Manufacturer description
The Geekworm X825 V2.0 is a SATA expansion board that turns your Raspberry Pi 4 Model B into a compact storage server. It mounts a single 2.5-inch SATA hard drive or SSD directly beneath the Pi and supports UASP for faster USB-attached storage transfers. Geekworm rates it for HDDs up to 4TB. SSD capacity is not limited in principle, but drive thickness is limited by the standoff height and by whatever case you use. If you want a home NAS, the X825 V2.0 works with RaspNAS or OpenMediaVault, so you can share files, run backups or host media from a low-power Pi build. V2.0 replaces the X825…
