  • 15000 RPM spindle speed delivers rapid read and write performance
  • SAS 3 Gb/s interface provides fast data transfer for desktop workloads

  • 16 MB cache accelerates access to frequently used records
  • Includes R Series caddy for direct fit in compatible PowerEdge servers

146 GB 15 000 RPM SAS drive for servers

This 146 GB internal hard drive uses a 3.5 inch SAS interface running at 3 Gb/s and spins at 15 000 RPM with a 16 MB buffer. It is built for Dell PowerEdge servers that require high-speed mechanical storage. The unit ships new with zero power-on hours and includes an R-series caddy for direct mounting.

Replaces slower 10 000 RPM SAS disks

The jump is worth it when your workload demands lower latency and higher sustained throughput than 10 000 RPM drives can deliver. Typical candidates are database logs, transactional workloads and virtualisation hosts running on the listed PowerEdge models. It will not help buyers who need more capacity per bay or who have moved to solid-state storage.

Simple caddy installation on supported PowerEdge

Slide the supplied R-series tray into a hot-swap bay on any compatible server such as the 1950, 2950, R900 or MD3000. The drive uses a standard SAS connector so no cables or adapters are required. Common issues arise when the backplane firmware is outdated or when the controller does not recognise the 15 000 RPM spindle, so verify firmware levels before installing.

Questions about this item

Will the included R Series caddy fit my PowerEdge 2950 3.5-inch bay?

The supplied R Series caddy is built for Dell PowerEdge servers such as the 2950 and matches the standard 3.5-inch drive bay used in those models.

What is the correct way to connect the SAS drive so the controller sees it?

Attach the SAS data cable to the drive and the backplane or controller port, then seat the caddy firmly until the latch clicks; the common mistake is leaving the latch unlatched, which breaks the connection.

How often should I check the 16 MB cache or mechanical parts on this 15000 RPM drive?

The 16 MB cache is solid-state and needs no service; the 15000 RPM mechanism is sealed, so no routine maintenance is required — replace the drive only if SMART alerts or performance drops appear.
