Breakthrough performance The TS-EC1680U R2 supports 6Gbps hard drives driving over 3,500 MB/s throughput and 390,000 IOPS. Featuring with Intel® Xeon® E3 v3 Quad-Core Processor and 4 GB DDR3 ECC RAM, the TS-EC1680U R2 greatly enhances efficiency of CPU-consuming tasks and serves more concurrent tasks at the same time. Internal cache port for IO acceleration The TS-EC1680U R2 supports two on-board mSATA internal cache ports, and up to 4 SSDs can be used for caching. By installing mSATA flash modules (optional purchase), the IOPS performance of storage volumes can remarkably boost. It is perfect for improving overall workflow of random IOPS demanding applications such as database and virtualization. The internal cache port design reserves the space of hard drive tray for more storage capacity. Removable motherboard drawer for easy maintenance With the TS-EC1680U R2''s removable motherboard drawer, IT administrators have easier access in upgrading/installing components such as RAM, the internal cache and 10GbE adapter. The motherboard itself can be removed and replaced without needing to remove the heavy TS-EC1680U R2 from the rack cabinet, making it especially useful in maintaining the TS-EC1680U R2 in data centers with multiple rack cabinets.
