IBM 146GB 15000RPM SAS 2.5 internal hard drive

SKU CH-45XA-D3NYT

A 146 GB 15,000 RPM SAS internal hard drive in a 2.5-inch hot-swap form factor with 16 MB buffer and 600 MB/s transfer rate

  • 146 GB capacity stores critical enterprise datasets
  • 15 000 RPM spindle speed delivers rapid data access
  • SAS interface supports 600 MB/s external transfer rate
  • 5 inch hot-swap form factor enables tool-less drive replacement
  • 9 ms average seek time reduces latency for transaction workloads

IBM 146GB 15K SAS-2 Drive

This IBM 146GB 15K rpm SAS-2 drive fits 2.5-inch internal bays and supports hot-swap operation. It spins at 15000RPM with a 600MB/s external transfer rate and a 16MB buffer. The part number 44W2294 identifies a genuine IBM unit supplied in retail or OEM packaging.

Suited For High-IO Workloads

Servers and blade systems that demand low latency and sustained random access benefit from the 2.9 ms seek time and 2ms average latency. Builders needing larger capacity per bay or a different interface should evaluate other options.

Sustained Load Behaviour

The 15000RPM spindle maintains throughput during extended read-write sequences rather than only in short bursts. Hot-swap capability allows replacement without powering down the enclosure. The SAS-2 interface keeps command queuing efficient under continuous queue depth.

Highlights

Questions about this item

Does this 2.5 inch SAS-2 drive require a 2.5 inch SAS hot-swap bay or can it use a 3.5 inch adapter?

The drive uses a 2.5 inch form factor and supports hot-swap; it must be installed in a compatible 2.5 inch SAS hot-swap bay or a 2.5-to-3.5 inch adapter that passes the SAS signal.

Will this 15 000 RPM SAS-2 drive negotiate down to 3 Gbps when connected to an older SAS-1 controller?

The drive runs on a SAS-2 interface rated at 600 MB/s; SAS-2 devices typically negotiate link speed with the controller, so an older SAS-1 controller would limit the link to its maximum rate.

How can I confirm the 146 GB drive is operating at its rated 15 000 RPM after installation?

Use the server's RAID or HBA management utility to verify the reported spindle speed shows 15 000 RPM and that the drive identifies as the correct part number.
