Dell 400-AOJN 8 TB 3.5" SATA Drive

The Dell 400-AOJN is an 8 TB internal hard drive built for server and desktop storage. It operates at 7200 RPM with a SATA 6.0Gb/s interface and a 512e disk format. The 3.5-inch form factor fits standard drive bays in compatible Dell EMC PowerEdge systems.

Suited for Dell EMC PowerEdge T340 storage expansion

This drive matches the specified compatibility for the Dell EMC PowerEdge T340 server. It serves administrators adding bulk capacity to that platform. Buyers using other server models or non-Dell chassis should verify fitment before purchase.

512e disk format with SATA 6.0Gb/s interface

The drive presents 512-byte logical sectors while using 4 KB physical sectors on the media. This 512e format ensures broad operating system and controller compatibility. The SATA 6.0Gb/s interface determines the maximum host transfer rate.

Questions about this item

What does the 7200 RPM spindle speed mean for actual throughput in a server?

The 7200 RPM spindle speed supports sustained sequential transfers up to the SATA 6.0 Gb/s interface limit, typical for bulk storage workloads in a PowerEdge T340.

How does the SATA/600 interface standard cap real-world performance?

The SATA/600 interface caps the drive at 6.0 Gb/s maximum transfer rate, so sustained reads and writes cannot exceed that bandwidth regardless of spindle speed.

Will the 3.5" form factor fit directly into a PowerEdge T340 drive bay?

Yes, the 3.5" form factor matches the standard drive bays in the Dell EMC PowerEdge T340, so it installs without adapters.
