What Is Quark Drive and Is It Safe: A Full Overview

Yes, they could, and this needs to be said honestly: Quark automatically reviews uploaded content, and content that violates the rules will be blocked or deleted, causing links to fail. In particular, since April 2026, the drive industry has carried out strict clearing of overseas film and TV (American series, Korean dramas, Thai dramas, etc.), and Quark has borne the brunt, with large amounts of resources taken down and deleted, and even merely renaming files may get them flagged and cleared by the system. Ordinary, compliant personal files are generally unaffected, but to be safe, keep local backups of important files and spread copies across multiple platforms, and don't store the only copy solely on Quark.

Quark is backed by Alibaba and Alibaba Cloud, so as a product from a major company it's fairly dependable in itself, and transmission is encrypted too. But 'dependable' isn't the same as 'foolproof': the platform automatically reviews content, violations are deleted, and overseas film and TV resources in particular are strictly cleared out. The common consensus from community testing is that important, sensitive materials shouldn't be stored only on Quark Drive, and should be kept with a separate local copy plus backups spread across multiple platforms. As long as you don't stake the only copy on a single drive, the risk of losing important materials can be greatly reduced.

It can be used overseas, and you can log in in Thailand too. For registering and logging in, it's recommended to scan a QR code with WeChat (no mainland-China phone number needed), and you get 10GB just for registering. Note that Quark's servers are mainly in mainland China, so a direct connection from Thailand may load slowly and occasionally be unstable, and pairing it with a back-to-China accelerator/VPN to connect to a nearby mainland node makes it smoother. On downloading the app: iOS may require an Apple ID for the corresponding region, while on Android you can bypass that with a third-party market (such as APKPure). Overall, you can register and use it, but the network experience varies by region.

In Vietnam it's slow mainly not because of 'throttling' but because of the cross-border network: Quark's servers are mostly in mainland China, so access from Vietnam has to travel over international links, which means high latency, packet loss, and bandwidth congestion, naturally making it slow. On top of that, a free account itself downloads at only a few hundred KB/s, while SVIP's dedicated channel measures at about 11MB/s and is much faster. Ways to improve it: (1) use a back-to-China accelerator/VPN to connect to a nearby mainland node; (2) prefer 5GHz Wi-Fi or a wired network; (3) activate SVIP for heavy downloads. Note that cross-border slowness may still affect you even with membership.

Quark's free version gives you 10GB of permanent free space. That's enough for a long time for small files like documents and photos; but if you want to store lots of videos, software install packages, and other large files, 10GB will fill up fast. The widely circulated 'free 1TB' is actually temporary promotional space (triggered by saving someone else's share link to your drive), and most of it expires after about 30 to 90 days, so it's not permanent and shouldn't be treated as stable capacity. If you need large space for the long term, then consider activating VIP (3TB) or SVIP (6TB).

Each suits different scenarios. Google Drive's servers are overseas, so direct connections from Southeast Asia are generally smoother, but the source material doesn't provide direct comparison data between it and Quark. Quark's characteristics are: overseas Chinese users don't need a mainland phone number (WeChat login is enough), 10GB free, and backing from Alibaba Cloud; its drawbacks are that the servers are in mainland China so overseas direct connections are slow and need a back-to-China VPN, and it reviews and clears out content. Put simply: Google is more worry-free for access stability, while Quark is more convenient for storing Chinese-language resources and sharing with people back home. Which one suits you better needs to be confirmed by testing your actual network.

Registering directly with an overseas phone number like a Hong Kong +852 number usually won't receive Quark's verification code, because official phone-number verification only supports mainland-China numbers. The workable approach is to switch to WeChat login to bypass it: first register a WeChat account with your overseas phone number, then go to the Quark web version or app, tap 'WeChat login,' open WeChat to scan the QR code and authorize, and you're in, with the same 10GB of free space after registering. If the app pops up a 'bind phone number' prompt after login, you can simply ignore it and skip binding, and it still works.

Official phone-number verification-code registration does indeed only accept mainland-China numbers, and overseas phone numbers can't receive the code. But you don't 'have to' have a mainland number; you can bypass this with the officially supported WeChat login: first register a WeChat account with an overseas phone number, then choose 'WeChat login' in the Quark web version or app and scan to authorize, with the same 10GB of free space after registering. This is a login method built in by the company, not a workaround hack. If you're prompted to bind a phone number after login, you can simply ignore it.

Although some websites claim Quark supports email registration, no real-world guide can provide successful steps for email registration. The official entry point and all real-world guides use phone-number verification codes or WeChat/QQ authorization login, so the claim of 'email registration' isn't reliable and shouldn't be relied on. When you don't have a Chinese phone number, the most reliable approach is WeChat login: first register WeChat with an overseas phone number, then choose 'WeChat login' in Quark and scan to authorize, and you get 10GB of free space upon registering.

This is normal. Quark's registration verification code is only sent to mainland-China phone numbers, and overseas numbers can't receive it. Don't get hung up on the verification code; switch to WeChat login instead: first register a WeChat account with your overseas phone number, then open the Quark web version or app, choose 'WeChat login,' scan the QR code that pops up with WeChat and tap 'Allow authorization,' and you're in, with 10GB of free space after registering. If a 'bind phone number' prompt appears afterward, you can simply ignore it and skip binding, and it still works fine.

Quark's apps are mainly listed in the China region App Store (some versions are also in the Hong Kong region), so with a mainland-China Apple ID used overseas, or with an overseas local account, you may not find it. This is a regional listing limitation, not a ban. Solutions: (1) switch to an Apple ID for the corresponding region (China region/Hong Kong region) to log into the App Store and search and download; (2) or fall back to an Android device and install it from a third-party market (such as APKPure). Note that when downloading across regions, you may be asked to fill in a mainland address/phone number; just follow the prompts.

Quark Drive is built into the Quark app. It may not be in the Google Play Store, but Android is easy to handle: you can search for 'Quark' in a third-party app market like APKPure and install it directly (a common trick overseas users use to bypass regional restrictions), then open Quark and tap 'Drive' on the browser menu page to enter. After installing, log in with WeChat to register and use it, no mainland-China phone number needed, with 10GB just for signing up. It's best to download the installer from a trusted source to ensure safety.

Quark Drive's official support insists it 'does not throttle in any form,' admitting only that speeds fluctuate during network peak hours. But testing contradicts this: in a 100Mbps broadband environment, a free account downloads at only about 650-700KB/s (some sources even measured about 260KB/s), and a 1GB file takes around half an hour; whereas SVIP's dedicated channel measures at about 11MB/s, an obvious gap. So the actual experience is: without membership, free downloads are simply slow, and for heavy or large-file downloads, SVIP is the only stable option.

Converted to a monthly fee, Quark Drive: auto-renewing monthly is about 4.8 yuan per month; buying an annual plan is the better deal, listing for about 300 yuan per year, around 158 yuan per year normally, and dropping to about 88-110 yuan per year during major sales (roughly 7-9 yuan per month). Overseas payment is the sticking point: upgrading usually requires Alipay or WeChat Pay linked to a Chinese bank card with completed identity verification, so overseas Chinese users without a mainland card may not be able to pay, and can consider asking friends or family back home to pay on their behalf or buy the annual plan for them. The specific payment method is whatever the payment page indicates.

Quark Drive memberships are mainly paid for through Alipay and WeChat Pay, and you usually also need to link a mainland-China bank card and complete real-name verification. There's no clear statement that overseas credit cards are supported, and in practice foreign cards often run into limits when going through these two channels. The more reliable approach is to use an Alipay or WeChat account linked to a mainland bank card, or to ask family or friends back in China to pay or buy an annual plan on your behalf. Whether overseas cards are accepted depends on the actual options shown on the payment page, so test it to confirm.

Quark Drive's official privacy policy states verbatim that 'file contents are transmitted encrypted and will not be used for identification or any other purpose without your authorization.' In other words, the company commits not to use your files without your consent, and this is binding at the level of the legal text. That said, the policy does not literally promise to 'never view or never scan' files, and the platform does run automated content review on uploads. There is no direct evidence that files are 'used to train AI'; per the wording of the privacy policy, this falls under 'no use without authorization.' To be completely safe, it's best to keep a separate local copy of sensitive content. Test it to confirm.

There's no direct security comparison available between the two, so only the objective differences can be given. Quark Drive's servers are inside mainland China, it runs automated content review and screening, and overseas access is slow and may need a back-to-China VPN; however, overseas Chinese can use it without a mainland phone number (via WeChat login) and get 10GB free. OneDrive is Microsoft's overseas service and access from Southeast Asia is usually smoother. The sensible consensus for storing work files has nothing to do with the platform: don't keep important files in only one place; back them up locally and spread them across multiple platforms. Which one to choose is best confirmed by testing against your own access network and compliance needs.

This is basically a regional availability limit, not a ban. Quark's apps are mainly listed in the China App Store (some versions are also in the Hong Kong store), so naturally you won't find them with a Singapore Apple ID. Solutions: (1) Switch to a China or Hong Kong Apple ID, sign in to the App Store, then search and download (switching regions may ask you to fill in a mainland address or phone number); (2) Or switch to Android and install from a third-party store such as APKPure. Once installed, you can log in with WeChat and use it, with no mainland phone number needed.

Yes. Quark runs an automated review system on uploaded content, and content found to be in violation will be blocked or deleted, causing share links to stop working. Since April 2026, the cloud-storage industry has been carrying out a large-scale crackdown on overseas film and TV content (American, Korean, Thai dramas, and so on), with Quark hit hardest and large amounts of content taken down and deleted; even just renaming a file may still get it flagged and cleaned up by the system. It's best not to keep important or sensitive files only on Quark; always back them up locally and spread them across multiple platforms, and never leave your only copy solely in the cloud.

You may not be able to find it directly. Quark's apps are mainly listed in the China App Store, with some versions also in the Hong Kong store, and the Taiwan store may not turn them up; this is a regional availability limit, not a ban. Workable options: sign in to the App Store with a China Apple ID to download; if you don't have a China account, an Android phone can install the APK directly from a third-party store such as APKPure as a workaround. The download itself doesn't require a mainland-China phone number, and you can log in by scanning a QR code with WeChat. Test it to confirm whether it's available in the Taiwan store.

It's mainly because the vast majority of Quark's servers are inside mainland China, so overseas direct connections have to cross international gateways and run into high latency, packet loss, congested international bandwidth, and unoptimized routing, which easily leads to connection timeouts, slow loading, or even failure to open. This is a matter of physical distance plus the international link, and is separate from membership speed throttling. Ways to improve it: (1) Use a back-to-China accelerator or back-to-China VPN to connect via a nearby node and shorten the distance to Quark's servers; (2) Prefer 5GHz Wi-Fi or a wired connection, and restart your router and optical modem. Some networks in Southeast Asia really do need a back-to-China line to be stable.

Looking purely at free quota, Quark Drive gives you 10GB of permanent free space just for signing up, while iCloud only gives 5GB free, so Quark's free quota is larger. But using Quark from overseas can be slow and unstable due to cross-border access, and there's the risk of content being screened and deleted; iCloud offers stable overseas access and seamless syncing with Apple devices. Conclusion: purely on free capacity Quark is the better deal, but for overseas Chinese, iCloud is more worry-free in terms of stability and privacy experience. For important photos, it's best to keep backups on both sides rather than in just one place. Test it to confirm iCloud's specific pricing.

The available material doesn't detail the steps to turn on Quark Drive's private space or whether it needs a separate password. Generally, a drive's private/vault space requires a separate password or independent verification to protect sensitive files, and the entry to turn it on is usually under the app's "Me" or file management page. If you have sensitive files, a more reliable approach is not to keep your only copy solely on Quark (the platform performs content review and there's a risk of files being investigated and deleted); always back up important files locally and spread them across multiple platforms. The exact settings for private space depend on the app's actual features; this needs to be confirmed by testing.

Quark Drive positions itself as "smart cloud storage." Besides uploading/downloading, online preview, and file sharing, it also supports automatic backup (WeChat, QQ, and desktop files), 4K video playback, 0.5x to 5x speed, AI subtitles/translation, screen casting, and more. Members also get advanced features like cloud unzip (archives up to 8GB), PDF-to-Office conversion, and offline downloads. It's backed by Alibaba (incubated by the UC team) and is a tool that combines storage, video viewing, and document processing in one. Put simply, it's not just for storing things; you can watch videos and handle documents right inside it.
