Dell 480GB SAS enterprise SSD

This Dell PX05SRB04BY is a 480GB SAS 2.5-inch solid-state drive built for read-intensive server workloads. It uses MLC flash and a 12Gb/s SAS interface to deliver consistent throughput in multi-user environments. The drive targets administrators who need reliable capacity for databases, virtualisation hosts or logging tiers. It is not suited for workloads that demand sustained heavy write endurance.

Compatibility check before ordering

Verify that your server backplane and RAID controller support 2.5-inch SAS drives at 12Gb/s. Confirm the chassis has an available 2.5-inch bay and that the drive carrier matches your system generation. Cross-reference the approved server list to ensure the firmware and thermal profile are validated for your platform. Do not assume fitment in systems that are not explicitly listed.

Build quality and daily implications

The 2.5-inch form factor slides into hot-swap carriers on supported Dell PowerEdge and C-series servers. A single SAS connector handles both power and data, so cabling stays simple during replacement. Enterprise-grade MLC construction tolerates continuous read-heavy duty cycles without performance degradation. The drive ships new and carries a one-year warranty from the manufacturer.

Questions about this item

Does the 2.5" SAS 12Gb/s drive come with a caddy or bracket, or must I order one separately?

The drive ships as the bare 2.5" SAS unit; Dell server caddies are sold separately and must match your specific chassis.

Should I choose this 480GB read-intensive model or a larger capacity for my Dell R740?

Choose the 480GB read-intensive drive for boot, logging or caching workloads; select a higher capacity write-intensive model for databases or heavy write workloads.

What does the 12Gb/s SAS interface deliver in a Dell PowerEdge R740?

The 12Gb/s SAS link provides full controller bandwidth for consistent read-intensive performance in supported PowerEdge servers.
