Brand:

StarTech.com

StarTech.com SATSASBP425 is a four-bay mobile rack backplane that installs up to four 2.5-inch SATA or SAS HDDs/SSDs into a single 5.25-inch drive bay. Designed for servers, workstations and storage builds, it combines hot-swap drive access, lockable removable trays, dual 40mm cooling fans and a durable aluminum housing. Support for SATA III and SAS II enables transfer rates up to 6 Gbps with a compatible controller, while interchangeable trays simplify recurring drive replacement and backup workflows.

OVERVIEW

StarTech.com SATSASBP425 converts one available 5.25-inch bay into four removable 2.5-inch SATA/SAS drive bays, giving IT teams higher storage density and faster drive servicing. Compatibility: requires a 5.25-inch bay, four SATA/SAS host ports and suitable power connections. Compared with SATSASBP125: this model accommodates four drives instead of one. Requirement: compatible controller, drives and chassis airflow.

USE CASES

Add four 2.5-inch drives to a server with limited drive bays
Build compact SATA/SAS storage arrays
Expand workstation storage capacity
Create RAID storage with a compatible controller
Replace drives without opening the computer chassis
Support frequent drive exchange and maintenance
Build rotating backup-drive workflows
Consolidate multiple 2.5-inch drives into one 5.25-inch bay
Upgrade systems requiring removable SATA/SAS storage
Image multiple 2.5-inch drives in system-building environments

KEY FEATURES

Four 2.5-inch SATA/SAS bays - Adds four removable drives within a single 5.25-inch bay, increasing storage density without consuming multiple front-panel bays.
SATA III and SAS II support - Supports transfer rates up to 6 Gbps when paired with compatible drives and controllers, providing a practical interface for high-speed storage deployments.
Hot-swap capability - Allows compatible drives to be replaced or exchanged without shutting down the host system, reducing maintenance interruption.
5–15 mm drive-height support - Accommodates a broad range of 2.5-inch HDDs and SSDs, improving component-selection flexibility.
Lockable removable trays - Helps prevent unintended drive removal while providing convenient access for authorized maintenance.
50,000+ insertion rating - The NSS connectors are designed for frequent drive insertion and removal, supporting long-term operational use.
Two 40mm cooling fans - Improves airflow around installed drives to help manage operating temperatures in dense storage configurations.
Aluminum housing - Provides a durable enclosure with enhanced heat dissipation for installed storage devices.
Vertical or horizontal mounting - Provides installation flexibility where chassis layout or drive orientation varies.
Individual drive LEDs - Provides power and activity visibility for each installed drive, simplifying status checks during maintenance.
Interchangeable drive trays - Trays can also be used with the StarTech.com SATSASBP125 single-bay backplane, supporting a more flexible spare-drive strategy.
