Dropbox
The original file-sync service: block-level sync that still sets the standard, from $9.99/mo for 2 TB.
About
Dropbox invented mainstream file syncing and its block-level delta sync remains the benchmark — changed chunks upload, not whole files, which is why large files sync so much faster here than on rivals. The lineup for 2026: Basic (free, 2 GB, three devices), Plus at $11.99/month or $9.99/month billed annually for 2 TB, Professional at $19.99/month or $16.58/month annual for 3 TB plus Dropbox Sign and 180-day version history, and business tiers Standard ($18/user/month) and Advanced ($30/user/month, 3-user minimum) with pooled storage and SSO. Desktop clients run on Windows, macOS, and Linux; Paper handles lightweight docs.
Honest limits: the free tier has been 2 GB since 2008 and feels stingy next to Google's 15 GB. There is no native end-to-end encryption, prices have risen repeatedly since 2022, and it is a storage-only play — email, calendar, and office tools come from somewhere else. No published performance benchmarks found; speed claims are provider-claimed.
What it can do
- Block-level delta sync for fast large-file updates
- File versioning (30 days on Basic/Plus, 180 days on Professional)
- Password-protected and branded shared links (paid tiers)
- Dropbox Sign e-signatures (Professional and up)
- Dropbox Transfer for sending large files up to 250 GB
- Desktop apps for Windows, macOS, Linux plus iOS/Android
- Selective Sync and Smart Sync to save local disk space
Setup
Create a free account, install the desktop client, and move or copy files into the Dropbox folder to start syncing.
Prerequisites
Nothing — the free Basic plan needs only an email address.
