"So today we tested an extremely high-quality product. Despite some minor shortcomings, the Thecus 1U4600R left a very positive impression. It has excellent and thoughtful functionality, full data protection, easy management, and good performance."

Media: IT Expert | Country: Russia

"To summarize the above said, Thecus 1U4600R delivers every necessary feature for secure data storage. Its ultimate reliability is ensured by a Dual DOM design, redundant power supply, load balancing and flexible backup copy features."


  • Ultimate Performance with Intel® Celeron™ Technology
    Enterprises simply cannot afford to wait for their data, which is why the 1U4600 is built for speed. Featuring Intel Celeron Technology, the 1U4600 comes equipped to handle multiple client access and deliver quick system response and increased data throughput.
  • Built-in Cloud Networking
    For cloud computing applications, the 1U4600 offers easy multiple system management with Cloud Networking. This feature enables administrators to manage multiple 1U4600s via a single master system, simplifying administration and saving time in the process. No more having to configure storage devices one at a time - the 1U4600 makes it easy.
  • Three Storage Systems in One
    With the 1U4600, businesses are getting three devices in one: a NAS, a DAS, and an iSCSI device. Choose the right mode for your organization and experience the flexibility of the Thecus 1U4600.
  • Signature Dual DOM™ Design
    A Disk On Module (DOM) contains all of the system's critical software. If it stops working for any reason, your system firmware could be inaccessible - or worse. With the 1U4600's Dual DOM™ Design, a secondary DOM automatically reprograms the primary DOM if it fails, meaning your data is always safe and accessible. 
  • Online RAID Volume Management
    Managing RAID volumes has never been easier thanks to the 1U4600's Online RAID Volume Management. Administrators can easily expand or migrate RAID volumes without having to power down the system, eliminating costly downtime.


Two short years ago, Thecus® Technology shook up the world of enterprise storage with the release of the 1U4500 – a rackmount storage server which utilized SATA technology. Today, Thecus® is pleased to announce a follow up to this groundbreaking device: the 1U4600 Rackmount NAS Server. Offering increased system performance and complete security and flexibility, the 1U4600 is an excellent storage solution for the growing enterprise.

Business users need to access data as quickly as possible, which is why the 1U4600 is built for speed. Powered by Intel® Celeron technology and 1GB of DDR memory, the 1U4600 delivers tremendous data transfer performance and quick system response even with multiple client access. For organizations that require cloud computing applications, the 1U4600 fits the bill nicely with its cloud networking ability. This feature allows multiple 1U4600 units to be accessed by a master system, forming a huge data pool. Being a Thecus® product, data security is also top-notch, featuring multiple RAID modes, including RAID 0, 1, 5, 6, 10 and JBOD. Best of all, administrators can take advantage of online-RAID volume management to handle such tasks as RAID expansion or migration with zero downtime.

But the 1U4600 is also incredibly flexible. For starters, it can be used in NAS, DAS, or iSCSI mode, depending on the needs of the organization. To keep things running smoothly, the 1U4600 is built with a dual DOM design, which enables the main system DOM to be reprogrammed by a secondary DOM should it fail for any reason. And to guard against sudden power supply failure, power redundancy is also available with the 1U4600R, which packs a 250W redundant power supply for uninterrupted service.

“Enterprises need superior storage at a price that fits within budget, and the newly updated 1U4600 meets these requirements,” said Florence Shih, Thecus General Manager. “With multiple redundancies and superior performance built-in, the 1U4600 sets the new standard in powerful yet versatile enterprise storage.”
