IBM 36 GB 3.5" 15000 RPM SAS internal hard drive

36 GB 15 000 RPM SAS drive

This 36 GB, 3.5-inch internal hard drive spins at 15 000 RPM and connects through a SAS 3 Gb/s interface. An 8 MB cache supports the high spindle speed for transaction-heavy workloads. The unit is supplied new in retail or OEM packaging. It is designed for servers and workstations that prioritise low latency over raw capacity.

Suits high-IOPS database and logging tasks

Database administrators and system builders who need fast random access for small working sets will benefit from the 15 000 RPM spindle. Users who require large sequential throughput or multi-terabyte storage pools should consider higher-capacity alternatives. The SAS interface also limits direct connection to typical consumer desktop motherboards without a dedicated controller.

15 000 RPM spindle speed

The 15 000 RPM rotational speed is the defining specification that determines whether this drive meets a workload's latency requirements. It delivers the short access times needed for intensive OLTP databases and high-frequency logging. If the application can tolerate slower seek performance, a lower-RPM drive with greater capacity may be more appropriate.
