The Penta SATA HAT utilizes the M.2/PCIe interface on RADXA´s ROCK Boards* to provide up to 5 SATA ports. This HAT works only with Rock Pi 4 mounted on the heat sink.

The concept of 4 internal SATA and one eSATAp design was chosen because it makes the setup more flexible for the use of external disks.


  • Up to 5x HDD/SSD, 2.5inch and 3.5inch storage is supported, max storage 100TB
  • 4x SATA
  • 1x eSATA with power
  • utilizes two lanes of the PCIe 2.1 bus on Rock Pi 4
  • DC power input with support for both 2.5inch drives and ROCK Pi 4
  • External standard ATX power supply support for 3.5inch HDD
  • HDD suspend mode support
  • Software RAID 0/1/5 support
  • Optional PWM control fan for HDD heat management
  • Optional OLED display for IP / Store information
  • PLEASE NOTE: You need to order the heat-sink with Rock 4, otherwise the Penta HAT can not be mounted on top. For use with Rock 3A please purchase the base plate for proper installation.


To fully take advantage of the 5th SATA port, an eSATA connector was implemented which can be exported e.g. out of the case. The eSATA connector provides both data and power. It can directly drive a 3.5inch HDD via a single cable.


The Penta SATA HAT is powered by the JMB585 with 2 lanes 5Gbs PCIe buses with up to 10Gbps bandwidth. With 5 SSD's configured in Raid0 mode, speed of up to 803MB/s can be achieved.

Purchasing & Delivery

You may be liable for import duties, sales tax, or customs processing fees. It's your responsibility to ensure you're fully aware of the local requirements for importing goods from China to your location. We cannot offer any refunds due to unexpected charges applied locally. We are required to include a commercial invoice with all shipments.


Since July 1st, 2020 EU buyers are obliged to pay local VAT on all orders shipped. The previously VAT free value of up to €22 has been cancelled. Instead there is a new regulation for goods imported to the EU for values up to €150. (i.e. not subject to excise duties)

Because ALLNET China is not able to pre-collect the related VAT on the checkout yet, you will be contacted directly when the parcel arrives in your country and asked to pay the outstanding amount.

After that the parcel will be delivered to you like before. We work on a solution to make this more convenient for you and hope to present it to you soon.

IMPORTANT NOTICE! If the requested payments from the EU tax authorities are not balanced, the parcels will be either destroyed or returned to us. In this case we unfortunately can not refund both shipment cost and product price. The return process creates high cost on administration, shipment and re-import which have to be covered.
