DaisyDisk vs DriveDx
Side-by-side comparison of features, pricing, ratings, and alternatives.
DaisyDisk is a disk space analyzer for macOS that scans internal and external drives, SSDs, HDDs, USB and Thunderbolt devices, network volumes, and cloud storage folders such as Dropbox, Google Drive, OneDrive, and Box to show exactly what is consuming disk space. Results are rendered as an interactive circular sunburst chart, letting users click into folders and drag files to a collection area for deletion, with system and application files automatically protected from accidental removal. The app is built for speed, with the developer claiming a full drive scan takes about 15 seconds versus several minutes in Finder, and it can run with administrator privileges to reveal hidden system files. DaisyDisk is sold as a one-time $9.99 lifetime license covering up to 5 personal Macs, available directly from daisydiskapp.com and on the Mac App Store, with no subscription fees and a 30-day money-back guarantee.
DriveDx is a macOS utility that continuously analyzes S.M.A.R.T. attributes and other health indicators for internal and external hard drives and SSDs, flagging each drive as OK, Failing, or Failed. The goal is to surface early warning signs of drive failure while there's still time to back up data, rather than discovering a dead drive after the fact. It runs background monitoring with desktop alerts, offers short and extended self-tests, and calculates separate health and performance ratings using algorithms tuned differently for SSDs versus traditional HDDs. It also supports scheduled email reports for remote or headless Mac monitoring.
