Description
The SilverStone FS304-V (SST-FS304B-V) is a robust storage backplane designed for professionals and enthusiasts who need to maximize their system's storage density without sacrificing accessibility. By utilizing three standard 5.25-inch external drive bays, this mobile rack provides four hot-swappable 3.5-inch drive slots compatible with both SAS 12Gbps and SATA 6Gbps interfaces. A standout feature is the inclusion of a 9.5mm slim optical drive (ODD) slot, allowing users to maintain legacy media support while significantly expanding their hard drive capacity.
This product is for:
- Home Lab Enthusiasts: Ideal for building high-capacity DIY NAS units or media servers within standard ATX tower cases.
- Video Editors and Content Creators: Provides a reliable method for swapping high-capacity 3.5-inch HDDs for project archiving and rapid data offloading.
- IT Professionals and System Integrators: Perfect for server environments requiring hot-swap capabilities for zero-downtime drive maintenance and replacements.
- Legacy Hardware Users: Supports those who still require a slim optical drive for software installation or media playback alongside modern high-speed storage.
- Data Center Operators: The SAS 12G compatibility ensures high-throughput performance for enterprise-level storage arrays and RAID configurations.

Installing the FS304-V is a seamless process for any chassis with three available 5.25-inch bays. The trayless design facilitates quick drive insertion and removal, while the individual status LEDs provide immediate visual confirmation of drive health and activity. During heavy workloads, the integrated 92mm fan maintains consistent airflow across the drives, effectively preventing thermal throttling. The industrial-grade steel construction minimizes vibrations, ensuring the longevity of mechanical hard drives during high-speed operations.
Compared to standard internal drive cages, the SilverStone FS304-V offers the distinct advantage of front-access hot-swapping, removing the need to open the chassis for drive maintenance. While many 3-to-4 bay adapters occupy the entire space, the FS304-V intelligently retains a 9.5mm slim ODD bay, making it more versatile than the SilverStone FS303 or generic mobile racks. Its support for SAS 12G also places it ahead of consumer-grade SATA-only enclosures, meeting the demands of enterprise-level throughput.
Q&A:
- Does the FS304-V support 2.5-inch SSDs? While natively designed for 3.5-inch drives, 2.5-inch drives can be used if paired with a standard 3.5-inch adapter bracket.
- What power cables are required for this unit? The unit features both a SATA 15-pin and a Molex 4-pin connector to ensure stable power delivery to all four drives and the cooling fan.
- Can I use SAS drives with a standard SATA motherboard? No, while the FS304-V backplane supports SAS, your motherboard or RAID card must have a SAS controller to recognize SAS drives.
- Is the cooling fan replaceable? Yes, the 92mm fan is a standard size, allowing users to swap it for a different model if they prefer specific acoustic or airflow profiles.
- Does this support hot-plugging? Yes, the backplane is designed for hot-swap functionality, provided your operating system and AHCI/RAID settings are correctly configured.
