Three 5.25-inch bays to five 3.5-inch drives

The SilverStone FS305-E converts three standard 5.25-inch front bays into five hot-swap trays for 3.5-inch SAS or SATA drives. It is aimed at workstation and server builders who need quick drive changes without shutting down the system. Each tray includes a metal key lock for physical security.

SAS 12 Gbit/s and SATA 6 Gbit/s interface limits

The backplane supports SAS at 12 Gbit/s and SATA at 6 Gbit/s, so drive throughput is bounded by those link rates and the host controller you connect. The built-in cooling fan helps sustain performance during continuous operation, but the cage itself does not raise the interface ceiling beyond the stated standards.

Five-drive capacity with single-fan cooling

Five 3.5-inch drives fit in the space of three 5.25-inch bays, giving dense storage for RAID arrays or large media libraries. The single included fan provides baseline airflow; heavily loaded arrays or high-RPM drives may need additional case ventilation to keep temperatures in check.

Questions about this item

Should I pick the 3.5" drive version or the 5.25" bay version?

The cage fits three 5.25" front bays and holds five 3.5" drives, so you use the 5.25" bays to gain five 3.5" slots.

What does the 12G SAS rating actually deliver inside my PC?

Each bay supports SAS-12G and SATA 6Gbit/s, so a SAS drive can run at up to 12 Gbit/s while a SATA drive is limited to 6 Gbit/s.

Does the SAS-12G interface cap the speed of my SATA drives?

The backplane carries both SAS-12G and SATA 6Gbit/s; SATA drives operate at their native 6 Gbit/s and are not limited by the SAS-12G capability.
