Dell 400-ASHI 1.2TB SAS drive

The Dell 400-ASHI is a 1.2TB 2.5" SAS hard drive spinning at 10000 RPM with a 12Gb/s interface. It is built for Dell PowerEdge R740xd servers and other systems that accept 2.5" SAS drives. The 512n sector format keeps it compatible with legacy arrays and modern controllers alike.

Hot-swap tray installation

The drive ships as a bare unit without a caddy, so it slides into a compatible hot-swap tray or backplane. Alignment is straightforward when the tray matches the server chassis, but forcing the connector on a mismatched sled can bend pins. Verify the tray part number for your specific PowerEdge model before seating the drive.

Sustained 10K SAS workloads

At 10000 RPM the drive maintains consistent throughput for random I/O workloads such as databases or virtualisation hosts. The SAS 12Gb/s link and SLC NAND flash memory type support steady write performance without the thermal throttling seen in burst-only devices. It is not suited for archival cold storage where capacity per pound matters more than IOPS.

Questions about this item

How do I verify the drive is running at 10000 RPM and 12Gb/s SAS after installation?

Check the server BIOS or RAID controller interface; it will report the spindle speed as 10000 RPM and the negotiated link speed as 12Gb/s SAS for the 400-ASHI.

The drive is listed as bare drive packaging — what exactly ships in the box and what must I source separately?

Only the 2.5 inch 1.2TB SAS hard drive itself is included; you will need a compatible 2.5 inch hot-swap carrier or caddy for your PowerEdge R740xd.

The specs show 1.2TB capacity and 512n format — how do I decide if this version suits my array versus other capacities?

Choose the 1.2TB 512n model when your RAID controller requires native 512-byte sectors and you need 10K performance in a 2.5 inch SAS bay.
