Capacity and interface

The DELL 4H48X is a 1.8TB internal hard drive with a SAS 6Gb/s interface and a 2.5 inch form factor. It spins at 10000 RPM to serve workloads that demand consistent throughput. The drive suits servers and storage arrays that require a balance of capacity and response time. It is not intended for systems that only accept SATA signalling.

Sustained workload behaviour

At 10000 RPM the drive maintains steady data rates during extended read and write sequences rather than only in short bursts. The SAS interface supports dual-port operation for path redundancy in multi-controller environments. Performance scales with queue depth in transactional database or virtualisation workloads. It does not address latency-sensitive caching tiers that need solid-state speeds.

Build and mounting implications

The 2.5 inch form factor fits standard hot-swap bays and backplanes designed for enterprise chassis. SAS connectors combine data and power in a single plug for simplified cabling. Retail or OEM packing may vary, so mounting hardware is not guaranteed. Builders needing 3.5 inch bays or pure SATA backplanes must use an adapter or choose a different drive.

Questions about this item

How much power does the 10,000 RPM SAS drive draw during sustained operation?

The drive is built for a SAS 6Gb/s interface and spins at 10,000 RPM, which is typical for enterprise workloads where power draw is managed by the host controller and backplane.

What host connector and cabling does the 2.5" SAS drive require to function?

It needs a SAS 6Gb/s host port and a compatible SAS data and power cable; the 2.5" form factor fits standard drive bays or hot-swap trays that accept SAS drives.

Will the 1.8TB 10K SAS drive work in a system that currently uses 3.5" SATA drives?

The drive uses a SAS 6Gb/s interface, which is backward compatible with SATA 6Gb/s controllers, but the 2.5" form factor requires a 2.5" bay or a 3.5" adapter bracket to install alongside 3.5" drives.
