DELL 400-ALRS 2 TB 7.2K 3.5" SAS 12Gbps 512n Hot-Plug Hard Drive

SKU CH-1DDC-Z7AHF

A 2 TB 7.2K 3.5" SAS 12Gbps 512n hot-plug hard drive for internal storage

  • 2 TB capacity stores large datasets
  • 7200 rpm spindle speed delivers responsive throughput
  • 12 Gb/s SAS interface supports high-bandwidth transfers
  • 512n sector format ensures broad system compatibility
  • Hot-plug 3.5" form factor enables drive swaps without downtime

Dell 400-ALRS 2 TB NL-SAS Hard Drive

This Dell 400-ALRS hard drive provides 2 TB of storage in a 3.5 inch form factor. It uses a Near Line SAS interface operating at 12 Gb/s with a 512n disk format. The drive spins at 7200 rpm and supports hot-plug installation for compatible internal bays. It is a new component designed for nearline storage applications.

Suited for servers and arrays needing hot-plug 12

This drive fits systems that accept 3.5 inch internal hot-plug SAS drives and require 512n sector formatting. Buyers whose chassis lacks a SAS backplane or controller, or who need solid-state performance, should look elsewhere. It is not suitable for laptops, desktops without SAS infrastructure, or external enclosures without the correct interface.

The deciding specification is the 12 Gb/s Near

Compatibility depends entirely on the host system providing a 12 Gb/s SAS connection and a 3.5 inch hot-plug bay. Without a matching SAS controller and backplane, the drive cannot function. Verify the server or storage array supports NL-SAS at this speed before purchase.

Questions about this item

Will the 7200 rpm spindle in this 400-ALRS drive require bearing service during its service life?

The drive uses a sealed 7200 rpm spindle assembly that is not user-serviceable; replacement of the entire unit is the standard approach if a bearing fails.

Does the 12Gb/s SAS interface or the 7200 rpm spindle become the throughput bottleneck first during sustained writes?

At 7200 rpm the mechanical media typically saturates well below the 12Gb/s SAS ceiling, so the spindle speed is the first limit under sustained write workloads.

How much heat does the 3.5" 2 TB NL-SAS drive add to a chassis running all day?

The 3.5" form factor dissipates heat through the hot-plug carrier; typical near-line SAS drives at this capacity run warm but within standard server cooling envelopes.
