Dell K07H8 4TB Nearline SAS Drive

This Dell K07H8 is a 4TB 3.5-inch internal hard drive built for nearline storage workloads. It uses a SAS 12Gb/s interface and spins at 7200 RPM. The drive is supplied new in either retail or OEM packaging.

Suited for hot-swap SAS bays

The unit includes a hot-swap tray so it can be inserted or removed without powering down a compatible server or storage array. It is not suitable for systems that cannot accept a 3.5-inch SAS device or that lack a hot-swap backplane. Buyers needing a different capacity or interface should consider other models.

SAS 12Gb/s interface determines compatibility

The single specification that decides fitment is the SAS 12Gb/s interface; the host controller and backplane must support this connection. Without a matching SAS port the drive cannot communicate with the system.

Questions about this item

What SAS controller or backplane do I need to run this 12 Gb/s drive?

A 12 Gb/s SAS host bus adapter or RAID card with a compatible 3.5" hot-swap backplane is required for full speed.

Will this Nearline SAS drive work in a server that currently uses 6 Gb/s SAS drives?

Yes, the 12 Gb/s interface negotiates down to 6 Gb/s automatically, so it runs alongside older drives.

How can I confirm the drive is operating at 7200 RPM after installation?

Check the SMART data or controller BIOS; both report the spindle speed as 7200 RPM when the drive spins up.
