Stream Storage Per Hour Calculator
Calculate how much disk space one hour of streaming or recording uses based on your bitrate. Plan storage for VODs, archives, and local recordings.
Estimate total monthly storage needed for stream recordings. Input bitrate, hours per stream, and streams per month to plan your disk space.

Streaming regularly means generating gigabytes of recordings every week. Without tracking your storage usage, you can easily fill a 1 TB drive in under two months. This calculator helps you estimate your total monthly storage needs based on your streaming schedule and bitrate.
Enter your per-hour storage (or bitrate), average stream duration, and how many streams you do per month. The calculator multiplies these together to give you a clear monthly storage figure. This is essential for planning drive purchases, NAS capacity, and cloud backup budgets.
Whether you're a new streamer planning your first setup or a veteran expanding to a multi-drive system, knowing your monthly storage consumption prevents unexpected full-disk situations that can ruin recordings mid-stream.
Use the estimate as a planning baseline and adjust it once you have real session data from the game you are playing.
Disk space failures during a stream mean lost content that can never be recovered. Planning your monthly storage needs prevents this disaster. This calculator also helps you budget for external drives, NAS systems, or cloud storage subscriptions by giving you a concrete monthly consumption number.
monthly_gb = storage_per_hour ร hours_per_stream ร streams_per_month
Where:
storage_per_hour = GB consumed per hour of recording
hours_per_stream = average duration of each stream
streams_per_month = total number of streams in a monthResult: 216.00 GB/month
At 2.70 GB/hour (6,000 kbps bitrate), streaming 4 hours per session, 20 times per month: 2.70 ร 4 ร 20 = 216 GB per month. That's over 2.5 TB per year, requiring either regular cleanup or a multi-terabyte storage solution.
Storage planning is one of the most overlooked aspects of streaming. New streamers often start with a 500 GB drive and are surprised when it fills up in weeks. A systematic approach โ calculating monthly needs and scheduling regular maintenance โ prevents data loss and keeps your workflow smooth.
Consider a tiered approach: use a fast NVMe SSD (500 GBโ1 TB) for active recording, a larger SATA SSD or HDD (2โ4 TB) for recent archives, and cloud or external storage for long-term backups. This balances speed, capacity, and cost effectively.
If you're consistently using more than 75% of your recording drive, it's time to either clean up or expand. Running a drive near capacity can slow write speeds and increase the risk of recording failures. Plan upgrades before you hit capacity, not after.
Last updated:
A full-time streamer doing 5 streams per week at 4 hours each with 6,000 kbps bitrate needs about 216 GB/month or 2.6 TB/year. A 4 TB drive gives roughly 18 months of headroom before needing a cleanup or upgrade.
Most streamers keep recordings only long enough to extract highlights, then delete the raw files. If you want permanent archives, invest in cheap high-capacity HDDs or cloud cold storage like Backblaze B2 at $0.005/GB/month.
No, stream duration has no effect on quality. Quality is determined by bitrate, resolution, and encoder settings. Duration only affects total file size linearly โ twice as long means twice the storage.
Delete old raw recordings you've already edited. Remux large MKV files to compressed MP4. Lower your recording bitrate for future streams. Move archives to cheaper storage like external HDDs.
SSDs are better for active recording due to faster write speeds, reducing the risk of dropped frames. HDDs are fine for storing archived recordings. Many streamers use an SSD for active recording and move finished files to an HDD.
In a dual-PC setup, the streaming PC handles encoding and usually stores the local recording. Storage needs are the same per bitrate โ the dual-PC advantage is encoding performance, not storage efficiency.
