Robust and Protected: Welcome to Buffalo Hardware Raid

RAID CPU will help your data transaction faster and more stable


Since WSH5610DNS6 has dedicated a hardware RAID CPU; the system CPU has less workload for RAID-building and maintenance, thus securing a more stable performance on the device, and leaves more power for the main CPU to run apps and share files.


Benefit of having dedicated CPU for RAID *1                                                                                                                                                          

















Performance under heavy workload *2













More redundant RAID 6 is available with Windows Storage Server

RAID redundancy is highly recommended for your business data protection, and Windows Storage Server OS provides RAID 5.

With Buffalo’s original hardware RAID CPU, your data on the WSH5610 can be secured using RAID 6, which is more redundant than the default options.

Since the cache is secured exclusively, it is possible to minimize the risk of data corruption even if the OS freezes.


*1 Test Environment (August 2017)
[Backup] From BIOS Inc. MX 404N312 (NAS) To WSH5610DNS6 or WS5600DN
Connect WSH5610DNS6 and MX404 under the same LAN, and setup as network drive. First install Trend Micro Virus Buster XG, then run backup 1TB data (52x 19GB movie files) with Arcserve Backup
*2 Test Environment (August 2017)
[PC] CPU: Intel (R) Core (TM) i7 4771 @ 3.50 GHz, Memory: 32 GB, NIC: Intel Gigabit CT Desktop, OS: Windows Server 2012 R2 64bit
[NAS] WSH 5610DNS6 or WS5600DN (Format with RAID 5 with NTFS, create shared directory)
With the NAS and the PC directly connected to the LAN, set the shared directory of the NAS to the network drive of the PC. Measured the performance of sequential write speed on benchmark software (CrystalDiskMark 5) of normal operation and of RAID rebuild after exchanging one HDD. (average of 10 measurements)

Buffalo also offers optional Next Business Day/Keep Your Drive warranty options. Warranties can be extended up to 5 years 
(Warranty Service).


 - Purpose build & optimized for data storage


The NAS hardware is built with business class components to provide stable 24/7 operations, including Intel Quad core CPU with 8GB memory to stabilize the performance.








Quick boot and efficient data storage with OS data on SSD



Since Windows Storage Server OS is mounted on and operates from the SSD, device bootup is 63% faster. 

Typical Windows Storage Server NAS has the OS data on HDDs with the partition, which will reduce the usable data area.

WSH561DNS6 has separate SSD just for OS data storage. You can use all the HDD capacity for your business data storage and incur no hassle if you need to change the RAID mode later.
