300GB 15000RPM SAS drive

The Dell ST3300555SS is a 300GB 3.5-inch internal hard drive spinning at 15000RPM with a SAS 3Gb/s interface and a 16MB cache. It is built for servers and workstations that need fast sequential access in a 3.5-inch form factor. The drive arrives new as a bare unit without brackets or cables.

Sustained throughput on SAS 3Gb/s

Under continuous load the 15000RPM spindle keeps sequential transfer rates steady across the 300GB capacity. The 16MB buffer absorbs burst requests while the SAS 3Gb/s link maintains consistent bandwidth during long write or read sessions. Performance scales with queue depth on compatible controllers.

Thermals and power in normal use

The 3.5-inch mechanism runs at typical enterprise temperatures when mounted with adequate airflow in a server chassis. Acoustic output is noticeable but expected for a 15000RPM spindle in rack environments. Power draw follows standard SAS 3Gb/s specifications for drives of this capacity and speed class.

Questions about this item

How much heat and noise should I expect from a 15000RPM SAS drive running continuously?

A 15000RPM spindle generates more heat and acoustic output than slower drives; ensure your chassis has adequate airflow over the 3.5" bays and plan for a higher thermal load during all-day operation.

What host interface and connector does the ST3300555SS require to function?

The drive uses a 3.5" SAS 3Gb/s interface, so the system must provide a compatible SAS backplane or controller with the correct power and data connectors for a bare 3.5" unit.

Can the ST3300555SS share a SAS controller with older 3Gb/s or slower SAS drives?

Yes, the 3Gb/s SAS link will negotiate down to match slower SAS devices on the same controller, allowing mixed-generation arrays to operate at each drive's rated speed.
