Latest Patents

One of Xu Huang's latest patents is titled "Speculative read regulation in hard disk drives having read reliability budgets." This patent describes systems, devices, and methods for regulating speculative reading in hard disk drives that operate under a read reliability budget. The regulation process involves selecting an appropriate amount of read look ahead (RLA) based on whether the read rate exceeds the established reliability budget. When the read rate is below the budget, a full RLA can be utilized to ensure optimal performance. Conversely, if the read rate surpasses the budget, the RLA can be adjusted downward while still maintaining acceptable performance levels. Adjustments to the RLA can occur at regular intervals and can be influenced by the nature of the workload, whether it is more sequential or random.

Another significant patent by Xu Huang is "Latent multiplicity detection." This implementation provides a method for receiving a command from a host, which includes a starting logical block address (LBA) and a command length. The process generates a multiplicity bit mask (MBM) for the command and stores it in an MBM table corresponding to the relevant stream.
