The Synology FX2421 is a 24-bay flash expansion unit designed for businesses requiring high-density storage capacity and performance. This unit integrates with specific Synology FS series NAS models, including the FS6400, FS3600, and FS3400, provided the NAS runs DSM version 6.2.3-25426-2 or later. It supports 2.5" SAS HDDs, SAS SSDs, and SATA SSDs, offering a maximum internal raw capacity of 92.16 TB when populated with 3.84 TB drives. All drive bays are hot-swappable, and RAID management is handled through Synology DSM. The FX2421 is intended for organizations looking to expand their existing Synology flash storage infrastructure, addressing needs for increased data volume within a rack-mounted environment. It includes redundant power supplies and features an easy-replacement system fan for operational continuity. For optimal performance, it is recommended to create storage volumes physically within the same unit rather than spanning across the NAS and expansion unit.
