  • 15 000 RPM for fast read and write performance

Lot of 10 enterprise SAS drives

This listing supplies ten new Dell XX518 hard drives, each a 146 GB 3.5-inch unit spinning at 15000 RPM. They are built for desktop workstations or servers that require a 3 Gb/s SAS connection and high rotational speed for transactional workloads. The drives arrive in original condition with manufacturer cache and interface specifications intact.

R Series caddy included

Every drive ships with an R Series caddy or tray, so the units can be slid directly into compatible Dell drive bays without sourcing separate mounting hardware. This saves installation time and ensures the correct mechanical fit for hot-swap chassis that accept the R Series form factor. No additional brackets or adapters are required for supported systems.

15000 RPM rotational speed

The 15000 RPM spindle speed is the defining attribute that determines whether this drive suits the intended workload; it delivers the low latency needed for database logs, email queues or other random I/O patterns. Buyers who need larger capacity per spindle or lower power draw for bulk storage should look elsewhere.

Spurningar um þessa vöru

Will the 16 MB cache need replacement over time?

The 16 MB cache is built into the drive and does not require separate maintenance or replacement.

What limits sustained write performance at 15000 RPM?

The 3 Gb/s SAS interface caps the maximum data transfer rate at 3 GBps, which becomes the bottleneck during continuous operation.

How much power and heat does a 15000 RPM SAS drive produce all day?

Running at 15000 RPM with a 3 Gb/s SAS interface, the drive draws typical enterprise 3.5" power and generates noticeable heat, so adequate case airflow is recommended.
