QNAP NAS Applications for Business Users
High Performance, High Reliability, and Disaster-proof
NAS Server
The Most Advanced RAID Management:
To ensure the data security, TS-409 Series offers advanced disk congurations for RAID 0/ 1/ 5/ 6, 5 + Spare, Single, and
JBOD. (RAID 6 is rarely provided in the same class of NAS server.) TS-409 Series' RAID 6 and RAID 5 even allow one more
hard drive failure than other NAS of the same level. Therefore, when 2 drives fail in RAID 5 or 3 drives fail in RAID 6, TS-409
Series will enter read-only protection mode, and users can still rescue their critical data. This effectively lowers down the risk
of data loss caused by failure of hard disks.
Online RAID Capacity Expansion and Online RAID Level Migration:
With Online RAID Capacity Expansion, users can select to purchase the most
cost-effective hard drives for initial server setup and upgrade to larger ones in
the future. All the stored data will be kept and seamlessly moved to the newly
installed hard drives. There is no need to turn off the server during the process.
With Online RAID Level Migration, users can start from one drive firstly and
add more drive members to upgrade the RAID level in the future with the data
retained. There is no need to turn off the server during the process.

In e-business times, enterprise users need a trust-worthy NAS
as a data storage center. The NAS is accessible by all kinds
of OS users (Windows, Mac, Linux, and Unix). Windows AD
support saves server manager's time and effort in access
control, and also lowers the maintenance cost by centralized
management.
