Dell 300 GB SAS 12Gb/s 15K RPM Drive

The Dell 400-ATII is a 300 GB internal hard drive with a 2.5-inch form factor and a SAS 12Gb/s interface. It spins at 15000 RPM to provide fast disk access for transactional workloads. The 512n sector format suits legacy applications that expect traditional sector sizes. It targets administrators expanding storage in compatible Dell PowerEdge servers.

Hot-plug installation in supported bays

The drive is hot-pluggable, so it can be inserted or removed while the server is running when used in a supported hot-swap bay. Installation requires a compatible 2.5-inch SAS backplane and the correct drive carrier for the specific chassis. Problems usually arise when the backplane firmware is outdated or when a non-Dell carrier prevents the drive from seating properly.

300 GB for high-speed transactional data

The 300 GB capacity handles operating system volumes, database logs and high-performance scratch space where low latency matters more than bulk capacity. The 15000 RPM spindle speed keeps random I/O responsive under heavy queue depths. It runs out of space quickly for media archives, backups or large file repositories where capacity per drive is the priority.

Questions about this item

How can I confirm the drive is spinning at 15000 RPM after installation?

The drive should be detected by the RAID controller or BIOS at 300 GB capacity with a SAS 12Gb/s link speed; SMART data or the controller log will report the 15000 RPM spindle speed.

Does the 400-ATII ship with a drive caddy or mounting screws for a PowerEdge R740?

The drive is supplied as a bare 2.5" hot-plug unit; Dell PowerEdge servers use a separate drive carrier that must be purchased or reused from the original configuration.

Should I choose the 300 GB 15000 RPM SAS model or a larger capacity for a PowerEdge R640?

Select the 300 GB 15000 RPM SAS drive when the workload demands the highest IOPS per terabyte; choose a larger-capacity model only if raw capacity outweighs peak transaction performance.
