Dell 400-APTK 300GB 15K SAS Drive

This Dell 400-APTK is a 300GB 2.5 inch SAS hard drive spinning at 15000 RPM with a 12Gb/s interface. It is built for hot-swap bays in Dell PowerEdge servers and compatible storage arrays. The 15K spindle speed targets workloads that demand low latency and high random IOPS. Supplied new in retail or OEM packaging.

Suits transaction-heavy server workloads

Database servers, virtualisation hosts and high-performance caching tiers benefit from the 15000 RPM rotational speed and 12Gb/s SAS bandwidth. The hot-swap tray allows drive replacement without downtime. Buyers who need larger capacity per drive or who prioritise sequential throughput over random access latency should consider other options. Systems without a 12Gb/s SAS backplane or hot-swap cage cannot use this drive as intended.

15000 RPM spindle speed decides fit

The 15K RPM rating is the single specification that determines whether this drive matches the workload. It delivers the low access times required for heavy random read and write patterns such as OLTP databases and write-intensive caches. If the application can tolerate higher latency in exchange for more capacity per spindle, a lower-RPM drive is the logical alternative.

Questions about this item

How do I install the 400-APTK 2.5" SAS drive in a hot-swap bay, and what step is often missed?

Slide the drive into the bay until the SAS connector seats firmly; the step often missed is pushing far enough for the latch to click, which secures both data and power contacts.

What maintenance or replacement will the 15000 RPM 300GB SAS drive need later?

Plan to replace the drive after its rated service life or if SMART reports reallocated sectors; no user-serviceable parts exist inside the sealed helium enclosure.

What limit appears first on the 12Gb/s SAS drive under sustained heavy writes?

The 15000 RPM spindle hits its thermal ceiling first, causing the firmware to throttle write throughput to protect the mechanism.
