An 8 TB nearline SAS hard drive spinning at 7200 RPM in a 3.5 inch form factor with a 12 Gb/s interface
The Dell 400-AHIZ is an 8TB 3.5-inch nearline hard drive built for Dell PowerEdge and PowerVault servers. It spins at 7200 RPM and connects through a SAS 12Gb/s interface for consistent throughput in multi-drive arrays. The drive ships as a bare unit with a tray included for direct installation into compatible bays. It targets administrators expanding bulk storage in supported Dell rack or tower platforms.
Confirm that your server chassis accepts 3.5-inch SAS drives and that the backplane supports 12Gb/s signalling before ordering. The included tray matches Dell drive bays; non-Dell enclosures may require a different carrier or adapter. Check the system’s drive-count limit and RAID controller firmware to ensure the 8TB capacity is recognised. Without a compatible SAS host bus adapter or integrated controller the drive will not function.
The supplied tray locks the drive into Dell hot-swap bays so it can be inserted or removed while the system runs. No cables, mounting screws or software utilities are bundled beyond the tray itself. Firmware updates and diagnostics must be obtained from Dell support using the 400-AHIZ part number. The tray does not add encryption, caching or any management feature beyond mechanical compatibility.

The drive ships as a bare unit in OEM packaging; the tray shown for PowerEdge and PowerVault servers is not included and must be sourced separately if your chassis requires it.
Choose the 8 TB 7.2K SAS drive when you need high-capacity bulk storage on a 12 Gb/s SAS backplane; smaller capacities suit tighter budgets while larger ones exceed the 8 TB limit of this part.
The 12 Gb/s interface sets the maximum link speed to the controller; sustained read and write rates are governed by the 7200 RPM platters and will be lower than the bus ceiling.
