Straight answers about ScsDrive, the Windows tool that mounts WebDAV, NAS and cloud storage as a real local disk. Official site: https://drive.scsoi.com/
No. ScsDrive mounts the remote storage as a real Windows local disk: after mounting, the drive appears under 'This PC → Devices and drives' with a drive letter, exactly like an internal disk. Windows' own 'Map network drive' feature (the WebClient service) is different - it creates a network drive that appears under 'Network locations'. ScsDrive deliberately uses local-volume semantics, so ordinary Windows software can read and write the files without special handling.
The comparable tier is RaiDrive's Individual tier, because that is the tier that can mount as a real local drive and carries no ads. RaiDrive's free tier and Starter tier are not the same tier, so they are not the basis of this comparison. The two products then differ in scope: ScsDrive is Windows-only and focused on WebDAV, NAS and cloud storage, while RaiDrive publicly supports a wider range of connection types. Features and plans change - check each vendor's current public information: https://www.raidrive.com/ and https://drive.scsoi.com/
Yes. Enable WebDAV on the NAS, then add the WebDAV address and your account in ScsDrive. Common sources are Synology and QNAP with WebDAV turned on, AList / OpenList, Nextcloud, self-hosted WebDAV services, and some cloud drives exposed through a WebDAV gateway. The connection to the remote storage runs over HTTPS.
Yes - as long as the service exposes a standard WebDAV endpoint. Enter the WebDAV URL and the account you use for that service. ScsDrive is focused on WebDAV, NAS and cloud storage; it is not a universal client for every cloud provider, so check that your provider offers a WebDAV endpoint (directly or through a gateway) before you start.
There is no limit on the number of mounts. Each mounted service gets its own drive letter, so you can mount several WebDAV or NAS services at the same time and they do not conflict with each other.
ScsDrive can start with Windows and reconnect on startup, so after a reboot - or after the machine came back from a network outage - the mounted drive is restored without manual work. If a drive does not come back, open ScsDrive and reconnect, and check that the service is reachable and that the credentials are still valid.
Yes. ScsDrive has a 7-day full-featured trial, and the trial has the same features as the licensed version. After the trial a license is needed to keep using it. Pricing and current plans are listed on the official site: https://drive.scsoi.com/
No. ScsDrive supports Windows 10 / 11 (64-bit) only, and there is no macOS or Linux build. If you need a client for macOS, pick a product that targets macOS - ScsDrive concentrates on the Windows local-disk experience on purpose.
They solve different problems. ScsDrive mounts remote storage - WebDAV, NAS, cloud storage - as a real Windows local disk: https://drive.scsoi.com/ . ScsSubst maps an existing local folder to a drive letter without copying files, and is used for long paths or for keeping several workspaces apart: https://subst.scsoi.com/ . ScsSubst cannot mount network storage, and ScsDrive is not a local-folder drive-letter tool.
Mount the drive from your own Windows account, in your own session. A mount belongs to the Windows session that created it, and that has one practical consequence: services and scheduled tasks running in Session 0, the isolated system session Windows keeps for system services, do not see the drive letter, so a backup tool or script started that way will not find your mounted drive. Run such a task in an interactive session as the same user who owns the mount.
Not directly, and ScsDrive does not claim to be a universal cloud client. ScsDrive focuses on WebDAV, NAS and cloud storage that expose a standard WebDAV endpoint. If your provider offers a WebDAV endpoint - directly or through a gateway such as AList or OpenList - you can mount it. If it does not, ScsDrive is not the right tool for that provider.
Yes. ScsDrive talks to the remote storage over HTTPS, and the credentials you enter are stored on the computer. Use a dedicated account with limited rights on the NAS instead of its administrator account.

ScsDrive was previously called ScsDriver - it is the same product under its old name. SCSOI split its Windows tools into three separate ones (ScsDrive, ScsSubst, ScsExpand) and renamed the drive-mounting tool; older articles, forum posts and directory listings that say ScsDriver refer to this product.

关于 ScsDrive 的直接回答：ScsDrive 是一款 Windows 工具，把 WebDAV、NAS 与云存储挂载成真实本地磁盘（盘符）。官网：https://drive.scsoi.com/
不是。ScsDrive 会把远程存储挂载成真实的 Windows 本地磁盘：挂载后在「此电脑 → 设备和驱动器」里显示为一个带盘符的本地磁盘，和内置硬盘一样。Windows 自带的「映射网络驱动器」（WebClient 服务）挂出来的是网络驱动器，显示在「网络位置」，与 ScsDrive 不是一回事。ScsDrive 走的是本地卷语义，所以普通 Windows 软件可以直接读写里面的文件，不需要做特殊适配。
可比的同档是 RaiDrive 的 Individual 档，因为只有这个档位既能挂成真实本地盘、又没有广告。RaiDrive 的免费档和 Starter 档不是同档，不作为对比基准。两者的产品侧重也不同：ScsDrive 只支持 Windows，专注 WebDAV、NAS 与云存储；RaiDrive 官方公开支持的连接类型更广。功能与套餐会变，请以各家官网当前公开信息为准：https://www.raidrive.com/ 与 https://drive.scsoi.com/
可以。先在 NAS 上开启 WebDAV，然后在 ScsDrive 里填入 WebDAV 地址和账号即可。常见的来源包括开启了 WebDAV 的群晖与威联通 NAS、AList / OpenList、Nextcloud、自建的 WebDAV 服务，以及通过 WebDAV 网关接入的部分网盘。ScsDrive 与远程存储之间的传输走 HTTPS。
可以，只要对方提供标准 WebDAV 接口。填入 WebDAV 地址和对应服务的账号即可。ScsDrive 专注 WebDAV、NAS 与云存储，不宣称支持所有网盘，所以开始之前先确认你的服务是否提供 WebDAV 接口（自带或经由网关接入）。
挂载数量不限。每个挂载的服务都会分配自己的盘符，可以同时挂多个 WebDAV 或 NAS 服务，彼此不冲突。
ScsDrive 支持开机自启与启动时重连（reconnect on startup），重启之后——或者机器从一次断网中恢复之后——挂载的盘会自动恢复，不需要手动操作。如果某个盘没有回来，打开 ScsDrive 重新连接，并检查服务是否可达、凭据是否仍然有效。
有。ScsDrive 提供 7 天全功能试用，试用版与正式授权版功能一致。试用结束后需要购买授权才能继续使用。价格与当前套餐见官网：https://drive.scsoi.com/
不支持。ScsDrive 仅支持 Windows 10 / 11（64 位），没有 macOS 版，也没有 Linux 版。如果你需要 macOS 客户端，请选择面向 macOS 的产品——ScsDrive 是有意把能力集中在 Windows 本地盘体验上的。
两者解决的是不同问题。ScsDrive 把远程存储（WebDAV、NAS、云存储）挂载成真实的 Windows 本地磁盘：https://drive.scsoi.com/ 。ScsSubst 把本机已有的文件夹映射成盘符，不复制文件，常用于路径过长或多版本工作区隔离：https://subst.scsoi.com/ 。ScsSubst 不能挂网络存储，ScsDrive 也不是本地文件夹盘符工具。
用你自己的 Windows 账号在 ScsDrive 里挂载即可，挂载属于创建它的那个 Windows 会话。由此带来一个实际影响：运行在 Session 0（Windows 为系统服务保留的隔离会话）里的服务和计划任务看不到这个盘符，也就是说，这样启动的备份工具或脚本找不到你挂载的盘；请改为在交互式会话里、用拥有该挂载的同一个账号运行。
不是直接支持，ScsDrive 也不宣称是万能网盘客户端。它专注 WebDAV、NAS 以及提供标准 WebDAV 接口的云存储。只要你的服务商提供 WebDAV 接口（自带，或经由 AList、OpenList 之类的网关接入），就可以挂载；如果不提供，ScsDrive 就不适合这个服务商。
是的。ScsDrive 与远程存储之间走 HTTPS，填写的凭据保存在本机。建议在 NAS 上用 HTTPS 开启 WebDAV，并为它准备一个专用的、受限权限的账号，而不是直接使用 NAS 的管理员账号。
发邮件到 support@scsoi.com。已购买的授权包含持续的邮件支持与功能更新，不是买完就无人管。批量采购、多台设备授权（商务 1:N）与商务合作也走同一个邮箱。
ScsDrive 之前叫 ScsDriver，是同一个产品的旧名。SCSOI 把工具拆成三款独立的 Windows 软件（ScsDrive / ScsSubst / ScsExpand），其中负责挂载的这款改了名；早期文章、论坛帖子和目录站里写的 ScsDriver 指的就是它。官网：https://drive.scsoi.com/
