300 GB 15K RPM SAS drive

This Dell enterprise hard drive provides 300 GB of storage on a 2.5 inch form factor spinning at 15000 RPM. It uses a 12 Gb/s SAS interface with a 256 MB cache and 512n sector formatting. The unit ships new with zero hours of operation and includes an R Series caddy for installation.

12 Gb/s SAS interface limits

The drive connects through a 12 Gb/s SAS link which requires a compatible controller or backplane to reach full throughput. Performance will fall back to the speed of the slowest component in the chain. Cable length and signal quality also affect sustained transfer rates in multi-drive enclosures.

Check controller and bay compatibility

Verify that your server or storage array accepts 2.5 inch SAS drives with the supplied R Series tray. Confirm the backplane or HBA supports 12 Gb/s SAS and 512n sector geometry. Ensure firmware and drive carriers match the system vendor specifications before ordering.

Questions about this item

Which capacity and speed combination matches the ST300MP0026 part number?

This drive is the 300GB model spinning at 15000RPM with a 256MB cache and 512n sector format

How does the 15000RPM speed affect performance in a live server?

The high rotational speed cuts average latency and boosts random IOPS for transaction-heavy workloads

What does the SAS 12Gb/s interface limit in practice?

The 12Gb/s SAS link sets the maximum host transfer rate; sustained throughput will also depend on the drive's internal media speed
