Dell 401-AASN 1.8TB SAS Drive

This Dell 401-AASN is a 1.8TB 2.5 inch SAS hard drive spinning at 10000 RPM with a 12Gb/s transfer rate. It is supplied as a bare drive in original Dell packaging. The unit is built for internal desktop installations that require this specific Dell part number.

Suits SAS bays needing 10K speed

This drive fits systems that accept a 2.5 inch SAS interface and can use a 10000 RPM spindle. Buyers who require a different physical form factor or a slower rotational speed should consider other options. The bare drive packaging means no mounting tray is included.

12Gb/s SAS transfer rate

The interface runs at 12Gb/s, so the host controller or backplane must support that signalling speed. If the system only negotiates at a lower SAS rate the drive will still function but at the reduced speed. Verify the controller specification before purchase.

Questions about this item

Does the 401-AASN ship with a mounting tray or caddy for a 2.5" bay?

The drive is supplied as a bare unit without a tray; a compatible 2.5" SAS tray or caddy must be sourced separately for installation.

Should I choose the 1.8TB 10000 RPM model or a lower-capacity 10K SAS drive for my array?

Select the 1.8TB version when you need maximum raw capacity per spindle at 10K speed; pick a smaller 10K drive only if the array layout demands identical capacity across all slots.

Will the 12Gb/s SAS interface actually run at 12Gb/s in my server backplane?

The drive negotiates the highest speed the backplane supports; on a 12Gb/s SAS backplane it will operate at 12Gb/s, while on a 6Gb/s backplane it will run at 6Gb/s.
