Table 105: Streaming Performance Parameters Log; Table 106: Sector Time Array Entry (Linearly Interpolated); Table 107: Access Time Array Entry (Linearly Interpolated) - Hitachi HTS542525K9SA00 Specifications

The host should base its calculations on the larger of its Typical Host Interface Sector Time and the device reported
Sector Time values, and on the sum of the device reported Access Time values and any additional latency that only
the host is aware of (e.g. host command overhead, etc.).
