    X829 Dual 2.5" SATA HDD/SSD Shield Hardware   Software
    Product Description 
  The X829 dual 2.5" SATA HDD expansion board, offering an easy and fast way to create bigger storage solution for your Raspberry Pi 4B. Its elegant and ultra-compact design allows two 2.5" HDD/SSD to be conveniently attached to Raspberry Pi 4. The SuperSpeed USB 3.0 port delivers a blistering data transfer rate of up to 5Gbps, letting you transfer a large amount of data in seconds. The mounting holes and standoffs help protect the hard disk drives, while effectively drawing the heat away from the drive for reliable performance. The built-in LED light indicates the reading or writing status – no more guesswork again.

The X829 can be the perfect storage solution for your home media center and building Network-attached storage (NAS) for storing and streaming your own videos, music, and digital photos around the house and even across the world. the X829 also supports operating system booting from your HDD/SSD for faster app opens, web serving and file copying.
