Dell ST3146356SS 146 GB 15K SAS drive

This new Dell Cheetah 15K.6 internal hard drive delivers 146 GB of storage on a 3.5-inch SAS 3 Gb/s interface. It spins at 15 000 RPM and includes a 16 MB buffer to accelerate data access. The package ships with an R Series caddy for direct mounting in compatible bays.

Suits Dell PowerEdge servers and MD arrays listed

The drive fits PowerEdge 1900, 1950, 2900, 2950, R300, R900, R905, T100, 105, 300 and MD1000, MD3000, MD3000i systems. Buyers needing larger capacities or a different interface should consider other options. It is not intended for platforms that lack a SAS backplane or the correct caddy.

15 000 RPM rotational speed

The 15 000 RPM spindle speed is the key specification that determines whether this drive meets the performance profile for transaction-heavy workloads. Verify that the target server supports 3.5-inch SAS drives at this speed before purchasing.

Questions sur cet article

How does the 15000 RPM spindle speed affect sustained write performance?

The 15000 RPM spindle keeps average latency low, so sustained write throughput stays closer to the SAS 3Gb/s interface limit during long transfers.

What noise and heat levels should I expect from the 15000 RPM drive running continuously in a server?

A 15000 RPM SAS drive generates more acoustic noise and heat than slower drives; plan for active airflow in the 3.5-inch bay to keep temperatures in spec.

Which controller or backplane do I need to connect this 3.5-inch SAS drive?

You need a SAS host bus adapter or RAID controller with a 3Gb/s SAS port, plus a compatible 3.5-inch drive bay or the included R-series caddy.
