Why consider this model?

  • The FS3420 fits a business plan that needs 24 compatible 2.5-inch SATA SSD bays, a built-in 10GbE data path and DSM file/block services in a rack chassis.

Tradeoffs to weigh

  • The standard package is diskless, and SATA SSD compatibility, the separately sold RKS-02 rails, rack cooling, memory sizing and an independent backup all need planning. No shelf-bay expansion path is listed.
