Dell 1.2TB 10K SAS 12Gb/s Drive

The Dell 400-ATJL is a 1.2TB 10000 RPM internal hard drive with a SAS 12Gb/s interface in a 2.5 inch form factor. It is built for Gen 14 PowerEdge servers and includes a 128MB cache. The drive supports hot swap installation for compatible bays. It ships new from the manufacturer.

Suits High-IO Server Workloads

This drive suits administrators who need 10K rotational speed and a 12Gb/s SAS link for database or virtualisation workloads. Buyers who require larger capacity per bay should look at higher-density alternatives. Systems limited to 6Gb/s SAS or SATA backplanes will not utilise the full interface bandwidth. Laptop or desktop builders needing a SATA drive cannot use this SAS model.

SAS 12Gb/s Interface Decides Compatibility

The single specification that decides fit is the SAS 12Gb/s interface combined with the 2.5 inch hot swap form factor. Your server backplane and controller must support 12Gb/s SAS signalling to operate the drive at its rated speed. Verify the drive tray and caddy match the Dell Gen 14 PowerEdge form factor before ordering.

Questions about this item

Does the 400-ATJL drive ship with a mounting bracket or caddy for a Gen 14 PowerEdge bay, or must that be purchased separately?

The drive is sold as the bare 2.5" unit; Dell Gen 14 PowerEdge hot-swap bays require a separate Dell caddy or tray that matches your specific chassis.

How do I decide between the 1.2TB 10K SAS model and a larger-capacity 10K SAS drive for the same server?

Choose the 1.2TB model when you need the 10000 RPM speed and 128MB cache for transaction-heavy workloads but the dataset fits within 1.2TB; step up to a higher-capacity 10K SAS drive only if you need more raw space at the same performance tier.

What does the 12Gb/s SAS interface actually deliver inside a Gen 14 PowerEdge server?

The 12Gb/s SAS link provides up to 12 Gbit/s per lane to the RAID controller or backplane, letting the 10000 RPM platters and 128MB cache sustain high random IOPS for database and virtualization workloads.
