Dell 0WHR0G 1.8TB SAS drive

This 1.8TB SAS hard drive spins at 10000 RPM and connects through a 12Gb/s interface. It uses a 2.5 inch form factor and is supplied as a bare drive with hot-swap capability. The unit suits servers and storage arrays that need high-capacity rotational storage.

Practical limits of the 12Gb/s SAS interface

The 12Gb/s SAS link sets the maximum theoretical throughput, but sustained transfer rates stay lower because of the 10000 RPM mechanical latency. The drive cannot exceed the bandwidth of the controller or backplane it is attached to. Performance also depends on queue depth and the workload mix of random versus sequential access.

Installation notes and common issues

The hot-swap tray lets you insert or remove the drive without powering down a compatible chassis. You must verify that the server or enclosure accepts 2.5 inch SAS drives and that the backplane supports 12Gb/s signalling. A mismatched caddy or an older 6Gb/s backplane will prevent the drive from being recognised or will limit its speed.

Questions about this item

Should I pick the 1.8TB SAS 10K drive or a different capacity for my Dell server?

This model is offered as a single 1.8TB capacity; choose it when you need that exact space and 10000 RPM performance.

What does the 12Gb/s SAS rating deliver in a live server?

The 12Gb/s SAS interface supports up to 12Gb/s transfer rates when the backplane and controller also run at 12Gb/s.

Will the SAS 12Gb/s connection limit speed if my chassis only has 6Gb/s backplanes?

Yes, the drive will negotiate down to 6Gb/s on a 6Gb/s backplane, capping throughput at that lower rate.
