IBM ExS HDD 300GB 15K 6Gbps SAS 3.5" 49Y3727-RFB

The IBM ExS HDD 300GB 15K 6Gbps SAS 3.5" 49Y3727-RFB is a 300 GB serial-attached SCSI (SAS) hard disk designed for server and enterprise storage environments. It operates at 15,000 RPM and connects via a 6 Gbps SAS interface, providing low-latency, high-throughput access for data-intensive workloads. The 3.5" form factor makes it compatible with many rack and tower storage enclosures where high spindle speed and predictable performance are required.

Advantages

This IBM 49Y3727-RFB drive delivers consistent rotational speed of 15,000 RPM and a 6 Gbps SAS interface for efficient data transfer and reduced access times. Its 300 GB capacity balances storage density with performance for mixed workload scenarios. The 3.5" format supports common enterprise drive bays and hot-swap trays used in servers and storage arrays. The drive is intended to provide reliable, sustained performance for applications that prioritize IO responsiveness over maximum capacity.

Suitable for

• Database servers requiring low-latency random I/O
• Transactional applications and virtualization hosts
• RAID arrays and high-performance storage tiers
• Backup and archive systems where performance is prioritized
