Why Google Drive, OneDrive, and Dropbox Are Slow for File Transfers

The Two-Trip Problem

When you "transfer" a file through Google Drive, OneDrive, Dropbox, or SharePoint, the file takes two trips. First, it uploads from your device to the cloud server. Then the recipient downloads it from the server to their device. Your file crosses the internet twice, and both trips take time.

This matters because upload speeds are almost always slower than download speeds. Most consumer internet connections are asymmetric—you might have 300 Mbps download but only 30 Mbps upload. That 20 GB folder takes about 10 minutes to upload at 30 Mbps, even before the recipient starts downloading. The total transfer time is upload time plus download time, and the upload leg is usually the bottleneck.

With peer-to-peer transfer, the file makes one trip. Your device sends directly to their device. The sender's upload speed is the only bottleneck—there's no round-trip through a server in between.

File Size Limits

Every cloud drive has per-file size limits, and they're smaller than you might think for daily use with large media files.

OneDrive and SharePoint cap individual files at 250 GB. That sounds large, but a single uncompressed 4K video project or a machine learning dataset can easily exceed it. SharePoint adds its own complexity: libraries are limited to 300,000 files for reliable sync, file paths can't exceed 400 characters, and certain characters in filenames will cause sync failures on Windows.

Google Drive allows up to 5 TB per file, which is generous. But there's a daily upload cap of 750 GB. If you need to push a 1 TB dataset, you physically cannot do it in a single day through Google Drive. You'll hit the cap and have to wait 24 hours to continue.

Dropbox limits uploads to 50 GB through the web interface and 2 TB through the desktop app. The free tier gives you 2 GB of total storage—barely enough for a handful of large photos, let alone video files.

P2P transfer has none of these limits. The file goes directly from one disk to another. The only limit is the size of the recipient's storage.

Storage Costs Add Up

Cloud drives are storage products. You're paying to keep files on their servers, not to transfer them. But many people use cloud storage as a transfer mechanism—upload a file, share a link, the recipient downloads it, then both of you delete the cloud copy. You're paying for storage you don't actually want.

Free tiers are small and getting smaller. Google Drive gives you 15 GB shared across Drive, Gmail, and Photos. OneDrive gives you 5 GB. Dropbox gives you 2 GB. If you regularly move large files, you're paying $10–20/month for storage that serves as a temporary transfer buffer.

With P2P transfer, there's no cloud storage involved. Files go from your device to theirs. No monthly fee, no storage management, no cleaning up shared links afterward.

Upload Throttling and Speed Caps

Cloud services often throttle upload speeds, either by policy or by infrastructure constraints. SharePoint and OneDrive are particularly known for this—large uploads can slow down dramatically midway through as the service rate-limits your connection. Google Drive's 750 GB daily cap is an explicit speed limit: even if your connection can push faster, Google won't accept more than 750 GB in 24 hours.

These limits exist because cloud providers manage shared infrastructure. Your uploads compete with millions of other users for the same server capacity. The provider has to throttle individual users to keep the service stable for everyone. That's a reasonable engineering decision, but it means your transfer speed is determined by the provider's policies, not by your internet connection.

A P2P transfer uses your full connection speed. No shared infrastructure, no throttling, no daily caps. Your bandwidth is your bandwidth.

Privacy: Your Files on Someone Else's Server

When you upload a file to a cloud drive, a copy of that file sits on the provider's servers. It's governed by their terms of service, their retention policies, and their security practices. For personal photos this might not matter much. For client work, unreleased projects, financial documents, or sensitive datasets, it's worth thinking about.

Even if you delete the shared link, the file may remain on the provider's servers in backups, caches, or version history. You're trusting the provider to handle your data according to their stated policies—policies that can change. (We wrote about this in the context of WeTransfer's TOS changes.)

P2P transfer avoids this entirely. The file exists on your device and the recipient's device. No third-party server ever holds a copy. There's no TOS governing your file in transit because no one else possesses it.

When Cloud Storage Is the Right Tool

Cloud drives aren't bad—they solve a different problem. They're excellent when you need files accessible from any device without coordinating with another person, when you need collaboration features like real-time editing and version history, when multiple people need ongoing access to a shared folder, or when you need automatic backup of important files.

Google Drive, OneDrive, and Dropbox are storage and collaboration tools. They're designed for keeping files available and synced, not for moving large amounts of data from point A to point B as fast as possible.

When P2P Is Faster

P2P transfer makes more sense when you're sending files to a specific person or device and don't need them stored in the cloud. The common cases: sending a finished video project to a client, sharing raw footage with an editor, distributing a dataset to a collaborator, pushing a build to a testing machine, or delivering design files to a client for review.

In all of these, the cloud upload is wasted work. You don't want the file stored on Google's servers—you want it on the other person's machine. P2P skips the middleman.

Handrive is built for exactly this. Files go directly between devices, end-to-end encrypted, with no file size limits and no storage fees. The transfer protocol is designed for speed over any distance—UDP-based, latency-independent, and built to saturate your available bandwidth.
