Internal 3.5" IBM 146GB 15K SAS HDD — 15000 RPM, SAS interface, 3.5-inch form factor

IBM internal 3.5" 146GB 15K SAS HDD is an enterprise-class hard drive engineered for high-throughput server and storage environments. With a 3.5-inch form factor, 146 GB formatted capacity and a 15,000 RPM spindle speed, this drive uses a Serial Attached SCSI (SAS) interface to deliver low latency and consistent sustained I/O. It is designed to meet demands of transactional workloads, database systems, virtualization hosts and RAID arrays where predictable performance and reliability are required.

Advantages

The drive combines a high rotational speed and SAS connectivity to provide fast seek times and steady data transfer rates under heavy load. Enterprise-focused design practices yield improved durability and error management compared with consumer drives, while compatibility with server chassis and storage enclosures supports straightforward integration. Its mechanical and interface characteristics suit mixed workload profiles that require both random I/O responsiveness and steady sequential throughput.

Suitable for

• Database servers and OLTP systems requiring low-latency random I/O
• Virtualization hosts where multiple VMs create concurrent disk activity
• RAID arrays (RAID 1, 5, 6, 10) for fault tolerance and capacity planning
• High-transaction storage tiers in SAN and DAS configurations
• Enterprise backup appliances and application servers with sustained I/O

Key specifications

• Form factor: 3.5-inch
• Capacity: 146 GB
• Rotational speed: 15,000 RPM
• Interface: SAS (Serial Attached SCSI)
• Optimized for: transactional and mixed workloads
• Typical use case: server and storage array integration

How to use

Install the drive into a compatible 3.5-inch server bay or storage enclosure that supports SAS connectivity. Ensure the host controller and backplane support SAS drives and the required link speed. When adding to an existing array, follow your RAID controller vendor's recommended procedure for drive replacement or expansion to avoid data loss. Initialize and format the drive according to your operating system or storage management software, and monitor drive health with S.M.A.R.T. and hardware monitoring tools available in your server management environment.

Usage recommendations

For best results, pair this 15K SAS drive with enterprise-grade RAID controllers and consistent monitoring. Use it in tiers where low latency and sustained IOPS are required, avoid using it as a cold storage medium, and follow manufacturer guidance for firmware updates and rebuild procedures to maintain reliability.
