Running SCSI drives in RAID in a NAS and transferring data over WiFi makes no sense. You will be limited by your WiFi speed no matter how fast the drives are in NAS.
In addition, this NAS does beg the question. What is wrong exactly with FreeNAS OS and a cheap Pentium III system with a $35 RAID card?
Modern business faces the challenge of dramatic growth of digital data, including documents, emails, applications, and so on. To deploy the IT environment with a reliable, affordable and expandable storage center to securely store, share, and back up the digital assets has become an important task for the server managers of the SMB and entry-level enterprise nowadays.
TS-439 Pro II+ houses up to four 3.5-inch or 2.5-inch SATA hard disk drives, incorporates Intel® Atom™ 1.8GHz single core processor and 1GB memory, and is capable of delivering ultra high performance, reliability, and lower power consumption during intensive data transfers. The NAS is an efficient and powerful business storage center with advanced iSCSI services, cross-platform data sharing, and all-in-one server applications. With VMware® Ready™ and Citrix® Ready™ certification, and proven compatibility with Microsoft Hyper-V environment, the NAS is an ideal shared storage solution in the virtualized and clustered environment.
Brand New Turbo NAS Series for Business
The Most Affordable and Flexible Virtualization Solution
TS-439 Pro II+ is certified as compatible with VMware® vSphere4 (ESX 4.0 and above) and Citrix® XenServer virtualization platforms, and is also compliant with Windows 2008 Failover Cluster. The NAS can be utilized as the network shared storage of VMware, Citrix virtualization environments and Windows clustered servers. Comparing with traditional SAN (Storage Area Network), the NAS is a competitive alternative with much lower setup and maintenance costs in an IP SAN.
Feature-rich and Integrated Applications for Business
The NAS supports file sharing across Windows, Mac, Linux, and UNIX platforms. Versatile business applications such as file server, FTP server, printer server, web server, and Windows AD (Active Directory) support are provided. The dominant features, such as WebDAV, Share Folder Aggregation (also known as DFS), IPv6 and IPv4 dual-stack, Wake on LAN, schedule power on/ off, HDD S.M.A.R.T, comprehensive log systems, and policy-based unauthorized IP blocking are all included.
New iSCSI for Virtualization Deployments
Turbo NAS provides flexible and secure storage server deployment with the following enhanced iSCSI features:
- NAS + iSCSI storage solution
Turbo NAS can serve as a NAS (network-attached storage) for file sharing and an iSCSI storage concurrently.
- Flexible multiple LUNs management
The NAS supports multiple LUNs (Logical Unit Numbers) and iSCSI targets. The LUNs can be flexibly mapped to, unmapped from, and switched among different iSCSI targets.
- Secure IP SAN environment deployment
Designed with CHAP authentication and LUN masking, the advanced ACL (Access Control List) offers you the capability to block the access from unauthorized initiators.
- Designed for virtualized and clustered environments
Comparing with the high cost of Fibre Channel SAN, Turbo NAS is an affordable system that can be deployed as a storage center for virtualized and clustered server environments, such as VMware, Citrix and Microsoft Windows Failover Cluster.

S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) helps you monitor the hard disk drives status. Moreover, Turbo NAS supports HHS (HDD Health Scan) for disk checking and bad blocks scanning.
The fan rotation speed is automatically adjusted according to the server's temperature. You can also define the system temperatures to trigger high speed or low speed fan rotation. By manually setting the fan rotation speed, the fan will rotate at the defined speed continuously.
Policy-based Automatic IP Blocking
To prevent the NAS from malicious attacks, you can create an IP filter policy to allow, deny, or auto-block the IP address or network domain which attempts to connect to the NAS via SSH/Telnet/HTTP(S)/FTP/Samba/AFP.
All the system event logs and connection logs can be saved to a remote Syslog server.
Detailed System Information
You can view the system status, such as CPU usage, total memory, free memory, packets received, packets sent, error packets, system up time, CPU temperature, system temperature, hard disk drive temperature, and system fan speed.
AES 256-bit Volume-based Data Encryption
The disk volume with AES 256-bit encryption can only be accessed by an authorized encryption password or key. This prevents the NAS data from unauthorized access and data breach even if the hard disk drives were stolen.
*The data encryption functions may not available in accordance to the legislative restrictions of some countries.
DOM Architecture and Fail-safe Dual OS
Two operating systems are built on the DOM of Turbo NAS for system booting alternatively upon every system startup. When one fails, the other one will be used to boot up the NAS, and the failed OS is recoverable from the other healthy OS.

*200,000 domain users and user groups can be imported according to QNAP's lab test.
Shared Folder Aggregation
You can easily access the share folders of other servers on Microsoft Networking through the "portal folder" on Turbo NAS. This saves your time and effort to login different servers one by one.
This feature allows multiple Turbo NAS servers on the same physical network to be protected by a single UPS via receiving UPS notification about abnormal power supply.
Web File Manager
Turbo NAS provides a web-based management interface Web File Manager for you to access and manage the server data anytime, anywhere by a web browser.
