2.5 inch SAS hard drive in black metal caddy

DELL

DELL MK3001GRRB 300GB 15K RPM 6Gb/s 2.5" SAS internal hard drive

SKU CH-5JEK-CT3SR

A 300 GB, 15 000 RPM SAS drive with 32 MB cache and included 2.5" caddy

  • Enterprise 15,000 RPM SAS speed for rapid data access
  • 300 GB capacity supports demanding server workloads
  • 32 MB cache boosts burst transfer performance
  • 5 inch SAS 6Gb/s interface fits dense drive bays
  • Includes R Series caddy for direct Dell server installation

300 GB 15 K RPM SAS drive

This 2.5-inch SAS hard drive delivers 300 GB of storage on a 6 Gb/s interface with a 32 MB cache. The 15 000 RPM spindle speed targets high-transaction workloads in enterprise arrays. It ships in a factory-sealed R Series caddy ready for hot-swap bays.

Suits transaction-heavy servers, not bulk storage

Database servers and OLTP platforms that need low-latency random I/O will benefit from the spindle speed and SAS dual-port connectivity. Builders who need terabytes of inexpensive capacity or silent desktop operation should choose a different drive class.

Sustained enterprise workloads

The 15 000 RPM motor maintains consistent throughput during extended write-heavy batches, while the 32 MB buffer absorbs burst traffic without throttling. Dual-port SAS provides path redundancy so the drive stays online during controller or cable events.

Questions about this item

Does my server or workstation need a 2.5" SAS 6Gb/s backplane or HBA to use the MK3001GRRB?

Yes, the drive uses a 2.5" SAS 6Gb/s interface and requires a compatible SAS backplane or host bus adapter; the included R Series caddy fits Dell PowerEdge bays designed for that connector.

Can the 15000RPM MK3001GRRB share a SAS backplane with older 2.5" SAS drives that run at 3Gb/s?

The drive supports 6Gb/s SAS and will negotiate down to 3Gb/s on a legacy backplane, so it can operate alongside slower 2.5" SAS drives on the same controller.

How can I confirm the MK3001GRRB is running at its rated 15000RPM after installation?

Check the drive’s reported rotational speed in the RAID controller BIOS, iDRAC, or SMART data — it should show 15000RPM and a 6Gb/s link rate if the SAS connection is healthy.
