There are many platforms for network-attached storage, but FreeNAS is renowned for being free, open-source, secure, and scalable. It is incredibly versatile, allowing you to create media streaming servers, virtualization servers, and multi-site backup systems. However, is it different from TrueNAS? Should you use FreeNAS vs TrueNAS? FreeNAS is a legacy NAS platform that has rebranded into TrueNAS CORE. TrueNAS CORE has faster OpenZFS performance, better security, and more developer support than FreeNAS, but their source code is still 95% similar. Businesses and hybrid cloud users also benefit from new features in TrueNAS Enterprise and TrueNAS SCALE. What is FreeNAS? FreeNAS is an open-source network-attached storage platform initially developed by Olivier Cochard-Labbé in 2005. It is based on FreeBSD and features an OpenZFS file system, RAID controller, and volume manager. Home and office networks can also easily share files between Windows, Linux, and macOS! With its plug-in architecture, you can stream all kinds of data from any connected device. For example, FreeNAS integrates with Plex to provide media streaming. There are many third-party plug-ins available to install, including: PlexGitLabBaculaGamezBTSyncBitTorrentCouchpotatoHTPC-ManagerMarachinoEmby As of October 2020, iXsystems has unified FreeNAS with the TrueNAS product line. It is now known as TrueNAS CORE, and it continually receives software updates. Features OpenZFS File System Developed by Sun Microsystems, OpenZFS is a scalable, open-source storage platform that combines a filesystem and volume manager. It features limitless SSD/HDD capacity, data corruption safeguards, fast data compression, RAID-Z support, remote replication, and automatic repair. FreeNAS has access to all these features, including RAID 1+0 data redundancy via striping, mirroring, and striped mirroring. Data Compression and Deduplication FreeNAS automatically increases storage capacity and performance using block-level data compression and deduplication. Compression reduces file sizes, and deduplication removes identical data. However, pre-compressed data, such as video, are left safely untouched. Encryption FreeNAS supports Self-Encrypting Drive (SED), providing password protection to storage devices. Unless unlocked, data remains unreadable and uncopyable when disks are removed or shut off. However, encryption does not extend to data in transit. Snapshots and Replication Snapshots preserve old versions of data for recovery, similar to Windows System Restore. If data or a filesystem version corrupts, they can return to a previously saved point. You can schedule, request, and manage snapshots via the FreeNAS Web interface. Replication duplicates snapshots to other compatible ZFS file systems on a scheduled or ongoing basis. Data is still secure on a replicated snapshot from another disk if the primary storage disk fails, especially during disaster recovery. What Can You Use FreeNAS For? FreeNAS is mainly used as a free file storage solution for NAS devices. With its secure ZFS file system, you can build enterprise-grade storage with striped drives, mirrored drives, and two parity drives. The FreeNAS operating system is so versatile that you can also use it for: Media streaming serverTorrent serverVirtualization serverBackupsHome automationPersonal cloud storageAdblockerVideo game library What is TrueNAS? TrueNAS is a set of open-source NAS operating systems developed by iXsystems, such as TrueNAS CORE, TrueNAS Enterprise, and TrueNAS SCALE. All platforms are based on FreeBSD, Linux, and the OpenZFS file system. It features virtualization with various protocols, full-disk encryption, and a plug-in architecture. TrueNAS CORE TrueNAS CORE, formerly FreeNAS, is the world’s most popular storage OS. Users can safely store, share, and manage data across connected SSDs, HDDs, and servers – all for free. It even supports the latest hardware, such as high core-count AMD processors and NVMe SSDs. CORE stands for community-supported, open-source, rapid development, and early availability. These principles guide future updates to main features, including encryption, RAID support, data recovery, data redundancy, and virtualization. TrueNAS Enterprise TrueNAS Enterprise is a storage solution for businesses with mission-critical uses. It provides 24/7 uptime, single or dual controllers for High Availability, support services, and core TrueNAS features. Businesses can configure TrueNAS Enterprise with various storage systems, such as TrueNAS M-Series, X-Series, and R-Series appliances. With up to 10 GB/S of bandwidth and 10 petabytes of capacity, enterprise data needs can quickly scale. TrueNAS SCALE TrueNAS SCALE is a Linux-based storage platform built on hyper-converged infrastructure, allowing storage and computing to scale independently. It adds Linux Containers, kernel-based virtual machines, and scale-out ZFS features for improved IT efficiency and scaling. SCALE stands for scale-out, convergence, active-active, Linux, and easy. These goals optimize TrueNAS SCALE for hybrid cloud systems, combining virtual machines and container-based applications. TrueNAS vs FreeNAS Differences FreeNAS has been considered legacy software since its final 11.3-U5 update. It has since transitioned into TrueNAS CORE, receiving software updates and new features. Both are free, but the latest TrueNAS is faster, more stable, and more flexible than the discontinued FreeNAS. Enterprise Integration FreeNAS was only community-supported, so businesses had to use TrueNAS for critical enterprise storage. After FreeNAS became TrueNAS CORE, users could access the enterprise platform within the same software with a license key. Enterprise features include Fibre Channel, High Availability, KMIP, and Enclosure Management. It also comes with TrueNAS Enterprise quality assurance, testing, and support services. OpenZFS Performance TrueNAS uses the multi-OS version of OpenZFS 2.0, replacing the FreeBSD version. OpenZFS 2.0 exclusively offers Fusion Pools and special VDEVs, while improving overall performance and virtualization. Larger TrueNAS configurations, such as the TrueNAS M60, can gain up to a 30% performance boost! Security Since FreeNAS is no longer supported, it is vulnerable to security weaknesses. With the adoption of FreeBSD 12.1 and SAMBA 4.12, TrueNAS patches old exploits and adds KMIP, ZFS dataset-level encryption, and OpenVPN integrations. You can protect your data and IT infrastructure by staying updated with the latest TrueNAS security vulnerabilities. Cloud Management With Cloud Sync Tasks, TrueNAS can send, receive, and synchronize data with third-party cloud storage providers, such as Amazon S3 or Google Cloud. TrueCommand Cloud also makes it convenient to back up and manage data between multiple sites. To view all TrueNAS-supported cloud storage vendors, navigate to System, select Cloud Credentials, and open the Provider dropdown menu. Whichever provider you choose, TrueCommand 2.0 will collect comprehensive statistics to improve cloud management practices.
