Dell MBD2147RC 146GB SAS Drive
This new Dell MBD2147RC is a 146GB 2.5-inch internal hard drive spinning at 10000RPM with a 6Gb/s SAS interface and a 16MB cache. It ships with an R Series caddy for direct installation in compatible Dell servers and storage arrays. The compact form factor suits high-density enterprise chassis.
Who this suits and who should look elsewhere
The drive suits administrators maintaining or expanding existing Dell SAS infrastructure that requires a 10K RPM spindle and a 146GB capacity point. It is not for buyers who need larger capacities, faster interfaces, or solid-state performance. Systems without a SAS backplane or controller cannot use this drive.
The deciding specification
The 6Gb/s SAS interface is the single specification that determines compatibility; the host must provide a SAS connection and the correct drive bay for the included caddy. Without a SAS controller this drive will not function.
Highlights
- 146 GB capacity supports data-intensive workloads
- 10000 RPM spindle speed reduces access latency
- SAS 6 Gb/s interface enables fast data throughput
- 16 MB cache buffers bursts for smoother I/O
- Includes R-Series caddy for tool-free 2.5-inch bay installation

Questions about this item
Will the 6Gb/s SAS interface negotiate down to 3Gb/s on an older backplane?
Yes, the 6Gb/s SAS link auto-negotiates to 3Gb/s on legacy controllers, so the 146GB drive remains fully usable.
How can I confirm the 10000RPM spindle and 16MB cache are active after installation?
Check SMART data or the RAID BIOS — both will report 10000RPM rotation and 16MB buffer size for the MBD2147RC.
Does the package include the R-Series caddy or must I source a 2.5" SAS tray separately?
The R-Series caddy is included with the MBD2147RC, so no additional tray is required for a 2.5" SAS bay.
