That 20 TB OWC enclosure in your B&H cart is $389. The 22 TB Exos inside it adds another $300. You're about to spend $689 because your current drive is full. Before you click buy, give me ten minutes. There's a real chance you don't need the drive at all.
I'm not going to tell you to never buy storage. I'm going to tell you to never buy storage you didn't need to buy.
Why You're Probably Buying Too Soon
Editing drives don't fill up evenly. They fill up in lumps. A documentary wraps and dumps 4 TB of rushes. A commercial leaves 800 GB of dailies. A YouTube series accumulates 200 GB a month for two years. By the time the drive hits 90 percent full, somewhere between a third and half of what's on it is footage that never made it onto any timeline, in any project, anywhere.
Think of it like a grip truck at the end of a long job. Half the gear on the truck wasn't used on the last setup. It wasn't even used on the last three setups. But nobody offloaded it because nobody had time, and now you're about to rent a second truck.
The audit below is the offload pass.
The 10-Minute Audit
You need: your current drive mounted, a calculator, and ten quiet minutes.
Minute 0-2: Measure what you have
Check the actual free space on the drive. Note the total capacity and the free space. If the drive is 16 TB and you have 1.2 TB free, you've used 14.8 TB. Write that down.
Minute 2-4: Estimate the waste fraction
If you've never measured before, use 45 percent. That's the middle of the typical 30-60 percent range. If you shoot a lot of multi-take coverage, B-roll cards, or doc-style rushes, lean toward 55 percent. If you're disciplined and only import what you've already selected, lean toward 30 percent.
For the example drive: 14.8 TB used x 45 percent = 6.66 TB potentially reclaimable.
That's a third of a 20 TB drive. Sitting on the drive you already own.
Minute 4-7: Price the waste
Open the calculator. Plug in 6.66 TB at your storage provider's rate. The point of this step isn't the cloud number specifically, it's to put a dollar figure on the wasted space so you can compare it against the new drive cost.
Or skip the cloud math and just compare directly: 6.66 TB reclaimable on your current drive vs 20 TB on a new drive at $689. The reclaimable space is roughly 34 percent of a new drive's worth, free, sitting in your file tree.
Minute 7-9: Find the worst offenders
You don't need software for this part. Open your projects folder. Sort by size, descending. Look at the top five folders. Which projects are wrapped, delivered, paid? Those are your candidates. The footage on a delivered project that's been sitting for six months is the lowest-risk waste in your entire workflow, because nobody is going to ask you to make a change tomorrow.
For most editors, two or three completed projects account for half the reclaimable space.
Minute 9-10: Make the call
You now have three numbers:
- How much space you'd reclaim with cleanup (6.66 TB in the example)
- How much that space costs you per month if you keep it (run it through the calculator)
- How much the new drive costs ($689)
If number one is more than 25 percent of the new drive's capacity, don't buy the drive yet. Spend an afternoon cleaning up first. You can always buy the drive next month if cleanup doesn't free enough.
The Counterargument
"My time is worth more than the drive."
Sometimes true. But cleanup time doesn't scale linearly with storage size, and the value of cleanup compounds. The two hours you spend identifying unused footage today saves you the same two hours of mental overhead every time you go looking for something on the drive. It saves your backup time. It shrinks your archive when the project finally gets shelved. It saves your future self from buying the next drive after this one.
Two hours of cleanup vs $689 of capex is roughly $345/hour. Editors don't usually bill at $345/hour. Producers don't usually approve drives without asking what's already on the current one.
What "Cleanup" Actually Means
The audit above gets you to "I should probably do this." Actually doing it is harder, because the dangerous part of deleting footage isn't deciding to do it, it's deciding which files. Delete the wrong clip and you get Media Offline in the middle of a client revision, and now your $689 saved cost you a relationship.
The safe rule: only delete files that are not used on any timeline in any project on the drive. Not "any timeline I remember." Not "any timeline in this one .prproj I just opened." Any timeline anywhere on the drive.
Doing that manually means opening every project file, checking every sequence, cross-referencing the file paths against the disk, and repeating for every project. On a drive with 20 projects, that's an entire workday. Which is why most editors skip it and just buy the drive.
Running the Audit Cold
If you've never done this before, do the audit on whichever drive is closest to full. Don't pick the cleanest one. Pick the one whose fullness is making you anxious. That's where the waste is.
I've done this audit with editors who were certain they needed a new drive immediately, and ended up reclaiming enough space to coast for another six to nine months. I've also done it with editors who genuinely needed the new drive. The audit just confirmed it. Either way, you spent ten minutes and you know the truth instead of guessing.
The Soft Part
Clip Sweeper exists because the "find what's actually unused on every timeline across every project" step is the hard one. It walks the project files, follows the reference chains, and gives you a clean list of what's safe to delete. But you don't need it to start. You need the calculator and ten minutes.
Before you buy that drive, go to the calculator, plug in your current storage and 45 percent waste, and look at the number. Then look at your B&H cart. Then decide.
