Powered by quad-core 1.7 GHz processor, the TS-231K provides 2 drive bays storage space to securely store your important files and data, while allowing you to easily share files with family and friends. Featuring a compact pure white minimalist design, the TS-231K can easily integrate with any home décor and takes up very little space. The TS-231K comes with lockable drive trays, ensuring the drives will not be accidentally removed or fall out and cause data loss. The TS-231K provides comprehensive local, off-site and cloud backup and secure Snapshot technology to help create a reliable backup and disaster recovery plan. In the event of a system crash or accidental file deletion, you can quickly restore the system to its normal state. Quad-core CPU drives higher performance The TS-231K is powered by a quad-core 1.7 GHz CPU that features more CPU cores to enhance system performance. With 1 GB RAM, two Gigabit LAN ports, and SATA 6 Gb/s drives, the TS-231K delivers high performance, while also maintaining data security. The TS-231K also features three USB 3.2 Gen 1 ports, allowing you to transfer large media files between the NAS and your devices. The USB port on the front panel supports one touch copy, making it convenient for you to backup data on your external device to a NAS or vice versa with just one click. Easily Create a High-speed Network Environment You can use QNAP USB 3.2 Gen 1 on 5GbE adapters (QNA-UC5G1T) with the TS-231K or your computer. By connecting the NAS and PC through the 5GbE adapters, you can create a 5GbE network connectivity for nearly 300 MB/s transfer speed. Boost productivity with QNAP applications QNAP File Station provides centralized file management, allowing you to view and manage files on your TS-231K and other storage sources or external devices, which allows you to easily share files with family and friends through email, social media, or share link. You can also use Qfile mobile app to access NAS files from a mobile device. File Station File Station allows you manage files stored on your QNAP NAS in your cloud space, or from USB card reader and mobile devices. You can easily access all your data from a single application. Qfile Qfile mobile app allows you to access NAS files from a mobile device anytime anywhere, while uploading and backing up files on your phone to a NAS. Protects your sensitive data with file encryption When sharing sensitive or confidential files on your TS-231K, you can enhance data security with File Station by encrypting files into .qenc files and set a password. The file recipients need to download and install QENC Decrypter on their computers and enter the correct password to decrypt, view, and use encrypted .qenc files. Protect data against malware with Snapshots Snapshots help protect your data by fully recording the NAS system status and metadata. If a file is accidentally deleted or modified, you can use snapshots from the Storage & Snapshots Manager or the File Station to quickly restore files to its previously-recorded state. QNAP snapshots are block-based and only record changed data. Not only does this save storage space, but it also reduces time required to back up and restore data. The TS-231K supports up to 16 snapshots per volume/LUN, and up to 32 snapshots in total. Multi-point file backup, access, and sync HBS (Hybrid Backup Sync) consolidates data backup, recovery, and synchronization, allowing you to easily backup or sync data to another QNAP NAS, and remote server or cloud storage (e.g. Dropbox® or Google® Drive) to build a reliable disaster recovery solution. Qsync turns the TS-231K into a secure, high-capacity data center for file synchronization. Any file uploaded to the TS-231K will be made available for all linked devices, such as computers, laptops, and mobile devices. You can also sync shared folders or create team folders to enhance team collaboration. Windows/ Mac computer file backup QNAP NAS provides a simple solution for backing up/restoring laptops and desktops. You can use QNAP NetBak Replicator to backup files on Windows® computers, including Outlook® Email archive. The NAS also supports Time Machine® on Mac® devices, enabling easy, fast, and convenient data backup. Greater multimedia enjoyment The TS-231K comes with a wide range of media applications, including Photo Station, Video Station and Music Station, allowing you to easily manage and view your media files. You can also download Plex Media Server to turn your TS-231K into a multimedia server. Photo Station Features intuitive interface for you to arrange your photos by drag and drop. You can set access permission and can easily share photos to social media. By installing Qfile or Qphoto mobile apps on your mobile device, you can quickly upload your phone photos to TS-231K. Video Station A management tool for you to easily manage the videos on the TS-231K according to different categories from a single interface.
