BestParts 575-BBSO HDD SSD Upgrade Kit for Precision T7920 - Adds 4

In this review of the BestParts 575-BBSO upgrade kit, the bottom line is clear: this kit is for technicians and power users who need extra internal storage in the rear FlexBays of a Precision T7920 or T7920XL. The reviewer found the kit delivers exactly what it promises, allowing installation of four additional 2.5in or 3.5in SATA or SAS drives and providing the necessary cabling for a MegaRAID controller. If you need more hotswappable capacity attached to a MegaRAID 9440-8i or 9460-16i, this kit solves that problem without modifying the main drive cage.

Key Features

• Compatibility: Designed specifically for Precision T7920 and T7920XL systems, ensuring a straightforward fit into FlexBay 3 and 4.
• Drive support: Adds space for four additional 2.5in or 3.5in SATA or SAS HDDs or SSDs to expand storage capacity.
• MegaRAID ready: Includes the cabling required to attach the added drives to MegaRAID controllers such as the 9440-8i or 9460-16i for hardware RAID setups.
• Complete kit contents: Ships with two cages, four caddies, two backplanes with cable, a bracket, an additional cable and screws so installers have the parts needed on hand.
• No chassis modification: Installs into the rear FlexBays without cutting or altering the main chassis, preserving system integrity.

Who It's For

This kit is aimed at system builders, IT technicians and workstation owners running Precision T7920 or T7920XL machines who need extra internal storage in the rear FlexBays and want direct connectivity to a MegaRAID storage card. It is especially useful when expanding a workstation used for video editing, large datasets or virtualization where local predictable RAID storage is preferred.

Users with other workstation models or those who require NVMe backplane support should look elsewhere, since this kit is tailored to the T7920 family and to SATA/SAS drives only. Casual users who rarely open their chassis may find the installation unnecessary and should consider external storage alternatives.

Pros & Cons

Pros

• Adds four additional internal drive bays for 2.5in or 3.5in SATA/SAS drives, increasing storage density.
• Includes cabling and backplanes to connect directly to MegaRAID controllers, simplifying RAID integration.
• Complete hardware set means fewer trips to the parts drawer during installation.

Cons

• Limited to Precision T7920 and T7920XL models, so it is not a universal solution for other chassis.
• No NVMe support is provided, so users needing PCIe SSD expansion will need a different kit.
