DELL PX05SRB04BY SDFAM83DAB01 480GB SAS 2.5 12Gb/s internal hard drive

SKU CH-A2P5-RYQAD MPN PX05SRB04BY

A 480GB SAS solid-state drive built for read-intensive workloads in compatible Dell servers

  • 480 GB capacity supports read-intensive workloads
  • SAS 12 Gb/s interface enables fast data throughput
  • 5 inch form factor fits compatible Dell servers
  • MLC flash technology provides reliable read performance
  • New condition ensures full manufacturer specification compliance

Purpose and fit

This 480GB SAS solid-state drive is built for read-intensive workloads in compatible Dell PowerEdge and PowerVault servers. It suits administrators who need fast, consistent access to data sets that are written once and read many times. Buyers who need heavy write endurance or larger capacities should look elsewhere.

Interface limits

The SAS 12Gb/s interface sets the maximum transfer rate, so throughput cannot exceed that link speed even if the flash memory is faster. The drive plugs into a 2.5-inch bay and relies on the host controller for command queuing and error handling. Systems without a 12Gb/s SAS backplane will run at the lower negotiated speed.

Build and connectors

The drive uses a standard 2.5-inch SAS connector that mates directly with hot-plug trays in the listed Gen13 Dell servers. No adapter brackets or cable assemblies are required for installation in those chassis. The MLC flash and read-intensive firmware tuning favour steady read performance over sustained write cycles.

Questions about this item

Should I pick the 480GB SAS 12Gb/s version or a different capacity for my server?

The 480GB capacity is the only size listed for this PX05SRB04BY model; choose it when your workload fits within that space and you need the 12Gb/s SAS link.

What does the 12Gb/s SAS rating actually deliver inside a Dell PowerEdge R720?

The 12Gb/s SAS interface provides up to 12 gigabits per second of bus bandwidth; real-world throughput depends on the controller, queue depth and the read-intensive MLC NAND in this drive.

Which SAS standard does this 2.5-inch SSD use and what speed ceiling does it impose?

It uses a 12Gb/s SAS connection, capping the host link at 12 gigabits per second; the drive will negotiate down to 6Gb/s or 3Gb/s if the backplane or controller requires it.
