Over the past couple of years, we've seen a lot of new entries into the NAS market and another new player is Zettlab. The company ran a successful Kickstarter campaign, raising over US$1.48 million from 1820 backers. The company brought base tier D4 and D6 models to CES and these models have started to arrive with its backers about six months late, whereas the more powerful Ultra models seem to have ended up stuck in development hell, partially due to increased DRAM prices.

The D4 and D6 are based on the Rockchip RK3588 Arm SoC with four Cortex-A76 and four Cortex-A55 CPU cores, a 6 TOPS NPU and an Arm Mali G610 MC4 GPU. Zettlab has paired the RK3588 with 16 GB of LPDDR4x memory and 32 GB eMMC for the OS. Both SKUs have a 1 Gbps and a 2.5 Gbps Ethernet port, one NVMe slot, and HDMI port, one Type-C and one Type-A USB 3.0 port, two USB 2.0 ports, one full-size SD card slot and one microSD card slot, as well as a 3.49-inch information display around the front. As the model name suggests, the D4 has four 3.5-inch drive bays and the D6 has six. Zettlab provides its own ZettOS which is said to be an AI first OS and the company was demoing its ZettAI at CES, but outside of that, it seems like ZettOS is a fairly basic NAS OS at the moment.
