Dataset inputs
Formula used
Tabular raw storage: rows × bytes stored in each row. Column types determine the estimated row size. Missing-value overhead is added afterward.
Image raw storage: width × height × channels × bit depth ÷ 8 × images. Audio uses duration × sample rate × channels × bit depth ÷ 8. Video also multiplies by frames per second.
Total project storage: stored data + processed copies + augmentation + caches + temporary files. Copies, replication, backups, snapshots, and safety margins are then included. Growth forecasting compounds the recommended capacity annually.
Stored dataset = (Raw × Compression factor + Annotations + Metadata) × (1 + Overheads) Primary working storage = Stored + Processed + Augmented + Cache + Temporary Recommended capacity = (Active copies + Backups + Snapshots) × (1 + Safety margin) Future capacity = Recommended capacity × (1 + Annual growth rate)^Years
How to use
- Select the dataset type and storage format.
- Enter dimensions, sample counts, or average file sizes.
- Set compression, annotation, metadata, and overhead assumptions.
- Add preprocessing, augmentation, cache, and temporary storage.
- Configure copies, replication, backups, snapshots, and versions.
- Enter growth, cloud pricing, and network transfer assumptions.
- Calculate, compare formats, then export or copy results.
Example data
| Dataset | Key inputs | Planning notes |
|---|---|---|
| Tabular customer events | 1,000,000 rows, 27 columns | Parquet usually reduces repetitive values effectively. |
| Image classification | 100,000 images, 1024 × 768 RGB | Annotations and augmented copies can dominate storage. |
| Speech recognition | 50,000 clips, 30 seconds, 44.1 kHz | Lossless audio and transcripts require additional space. |
| Video detection | 1,000 videos, 1080p, 30 FPS | Codec assumptions strongly affect actual stored size. |
| NLP corpus | 1,000,000 documents, 500 tokens | Token IDs, masks, and caches should be included. |
Frequently asked questions
What is raw dataset storage?
Raw storage is the uncompressed size calculated from dataset dimensions and data types before format compression or operational overhead.
Why can processed storage exceed raw storage?
Preprocessing may create normalized copies, tokens, spectrograms, resized images, extracted frames, embeddings, indexes, and intermediate files.
What does stored after compression mean?
It is the percentage remaining after compression. Enter 30 when compressed files occupy about thirty percent of raw storage.
Should annotations be included?
Yes. Bounding boxes, masks, transcripts, labels, prompts, and metadata may become significant in heavily annotated datasets.
What is a replication factor?
Replication stores multiple copies across disks, nodes, or regions to improve availability, durability, and read performance.
How are incremental backups estimated?
The first retained backup is treated as full. Later backups store the selected percentage of changed data.
Why compare decimal and binary units?
Cloud vendors often price decimal gigabytes, while operating systems may display binary gibibytes. Their values differ slightly.
Are format comparison values exact?
No. They are planning presets because real compression depends on entropy, schema, encoding, chunking, and compressor settings.
How much safety margin should be used?
Twenty percent is a practical starting point. Rapidly growing or uncertain pipelines may require a larger reserve.
