Dell 400-ALQC 4TB SAS hard drive
This 3.5-inch internal hard drive provides 4TB of storage on a SAS interface spinning at 7200 RPM. It is built for nearline workloads in Dell servers and storage arrays where hot-swap capability is required. The bare-drive packaging suits system integrators and IT departments replacing or expanding existing drive bays.
Upgrade from slower nearline SAS drives
The 12Gb/s transfer rate doubles the throughput of 6Gb/s nearline drives, cutting backup windows and speeding sequential reads for archival workloads. The jump is worth it when the controller and backplane both support 12Gb/s; on a 6Gb/s backplane the drive will negotiate down and the extra headroom goes unused.
Limits of 12Gb/s SAS interface
The interface tops out at 12Gb/s, so sustained throughput cannot exceed the electrical signalling limit regardless of spindle speed. Cable length, backplane design and controller firmware all introduce real-world overhead that reduces effective bandwidth below the nominal rate. Buyers needing higher random IOPS or lower latency should evaluate solid-state alternatives.

Otázky k tomuto produktu
Will the 3.5" form factor fit my standard drive bay?
The 3.5" form factor matches standard internal drive bays; ensure your chassis accepts 3.5" SAS drives.
How do I install the hot-swap tray correctly?
Slide the drive into the hot-swap tray until the SAS connector seats firmly; the common mistake is stopping before the latch clicks.
When should I plan to replace the 4TB SAS drive?
Replace the drive if SMART reports reallocated sectors or if sustained throughput drops below expected 7200 RPM levels.
