Dell 401-AASM 1.2TB SAS drive
This Dell 401-AASM is a 1.2TB 2.5 inch SAS hard drive spinning at 10000 RPM. It is built for servers and storage arrays that need hot-swap capability and consistent throughput. The bare-drive packaging suits integrators replacing or expanding existing Dell configurations.
Capacity and throughput
The 1.2TB capacity provides substantial space for databases, virtual machines or archival workloads. At 10K RPM the drive delivers low average latency for random read and write patterns. Sequential transfers peak at the SAS 12Gb/s interface rate, though sustained throughput will fall below that ceiling.
SAS 12Gb/s interface limits
The SAS 12Gb/s link sets the maximum burst transfer rate for this drive. Real-world sustained speeds are constrained by the 10K spindle speed and mechanical seek time. The interface is backward compatible with 6Gb/s SAS controllers, but the drive will then operate at the lower link speed.

- 10,000 RPM spindle delivers fast data access
- SAS interface supports 12Gb/s transfer rate
- 5-inch form factor fits dense server bays
- Hot-swap tray enables drive replacement without downtime

Questions about this item
Will the 401-AASM 1.2TB SAS drive work in a server backplane that only supports 6Gb/s SAS?
The drive negotiates down to 6Gb/s SAS, so it will operate on a 6Gb/s backplane at the lower speed while keeping its 10000 RPM spindle and 1.2TB capacity.
How can I verify the 401-AASM is running at its rated 12Gb/s transfer rate after installation?
Check the link speed reported by the RAID controller BIOS or OS utility; it should show a 12Gb/s SAS link and the drive should identify as a 1.2TB 10000 RPM SAS device.
Does the 401-AASM ship with a hot-swap tray or caddy, or must I buy one separately?
The drive is supplied as a bare 2.5" unit with a hot-swap tray type designated; a compatible Dell tray or caddy must be sourced separately if your chassis does not already include one.
