Dell 900 GB SAS Drive

The Dell WD9001BKHG is a 900 GB 2.5 inch SAS hard drive spinning at 10000 RPM. It is built for servers and workstations that need fast, reliable storage in a small form factor.

6 Gbps SAS Interface

The drive connects through a 6 Gbps SAS link, which is the single specification that determines controller and backplane compatibility. Buyers whose systems only support SATA cannot use this drive.

Enterprise Thermal Profile

The 10000 RPM spindle draws more power and generates more heat than slower nearline drives, so adequate chassis airflow is required. Acoustic output is higher than desktop drives, which is typical for this class of enterprise storage.

Questions about this item

How does the 10000 RPM speed affect performance in a live server?

The 10000 RPM spindle delivers lower latency and higher sustained throughput for random I/O workloads such as databases or virtualization.

What does the 6G SAS interface limit in practice?

The 6G SAS link caps maximum transfer rate at 6 Gb/s, so sequential reads and writes cannot exceed that bandwidth even if the drive mechanics are faster.

Will this 2.5 inch drive fit a standard 3.5 inch hot-swap bay?

The 2.5 inch form factor requires a 2.5 inch bay or an adapter bracket; it will not seat directly in a 3.5 inch carrier.
