"Like the TS-639 Pro and TS-439 Pro, the TS-239 Pro is equipped with a 1.6GHz Atom N270, matched with an Intel 945GSE + ICH7M chipset. It likewise offers 1GB DDRII memory, as well as a 128MB "disk-on-module" (DOM). Qnap claims that NetBench test results show 350MBit/s of throughput when 20 clients are accessing the TS-239 Pro simultaneously.
"The device offers two trays, each of which can hold up to 2TB capacity, for 4TB total of hot-swappable storage, says Qnap. The TS-239 Pro is said to provide three USB 2.0 ports and two eSATA ports for external storage and backup. The system's dual gigabit Ethernet ports can be configured as failover, load balancing, or serving two different subnets, says the company. Like its other Atom-based siblings, the TS-239 features a redesigned chassis with vertical drive orientation, for cooler operation."
