Dell 400-ASSX 8TB SATA HDD

The Dell 400-ASSX is an 8TB desktop internal hard drive built for bulk storage in workstations and servers. Its 7200 RPM spindle and SATA 6.0Gb/s interface suit users who need large capacity for archives, backups or media libraries.

Check 3.5-inch bay and SATA port

Verify that your chassis has a free 3.5-inch drive bay and that the motherboard or controller provides an unused SATA 6.0Gb/s port. Ensure the power supply includes a spare SATA power connector for the drive.

Sustained throughput at 7.2K RPM

Under continuous workloads the 7200 RPM mechanism delivers steady sequential transfer rates up to the SATA 6.0Gb/s link limit. The drive maintains consistent performance during long backup or video ingest sessions without the thermal throttling seen in faster, smaller form factors.

Questions about this item

Does the Dell 400-ASSX 8TB drive ship with a mounting tray or cables, or do I need to buy them separately?

The drive is supplied in retail or OEM packaging that may vary; a mounting tray and SATA data or power cables are not included and must be sourced separately if your system requires them.

Should I choose the 8TB 7200 RPM version or a different capacity for a desktop that needs fast bulk storage?

The 8TB 7200 RPM model delivers the highest capacity and spindle speed in this Dell part series, making it the best fit for large-volume, performance-oriented desktop storage.

What does the 6.0Gb/s SATA rating mean for actual throughput once the drive is installed in my PC?

The 6.0Gb/s SATA link sets the interface ceiling; real-world sustained transfer rates are determined by the 7200 RPM platters and typical desktop workloads.
