Radxa is very happy to announce the ROCK Pi SATA HAT, a series of SATA expansion targeting at the NAS solution for Raspberry Pi 4 and ROCK Pi 4. The ROCK Pi SATA HATs come in 3 models:
- Dual/Quad SATA HAT
- Penta SATA HAT
The Dual/Quad SATA HAT is designed for Raspberry Pi 4 as well as ROCK Pi 4, and the Penta SATA HAT is designed for ROCK Pi 4 only.
Dual/Quad SATA HAT
The Dual/Quad SATA HAT utilize the USB3 buses on Raspberry Pi 4 or ROCK Pi 4, it has the following features:
- Up to 4x HDD/SSD, support 2.5inch or 3.5inch SSD
- Utilize two independent USB3 buses on Raspberry Pi 4
- Type C power input with USB PD/QC support for both 2.5inch SSD and Raspberry Pi 4
- External standard ATX power supply support for 3.5inch HDD
- Fan and heatsink for Raspberry Pi 4 CPU cooling
- Support HDD suspend mode
- Support UASP
- Support software RAID 0/1/5
- Optional PWM control fan for HDD heat dispatching
- Optional OLED display for IP Address/Storage info
For 3.5 inch HDD, a standard ATX PSU is required to power the HDD and the Raspberry PI itself. With 4 3.5inch HDDs, the PSU should be 60W or more.
For 2.5 inch HDDs, you can just use the USB PD/QC power adapter(30W power adapter is enough) to power the HDD/SSD and the Raspberry Pi 4 itself.
Performance
Quad SATA HAT utilizes two high performance JMS561(one JMS561 for Dual SATA HAT) providing up to 400MB/s reading/writing performance with four disks in RAID0 mode.
