1TB 7200 RPM SATA Enterprise Drive
This Dell 8DN1Y is a 1TB 2.5-inch internal hard drive spinning at 7200 RPM with a SATA 6.0Gb/s interface and 128MB buffer. It ships new with a hot-swap tray designed for 13G PowerEdge servers.
Suits 13G PowerEdge bays.
The included tray fits 13G PowerEdge hot-swap bays, so administrators replacing failed drives or adding capacity in those chassis can install it directly. Builders using standard desktop cages or laptops without hot-swap backplanes cannot mount the supplied tray and should look elsewhere.
512N sector format decides compatibility
The drive uses a native 512-byte sector size (512N), which determines whether the RAID controller, operating system or backup software will recognise and align the volume correctly. Verify that your controller and OS support 512N before purchase.

Questions about this item
Will the 7200 RPM spindle speed become a bottleneck during sustained sequential writes on the SATA 6.0Gb/s interface?
The drive spins at 7200 RPM and uses a SATA 6.0Gb/s link, so the mechanical throughput limit is reached before the interface saturates during long sequential transfers.
How much heat and noise does the 2.5" enterprise drive produce when running continuously in a 13G PowerEdge server?
In a 13G PowerEdge chassis the 2.5" drive operates within Dell's specified thermal envelope; fan speed ramps to keep temperatures in range and acoustic output stays at typical enterprise idle and seek levels.
Does the included hot-swap tray fit every 13G PowerEdge bay or do I need a specific backplane version?
The supplied tray is built for 13G PowerEdge 2.5" hot-swap bays; it matches the standard SFF sled used across that generation.
