Dell X150K SAS hard drive

This Dell X150K drive is a 300GB 3.5 inch SAS hard drive spinning at 15000 RPM with a 64MB buffer. It includes an R Series caddy for hot-swap installation in compatible Dell enterprise servers and storage arrays. The 6Gb/s interface supports high-throughput transactional workloads. Condition is new.

Suits transaction-heavy workloads

Database administrators and virtualization hosts needing low-latency random I/O will benefit from the 15000 RPM spindle speed. Buyers who want more storage capacity per drive should look at larger-capacity SAS or nearline models. Systems without a SAS backplane or HBA cannot use this drive. The 300GB limit also rules out capacity-focused cold storage tiers.

15000 RPM spindle speed

The 15000 RPM rotational speed is the single specification that determines whether this drive meets your latency budget. It delivers the fastest mechanical access time in the Dell X150K line for OLTP and high-IOPS applications. If your workload is sequential or capacity-bound, a slower nearline drive will be more cost-effective.

Questions about this item

Should I pick the 300GB 15K SAS drive or a larger capacity model?

Choose the 300GB 15000RPM SAS drive when you need the lowest latency for random I/O workloads such as transactional databases; select a higher-capacity model only if raw storage space matters more than response time.

What does 15000RPM actually deliver inside a server?

The 15000RPM spindle speed reduces rotational latency, giving faster random read and write performance for I/O-intensive applications like virtualisation and online transaction processing.

How does the SAS 6Gb/s interface limit real-world throughput?

The SAS 6Gb/s link caps maximum sequential transfer at the interface rate, so sustained throughput cannot exceed that ceiling even though the 64MB cache helps burst performance.
