Silver 2.5 inch SAS hard drive with circuit board visible

Seagate

Seagate ST300MM0008 300 GB 10K RPM 2.5" 12 Gb/s SAS internal hard drive

SKU CH-2A8N-D5XA4 MPN ST300MM0008

300 GB 10K RPM 2.5" SAS drive with 12 Gb/s interface for enterprise servers

  • 300 GB capacity stores critical datasets
  • 10K RPM spindle accelerates transaction-heavy workloads
  • 12 Gb/s SAS interface doubles host throughput
  • 5-inch form factor fits dense server bays
  • 8 Gb/s backward link ensures legacy controller compatibility

Enterprise 300 GB 12 Gb/s SAS drive

The Seagate ST300MM0008 is a 300 GB internal hard drive with a 12 Gb/s SAS interface and a 10K RPM spindle speed. It uses a 2.5 inch form factor and is supplied new without a drive tray. The unit carries Dell part number YJ2KH for system compatibility.

Suited for SAS arrays needing 10K speed

This drive fits servers and storage arrays that require a 12 Gb/s SAS connection and 10K RPM performance in a 2.5 inch bay. It is not for systems that lack a SAS controller or that need a larger capacity than 300 GB. Buyers without a compatible backplane should look elsewhere.

12 Gb/s SAS interface decides fit

The single specification that determines compatibility is the 12 Gb/s SAS interface. The host must provide a SAS port and a 2.5 inch drive bay to accept this drive. Without that interface the drive cannot be used.

Questions about this item

How do I install the ST300MM0008 into a 2.5-inch SAS bay without a drive tray?

Slide the 2.5-inch drive directly into the hot-swap bay until the 12 Gb/s SAS connector seats firmly; the missing tray means you must align the connector by hand instead of relying on tray guides.

What part of the ST300MM0008 will need replacement first under heavy workloads?

The 10K RPM spindle and actuator bearings are the mechanical components most likely to wear out before the 12 Gb/s SAS interface or the 300 GB media.

At what point does the 12 Gb/s SAS link stop scaling during sustained writes?

The 10K RPM rotational speed limits sustained throughput long before the 12 Gb/s SAS bus saturates, so sequential performance plateaus at the drive’s mechanical maximum.
