IBM - 00W1239 - IBM 900GB 10,000 rpm 6Gb SAS 2.5" HDD DS3524

IBM 00W1239 900GB 10K SAS 2.5" HDD for DS3524

The IBM 00W1239 is a 2.5-inch enterprise hard drive delivering 900GB capacity at 10,000 rpm over a 6Gb SAS interface. It is designed for IBM System Storage environments where consistent I/O performance and predictable latency are important for controller-managed disk pools and RAID-protected volumes.

This drive is commonly deployed in IBM System Storage DS3524 configurations and is typically used as a like-for-like replacement or capacity expansion option to keep drive class consistent across existing shelves. For broader platform sourcing and lifecycle planning across your storage estate, see related IBM hardware options.

In most DS3000/DS3500-style deployments, this HDD operates behind storage controllers where matching capacity, speed and interface helps maintain consistent rebuild behaviour and pool performance. Depending on your controller platform and configuration, it is commonly paired with an enterprise RAID CONTROLLER for redundancy and operational continuity.

Key Features

Key technical characteristics for professional storage maintenance and expansion planning:

• 900GB capacity to expand mid-tier storage without changing drive class within existing pools.
• 10,000 rpm spindle speed to support stronger random I/O performance than nearline HDD tiers.
• 6Gb SAS interface to ensure compatibility with SAS backplanes and controller shelves in supported systems.
• 2.5-inch SFF form factor to fit dense storage shelves and SFF drive bays used in enterprise environments.
• Compatibility with IBM System Storage DS3524 to maintain consistent drive type within existing disk pools.
• Suitable for IBM DS3000/DS3500 family practices (for example DS3524) to simplify spares management and standardisation.
• Designed for operation behind storage controllers in RAID-protected groups to support predictable recovery workflows.
• Enterprise-oriented design for 24/7 operation to support continuous workloads in data centres and service-provider environments.

Refurbished Quality and Warranty

This is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished drives are a practical way to extend the lifecycle of existing IBM storage platforms, reduce electronic waste, and control budget compared to buying new.

All products include a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a three-month warranty). Extended warranty options are available on request. Direct Hardware Supply is an international supplier of refurbished IT hardware, shipping worldwide from Denmark.

For installation planning, ensure the correct mounting and carrier requirements for your shelf; compatible mounting options are available in the CADDY category. If you are standardising on flash tiers for different performance profiles, consider alternatives from the SSD category.
