The QNAP TS-412U Turbo NAS is a 4-drive 1U rack-mounted network attached storage (NAS) server optimized for small and medium business who are looking an affordable yet high performance network storage solution. The TS-412U is easily installed in the server room and configured for up to 12TB (using 3TB hard drive) of online storage. The TS-412U is an ideal solution for centralized data backup, cross-platform file sharing, website hosting, and much more. Moreover, the TS-412U offers exceptionally low power consumption, maximum system reliability & expandability, and numerous business-critical applications.

The TS-412U incorporates an embedded Marvell 1.2GHz CPU and 256MB DDRII memory, delivering high speed throughput. It works with 2.5-inch or 3.5-inch SATA hard drives mounted in hot-swappable drive carriers and includes two Gigabit LAN ports for multi-IP settings and port trunking (7 bonding modes). Also, it is equipped with 4 USB ports and 2 eSATA ports for storage expansion or external data backup.

In addition, the TS-412U supports NAS and iSCSI applications to provide a low-cost, highly flexible and efficient IP SAN solution for SMB users. iSCSI targets can be created on the NAS for storage expansion of the PC or other servers and backup destination of the database servers and mail servers, etc. The TS-412U can be used to connect to other iSCSI devices on the network and add them as virtual disk drives (VDD) to expand the storage capacity of the NAS.

  • newegg Feature-rich and Integrated Applications for Business The TS-412U supports abundant powerful applications which can be accessed across Windows, Mac, Linux, and UNIX. Also, numerous management tools, such as Windows Active Directory (AD), real-time system monitoring, detailed event logs, Simple Network Management Protocol (SNMP), instant SMS alert, Wake on LAN, and scheduled power on/off management are provided for the users to manage the NAS efficiently.
  • newegg Advanced RAID Management with Hot-swap Design Turbo NAS offers RAID 0, 1, 5, 6, 10, 5 + hot spare, single, and JBOD disk configurations. The unique online RAID capacity expansion and online RAID level migration allow the users to expand the storage capacity of the RAID configuration and upgrade the RAID level without turning off the server respectively. The RAID recovery feature secures the server data against accidental removal of the hard drives. Turbo NAS also supports hot-swap design that a failed member drive of a RAID configuration (RAID 1 or above only) can be replaced by hot swapping without turning off the server.
  • newegg Storage Expansion by Virtual Disk Drive (VDD) The NAS supports flexible storage expansion by stacking other iSCSI targets on the network via its built-in iSCSI initiator. The connected iSCSI targets are turned into "virtual disk drives" of the NAS to provide more storage capacity.
  • newegg Built-in iSCSI/IP-SAN Target Service The TS-412U is both a NAS and an iSCSI target server, ideal for cost-efficient IP-SAN setup. You can make use of the built-in iSCSI target service to add up to 256 iSCSI devices. Different iSCSI Target LUNs (Logical Unit Number) can be defined as storage expansion or backup destination of the existing application servers, such as database servers and mail servers. Furthermore, the "Virtual Space Allocation" (Thin Provisioning) feature is provided which allows you to flexibly allocate the capacity of iSCSI LUN (Logical Unit Number). When the physical storage capacity of the volume is going to be full, you can easily expand the storage capacity by online RAID capacity expansion or adjust/ remove the current unused volume space.
  • newegg Superior Performance and Energy-saving Design The NAS delivers superior performance and high reliability for critical business applications. It is optimized to achieve low noise and low power consumption for environment protection.
  • newegg Complete Data Backup Solution The NAS offers complete backup solution for data protection, including cloud-based storage backup (Amazon S3, ElephantDrive), Apple Time Machine support, encrypted remote replication, third party software backup, one-touch-copy backup and QNAP exclusive Windows-based utility NetBak Replicator.

2 out of 5 eggsJust not worth it

Pros: Web interface is well-designed and really easy to use. There are a lot of compelling features on this device.

Cons: We have 3 QNAP devices, two of these and one of a higher model, and they are hands down the worst purchase decision we ever made. They frequently mark drives as "Read/Write Error". There's nothing really wrong with the drivers, but you have to pull them out and run the drive manufacturer's fix and erase tools, then you have to put the drives back in and wait three-four days for them to rebuild. Then about a month later, a different drive will have the same issue. This is if you're lucky. If you're not lucky, putting the drive back in will cause the unit to panic and mark the entire array as "unknown". Just accept that your data is lost at that point. Trying anything else will probably result in the device being completely blown out and you doing a complicated firmware restore procedure.

Other Thoughts: I'm not sure who else is in the market at this price point, but do yourself a favor and find out who they are.
