Our take
Coming from the Proton ecosystem, this is the natural choice if you already use their mail or VPN and want encrypted storage under the same Swiss roof and account. The honest limits are that it is younger than Proton’s other products, so desktop and sync clients have been catching up, and the free 15GB is modest. Strong if you are consolidating into Proton; as a standalone drive judged purely on features, more established options compete hard.
