Described are systems, devices and methods for regulating speculative reading in a hard disk drive that has a read reliability budget. Regulating speculative reading under a read reliability budget involves selecting an amount of read look ahead (RLA) in response to determining whether or not a read rate exceeds the read reliability budget. When the read rate is lower than the read reliability budget, a full RLA amount can be used, thus ensuring high performance. When the read rate exceeds the read reliability budget, the RLA amount can be adjusted down while maintaining performance at acceptable levels. Adjustments to RLA may be made at periodic intervals, and in response to whether the workload is more sequential or more random.

Implementations disclosed herein provide a method of receiving a command from a host, the command providing a starting logical block address (LBA) and a length of the command, generating a multiplicity bit mask (MBM) for the command in response to receiving a command from a host, and storing the MBM to an MBM table in a row corresponding to a stream that the command is part of.

A semi-submersible platform that is suitable to serve as a logistics hub at a remote offshore location. The semi-submersible platform is configured in a V-shape to reduce motion of the semi-submersible platform caused by rough sea conditions. The semi-submersible platform has a vessel docking area within the platform and a balancing unit to balance the unsymmetrical load of the platform that protects a vessel in the docking area from rough sea conditions.
