Drive cage for three 5.25" bays

The SilverStone FS304B-V converts three standard 5.25-inch device bays into four hot-swap slots for 3.5-inch SAS 12Gbit/s or SATA 6Gbit/s drives. A built-in cooling fan and independent LED indicators help maintain temperatures and show drive status at a glance. The cage also accepts a 9.5 mm slim optical drive, adding legacy media support to modern server builds. It is aimed at administrators who need dense, serviceable storage in a familiar front-panel footprint.

Suited for SAS and SATA hot-swap arrays

This unit fits environments that rely on 3.5-inch hard drives with SAS 12G or SATA 6G interfaces and require tool-less drive replacement. The steel enclosure and plastic trays keep cost down while retaining the 12Gbit/s transfer capability of the series. Buyers needing support for 2.5-inch drives, additional optical bays beyond the single slim ODD slot, or a different bay-to-drive ratio should evaluate other models.

Single 12Gbit/s backplane interface

The cage delivers up to 12Gbit/s throughput per drive through its SAS/SATA backplane, which is the specification that determines whether the host controller and cabling can saturate the installed drives.
