Dell JW552 300 GB SAS Drive

The Dell JW552 is a new 300 GB internal hard drive built for server workloads. It spins at 15000 RPM with a 16 MB buffer and connects via a SAS 3Gb/s interface in a 3.5 inch form factor. It is validated for Dell PowerEdge and PowerVault systems.

Suits servers needing fast SAS storage.

This drive fits administrators replacing a failed drive in compatible Dell PowerEdge 1900, 1950, 2900, 2950, 6900 or 6950 servers and PowerVault MD1000 or MD3000 arrays. Systems without a SAS backplane or controller cannot use this unit. Buyers needing larger capacities or different physical formats should consider other options.

SAS 3Gb/s interface determines compatibility

The single specification that decides fitment is the SAS 3Gb/s interface. The host system must provide a matching SAS port and backplane to support the 15000 RPM spindle speed and 300 GB capacity. Verify the server or storage array model against the supported list before purchase.

Perguntas sobre este artigo

Will the 16 MB buffer need replacement or servicing over time?

The 16 MB buffer is integrated into the drive electronics and has no user-serviceable parts; it lasts for the life of the unit.

Does the 15000 RPM spindle or the SAS 3Gb/s interface hit its limit first during sustained workloads?

The 15000 RPM spindle determines sustained throughput, while the SAS 3Gb/s link caps burst transfers at 300 MB/s.

How much heat and noise does the 15000 RPM mechanism produce when running continuously in a server?

The drive is built for server environments such as PowerEdge 1900, 1950, 2900, 2950, 6900, 6950 and PowerVault MD1000, MD3000, where chassis airflow manages heat and acoustic output.
