Proactive Data Protection
QNAP SMART Data Migration
The data stored on the Turbo NAS is constantly monitored to reduce potential data loss and rebuilding time. If the Turbo NAS detects a possible drive failure or abnormal health status, the data will be proactively migrated to a new spare drive. This ensures valuable business assets are well stored and protected.
Supports TLER and ERC
TLER (Time-Limited Error Recovery) and ERC (Error Recovery Control) are now supported with compatible hard drives, improving drive error handling in RAID applications. This latter prevents the hard drives from prematurely failing out of RAID arrays, forcing rebuilds, and RAID volume loss. The data will be retrieved more quickly when a hard drive takes too long to respond from bad blocks.
RAID Read Error Recovery
When read errors are detected in the hard drive blocks, they are automatically corrected with healthy ones. The bad block recovery will run in the background and ensure data is well stored in the hard drives.
RAID Hot-spare and Global Hot-spare Drives
A hot spare drive can be configured so that if a hard drive in a specific RAID group fails, the hot spare drive will operate automatically. Moreover, the QNAP storage also supports global hot spare drives which allow the administrator to share the spare drives efficiently among multiple RAID Groups.

The Turbo NAS supports remote login by SSH (secure shell) or Telnet connection.
|SSL Security (HTTPS)
The Turbo NAS supports HTTPS. Users can upload a secure certificate and RSA private key in X.509PEM format issued by a trusted provider to allow access the Turbo NAS by secure SSL login.
The Turbo NAS offers secure data transfer with SSL/TLS (explicit) encryption. Passive FTP port range setup is also supported.
|Encrypted Remote Replication by Rsync
The data on the Turbo NAS can be backed up to or from another Turbo NAS or rsync server over the network securely.
|FIPS 140-2 Validated AES 256-bit Volume-based Data Encryption
The disk volume with FIPS 140-2 validated AES 256-bit encryption can only be accessed by an authorised encryption password or key. This prevents sensitive data on the Turbo NAS from unauthorised access, even if the hard disk drives or the entire system were stolen.

The integrated antivirus solution for the Turbo NAS ensures business continuity by offering detection against the latest viruses, malware, worms, and Trojan horses with continuous free virus database updates.
QNAP Flexible Volume
QNAP Flexible Volume provides a more secure and flexible way to store and manage the NAS data. This next generation volume offers powerful features such as storage pooling with multiple RAID, thin-provisioned volume with space reclaim, and online capacity expansion.
Block-based iSCSI LUN
In addition to storing data, the QNAP Flexible Volume can be utilized as an iSCSI LUN at the same time. The block-based iSCSI LUN provides less overhead which improves the overall read/write performance. The blockbased iSCSI LUN takes advantage of Flexible Volume features such as thin provisioning LUN with Space Reclaim and online capacity expansion.
Online Capacity Expansion
Increase the capacity size of the LUNs, volumes, and storage pools on the fly. The Turbo NAS allows you to add more hard drives to increase the storage capacity of the storage pool on demand. The LUN and volumes can also be expanded online without interrupting the services.
Pre-allocate storage to give the appearance of having more capacity than actually available. This allows you to consume storage on demand as data is written to disk, instead of having capacity ahead of time.
Space reclaim complements thin provisioning so storage can be recovered and used for other NAS applications. Normally when data is deleted in a volume the storage capacity cannot be transferred back to the overall storage pool. But with space reclaim, space can be recovered and allocated back to the overall storage pool. This provides a much more efficient space usage.
Alert for Volume/LUN Threshold
An alert can be created once a LUN or volume reaches a particular threshold size with email and SMS notifications. This prevents the storage or volume from running out of space, and the administrator can add more storage space or expand an existing volume if necessary.
Powerful, organized, rich-in-content
The new App Center makes it easy to find and install all sorts of apps and also acts as a central platform to manage and update your installed apps.
Mobility and Remote Access

It allows you to remove files on one computer without affecting the copies stored on others that are linked with the Turbo NAS. However, when someone updates the files you deleted from another computer, you can still retrieve them in the Qsync folder.
Advanced Selective Sync
With both Full Sync or Smart Sync options, you can choose to only sync specific sub-folders within the Qsync folder, useful if your computers have limited storage.
Share files and folders easily
Quickly share files with download links

Share folders for collaboration
Your life is connected with different groups of people. You can create sub-folders within the Qsync folder, and share each with different groups of Turbo NAS users as a file exchange center. Everyone in the same sub-folder is always kept up-to-date with the latest version of the files.
