300 GB 15K RPM SAS Enterprise Drive

This 2.5 inch enterprise hard drive delivers 300 GB of storage on a 12 Gb/s SAS interface with a 15000 RPM spindle speed and a 128 MB buffer. It is built for servers and storage arrays that require fast transaction processing and consistent low latency. The 512 native sector format ensures broad compatibility with existing enterprise controllers and operating systems.

Upgrade From 3.5 Inch Mission Critical Drives

The drive replaces legacy 3.5 inch mission critical drives by doubling storage capacity in the same footprint while cutting power consumption. The jump is worth it when rack density and faster time-to-revenue are priorities over raw capacity per spindle. Buyers who need larger single volumes or lower cost per gigabyte should look elsewhere.

Practical Limits Of 12 Gb/s SAS

The 12 Gb/s SAS interface provides high throughput for enterprise workloads but remains bound by the mechanical latency of a 15K RPM spindle. Random I/O performance scales with queue depth yet cannot match solid state media for latency sensitive tasks. The 0.44 % AFR rating reflects enterprise grade endurance within the mechanical design envelope.

Questions about this item

Will the 2.5-inch form factor fit my server drive bay?

The drive uses a standard 2.5-inch form factor designed for enterprise server bays and compatible laptop chassis.

How do I connect the SAS 12Gb/s interface correctly?

Attach the drive to a 12Gb/s SAS backplane or HBA using a SAS cable; the port is keyed to prevent upside-down insertion which is the common error.

When should I plan to replace this 15K RPM enterprise drive?

The drive carries a 0.44% annualised failure rate rating; monitor SMART attributes and replace if reallocated sectors or humidity warnings appear.
