W8900 The Definitive Windows Storage Server
  • Intel® Core™ i3-2120 3.30GHz Processor
  • Ultra-Fast SATA III and SAS 6G
  • HDMI Connectivity
  • Single-Instance Storage (Dedup)
  • No Windows Server CALs Required

    *The MS license needs to be purchased separately


  • Single-Instance Storage (Dedup)
    When data is sent to multiple users, single-instance storage allocates data to be stored once, eliminating the need to duplicate data storage. This results to reduced data storage and improved data backups. Single-instance storage is most functional when transferring data to large distribution directories by improved delivery efficiency.
  • No Windows Server CALs Required
    No CALs required benefits users the ability to access the services of the server without a permit. With this, business users will not have to go through the trouble of obtaining authorization of per-user or per-device. With no CALs required, users are able to access data on demand, without the troubles of CALs.
  • PCI-e Gen2
    The evolved PCI-e Gen2 offers innovative technology that saves cost with an efficient narrow configuration. While doubling the transfer rate of the previous PCI-e, the PCI-e Gen2 provides the same bandwidth as the PCI-e but with only half its lanes. The target is to save on cost and provide an improved PCI-e for users. The Gen2 provides a significant improvement on system performance over the PCI-e; users can now enjoy faster transfer speeds and connectivity.
  • HDMI Output
    Make your NAS into the ultimate multimedia hub! The W8900's HDMI output allows you to connect your NAS directly to your TV for device management.

  • 10GbE Ready
    High-end data centers often need a level of speed that today's average Internet cannot provide. This Thecus NAS is 10Gb Ethernet ready to satisfy the toughest needs of today and tomorrow.

  • USB 3.0 Connectivity
    The next generation of connectivity is here with speeds 10x faster than USB 2.0. Whether connecting digital cameras and smart phones, backing up large external hard drives, or extending the capacity of your NAS, USB 3.0 will make sure it's done in no time at up to 5 Gbit/s. Backwards compatibility adds the connectivity of a world full of USB 2.0 and USB 1.1 devices to get the best combination of speed and universal access.


Thecus has received hundreds of awards during its history for its innovative and reliable hardware, helping countless people all over the world to share our new digital-era treasure: data. Thecus believes in diversity. That's why they are releasing a new Windows Storage Server-powered NAS product line to help you share your files using Windows Storage Server 2012: the W Series. Three models will be available: 8-bay W8900, 12-bay W12000 and 16-bay W16000.

“The release of the W Series is the start of a very fruitful relationship with Microsoft that will help us achieve our main goal: to satisfy more and more Thecus users with high-quality network appliances,” says Florence Shih, General Manager of Thecus Technology.
