Dell 300 GB 15K SAS Drive

This Dell 2.5 inch SAS hard drive delivers 300 GB of storage at 15000 RPM with a 16 MB cache. It is built for servers and workstations that need fast, reliable access to critical data. The drive suits database, virtualization and transactional workloads where consistent throughput matters more than raw capacity. Buyers who want more storage per bay should look at larger-capacity SAS models.

SAS 6 Gb/s Interface Limits

The SAS 6 Gb/s link caps sustained transfer rates well below the drive's mechanical potential. Real-world throughput is bound by the interface rather than the 15000 RPM spindle, so sequential reads and writes plateau at the bus ceiling. Latency-sensitive applications still benefit from the high rotational speed, but bulk data moves will not exceed the interface bandwidth. Systems limited to SATA 3 Gb/s ports will see further reductions.

15000 RPM Spindle Speed

The 15000 RPM rotation is the single specification that decides whether this drive fits the workload. It provides the low average latency and high IOPS needed for random, read-heavy tasks such as OLTP databases and virtual desktop infrastructure. Workloads that are purely sequential or capacity-oriented gain little from the faster spindle and may prefer a larger, slower drive. Match the spindle speed to the application profile before purchasing.

Perguntas sobre este artigo

Is the 300GB capacity the right choice for my workload?

The 300GB capacity suits operating systems, databases or applications that need fast access on a single 2.5" drive.

What does 15000RPM deliver inside a real server?

15000RPM reduces latency and raises sustained throughput for random I/O workloads compared with slower spindle speeds.

How does the SAS interface affect performance limits?

SAS supports dual-port operation and 6Gb/s signalling, letting the drive sustain its 15000RPM transfer rates without the bottlenecks of single-port SATA.
