Purpose-built storage
The Dell 400-ALRS is a 2TB 3.5 inch internal hard drive that uses a SAS 12Gb/s interface and spins at 7200 RPM. It is designed for servers and workstations that need consistent throughput on a nearline workload.
Build and connectivity
The drive ships as a bare 3.5 inch unit with hot-plug capability, so it can be inserted or removed from a compatible bay without powering down the chassis. Its SAS connector supports 12Gb/s signalling and the 512n sector format ensures broad controller compatibility.
Upgrade path
This drive replaces slower nearline SAS units or smaller-capacity 7.2K spindles when capacity and sustained transfer matter. The jump is worth it for arrays that need 2TB of hot-swappable storage on a 12Gb/s backplane.

Bu ürünle ilgili sorular
Does the SAS 12Gb/s interface cap real throughput below the 12Gb/s line rate?
The Nearline SAS 12Gb/s interface runs at the full 12Gb/s link speed; sustained transfer is limited by the 7200 RPM mechanicals, not the interface itself.
What physical space and mounting does the 3.5" hot-plug drive need?
It fits a standard 3.5" drive bay with a hot-plug carrier; the 512n sector format matches legacy and modern controllers alike.
How is the drive installed and what step do people miss?
Slide the bare drive into the server hot-plug tray, lock the lever, and insert the tray until the latch clicks — forgetting to fully seat the tray is the common error.
