Quark Drive is a storage service carrying the Quark name of a large Chinese internet company, built on top of that company own cloud infrastructure. What it aims at is not the longest list of features but an absence of interruptions. The app opens straight into the file list, with no splash advertisement and no feed pushed in front of the reader, and moving around inside folders stays quiet. For anyone worn down by pop-up windows and promotional banners in one storage service after another, that restraint is the first thing noticed, and it is the reason the whole product feels lighter than its feature count would suggest.

Transfer speed, and sharing that does not fight back

Speed is the heart of the experience, because storage that takes an afternoon to hand back a folder is storage nobody uses twice. Basic downloads on a free account are not deliberately throttled, so backing up photographs or pulling down course material feels smooth, and a paying member gets a faster dedicated channel on top of that. Sharing works by link: an extraction code and an expiry date can both be set, generated links can be managed in bulk rather than one at a time, and a transfer assistant moves a file between a phone and a computer by scanning a code instead of mailing it to oneself.

The media side is where the effort went

Video playback is not an afterthought here. The player runs at up to 5x speed, handles the original and higher-quality streams, and can produce subtitles in a single action, which is what makes a long lecture recording or a series watchable in whatever time is actually available. Playback can be cast to a television set as well. Photographs are arranged by timeline and by smart categories, so hunting for an old picture can be quicker here than scrolling through the album sitting on the device.

Small tools inside the same window

Beyond storing and watching, a set of everyday utilities is built in. ZIP and RAR archives extract online, so the contents of a package can be inspected without fetching the whole thing first; PDF conversion, photograph scanning, and online preview and editing of documents all live in the same place instead of in separate applications. Automatic backup covers common sources such as the phone album and files received in a chat app, and once it is switched on it syncs incrementally rather than copying everything from the beginning each time.

Security in layers

With anything kept in the cloud, the question that matters most is who can reach it, and how easily a mistake turns into an exposure. Files are encrypted in transfer and while stored, and the service has passed the domestic graded protection certification. Identity papers, contracts and the like can be put into a separate encrypted space, which lowers the risk simply by keeping them out of the ordinary file list. A link that leaves the account carries both an extraction code and an expiry, and it stops working on its own once that date passes, so sending something to a person outside is far less uneasy than it would otherwise be.

Free is usable, membership adds room

As of 2026-09 an individual gets 10GB of permanent free space, and a new account that saves files from someone else share receives extra temporary capacity on top of that. Uploading, downloading and online preview are open without payment, which means the free tier is not a demonstration but something that can be lived in. A membership plan exists for people who need more room and a better transfer experience, and it can be expanded to as much as 6TB. The service reaches phones, computers, tablets and televisions, so whatever is uploaded once stays reachable from any of them.
