It seems like we've been showered with mini-PCs of late, and Zotac is adding another couple to the pile—albeit with a unique twist. Each Zbox R can run a pair of 2.5" drives in RAID 0 or 1 configurations for extra performance or greater fault-tolerance.
The fancier of the two is the Zbox R1531. It features a Broadwell-based Core i3-5010U CPU with dual cores and quad threads clocked at 2.1GHz. Users can add up to 16GB of DDR3L-1600 memory via dual SO-DIMM slots. There's room for two 2.5" drives with SATA 6Gbps interfaces, plus a third mSATA drive. External I/O is provided by four USB 3.0 ports, a serial port, dual Gigabit Ethernet NICs, and 802.11ac Wi-Fi.
The more modest R1323 features the Celeron 2961Y, a dual-core Haswell chip clocked at 1.1GHz. It can also handle up to 16GB of RAM via two SO-DIMM slots, plus a pair of 2.5" drives, but it drops the R1531's mSATA slot. External I/O is identical to its fancier cousin.
Given the RAID capability and COM port, these Zboxes could be useful in industrial applications where fault-tolerance is required. But it might just be fun to gang a pair of SSDs together in a RAID 0, too. As with other Zboxes, Zotac will offer a Plus version of the R1531 with a 64GB mSATA SSD and 4GB of RAM pre-installed. The R1323 is only available as a barebones, though. Pricing and availability haven't been announced.
