Dell 400-ASGQ 300GB 15K SAS Drive

This Dell 400-ASGQ is a 300GB 2.5" internal hard drive with a 12Gb/s SAS interface spinning at 15000 RPM. It uses SLC NAND flash memory and a 512n disk format. The bare drive is designed for hot-swap server bays.

Suits Dell PowerEdge R640 servers needing fast

This drive fits Dell EMC PowerEdge R640 servers that support 2.5" hot-swap SAS bays. It is not for systems lacking a 12Gb/s SAS controller or a compatible 2.5" hot-swap backplane. Buyers needing larger capacity or a different physical interface should look elsewhere.

12Gb/s SAS interface and 15000 RPM spindle speed

The single specification that decides compatibility is the 12Gb/s SAS interface combined with a 15000 RPM spindle speed. The host must provide a SAS 12Gb/s connection and a 2.5" hot-swap bay. Without that controller and bay, the drive cannot be installed or used.

Questions about this item

What does the SAS 12Gb/s interface cap the drive at in practice?

The SAS 12Gb/s interface limits the drive to a 12Gb/s transfer rate, which the 15000 RPM spindle and 512n format support for enterprise workloads.

What physical space and mounting does the 2.5-inch form factor need?

The 2.5-inch form factor fits standard 2.5-inch drive bays and supports hot-swap trays in compatible Dell EMC PowerEdge R640 servers.

How is the drive installed and what step is often missed?

Insert the bare drive into a hot-swap carrier, seat it in the server bay until it clicks, and ensure the SAS backplane is cabled for 12Gb/s operation.
