions start with an abstract number: 20 GB, 200 GB, 2 TB, 5 TB. Those numbers only become useful when you map them to the files you actually keep.
Here is a simple way to estimate how much cloud storage you need before choosing a plan.
Start with your file types
- Documents: usually small. PDFs, spreadsheets, and Word docs often stay under a few megabytes.
- Photos: larger and more numerous. Phone photos commonly land around a few megabytes each.
- Videos: the real storage driver. A few 4K clips can use more space than years of documents.
- Project files: design, audio, code, and ZIP archives vary wildly, so check real folders when possible.
Add a growth buffer
Do not buy exactly the storage you use today. Add room for new work, device backups, shared folders, and the files you forgot were still sitting on a laptop. A practical buffer is 25% to 50% above current usage.
Where common plan sizes fit
- 20 GB: documents, school files, light photo backup, and a real product trial.
- 2 TB: heavy photo libraries, family storage, freelancers, and small business files.
- 5 TB: larger media archives, multi-device backup, and teams with project files.
Avoid paying for bundles you do not use
Some storage plans are attached to office suites, email bundles, or collaboration platforms. That can be a good deal if you use the whole bundle. If you mainly need file storage, compare the storage plan on storage terms.
Quick answer
If you are not sure, start with a free tier that gives you enough space to upload real files. VirtualDrive includes 20 GB free, so you can test your actual folders before deciding whether you need a 2 TB or 5 TB plan.
