Dell W345K 73 GB 15K SAS Drive

This Dell W345K is a 73 GB 2.5-inch internal hard drive spinning at 15K RPM with a SAS interface. It uses the Savvio 15K.2 platform and a 512n sector format. The unit is supplied new with updated firmware and tested components. It fits servers or workstations that accept 2.5-inch SAS drives.

Suits environments needing high spindle speed

Buyers who need more capacity per drive should look elsewhere. Systems that cannot accept a SAS connection will not be compatible. Workloads that prioritise sequential throughput over random IOPS may prefer a different storage type.

Questions about this item

Which capacity and speed variant of the Dell W345K SAS drive should I select?

The Dell W345K is offered as a single 73 GB model spinning at 15 K RPM with a 512 n sector format, so there are no alternative capacities or speeds to choose from.

What does the 15 K RPM rating mean for real-world performance in a server?

A 15 K RPM spindle delivers very low latency and high sustained throughput on the SAS interface, making the drive well suited for transaction-heavy workloads such as databases or email stores.
