The Xpanstor 4-Bay NAS Storage Capacity Expander from ASUSTOR may be used to expand the capacity of your NAS and grow your workflow, or use it as a DAS (Direct-attached Storage) solution on your PC. It features four 3.5/2.5" SATA III drive bays and connects to your host system or NAS using its 10 Gb/s USB-C 3.2 Gen 2 port, while remaining backward compatible with 5 Gb/s USB 3.2 Gen 1. An internal 120mm fan helps keep things running cool and automatically adjusts itself according to hard drive temperatures, while support for RAID 0, 1, 5, 6, and 10 offers performance, data redundancy, or a combination of both. For those who do not require a RAID, JBOD and Single allow each drive to be utilized individually.
