Seagate

Seagate ST300MP0006 300GB 15000RPM SAS 12GB/s 256MB internal hard drive

SKU CH-21SR-06SW2

300 GB enterprise drive spinning at 15,000 RPM with a SAS 12 GB/s interface and 256 MB cache for low-latency server workloads

  • 15000 rpm spindle speed cuts latency to 2.0 ms
  • SAS 12GB/s interface delivers 1200 MB/s external transfer rate
  • 256 MB cache sustains 300 to 210 MB/s throughput
  • 300 GB capacity fits enterprise workloads
  • 70 W idle power reduces operating costs

Seagate 300GB 15K SAS Enterprise Drive

The Seagate ST300MP0006 is a 300GB enterprise hard drive spinning at 15000RPM with a SAS 12GB/s interface and 256MB cache. It is built for servers and storage arrays that demand low latency and high sustained throughput in a 2.5-inch form factor.

Suits latency-sensitive workloads.

This drive suits applications such as transactional databases, high-performance computing nodes, and tier-0 storage where the 2.0ms average latency and 300 to 210 MB/s sustained transfer rate matter. It is not for buyers who need more terabytes per spindle, nor for systems that lack a 12GB/s SAS host bus adapter or backplane.

15000RPM spindle speed decides fit

The 15000RPM spindle speed is the single specification that decides whether this is the right part; it delivers the 2.0ms average latency and 1200 MB/s external transfer rate that define the drive's performance envelope. If the workload can use that speed profile, the drive matches; if the priority is lower power or higher capacity at lower RPM, a different class of drive is required.

Questions about this item

What replacement interval should I plan for a 15000RPM enterprise SAS drive under heavy workloads?

Enterprise 15K drives are built for continuous operation; monitor SMART attributes and replace when reallocated sectors or seek errors begin to rise.

Which limit appears first during sustained transfers — the 300 to 210 MB/s media rate or the 1200 MB/s SAS interface?

The media sustains 300 to 210 MB/s from outer to inner diameter, so the physical platter speed is the bottleneck long before the 12Gb/s interface saturates.

How much heat and noise does the drive produce when running all day at 6.90W operating power?

Typical operating power is 6.90W with a 5V/12V draw of 6.90A; expect modest warmth and audible seek noise characteristic of a 15000RPM spindle.
