NAS between Rs.40,000 - Rs.80,000

QNAP
TS 459 Pro
This 4-bay model packed with Intel Atom D510 1.66 GHz dual core processor coupled with 1 GB RAM is meant to deliver performance, and the score that it got for performance tests confirms that. TS 459 Pro match the performance and feature scores of the category winner Thecus N550, but is left behind on the price front, and thus stands second. This box is ideal for organizations as it is just not a storage server but with the features that are included with it can work as an all-in-one server. Besides storing files on network share, the QNAP TS 459 Pro can be also used as print server, web server, database server, media streaming server and also as an IP surveillance station that can support upto 4 IP cameras.
The front panel has 16x2 LCD screen and through menu buttons you can configure the NAS without connecting to a PC. It even allows you to choose RAID mode which other NAS devices lack, as on them RAID mode has to be selected from web interface.
The TS 459 Pro does the core job as a NAS exceptionally well, in addition it's the bundled features that make the product your money's worth.

Thecus N5500
The deserving winner of the category, Thecus N5500 not only scores best in performance and features, but also is the lowest priced model. Thecus N5500 is equipped with five hot-swappable HDD bays that can offer you an option of upto 10TB of total storage capacity. The unique feature that catches the eye is dual-DOM, which provides extra level of fault tolerance. DOM (Disk on Module) is flash memory based interface that runs an embedded operating system which is used to boot the device. The idea to have two DOM is that if one fails the other takes over, without giving any down-time or unexpected system failures.
The N5500 offers a good specification with an Intel Celeron M processor that delivers higher computing power and is coupled with 1 GB of DDR II memory. The N5500 also supports multiple RAID volumes, enabling you to choose the right combination of RAID volumes for your network. The N5500 can also be used as iSCSI unit, as it supports iSCSI initiators. The device is also stackable, allowing you to control multiple N5500 units from one master system for added flexibility. N5500 can also be configured as a surveillance system and it can support upto 20 IP cameras.

Seagate BlackArmor NAS 440 4TB
Seagate BA NAS 440 put us in a tricky situation. The NAS's 'setup wizard' page that asks to change the device name, device description and time. The 'Next' button on that page does not work, and the browser status bar displays script error. This hampered us from setting up the IP, selecting the RAID 0 mode and other activities like upgrading the device's firmware, since the setup wizard didn't allow us to proceed. After going through Seagate forums online (http://bit.ly/b5D3IP) we found that BA NAS 440 accepts only '2008-01-01' as date and then only proceeds further. Doing so resolved the issue.
The Seagate BA NAS 440 was shipped with four 1TB drives and boasts of features like support for multiple RAID configurations, DLNA media server and remote web access. The device is ideal for catering to workgroups of size upto 50 workstations. The two Gigabit Ethernet ports can be used either for port failover or for NAS to NAS replication. While the USB ports can be used to connect external storage drives for capacity expansion or for backup purposes.
