Small silver 2.5 inch SAS hard drive mounted in a black server caddy tray

IBM

IBM MK3001GRRB 300GB 15000RPM 2.5" SAS 64MB internal hard drive

SKU CH-CRW9-3FZF1

300 GB, 15,000 RPM SAS drive with 64 MB cache and 2.5 inch hot-swap tray included

  • 15000 RPM rotational speed for fast data access
  • 64 MB buffer to smooth burst workloads
  • 6 Gb/s SAS interface for reliable server connectivity
  • 5 inch form factor fits dense drive bays
  • Includes SYSTEM X caddy tray for hot-swap installation

300 GB 15 000 RPM SAS drive

The IBM MK3001GRRB is a 2.5-inch internal hard drive built for enterprise servers and storage arrays. It spins at 15 000 RPM and connects through a 6 Gb/s SAS interface with a 64 MB cache. A hot-swap caddy is included for quick installation in compatible SYSTEM X bays. The 300 GB capacity suits transactional workloads that demand low latency.

Suits high-IOPS server workloads

Database administrators and virtualization hosts benefit from the 15 000 RPM spindle speed and SAS dual-port architecture. The drive is not for desktop PCs or laptops that lack a SAS backplane and hot-swap infrastructure. It also does not meet the needs of users who require terabyte-scale capacity in a single bay. Cooling and power delivery must match enterprise chassis specifications.

6 Gb/s SAS interface decides fit

The single specification that determines compatibility is the 6 Gb/s SAS interface; the host controller and backplane must support this signalling rate and the 2.5-inch hot-swap form factor. Without a SAS-enabled server chassis the drive cannot be used. Verify the part numbers 81Y9670, 81Y9671 and 81Y3812 against your system documentation before purchase.

Questions sur cet article

How does the 15000 RPM speed affect real-world server performance?

The 15000 RPM spindle delivers low latency and high sustained throughput for transaction-heavy workloads such as databases and virtualisation hosts.

What does the SAS 6Gb/s interface limit in practice?

The SAS 6Gb/s link caps maximum transfer rate at 6 Gbit/s per port, so sequential reads and writes cannot exceed that bandwidth ceiling.

Will the included SYSTEM X caddy fit a standard 2.5 inch drive bay?

Yes, the supplied SYSTEM X caddy adapts the 2.5 inch drive to the hot-swap tray used in compatible IBM System x servers.
