Dell 400-ALOB 2 TB nearline SAS drive

This 2 TB nearline SAS drive is built for Dell PowerEdge servers that accept 3.5 inch hot-swap bays. It suits administrators who need bulk capacity for archival, backup or secondary workloads in a 12 Gb/s SAS environment.

Capacity and headroom

The 2 TB platters spinning at 7200 RPM provide ample space for large datasets and sequential workloads. Random I/O intensive applications such as heavy databases will reach the mechanical limits of a single spindle before the interface saturates.

SAS 12 Gb/s interface limits

The SAS 12 Gb/s link delivers high throughput for streaming reads and writes, yet the 7200 RPM mechanics cap sustained transfer rates well below the bus maximum. Workloads demanding consistent low latency or higher IOPS will need faster media or multiple drives in an array.

Questions about this item

Will the 400-ALOB SAS 12Gb/s drive work in my existing PowerEdge R730 (3.5") backplane?

Yes, the 400-ALOB is designed for PowerEdge R730 (3.5") and other 13G servers with SAS backplanes.

How can I verify the 7.2K RPM NLSAS drive is operating correctly after installation?

The drive will be recognised by the RAID controller BIOS and iDRAC, showing 2TB capacity, SAS 12Gb/s link speed and healthy SMART status.

Does the 400-ALOB come with the Gen-13 R7FKF Dell tray or must I buy it separately?

The supplier title lists the Gen-13 R7FKF Dell tray, so the hot-plug carrier is included; no separate tray purchase is required.
