The Raspberry Pi 4 Model B computer has been released in July.

We have got many emails about how to add the SSD or HDD storage to the newest Raspberry Pi Model B.

1. Will the X820 2.5 inch SATA HDD/SSD Storage Expansion Board Compatible with Raspberry Pi 4B?

The answer is no, we release a updated version of Raspberry Pi 4B which we call it X825 2.5 inch SATA HDD/SSD Storage Expansion Board.

2. Will the X850 mSATA SSD Storage Expansion BoardCompatible with Raspberry Pi 4B?

The answer is no, we release a updated version for Raspberry Pi 4B which we can it X855 mSATA Storage Expansion Board.

3. Will the X830 V2.0 Safe Shutdown 3.5 inch SATA HDD 12V Storage Expansion Board Compatible with Raspberry Pi 4B?

Actually the USB connector is not right one for Pi 4, but you can replace the USB connector with the Blue USB cable to have a try. Also it will be updated to X835 new model in the future..

X825: Raspberry Pi 4 Model B 2.5 inch SATA HDD/SSD Expansion Board X825 V1.2 USB3.1 Shield Compatible with Raspberry Pi 4B Only

The X825 expansion board provides a complete storage solution for newest Raspberry Pi 4 Model B, it supports up to 4TB 2.5-inch SATA hard disk drives (HDD) / solid-state drive (SSD). Only 2.5 inch SATA interface HDD/SDD hard disk is suitable for X825 Board;
It is updated from Raspberry Pi 3B+/3B X820 V3.0 2.5 inch SATA SSD expansion board. (Please refer to X820 if you want use the 2.5 inch SATA SSD on raspberry pi 3b+/3b/2b)

Key Features

• Supports upto 4TB 2.5-inch SATA hard disk drives (HDD) / solid-state drive (SSD) (Theoretically it can work with 6TB or 8TB as well. But actually we do not test the X825 board with 6tb or 8tb HDD, you can have a try.)
• Ideal storage solution for Raspberry Pi 4 Model B
• On-board push button to control power on /off (Press-ON, Hold the button pressed at least 2s -OFF)
• Powers the Raspberry Pi via Pi's 40-pin header
• LED red indicator indicates powered status and blue indicator indicates drive status
• USB 3.1 Gen1 to SATA 6Gb/s Bridge Controller
• Quick file transfer with high-speed USB 3.1 connectivity from a PC or a Mac
• Powers the Raspberry Pi - no additional power supply for RPi 4

Power Supply

• Power supply: AC 100 - 240V input 50 / 60Hz, 5V DC 4A output
• DC Power Plug Size : 5.5*2.5mm
• Important Note: Please use high quality DC 5V 4A power supply, the best choice is to buy the DC 5V 4A power supply that Geekworm provided. If you get low quality power supply to use, it may probably will damage your 2.5 inch HDD/SSD.

Match Metal Case
A metal case with power control switch and super mute cooling fan, it is a perfect choice for X825 V1.2 SSD/HDD storage board user. It also support to install the X735 Auto Cooling & safe shutdown board over Raspberry Pi 4. We call it honeycomb chassis. Also it updated to support Max 15MM thickness big capacity 2.5 inch SATA HDD/SSD

Note: Because we found that USB 3.0 high-speed transmission will interfere with the Raspberry Pi's 2.4G wifi signal. So if you find the 2.4G signal is unstable, please try to use WIFI 5G AP. (Please refer to: www.raspberrypiwiki.com/index.php/X825#Document)
We think this is caused by the unreliability of the Raspberry Pi's wifi design. If the Raspberry Pi Foundation reserves the SMA IPEX antenna interface, everything will become easier. We will also struggle to solve this issue in the future.
