Dell 146GB 2.5" SAS drive purpose

This Dell X143K is a 146GB 2.5 inch internal hard drive spinning at 10000 RPM with a SAS 6Gb/s interface. It ships new with a tray for direct installation in compatible PowerVault servers or storage arrays. The 16MB buffer supports consistent throughput for enterprise workloads.

Suitable workloads and limits

The 10000 RPM spindle and SAS interface suit transactional databases, virtualisation hosts and logging arrays that demand low latency and sustained write performance. Buyers needing larger single-drive capacities or solid-state silence should consider alternative media. The 2.5 inch form factor limits use to bays or enclosures designed for that size.

146GB capacity decides fit

At 146GB the drive fills a specific niche: replacing failed disks in existing RAID sets or expanding legacy arrays where larger drives would exceed controller addressing limits. Verify the target system accepts 146GB SAS disks before purchase.

Otázky k tomuto produktu

What does the 10000 RPM spindle speed mean for everyday server workloads?

The 10000 RPM rotation reduces average rotational latency, giving quicker random read and write response times for transaction-heavy applications.

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

The SAS 6Gb/s link caps the maximum burst transfer rate at 6 gigabits per second, so sustained sequential speeds cannot exceed that ceiling.

Will the 2.5 inch form factor fit directly into a standard 3.5 inch drive bay?

The 2.5 inch drive requires a 2.5 inch bay or an adapter bracket to mount securely in a 3.5 inch slot.
