Server Storage Drive

The Seagate Cheetah 15K.6 ST3146356SS is a 3.5-inch internal hard drive built for server environments. It delivers 146GB of capacity with a 15000 RPM spindle speed and a SAS 3Gb/s interface. The 16MB cache supports the high throughput demanded by transactional workloads.

Fit and Limits

This drive suits administrators maintaining legacy SAS arrays that require a 15K RPM replacement part. It is not for buyers who need larger capacities than 146GB or who require a modern interface standard beyond SAS 3Gb/s. Systems without a compatible SAS controller cannot use this drive.

Deciding Specification

The SAS 3Gb/s interface is the single specification that determines compatibility. The drive will only function in backplanes and controllers that explicitly support this signalling rate. Verify the host bus adapter or RAID card lists SAS 3Gb/s before purchase.

Questions sur cet article

How much heat and noise does the 15000 RPM Cheetah 15K.6 generate when running continuously in a server?

The 15000 RPM spindle and 3.4 ms average seek time mean higher sustained heat and audible whine than slower drives; plan for active airflow in the chassis.

What controller or backplane must I already have for the SAS 3Gb/s interface on this ST3146356SS?

A SAS 3Gb/s HBA, RAID card or server backplane with a standard SAS data and power connector is required for the drive to function.

Will the 3.5-inch form factor and SAS interface let me keep using my older 3Gb/s SAS enclosure?

Yes, the 3.5-inch form factor and native SAS 3Gb/s interface match legacy SAS enclosures and backplanes directly.
