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.

Pitanja o ovom artiklu

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.
